Legitimacy of the Founder Effect
To further investigate this question, one must delve deeper into understanding not only the Founder Effect, but the interplay between Genetic Drift and Natural Selection as well. All of these factors occur to help perpetuate speciation. Speciation can occur when one or more daughter groups are isolated from the founding group, or the founding group itself branches into two or more extant populations that are isolated enough from each other to speciate. There are four main methods of speciation, ranging from complete geographic isolation, to mostly geographic, somewhat geographic, and finally no geographic barriers at all. Island populations that suddenly get cut off from the mainland when sea levels rise speciate due to complete isolation. Some species evolve to occupy certain ecological niches within the same geographic area. For example, perhaps a mutation for a slightly thicker bill in an outlying area within the same geographic boundaries results in a finch that has a thicker bill and perhaps the ability to extract insects from dead bark. This group then eventually exploits the rotten wood insect niche throughout the initial geographic range.
Genetic drift then is the random rate of variation that occurs within a given population and depending on the initial numbers and environmental conditions can be either kept in check by Natural Selection or allowed to proceed. Smaller populations are more likely to undergo genetic drift because of the limited genetic diversity, while larger populations intermix well and barring environmental changes that open new ecological niches for certain groups within the population to occupy leave little room for major drift. Natural Selection functions by allowing only those alleles that are biologically or reproductively adaptive to perpetuate, while genetic drift is just the random shuffling of alleles mostly irrespective of the adaptive pressure. Examples of Genetic Drift in Humans can include epicanthic folds in the eyes of Asians, increased hairiness in the bodies of Mediterraneans or Okinawans, Blond Hair and Blue Eyes in Scandinavians, wavy hair in Polynesians, and etc. Examples of Natural Selection in Humans on the other hand include darker or lighter skin, thicker, stockier builds in colder regions, barrel flared chests in Andean and Himalayan people, reduction of perspiration in Australian Aborigines, etc. It must further be noted that not all of these human characteristics are strictly a result of natural selection or genetic drift, some are a product of the interplay between the two forces.
Coming back to the Founder Effect then, we can look at a hypothesis as to how New World Monkeys came to Occupy the Americas when in fact, there was already a large gap between the continents when their ancestors branched from their African counterparts. It has been established, through the fossil record, and mitochondrial analysis that New World Monkeys emerged approximately 35 million years ago (link), during the early oligocene. At the time, the geographic distance between Africa and South America was at least 1300 miles (link) and therefore, quite a barrier for a founding population of pioneering monkeys. Vegetative Rafting has been proposed as a solution to the large oceanic gap that was bridged by these accidental voyagers. Due to the large volume of water discharged in the rainy season within Tropical locales, occasionally large swaths of vegetation get swept out to sea by huge rivers like the Amazon or the Congo. These vegetative rafts then float hundreds of miles out to sea, usually drying up. However, with prevailing winds and currents, some of these rafts can travel quite far, and this is the possible scenario that lead to the ocean voyage of some African Monkeys. This initial founder population then must have been very limited, perhaps a half dozen individuals. The genetic analysis has shown that they all originated from a small group of founders (just like a population bottleneck) but because of the rich geographic and environmental diversity, their populations exploded and speciated. In particular, population drift probably had a very large role to play in the diversity of current New World Monkeys and the ecological niches they occupy. The Question again is how this small founding population, with limited genetic diversity, blossomed into numerous species, irrespective of the initial inbreeding that could have resulted in numerous lethal alleles and population crashes. Several possible theories are likely, but none definitively stand out. Perhaps some animals are better able to cope with limited genetic diversity. Or, perhaps the new ecological niches helped increase the rate of speciation and variation within the population. Given that Genetic Drift had a large part to play with the small founding population, how did that effect the likelihood that lethal alleles were mitigated.
Such questions are the reason why Evolutionary Biology is such a fascinating field of study, and rarely are answers as complete as one would like. However, should anybody reading this have better knowledge on any of these topics or answers to my questions, please e-mail me or let me know in the responses what possible theories or holes in my reasoning can help to further illuminate this subject.

**02/17/2009 Update
The possible role of r/K selection in the founder effect.
The concept of r/K selection describes the selection of certain traits which promote success in particular environments. It comes about from an algebraic equation related to population dynamics. In general, species that are K strategists have increased investment in fewer offspring, while r strategists maximize the amount of offspring with as little investment as possible. Competition is the major key differentiating these two strategies. Since r strategists have little competition, they can focus on increasing their numbers as quickly as possible. Yet, once competition pressures increase as new species come about, other strategies, such as more investment in less offspring, evolve to cope. Ultimately, an ecological balance is reached between r and K strategists. From this, the relevance to the founder effect seems intuitive. Founder species, especially those like the ancestors of New World monkeys must have been r strategists. Finding themselves in an environment with countless niches, they must have reproduced quickly and evolved to fill them. Once enough speciation occurred to sufficiently increase competition, some monkey species may have adapted towards K selection.
Still, even though we can identify the ecological process that r/K selection plays within the founder effect, we must still explain the eventual success after the initial lack of genetic variability. Perhaps r strategists, with their hi fecundity, mutate rapidly enough that their genetic diversity is readily expanded within a few hundred generations, reaching a critical threshold when lethal alleles are balanced with genetic variability. The critical number of founders certainly differs among species, with those that are K-strategists probably requiring a larger gene initial gene pool. It's also possible that some species, regardless of their ecological strategies, are naturally prone to greater mutations; perhaps a less accurate DNA repair machinery, or environmental constraints that increase the adaptive advantage of survival through increased offspring variability.

The Embrace of Atheism

Comfort in a warm religious blanket
Of the various evolutionary traits that may provide the proximal outcome for religious belief, comfort and authority may be the most salient. As Richard Dawkins discusses in the God Delusion, authority is ingrained in us since childhood because it aids in our survival. Human children are born so helpless, that only through direct exposure in a culture, will they develop to their evolutionary potential. The initial learning required to effectively navigate through life, and therefore propagate to the optimal potential, requires at least two decades in human beings. We are social creatures, and with so much danger in the world, we're born with built in authority seekers. We need to learn from the experience of those older then us, especially parents, during our formative years. Perhaps this receptive ability towards authority when we're young blinds us to continue following authority when we're older. Certain traits don't necessarily shut off just because of an age difference. Although important for survival in our youth, this trait has lead us astray when we seek to follow those with authority who may actually not have our best interest in mind. For example, a parent might tell a child not to poke a sleeping bear with a stick, and if the child does not listen, then natural selection will effectively cull this trait from the gene pool. As the same child becomes an adult, perhaps the village chief will tell this individual that the only way the rains will return is if he pokes a bear with a stick. Now, this act is not in the best interest of the individual, but because of the authority seeking ability ingrained in us, most will do as told.
Another evolutionary trait that must be discussed is our need for comfort. This may not seem as discrete a trait as that of authority seeking, but it has a very large part to play with our persistent religious beliefs in the face of so much contrary evidence. As a species, feeling security is tantamount to survival. If there are large land predators around, then the security of a tree will aid in the survival of the individual. Similarly, as humans evolved from an arboreal species to a terrestrial species, we relied more and more on creative solutions to seek comfort. Various examples include enclosed dwellings, such as caves, or ones that we create ourselves, such as houses. Since we're able to control fire, this gives us an added feeling of comfort and security. As most mammals, it is ingrained in us to seek the shelter and comfort of our parents. Just as one cannot turn off the need for authority as an adult, one cannot just turn off the need for comfort either. Religion to some extent provides this safe cozy blanket that shields us from the harsh world around. It gives authority to the supernatural, and we justifiably feel safe from the cold reality of the world. Whether believers feel obliged to seek comfort in a singular authority like God (as in monotheists like Christians, Muslims, Jews, Sikhs, etc), or a varied scope like the Hindus (among other polytheists), they share the need for some comforting authority. Even among animists (non organized religion, or folk religion), like the folk religion of most early hunter-gatherers, they often sought comfort with the belief that their dead ancestors had control over their lives.
With comfort and authority in mind, it becomes partly obvious why people across different cultures reach to the supernatural when faced with so much contrary logic. Science cannot provide the same warm comforts, at least psychologically, that religion can. When one bases their belief in the physical world that we live in, it's somewhat disconcerting to realize that there isn't an omniscient and omnipotent authority figure looking after one's best interest. Conversely, without such an authority figure, it frees us to seek guidance in the realm of science and the laws of the universe. The meaning of life can change from "God wanted me on Earth" to "How do I understand the physical processes of this amazing and vast universe that I live in?" When one is freed from the bonds of religion and authority, the freedom that's available is refreshing. There may be a part that misses that warm comforting blanket, the reassuring being(s) looking out for one's best interest, but even then, it doesn't make the existence of a higher power more likely. Just because there is a need in people to feel comfort and security even in their adult years, it still doesn't necessitate the supernatural. For example, if a billion people on the planet think and need to believe that God created the Earth as the center of the universe for it's sheer importance, it doesn't change the fact that this belief is wrong. We know that the Earth is just the third planet, from a negligible star, in an ordinary corner of an ordinary galaxy and no matter how much one would like to believe otherwise, science through its empirical methods and scientific reasoning has shown us the truth.
One must therefore strive to seek comfort and security in the physical world as we know it. Some may argue that it's arrogant to think we evolved through natural selection and random chance mutations. Instead, these people think that we must submit ourselves to the will of some entity that is largely a creation of our amazing imaginations and our need for comfort and authority. Others will have spent years of their life in a religious institution that has never been able to properly investigate the universe around us. Without a deep understanding of the physical, biological, and chemical processes that makes our existence possible, how can one understand life? This is the ultimate reason why those of us who have embraced science to the fullest have no regrets or empty voids that must be filled through some supernatural means. Comfort is nice, blankets are warm, but without shedding the blanket and investigating our environment, we are no different than creatures which we consider inferior to our intellect.

Progress from Genocide Denial??!!?!!
Having largely described the progressive trends that has been described as a Zeitgest (German for current at some point in time), it becomes clear why the thought of another event with mass casualties and large scale warfare like that from WWII is harder and harder to imagine. Hopefully, diplomacy is starting to win out over the need to launch such global scale wars. In fact, the unfavorable opinion of many from the current Iraq war makes us realize the loss of life to such ill conceived wars is become more and more unbearable to people. Thought the loss of life from Iraq from a military standpoint is less that that from the Vietnam war, people are less tolerant of such casualties. Furthermore, the loss of civilian life cannot be underestimated. We now have a deeper understanding of just how many lives these wars cost, thanks to a larger net of global information.
With social progress in mind, we must never forget how far we've come ethically and morally. In order to continue to move forward, we must accept our previous moral indiscretions and move on accordingly. This is why the Armenian Genocide Resolution in Congress is such an important event in the minds of many Armenians. The Turkish Government fears that recognition of the Genocide will result in restitutions to the families of the survivors. The truth is, restitution aside, it's our moral duty and obligation as human beings to begin to accept such acts and bear personal responsibility for such events. Another issue in Turkish denial is that the Modern Turkish people cannot fathom how their ancestors were able to accomplish such an act when they themselves have progressed. Yes, there are extremist elements in Turkey, and the Kurds are to some extent suffering similar fates, but even so, most enlightened Turks can't imagine massacring a people and culture. Yet, the overwhelming evidence, and the total destruction of the Armenian presence in Eastern Turkey is pretty damning and conclusive evidence as to which culture was on the wrong side of the Genocide. If Turkey was truly objective, why go to all the trouble erasing the past as it pertains to Armenians?
Worse then the Turkish denial, was what seemed to be the silent approval by certain allies of Turkey (Such as the United States and Israel, oh the Irony) because ultimately, Turkey provided friendlier to the interests of those states then other nations in the area. During the Cold War, Turkey was critical in Containing the Soviet Union, and helping support Israel. Since the collapse of the Soviet Union, Turkey has allowed itself to be further exploited by the West for profit. Our ethics and morality,especially in the sphere of government, obviously haven't evolved to where the majority think that profit is less important then the well being of others.
Granted, some may argue that due to current circumstances of the volatile Middle East region, acceptance of the Armenian Genocide measure by Congress will endanger the American Troops, and give free reign for Turkey to behave according to national interests. Well, if that's how an American ally will behave, "threatening to endanger our troops", then they aren't really allies in the first place (brings to mind that quote, "with friends like these, who needs enemies"). Besides, waiting for a perfect moment of acceptance of the measure will never occur, because the world is always in a state of flux, and there never is a perfect moment. As sure as the Germans recognized the Holocaust then, the Turks must recognize the Armenian Genocide. Some Cynics will argue that should the Armenian Genocide be accepted, then why not the Hawaiian Genocide, the Native American Genocide, the current Darfur Genocide, among many others. Well, why not accept all these events as genocide and move on. Throughout history, it has been shown again and again that there will always be powerful states, or societies trying to destroy weaker ones. Some are done in the name of god or gods, others in the name of the holy land (nationalism), still others in the name of xenophobia, internal strife, etc. Yet, all these events have a common link and that is that we must recognize so that we can move forward.
Should the Armenian Genocide Resolution not pass the House, or be blocked as it has been in the past, then whatever values those in Congress who didn't support the measure purport to have are completely groundless. The level of hypocrisy among these supposed progressive individuals is staggering. Ultimately, this isn't just a resolution for Armenians, it allows others who have been effected by such measures, such as the Japanese who were interred in US concentration camps during WWII, or Native Americans, Native Hawaiians, African Americans, to come together and build a coalition to prevent such tragedies from every happening again and stop those that are currently in progress (Palestine, Sudan, Zimbabwe, Iraq.....)
It is my hope that humanity will view the early 21st century as the critical moment in time when people stopped living for materialism or hatred of others, but progressed to accept all of humanity as a singular race. We as a species are obligated to help not only each other, but the world that we live in. We must accept and in due course, progress further from these shackles which restrain us to our past. Will civilized discourse and diplomacy win over war and genocide? Will we remain ignorant of other's inalienable right to freedom? Well progress lead us to view our current times as we now view the Middle Ages? Will we stop viewing the world in Black and White, and start reasonably assessing the gray areas in between? These, and many other similar questions should be on the forefront of everyones mind.

Revolutionary New Punctuation Mark
Irony and sarcasm, are often lost on the written form. Some forms, such as satire, are nuanced, and they feed on the confusion and difficulties in understanding it. Other forms of irony, such as sarcasm, can often go unnoticed, and frequently the intention of the author is completely misconstrued due to a misunderstanding of tone. Through spoken word, we can inflect various parts of the sentence, to reflect the sarcasm, or irony that we seek. However, written, it becomes very difficult to determine the moment of inflection and therefore, it is frequently improperly interpreted.
My solution would be the addition of a New Punctuation Mark, I shall call the IRONY MARK. Looking at the keyboard, there is a symbol that is infrequently used, and can substitute, if not be eventually used as the Irony Mark. This would be the "~" symbol. Also, borrowing from the Armenian written language, where the punctuation mark is not placed at the end of the sentence, but at the point of inflection, the ~ symbol would be placed within the sentence, where the turn of voice would occur. For example, in English, one would say "Does anybody know where the car is?", but in Armenian, the question mark (which is a different symbol) would be placed where the voice is inflected within the sentence. Does anybody know? where the car is. Furthermore, the inflection could be on another part of the sentence, and therefore, the question mark would be adjusted accordingly. One could also say "Does? anybody know where the car is. Or "Does anybody? know where the car is. Or even, Does anybody know where the car? is.
Having considered the previous examples, we can therefore attempt to determine how one would use the Irony mark. Would we place it, like the question mark in English, at the end of the sentence,? Or, should we place it where the inflection of the voice occurs? For example, the statement "Through his amazing insight, he was able to locate the car after 3 hours" would probably be used sarcastically. Therefore, the Irony mark could be used as follows: "Through his amazing~ insight, he was able to locate the car after 3 hours". If we would place the Irony mark at the end of the sentence, it would still be recognized as a sarcastic statement, but the nuance and subtle voice chance would be lost. What is irony without the powerful tool of the subtle change of voice? We could also use the Irony mark where it would be even more necessary. For example "The garden tomatoes were the best~ tasting ones I've ever~ had." Here, we could use two Irony marks to recognize that this statement was truly a sarcastic remark. A final example to illustrate the need of the Irony mark will highlight why it should be used for more then just sarcasm. In a situational Irony, the Irony mark could be used to enhance and "flavor" a statement. "Even in the worst of times, she had~ to be a hard worker because very few were able to determine just how she was able to purchase the new mansion down the street." Here, the irony in this situation is itself located with the Irony mark. This sentence can now be read with suspicion of some form of unmentioned implication. The irony in this example, would be that she wasn't a hard worker, and must have earned the money for the mansion through some means as yet unmentioned and perhaps sinister or clandestine. The purists will say that subtlety will be lost with the irony mark, but I believe that with any loss, there can also be benefits. Determining if the benefits outweigh the losses will be up to those who can perpetuate this new Punctuation Mark. Perhaps it will be used only informally, but I believe that even then, it can add to the richness and variety of the written language

Limits on Perception and Scope
Certainly, from the evolution of our modern brain, particular traits were perpetuated, which counter the immense world that we are bombarded with on a daily basis. In essence, our brains are limited in both Perception and Scope from the knowledge which we obtain on a daily basis. We have a difficult time discerning things that are too far from our perceptional and reasoning abilities. Quantum Mechanics for example, in many ways is counterintuitive to our daily experience, because we are creatures of a larger level. If we exponentially increase the scale of our experiences, at a greater macro level, then even those levels which we can comprehend become counterintuitive. In general, if we look at the physical world at the smallest subatomic scales, then most of what we know as solid, is empty space. An atom is, for the most part, nearly empty. At the same time, if we increase the scale of our experience to that which involves galactic clusters, then most of space as we know it is itself empty as well. In fact, only 4% of the universe is made of luminous matter -- that which we can see and interact with.
Having discussed the ramifications of our limited biological brains in processing the physical universe (especially in scales that we don't encounter on a daily life), even our processing abilities on our own humanistic level is suspect. We as a species evolved, along with our brains, to interact with small clans, and analyze other groups on a limited level. It becomes immensely difficult when we decide to analyze a population that's larger then our brains biological tolerance limit. For example, economics is a difficult subject, specifically because in some ways it's an emergent phenomenon. From the actions of individuals, to actions of small groups, to larger groups, eventually a large-scale phenomenon is developed, that can be applied globally. Yet at this level, simple analysis fails us, because of certain emergent properties of large scale chaotic behavior. Just as nearly empty space at the subatomic level can lead to physical interactions that we, at our middle level are aware of, certain small scale trends can eventually lead to a higher system that seems independent in some ways. Typically, this is what's considered an emergent property. Similarly, the neurons in our brain, simulate the real physical world around us, and in doing so, activate what we know as thought, or consciousness. The exact mechanism is still unknown, but chances are, emergent phenomenon are at play. From what may be gathered, Emergent Properties, are aspects of our attempts at defining phenomenon that exceed our scopes and perceptions.
Looking at various examples that we encounter on a daily basis, can help illuminate us, into the limitations on our mental scope. First, let's consider the information from the rest of the world that we're bombarded with on a daily basis. Looking through various web sites that suit our needs, we are exposed to news of wars, famine, celebrity gossip, disease, mass death, plane crashes half a world away, natural disasters, etc. We have become global information filters, and initially, it may seem normal, but having evolved as small hunter and gatherer clans, it's mentally very taxing trying to keep up with all the global information. The mentally taxing aspect comes from having to deal with phenomenon that are beyond our mental scope. This is not to say that we cannot achieve some form of understanding, but it becomes harder and harder, with more inclusive information. Secondly, we can look at our individual daily interactions and realize how limited we are in scope. Police for example deal with a proportionally higher criminal element then for example, butchers. In that respect, an officer can perceive the whole world as more criminally biased, then a butcher. In the same token, a gastroenterologist, because of his daily interaction with ulcerative patients, will assume that a greater proportion of the population suffers, then the actual number of people. Ultimately then, SCIENCE frees us of these patterns of thought. A doctor can look at research papers that illustrate just how many percent of the population suffers from ulcers. Even with his limited scope, his reliance on science will help keep in unbiased and retain some measure of true perspective. Similarly, an officer can look at certain crime statistics and realize that although it appears that murders seem to have increased, maybe his interaction with certain cases make it seem so, when in fact, they're on the decline.
Ultimately, our reliance on empirical evidence and the scientific principle wills us to achieve perceptional ability and scope beyond our limited examples. Although the information that we receive may be excessive, and our mind may strain to understand counterintuitive properties of the universe, or subatomic matter, economics, consciousness, or even linguistic development, we will ultimately benefit from the accumulated wealth of scientific knowledge. Irrational beliefs (I'm not going to mention religion, even though I just did), are often a result of our limited scope and perception. Though difficult, we can break free of our mental chains, by allowing ourselves the freedom of exploring both the large, the small, and the absurd.

From Independence to Tyranny: Downfall of Freedom
IN CONGRESS, JULY 4, 1776
The unanimous Declaration of the thirteen united States of America
When in the Course of human events it becomes necessary for one people to dissolve the political bands which have connected them with another and to assume among the powers of the earth, the separate and equal station to which the Laws of Nature and of Nature’s God entitle them, a decent respect to the opinions of mankind requires that they should declare the causes which impel them to the separation.
(Example: Breaking the Shackles that have bound us to bipartisan Israeli Foreign policy)
(Such as the Tyrannical regime of George W. Bush)
He has refused his Assent to Laws, the most wholesome and necessary for the public good.
He has forbidden his Governors to pass Laws of immediate and pressing importance, unless suspended in their operation till his Assent should be obtained; and when so suspended, he has utterly neglected to attend to them.
He has refused to pass other Laws for the accommodation of large districts of people, unless those people would relinquish the right of Representation in the Legislature, a right inestimable to them and formidable to tyrants only.
He has called together legislative bodies at places unusual, uncomfortable, and distant from the depository of their Public Records, for the sole purpose of fatiguing them into compliance with his measures.
He has dissolved Representative Houses repeatedly, for opposing with manly firmness his invasions on the rights of the people.
He has refused for a long time, after such dissolutions, to cause others to be elected, whereby the Legislative Powers, incapable of Annihilation, have returned to the People at large for their exercise; the State remaining in the mean time exposed to all the dangers of invasion from without, and convulsions within.
(Lack of a 3rd party in politics)
(Immigration reform)
He has obstructed the Administration of Justice by refusing his Assent to Laws for establishing Judiciary Powers.
(Bush Subverting the Supreme Court and the Justice Department)
He has made Judges dependent on his Will alone for the tenure of their offices, and the amount and payment of their salaries.
He has erected a multitude of New Offices, and sent hither swarms of Officers to harass our people and eat out their substance.
He has kept among us, in times of peace, Standing Armies without the Consent of our legislatures.
He has affected to render the Military independent of and superior to the Civil Power.
He has combined with others to subject us to a jurisdiction foreign to our constitution, and unacknowledged by our laws; giving his Assent to their Acts of pretended Legislation:
(Israel Again)
For quartering large bodies of armed troops among us:
For protecting them, by a mock Trial from punishment for any Murders which they should commit on the Inhabitants of these States:
For cutting off our Trade with all parts of the world:
(Cuban Embargo, while Saudis lounge in their oil money)
For imposing Taxes on us without our Consent:
(The Income Tax: non proportioned direct tax which is ILLEGAL)
For depriving us in many cases, of the benefit of Trial by Jury:
(Guantanamo Bay and Secret Prisons in Europe)
For transporting us beyond Seas to be tried for pretended offences:
For abolishing the free System of English Laws in a neighbouring Province, establishing therein an Arbitrary government, and enlarging its Boundaries so as to render it at once an example and fit instrument for introducing the same absolute rule into these Colonies
For taking away our Charters, abolishing our most valuable Laws and altering fundamentally the Forms of our Governments:
(The subversion of our whole constitution by those in power)
For suspending our own Legislatures, and declaring themselves invested with power to legislate for us in all cases whatsoever.
He has abdicated Government here, by declaring us out of his Protection and waging War against us.
He has plundered our seas, ravaged our coasts, burnt our towns, and destroyed the lives of our people.
(We are seriously talking about Bush here)
He is at this time transporting large Armies of foreign Mercenaries to compleat the works of death, desolation, and tyranny, already begun with circumstances of Cruelty & Perfidy scarcely paralleled in the most barbarous ages, and totally unworthy the Head of a civilized nation.
(Supporting "allies" with appalling human rights records)
He has constrained our fellow Citizens taken Captive on the high Seas to bear Arms against their Country, to become the executioners of their friends and Brethren, or to fall themselves by their Hands.
He has excited domestic insurrections amongst us, and has endeavoured to bring on the inhabitants of our frontiers, the merciless Indian Savages whose known rule of warfare, is an undistinguished destruction of all ages, sexes and conditions.
In every stage of these Oppressions We have Petitioned for Redress in the most humble terms: Our repeated Petitions have been answered only by repeated injury. A Prince, whose character is thus marked by every act which may define a Tyrant, is unfit to be the ruler of a free people.
Nor have We been wanting in attentions to our British brethren. We have warned them from time to time of attempts by their legislature to extend an unwarrantable jurisdiction over us. We have reminded them of the circumstances of our emigration and settlement here. We have appealed to their native justice and magnanimity, and we have conjured them by the ties of our common kindred to disavow these usurpations, which would inevitably interrupt our connections and correspondence. They too have been deaf to the voice of justice and of consanguinity. We must, therefore, acquiesce in the necessity, which denounces our Separation, and hold them, as we hold the rest of mankind, Enemies in War, in Peace Friends.
We, therefore, the Representatives of the united States of America, in General Congress, Assembled, appealing to the Supreme Judge of the world for the rectitude of our intentions, do, in the Name, and by Authority of the good People of these Colonies, solemnly publish and declare, That these united Colonies are, and of Right ought to be Free and Independent States, that they are Absolved from all Allegiance to the British Crown, and that all political connection between them and the State of Great Britain, is and ought to be totally dissolved; and that as Free and Independent States, they have full Power to levy War, conclude Peace contract Alliances, establish Commerce, and to do all other Acts and Things which Independent States may of right do. — And for the support of this Declaration, with a firm reliance on the protection of Divine Providence, we mutually pledge to each other our Lives, our Fortunes and our sacred Honor.

Debunking the Religious Right
Having recently reached the limit of the ignorant barrage of rational thought that the Religious Right attempts to feed people, the importance of unweaving the tapestry of garbage and irrationality that they contrive cannot be overstated. We are constantly being inundated with emotional appeals and fear into believing that the only true path (into understanding the universe and our place in it) is through the miraculous salvation of not only spirituality or religion, but through a specific belief system within those realms. Lately, an opinion by someone among the religious right has surfaced that covers many of the myths and topics that these individuals use to coerce those unsure of their place within the cosmos into the ignorant cover of their specific belief structure. The author's attempts to strike an emotional chord with the reading audience are both transparent and pathetic. I shall attempt to debunk his points paragraph by paragraph and provide a rational means for thoughtful debate and discussion. My retort to his views will be in red italics while his will be in standard type-face. Further, the USA Today article that this opinion was presented in will be shown in bold before the philosophical dissection of his ideas. Finally, a few thoughts of my own will be concluded in blue at the tail end of this essay.

Oh, for the days when one could safely stroll into a bookstore without tripping over the latest atheist title. Ironically, by writing their tracts, in the long run atheists might boost belief.
It appears that Feder here is threatened by non-religious views. Through this first paragraph it's apparent that he longs for a time when all one would see in a bookstore would be theological books without views that provided him grief. His turn of phrase stating that these books will boost religious belief does not detract from his impression that the world is better off without questioning religious dogma?
My local Barnes & Noble has the following titles on display -Atheist Manifesto: The Case Against Christianity, Judaism, and Islam ; The Quotable Atheist; Letter To A Christian Nation; God: The Failed Hypothesis: How Science Shows That God Does Not Exist; and The God Delusion, which is a New York Times best-seller.
Of the handful of titles he does state, where is the mention of thousands of books that are religious and theological in nature? A few books with oppositional elements to his viewpoint does not result in a conspiracy to destroy his irrational belief structure. It's just a natural progression towards discourse in a topic that contains much animosity and misunderstanding.
Rep. Pete Stark, D-Calif., has become the first member of Congress to announce that he doesn't believe in God. He's probably just looking for a book deal.
Once again, the author feels a threat to his value system by just one individual. What he fails to mention is that there are 534 other members of congress that DO believe in God. Pete Stark just represents .002% of congress, while the same representative group of Americans who are not convinced of God's existence amounts to a conservative estimate of 9%. Just because there's one confirmed disbeliever against hundreds in Congress does not mean he's looking for a book deal. How cynical must one's opinion be that those parties who disagree with views do so because of superficial monetary reasons. What about all the religious ministers driving around in Top-of-the-line luxury vehicles, and wearing expensive Watches, claiming that everyone is created equal? Book deals are not exclusive to the non-believers. There are plenty of religious people who sign for book deals detailing why they have faith, and why they continue to oppose stem-cell research and abortion.
Why the sudden outpouring of atheist advocacy? Perhaps it's a way for the cultural left to assert itself in the face of the religious right. Or maybe it's meant to show that the anti-God argument can be framed more intelligently than in a Bill Maher monologue. Whatever the impetus, as a believer, I welcome the phenomenon. After all, the great enemy of belief isn't disbelief but indifference.
This paragraph I definitely agree with. There has to be debate about this subject, because otherwise, empty rhetoric like this will continue to coerce others into certain belief structures. This topic must not only be framed in context, but rigorously challenged by both sides of the argument.
Let the godless write their books and the faithful answer them. The disillusionment with religion that dominated British intellectual circles after World War I helped to shape the great Christian apologist C.S. Lewis. The surviving son of atheist icon Madalyn Murray O'Hair is an evangelical Christian.
Unfortunately, Feder does not differentiate between those who are confirmed atheists and those who consider themselves agnostic (who don't deny the existence of a higher power, but don't blindly believe in one either). He lumps all the opposition together in an attempt to frighten others into believing that a great scheme of destroying religious discourse exists. It's his attempts that stifle discourse and polarize groups of people.
The books referenced above assert that the debate is over and that atheism has won, but atheists have been saying that for more than 200 years. Since the French Enlightenment, the death of God has been confidently proclaimed. Religion has been made obsolete by egalitarian revolution, industrialism, or science, they insisted. Yet, early in the 21st century, faith endures.
A fallacy present here is oversimplification of facts. He summarizes nearly a half dozen books into a simple antagonistic phrase "the debate is over, atheism has won". Generally, what these books attempt to provide is a thought process based on rigorous science and subsequently a philosophical paradigm shift into understanding the universe without invoking religious dogma. Of course, it's better to read these books, because I'd be committing the same fallacy if I reduce so much literary energy into a summary of my own.
Outlasting the
For 70-plus years, the Soviets tried everything imaginable to kill religion: show trials, mass murder of clerics, confiscations, indoctrination and even attempts to co-opt religious symbols and ceremonies. But belief survived, while scientific socialism is now defunct.
What the Soviets did was replace Religion with a "cult of personality" in the form of "uncle Lenin" or "Papa Stalin". These figures were no different than religious iconographies. They were revered as saviors, just as some religions revere prophets. Upon decease, Lenin was preserved ON DISPLAY for everyone to see and worship.

As for the hunger for a creator, perhaps this has more to do with the brain than the heart. It is shown that there are regions in the Temporal Lobe of the brain that are devoted to feelings of faith and religious euphoria. This does not mean that it's God's will. Perhaps these structures allow for greater cohesiveness in our social system and provided early man with opportunities to tighten the social bonds which in turn resulted in an environment where our genes would flourish.
What would a world without God look like? Well, for one, morality becomes, if not impossible, exceedingly difficult. "Thou shalt not kill" loses much of its force when reduced from commandment to a suggestion. How inspiring can it be to wake in the morning, look in the mirror, and see an accident of evolutionary history - the end product of the random collision of molecules?
The Universe itself is an amazing place with or without religion. Just the fact that we exist is so highly improbably that we cannot fathom a reason for it. Those who take the easy way out either say that God created things that way (where's the imagination?), or what's the point of discerning things if there is no creator. Both views require a strategic shift in thought. Perhaps it's not about what our purpose of existence is, but where our future lies. Not individual futures, but the future of humanity in general.
A universe that isn't God-centered becomes ego-centered. People come to see choices through the prism of self: what promotes the individual's well-being and happiness. Such a worldview does not naturally lead to benevolence or self-sacrifice.
This paragraph also shows the lack of imagination on the author's part. The universe doesn't necessarily have to become ego-centered because there is something more then the self. As I stated before, there's humanity in general. Attempting to further our cultural evolution and our future as a species is not ego-centered. We now realize, through science, that the environment is highly important because this is the only place in the universe where humans exist. This little blue dot is our planet, and is shared by all of humanity, not just one individual. Self sacrifice and benevolence does not come from religion but from a social environment that's furthered through advancement in technology, thought, science, and self-awareness.
An affirmation of God can lead to the Ten Commandments, the Sermon on the Mount and the Declaration of Independence. In terms of morality, a denial of God leads nowhere.
It's funny how a generalized conversation on religion by those with dogmatic beliefs will always switch into a specific religious view. Here, Feder brings up the Ten Commandments and fragments of HIS religious world view. There are millions of other religions and billions of other people in the world who support views that are completely different. Yet, he claims "denial of God lead nowhere". Who's God is he talking about? Clearly it's the Judeo-Christian God, and not that of other unrelated religious beliefs. Morality is present within us, with or without religion. The ancient Romans had strong moral principles (even though when compared to today's world, they may seem barbaric -- who's to say in 1500 years if people view us as barbaric for eating meat, playing violent video games, fighting wars, supporting capital punishment?), yet they were polytheists. They believed in multiple Gods and yet, they had principles that are dictated by culture and society. We have come a long way from our cave dwelling ancestors, in terms of our moral principles, but that's not because of religion but scientific and technological progress.
There are no secularist counterparts to
Pope John Paul II, Mother Teresa, William Wilberforce (the evangelical responsible for abolition of the British slave trade), Martin Luther King Jr., or the Christians - from
Sure there are. What about all the scientists, engineers, inventors, and numerous others who made the world a better place to live, and expanded on our understanding of our place in the universe. Just a few of the examples (not individuals because the advancement of humanity is not based on individuals but on a collective of individuals working either in groups or from the latest advancement of their predecessors in improving our outlook) include Medicinal Advancement, Industrialization, Safety implementation, Alternative Energy, Economic Reform, and Genetic Engineering that allowed for the Green Revolution, which subsequently helped feed millions if not billions of impoverished around the world.
True, terrible things have been done in the name of religion. Terrible things have been done in the name of every noble concept, including love, charity, loyalty and kinship. Yet, the worst horrors of the modern era were perpetrated by godless political creeds. The death toll from sectarian conflict over the ages is dwarfed by ideological violence, from the Jacobinism of Revolutionary France to the charnel houses of communism and fascism.
As mentioned before, most non-religious regimes replaced religious dogma with cult of personality. What they didn't change is the wiring in the brain that allows for faith, whether in a mythical deity that lives in the heavens constantly watching over and participating in our lives, or a deceased all-powerful leader who helped usher in a new age? These deaths would not have occurred had rationalism prevailed and the understanding that all that we have and all that we are is on this little planet. We are all more similar then dissimilar. We may be insignificant to the greater universe, but not to each other or this planet.
This is not to say that atheism leads naturally to guillotines and gulags, but, just as "love your fellow man as yourself" can be corrupted, so too can liberty, equality and fraternity.
Therefore anything can be corrupted, religious or not. This point I agree with.
Signs throughout history
There is no irrefutable evidence for God's existence or non-existence. But, if you look closely, his footprints can be discerned in the sands of time.
This all depends on one's basic starting premise. If one begins a view from a singular perspective, then all the following will support their opinion. However, if one looks at issues like an astronomer observing the universe, then the bias in an opinion is minimized. For example, the Astronomer must first look, and then theorize, and then attempt to validate those theories. That's why most people believed the Earth to be the center of the universe until the Copernican revolution. They started with the premise that the Earth was the center, so anything observed had to be around the Earth, so they had to introduce greater and greater complexity into their beliefs, until the true nature of our place was discovered.
Jews introduced the world to monotheism. They also were the first people to perceive history as linear- an unfolding story moving toward a conclusion. Is it a coincidence that this tiny, originally nomadic people generated the ideas that shaped the Western world, including equality, human rights and a responsibility to our fellow man? Jews are the only people to maintain their identity during two millennia of exile, and then return to their homeland and re-establish their nation.
The world was introduced to Monotheism well before the Jews. Zoroastrians, before the bastardization of the belief structure in Achemenid Persia, was by and large a monotheistic religion. Also,
Mark Twain wrote: "The Egyptian, the Babylonian, and the Persian rose, filled the planet with sound and splendor, then faded to dream-stuff and passed away; the Greek and the Roman followed, and made a vast noise and they are gone; other peoples have sprung up, held their torch high for a time, but it burned out and they sit in twilight now or have vanished. … All things are mortal but the Jew; all other forces pass, but he remains. What is the secret of his immortality?" Had Twain been a believer, he might have answered his own question.
The secret of immortality of the Jews is with the Bible and Christianity. Judaism is progressed through anyone who attempts to read the Bible, and comes away with a history lesson of the people and places of a certain region of the
Improbably doesn't necessarily translate to God's footprints. Just because something is deemed improbable doesn't mean it is impossible. Here, Feder attempts to support a doctrine similar to Manifest Destiny. The nation is what it is because of the belief in God. Well, how about those nations that believed in God, and where doomed to failure? What about those people, such as Armenians, God Fearing Christians, who were brutally massacred by Turks? Where was this God that supposedly blessed so much upon the
Alexis de Tocqueville observed that the genius of our infant republic lay not in its farms and workshops but in its churches whose "pulpits flame with righteousness."
How does this quote provide legitimacy to the religious point of view? Just because one digs enough and finds a quote to support their view by a person of fame in history does not make that quote absolute. I'm sure many quoted Hitler before his true brutal nature was realized or currently quote Machiavelli who's doctrine was to effectively and violently suppress individual liberties (this from a Christian). Further, billions thought the world was flat, but you don't hear quotes from many of the Popes and religious figures who believed the Earth was the center of the universe quoted in that context. The issue with Tocqueville is that he may have provided the infant American republic with some legitimacy but if he knew what we know today, would he have quoted the same? This was at least 200 years before the proper application of the scientific method (When it was in its infancy). Moreover, how would all of those famous dissenters against progress and supporters of religion view the world with the knowledge, education, and framework that modern science provides?
Atheists are free to disbelieve and to try to propagate their disbelief in books and other intellectual forums. But saying the debate is over doesn't make it so. A bit of humility might make their case more convincing. Then again, humility is itself a religious concept.
Again, Feder attributes human characteristics as the domain of Religion. Humility does not need a religious explanation. Humility can come from realizing one's insignificance in the vast expanse of the universe, and at the same time, elevating the significance that human beings and the planet Earth has on us as individuals. Where is the humility from the religious point of view? In Feder’s case, believing that Judeo-Christianity is the one true path, while others, although carrying positive messages, cannot compare to the splendor of his archaic dogma? Isn't this arrogance? Questioning everything and not taking anything for granted come closer to humility then an unalterable believe in a system that is not well understood. Granted, Feder may believe he hears God, sees God in everything, just as a Buddhist may feel one with the Buddha, but this does not make either's point of view any more valid.
Don Feder is a former syndicated columnist and author of Who's Afraid of the Religious Right?
Having thoroughly destroyed the weak philosophical arguments and tactics that Feder uses to establish his point of view, a new paradigm must be exapted to explain the nature of the universe without necessarily incorporating faith (especially concrete, organized faith like the one Feder attempts to defend).
In terms of probability, any number of faiths have a greater then zero probability that they have some aspect of the universe correctly interpreted. This does not mean that having a non-zero probability, which is infinitesimally small, will be the defining view. There are many mysteries to the universe to be explained, and more questions then there will ever be answers. We, through evolutionary processes, have evolved brains that act on reason, beyond just blind instinct. We are able to ask questions of our environment, create tests to validate them, and subsequently attempt to discern our place in the universe. In other words, we RATIONALIZE the world around us, and a natural byproduct of that is to explain things we don't understand as religious guise. Before we understood evolution, there had to be a reason why there were so many different species (because God wanted it that way). Before modern Cosmology, there had to be a reason why the Earth was in the center of the universe (because we're special in God's eyes -- so much for humility). As science and technology progressed, we were able to reduce the effect that religion had over our daily lives. Comets did not foretell disaster, the Earth is not the center of the universe, all creatures on Earth are linked through a common ancestor, the actual age of the planet is 4.6 billion years, and it is possible to reach the heavens. Furthermore, we now realize that diseases are not caused by evil, or other people's influence, or the devil, but by microscopic organisms, or pathological changes, or metabolic dysfunction, or any number of concepts only recently (within the last few hundred years) discovered.
One major problem with Feder's Arguments would be the complication should extra-terrestrial intelligent life every be discovered. In fact, even the discovery of microscopic non-sentient organisms would shift the paradigm to more rational thought. How would Feder's myopic and arrogant view that his faith is the truest be retained, when a civilization outside of Earth is discovered. The Bible never mentions extra-terrestrial environments. If God was truly behind the Bible, then where is the mention of the true nature of the universe? Where are the planetary surfaces, or galactic super clusters, or even just the Earth's core? There is little, if no real science in the Bible, and should there have existed a creator that would have created the universe as we know it, then he most necessarily could have found a way to explain some of it. Feder, like others, will take these examples as tests of faith. Maybe, in their thinking, God is tricking us into believing that the universe exists as it does, when in fact it's all a ruse. Well, I'm sure that's good and well for him, but it doesn't work for rational thought. Further, even with such views, he will continue to take medication provided him from the benefits of ingenuity, and science. He will continue to drive cars that could not have been made possible with just sitting around and absorbing faith. Of course, for every argument I pose, he will have a counterargument regarding God's absolute authority. He will say that God gave us brains to create such masterpieces of technology. Well, if God gave us brains for that, then we can also alter DNA sequences, and through genetic engineering, create life forms that would never have naturally existed. This, for people like Feder, would be crossing the line. Yet, where does he draw the line? Perhaps certain forms of genetic engineering will benefit mankind, perhaps cloning will? His views are not based on rational thought, and all is needed, is the exaptation of God into the argument. Well, if his understanding of the Universe was greater, perhaps his need for summoning this mythical being that exists in the heavens directing his and all our lives, would not be as forthcoming.

The need for Vigilance in Science
In science, contrary to popular thinking, many hypotheses are incorrect. In fact, considering all the published papers, most of the ideas presented will eventually turn out to be substantially false. The importance of these ideas, even those that will become false, comes from the rigorous testing methods that can prove the veracity or errors present in the initial hypothesis. As a tool, the scientific method can become useful in assessing the likelihood that a given theory can be upheld with incoming data. Science therefore, must be supported through experimental means, beyond theoretical assumptions. The tools at our disposal, are far numerous to count. As an example, computer simulation can be a powerful determinant when it comes to proving certain hypothetical claims. Further, numerous analytical techniques can correlate data into a comprehensive understanding. When considering evolutionary theory, Natural Selection remains supported through hundreds of different methods present at a scientist's disposal. Through molecular genetics, radio-isotopic analysis, taxonomy, paleontology, comparative anatomy, and numerous other converging fields, the Theory of Evolution through Natural Selection is not only supported, but strengthened and refined. With the development of newer tools and even more specialized techniques, specific details can emerge and add to the mountain of data already present.
Having been exposed to the thrills and rigor of evolutionary theory, it's striking that as comfortable as one becomes with a given subject, the likelihood for a breach in upholding the standards practiced at first, increase rather substantially. Since the field of evolution is so vast, theories abound in a seemingly chaotic fashion. Some remain conserved from the moment of inception, and others are as likely to change as autumn leaves in temperate locales. It seems as though some theories are presented just to strengthen the opposing argument while others are just like small stepping stones, aiding to an all encompassing bigger picture. With so much mercurial transition, the danger of complacency increases in a staggering manner. Certain theories seem logical, and therefore, so intuitive that they are grasped as though they were proven with little doubt. These are "fashionable" ideas that can vary from replicable and probable, to absolutely impossible. An example is the radiation of mammals during the Cretatious/Tertiary era (approximately 80 million years to about 40 million years ago). It was long assumed that before the extinction of dinosaurs as well as 75% of other organisms on Earth, mammals were simple, shrew sized animals living nocturnally and barely scraping through an existence. Further, it was only after the K/T (65 Million years ago, otherwise known as the end of the Dinosaur Age) extinction event that mammals had the freedom to radiate and fill various ecological niches. As intuitive as this theory may seem, it has recently been proven largely false. As it turns out, through molecular analysis (of various mammalian DNA), it turns out that most modern mammals had 2 major radiation events where they evolved into numerous species. The first was well within the Dinosaur age, at about 80 million years ago, while the second event was well after the extinction event, dating to approximately 55 million years ago. Those mammals that did radiate directly after the K/T extinction were eventual evolutionary dead ends. They have left no known modern ancestors. The Mammals that exist on Earth today are a result of the aforementioned radiation events, and not the latter that lead to the post-extinction radiation. With the molecular data pointing to these two dates, the challenge now falls upon the paleontologists to match the fossil record with that of the molecular evidence. What this new finding means is that although early mammals were indeed the size of shrews, they were genetically very diverse. They went through two periods of explosive diversity, followed by slower evolutionary changes. Although this new data increases our understanding as per the dates of the events, theories as to why these occurred when they did are now being published. What lead to these two periods of radiation? Was it subtle changes in the Earth's climate? The configuration of the continents? The diversity of flowering plants, or insects, or items that were consumed by mammals?
Having spoken of the dinosaur age, certain assumptions of fossilizations must also be disassembled. It was long thought that fossils could not preserve any genetic material for tracing. Until recently, most paleontologists expected fossils older then 50,000 years to have very little chance of preserving any observable material. They assumed that mineralization of the tissues would be complete, and no actual tissue could be left preserved. Even insects fossilized in amber were thought to mineralize from the chemicals present, and have no usable tissue remaining. The assumption was proven wrong when a paleontologist by the name of Mary Higby Schweitzer of
Having earlier delved through the confusion that abounds in mammalian diversity, other aspects of evolutionary theory are just as difficult to understand. The former example (of mammalian radiation) provided the fallacy of "compound intuition". The next example will shed light on the fallacy of "convergent observation". Certain parallel behaviors that we observe in nature can seem to have a common root. A common fallacy is to assume that perhaps those behaviors share a genetic basis. In fact, what we observe can in fact be due to convergent evolution that uses an optimal survival strategy. It will become apparent that an organism doesn't necessarily need a specific "gene" for useful strategies to perpetuate its survival. For example, just as a tropical fish will flee into a small crevasse in coral to escape a predator, an arctic lemming will dive into a small hole to do the same. Although these two strategies seem similar superficially, the organisms do not share a "flee into a small hole" gene. Their strategies are the optimal best to ensure survival therefore they remain within those organisms. The genetic tools they use to escape are completely different, even though the end result ensures survival. Similarly, genes that control social organization among species can vary greatly. The same optimal survival strategy that dogs use in pack situations, ants use in colonies, and naked mole rats use within their own hierarchy is similar to those of our own species. Organizing into cohesive social units furthers our chances of survival, although the genes that govern this behavior are completely different. Moreover, similar convergence in evolution can be found in the development of the eye. As it turns out, the ancestors of various modern species evolved eyes completely independent of each other. The eyes of the box jelly fish, or the mantis shrimp, are completely different then that of human eyes. Yet, in an organism's development, some genetic sequences that govern the placement of the eyes are very similar (hox genes for example). This similarly however, does not mean that there is a genetic link between the development of the eye in these organisms. What actually happens is that the environment dictates the advantage of a sensory organ for sight, and as certain evolutionary trends evolve, gene sequences are used that are similar between these organisms for the same function. To simplify, if jelly fish and humans both use the "Z" gene for eyesight, it doesn't necessarily mean that they both had a common ancestor that used the "Z" gene for sight. At some early phase of development, the ancestors of jelly fish and humans acquired a certain gene sequence ("Z") that independently resulted in governing the development of the eye in these two organisms. If looked at superficially, it would seem to some that this ancestral organism (Concestor, using a word invented by Richard Dawkins-- one of the most well known evolutionary biologists) had used the "Z" gene for eyesight and then the branch the lead to the jelly fish/human split acquired this characteristic. In reality, the Concestor passed on the gene first, and then some time later, the progenitors that resulted in jelly fish acquired the usage of the gene for eyesight, just as those early organisms that resulted in humans did independently as well. Naturally, this is an oversimplification, because the common ancestor between what later became humans and jelly fish existed over 500 million years ago.
Finally, after Gregor Mendel's legendary experiments with peas and genetics, followed by the discovery of the actual carrier molecule for those genes (DNA), many geneticists felt that soon, genetic inheritance would be completely uncovered. It was assumed that within a few decades after the initial discovery of DNA, all would be known about genetic inheritance. As it turns out, those assumptions could not have been more wrong. As we've come to realize, genetic inheritance isn't as simple as once was thought. The simple assumptions that the interplay between dominant and recessive genes, along with the sexually selected genes determined inheritance. It was also thought that each gene coded for a single protein, but as our understanding of molecular biology and chemistry improves, we now know that things are far more complex than assumed. The same genes can code for various different proteins if they are placed different locations with different activator sequences. Other genes code for nothing but unused DNA. Furthermore, the concept of imprinting greatly compounds our understanding of Mendelian Inheritance. With mammalian imprinting, the male or female parental genes can disable the other partner's and as a result, the offspring will only retain one copy of that gene. In other words, the gene becomes useless because it's function is blocked by one of the parents. Although some traits can easily be explained through Dominant and Recessive genes, other traits are a result of the complex interplay between numerous genes and imprinted genes within an individual. In fact, even environmental changes can determine the expression of certain genes. Not only genes in an existing individual, but the changes in certain sequences can effect individuals many generations down the line. For example, under the newfound field of epigenetics, scientists are realizing that obesity can alter genes in such a way that many generations of descendents can be effected by Diabetes, among other medical ailments. In essence, the processes are so complex, that it could take hundreds of years to decode the workings well.
In essence then, science will always shift in new directions, with additional information arriving. Observation is thus, the most important trait in science, and as we invent new tools to further our observation, and then theorize and explain those observations, our understanding of the universe will continue to grow. As certain theories are invalidated, our understanding strengthens because now we can rule them out. Further, even more questions will arise, as some of those are answered and others discarded. This is ultimately the beauty of science. Errors will always be useful because they help focus our understanding and strengthen or weaken existing theories. Science is therefore alive and will evolve with our progress. As an example, before the car existed, the wheel must have been invented, followed by the cart, carriage, etc. Similarly, incremental steps are so important, that we cannot take them for granted. After all, a ladder can't be climbed by great leaps, but step-by-step (of course, occasionally, you can take two or three steps up the rungs, but you also risk falling, just as is done in science). Thus, most apparent breakthroughs are not enormous leaps but lead to rapid descent followed by yet another surge towards the top. Therefore, with vigilance comes momentum and progress.

The Rifle Shot that Blew my Mind
Having just seen the Oscar winning movie
A causality cascade could be anything that snowballs into something larger. In effect, it's like an uncontrolled chain reaction with no predetermined intention. When an atomic bomb undergoes fission, the neutrons in the atoms start a cascade chain reaction effecting others exponentially until the immense powers of those nuclear reactions are released. In this instance, there is a clear predetermination as to what the subsequent result will be. The neutrons do not undergo uncontrolled chain reactions like the causality cascades, because the end result is a mushroom cloud, and everything must result in precise timing. Causality cascades on the other hand, as already mentioned are not predetermined, and are extremely uncontrollable. Events can effect other events in such ways that could never be imagined, because there are an infinite amount of possible outcomes from each event. Chaos theory attempts to describe these events, whether they involve atoms, computer generated fractals, or even human actions, into a mathematical model that attempts to predict various probabilities on possible outcomes. At the point of infinite variation, it's impossible to predict exactly how an event that is so complex will turn out, yet there are events that can be more likely to occur then others. It's similar to quantum effects* on atoms. It's impossible to predict the exact location of an electron orbiting an atom because measuring and observing the location of the electron forces it to change, and alter its initial state. Therefore, the best one can hope for is to determine a probability of where the electron may be. There is a chance that the electron itself can be found at the other end of the universe, and with trillions of electrons, it's very likely that one may end up there through some complex quantum effects. Yet, through probabilities, the electrons are more likely to be found in certain regional distributions, and the greatest amount will be found in certain areas orbiting atoms. Taking this in mind, it's possible through causality cascades to have a butterfly flapping its wing in
Our actions on a daily basis will therefore, inevitably lead to an infinite number of causality cascades, some which we consider good, and others which we consider bad. For example, perhaps giving the right of way to a driver waiting on a busy free-way onramp, will result in that driver's awareness of others, and through due course and time, this will cascade into good will spread upon numerous individuals, perhaps cascading into someone's life being saved. In the same token, it's also possible that cutting somebody off, will result in the driver's behavior to become erratic, and through numerous other chain reactions, one of the angry drivers along the way will do something rash enough to cause an accident and involuntarily take a life. Finally, a third possibility is that what one perceives as a positive event can become negative to others. For example, taking the same driving scenario mentioned, perhaps suddenly breaking to avoid large debris on the freeway may be beneficial to the individual driver, and the avoidance a positive event, yet, the reaction may cause more disastrous results to drivers following behind. It may be a positive event to one life, but its negative impact may be felt by dozens of others following behind. In another example, if a small child was choking on food particles, and one were to assist in saving the child's life, it would definitely seem like a positive event. However, what if this child in turn became a Tyrannical leader who's path of destruction lead to the death of millions, wars of aggression and perpetual hostility? Then what seemed like a good deed, could in fact have been a great disservice. If one knew ahead to time, that said child would turn out to be Hitler, the morality of the situation would definitely be difficult to assess. These scenarios show the complexity of causality cascades, and how their effects cannot be trivialized or minimized. There is no way to avoid effecting events along the chain when one has no predetermined notion as to what will follow. Yet, there are scenarios high in probability that are more likely to occur when one analyzes the events thoroughly and attempts to discern some form of causality.
Having defined and explained causality cascades, one need look no further then those individuals in prominent positions of government to realize just how much power they have over events that effect every individual's life. The causality cascades that you or I are able to initiate in our lives are infinitesimally small, compared to those that Bush, as well as other "leaders" are capable of. Bush's decision to launch an aggressive war on Iraq leads to the destruction of an infinite amount of lives, over such flimsy reasons as weapons of mass destructions. When the excuse for invasion failed to materialize, other excuses such as freeing the Iraqi people, or spreading democracy in the region were provided. Ultimately however, countless lives have been directly changed on account of specific actions taken without much consideration to possible outcomes of events. The civilian lives that have been taken in Iraq as a direct result of these actions, along with the billions of lives in the world that have changed, are the result of one man's determined and faulty mind. When we elect those who are supposed to represent the people, we rarely consider just how much power we are providing them. These people shape the future of the world. Going back to Bush's example, not only did his invasion cost over 3200 American soldier's lives, it also cost over 100,000 Iraqi civilian lives, and indirectly, the infinite lives of those who would have been born had their predecessors not have been killed. Perhaps one of those soldiers would have fathered (or mothered) a child who would have discovered the cure for AIDS. All of these potential human beings will never exist because their parents were killed as a result of a few poor decisions. What would the world have been like if Gandhi's father was killed by the British? Or how different would civil rights in the United States have been had Martin Luther King's mother been lynched? What if Philip of Macedon, Alexander the Great's Father, been killed in an intradynastic feud? All of these questions become obvious when we realize that each person has the potential to influence countless other lives, either positively or negatively. Most of us influence lives completely oblivious to the chain of events that unfold, but other's have so much power, that their decisions determine the course of human history a thousand fold as compared to ours. Although we are all able to determine the course of history because just being alive and interacting with the world changes the causality of the situation, the scale at which we do it can differ. Those who hold the reigns of authority have the power at larger scales then others. We are enabling them to determine the fate of the world, and are oblivious to the nature of their capabilities.
Ultimately, causality cascades can be found in the same uncertain philosophical grounds as notions of morality such as good and bad. Attempting to define causality cascades as good, and other's as bad can seem like a moot point, considering our ignorance at the ultimate effects our actions may take. However, just being aware of the profound multilayered interactions of our lives can be illuminating in itself. Knowing that defining such events as good and bad can become a lesson in futility, the act of defining cannot be completely dismissed when taken in an attempt at furthering our thinking. The traits that have allowed human beings to transcend simple instinctual urges, and have allowed us to pause and reflect, are thus furthered with the knowledge and questions that we ask about our nature. Causality cascades are an important aspect of self definition and growth because we have the heightened senses to be capable of the awareness of our actions and the possible consequences they may entail. Yet, just because the potential exists for such deep introspection, the application of it is based on an individual basis. Most of us have the tools to further our understanding of the universe and ourselves, but because of various barriers and filters (Such as certain religious beliefs, cultural nuances, social standing, and serendipity of living comfortable enough lives to be so introspective), many are not able to exercise such potential. The most unfortunate side effect of this wealth of potential, is that those who should be required to tap these tools within us live their lives thirsting for material gains, power control and petty squabbles that don't matter much to the greater world. By this, I mean the elected "representatives" of the world. How long will we allow these bickering, selfish, self absorbed, narcisstic, and ineffective individuals ruin our futures before we stand up and fight? We are lead to believe that the most important things in life are acquisition of wealth, and superficial trappings of civilization, when in fact, we're ignorant of the greater good that society can offer. We are so entrenched in our immediate lives, that we're ignorant of the greater potential for humanity. We watch news to uncover updates on Anna Nicole Smith and Paris Hilton, when in fact, we should be concerned about the advancement of our species and the survival of our planet. In the end, the future of the world will rest with how we define ourselves, and come to understand the consequences of our actions upon the planet. Just like a butterflies wings, small effects can have enormous unintended consequences. We are all small effects, but we're not inconsequential. After all, causality cascades cannot rule out the potential for even one human being (further reducing that idea, such cascades cannot even rule out the behavior of an atom, but with human beings, our actions can be consciously analyzed, and reflected upon).
