Confessions of a Closet Darwinist
I regret never to have religiously studied the rudiments of biology in high school. It could have been a lot easier to understand what I have been reading and digesting all these years. As I dabbled with philosophy, studied esoteric ideas of great men who left a significant mark in the annals of history, strangely it was in the arena of science, biology in particular, that I came to know my newest hero. His name is Charles Darwin, the influential English naturalist who wrote this gigantic book, The Origin of Species.
Beyond the notion of frog-hunting, it was in my high school biology class when I first heard the name Charles Darwin. Back then, I pictured him merely as one of those typical textbook scientists famous for some weird scientific ideas and discoveries of his day. When I first heard my biology class teacher explaining in general how evolution by natural selection works, I was surprisingly in awe of its beauty and elegance. Just imagine how simple life forms could develop over long periods of time into increasingly complex creatures that we see today and you’ll get the entire picture. Maybe Darwin was right after all, at least scientifically. Evolution by natural selection seemed to be the most plausible natural process to explain why there are vast array of plants and animals on our planet. Given sufficient time with life-permitting conditions in our environment, who knows what the natural outcome might be, right? Anything seems possible. Nothing is static. Everything is susceptible to change. When we observe things around us that appear to be purposeless, or when we bellowed at the freaks of nature featured in the Discovery Chanel, the theory of evolution seem to fit perfectly in the grand scheme of the natural world.
Initially, my unscientific mind was willing to accept Darwin’s theory of evolution. Not until, Darwin went further and introduced the idea that you and me share a common ancestor with apes. I was appalled by his claim. I felt disgusted to know that I’m just another animal species roaming this part of the jungle. Wandering around, preying on others. I know then that as a teenager I exhibited some kind of animalistic tendencies, especially towards the opposite sex. Touché! But who would have thought that science has a different view. A view that would make this supposed impish behaviour perfectly natural and normal. True enough, my ignorance in the realm of science made me wonder if Darwin could have been insane or something when he introduced this ludicrous idea that human beings came from the same common ancestor as the apes. If at all he was sane I said to myself, Darwin was simply guessing or playing hunches on this one. After all, the theory of evolution by natural selection is just a theory. And just like any other scientific theory floating around, the theory of evolution can never be accepted as a fact unless backed up by provable and well-reasoned explanation.
Growing up as a nominal Christian
I was raised in an Evangelical household, one where you had to be in articulo mortis to skip Sunday service or family devotions. Obviously, I learned to read at a very young age because our shelves were stacked with Christian literature, mostly bible story books for kids. The “Creation Week” in the Book of Genesis had to be one of my favorite bible stories. I was certain that I understood the Bible correctly: God created all living creatures, including human beings, in their present form during the six-day period known as “Creation Week.” The Bible did not say that these creatures, like the animal species have evolved over long periods of time, from less advanced life forms to complex ones. God created dogs as dogs, cats as cats no more no less! I could not imagine, not even in my wildest dreams that human beings are not special creations from a supernatural being whom we call God. The Darwinist view that human beings could have merely descended from the same common ancestor as the apes is simply preposterous. We are special creations. Human beings are created with a purpose. Despite my rudimentary knowledge on biology, I concluded that science limps as it walks on the issue of origin. No one, not even Charles Darwin and his ilk, could ever explain how it all began in the first place.
At the back of my mind however, something bothered me tremendously with what Charles Darwin is saying. My sudden three-hundred-sixty degree turnaround could hardly be considered intellectually-based or anything. I guess even if someone could present me with rock-solid evidence to support evolution, still I would suspend my judgment at that time. I would remain adamant and will refuse to accept it as a fact. I would go even further and label it as the work of the devil. I was fearful of Darwin’s theory because of its simple yet striking implication on the meaning of life. Although not a boxing enthusiast, I can tell that Darwin had just delivered a one-knockout punch, the heaviest blow unleashed against what I perceived to be an untouchable opponent. Looking back, my dismissive attitude was perhaps a smokescreen designed to conceal whatever reservations and doubts I had concerning one of the central dogmas of my faith─ the biblical story of creation. Ultimately my puerile mentality has something to do with the kind of intellectual laziness that most Christians are endowed: I know the Bible is true because it’s the Bible!
It doesn’t take a rocket scientist or a theologian to grasp why the theory of natural selection would be so controversial. From the time Charles Darwin published On the Origin of Species in 1859 to this day, the debate continues. The once already volatile relationship between science and religion became more intense and defined with the theory of origin of species out in public. If new creatures are created by natural process, what is left for God, the creator of the universe? If evolution is true, then the biblical account in Genesis that human beings have descended from Adam and Eve is false.
Evolution and the Creation story
What is evolution anyway? Let me begin by saying that Charles Darwin did not invent evolution, he merely noticed it. In simplest terms, evolution is defined as the gradual accumulation of functional adaptations. In order for evolution to work successfully, three essentials are needed (1) time (2) genetic variety among offspring and (3) a mechanism for preserving only beneficial variation. Thus, from a simple life form, an organism can develop into a complex creature. Evolution basically posits that organisms change through time. Then it proceeds through the branching of common descent. Given enough time, changes within a species can accumulate into large changes that create new species or an increasing number of new species. The primary mechanism of evolution is of course Natural Selection. If natural selection is the process from which organisms are indebted for survival or extinction, what place then for a Designer? We must understand that natural selection is not a force but a description of a process. It shows us how the process works. There is no intelligent force behind the “selection” of organisms, there are no conscious choices involved in the process. In order to survive and reproduce in a given environment, one must have the right qualities (adaptations) superior than those of other species in the animal kingdom. Mammals like us are not here by chance. Neither are we here by random selection. We are what we are because we are naturally selected to live and experience life to the fullest.
In the spirit of fairness, let us not single out one interpretation. It would be unfair to discredit the Book of Genesis by selective observation; the good book after all deserves a fair treatment in the marketplace of ideas. How about if we shun from the literal reading of the creation story, what would be the alternative? Perhaps because the evolutionary theory is widely accepted in the science community as fact, religious-minded individuals tend to be more liberal these days. In the Christian community as well as in the academic circles, a group of respected Evangelical intellectuals emerge as the vanguards of modern Christian thinking. This group is popularly known as the Intelligent Design Movement (ID for brevity). ID advocates believe that not every word of the Bible is literally true. Ergo, while the miracles of Jesus Christ in the New Testament are to be interpreted literally, the Book of Genesis should be understood in its metaphorical sense. So in a way if the literalists distort science to reconcile with Genesis, ID on the other hand distorts Genesis to make it harmonize with modern science. To some extent, ID accepts evolution to be true in so far as variations within plants and animals are concerned. Or when a strain of bacteria acquires immunity from antibiotic or rats acquire immunity to a particular type of poison, ID theorist concede that evolution is a fact. But as we know Darwin did not stop there. He goes hundred miles further by claiming that life began millions of years ago with simple cell creatures. And through mutation and natural selection, these simple cell organisms developed into complex creatures we see around today, including us. While ID advocates undeniably agree that micro-scale evolution has factual and scientific underpinnings, they disagree on one significant detail that could possibly account for life’s complexity. Quite similar to the argument raised by theologian William Paley more than centuries ago, ID intellectuals believe that some adaptations are too complex that could not have come about gradually through natural selection (e.g. the cellular evolution).
Michael Behe, one of the leading progenitors of ID, took the challenge and published the critically-acclaimed book Darwin’s Black Box. In response to Darwin’s challenge, Behe offered recent biochemical discoveries that would show that Darwin was partially wrong with his theory. A case in point is the Cell. A cell, according to ID theorists, appears to be “irreducibly complex” in its structure which could not have been the result of Darwinian natural selection. I’m not a scientist but here’s how Behe’s argument works. Let us suppose that a cell has four parts and removal of any one of them will cause the cell to die. Now since all parts is indispensable to the operation of the cell no one of them could have come about in gradual stages until the other four were in place. Thus, the cell could not have evolved at all because the appearance of that cell requires that all four parts to be gradually evolving before the cell could work. From there, ID theorists felt that they have just debunked Darwin’s theory of evolution. However, after all the efforts to come up with a plausible scientific explanation on Nature’s complexity, ID intellectuals bolted out from the scientific world and preferred to take the supernatural route. Since there are no available scientific explanation to account for these “irreducible complex” adaptations, ID theorists assume that an Intelligent Designer might be the answer. Could the Intelligent Designer be the God of the Bible? Because ID presumably operates in the arena of science with a tinge of theology, ID intellectuals are careful enough not to mention the word “God” in any of their books. They insist with all their might that ID is science-based rather than pseudo-scientific.
It could have been an astounding scientific discovery had Behe offered a scientific alternative for Darwinism. Instead ID took a big leap from science all the way to theology, from natural to the supernatural. At this point, Intelligent Design has voluntarily unmasked itself, and exposed what their movement is really all about. Some religious fundamentalist labelled them as a “cult” for butchering settled religious doctrines, secular scientists mocked at them for their pseudo-scientific theories.
W. Dembski. I enjoyed their books a lot because of the intellectual satisfaction I get. Clearly, these ID intellectual giants illuminated my mind on the intersection of science and religion. ID restored my faith that not all religious-minded mammals are dumb. Still I wish Christians should spend more time reading books of the same calibre and throw away all their non-sense praise-the-lord antics in the garbage bin. But despite the smokescreen and euphemisms hidden in the façade of ID, It is my view that the fulcrum from which ID arguments stand is more akin to theology rather than pure modern science. This is problematic because as they go along with their brand of science, ID proponents end up perverting the Book of Genesis and possibly the Bible itself.
Reconciling belief in God and Darwinian Evolution
I accept evolution as much as I believe in God. I subscribe to Darwinism as much as I believe in “Creationism.” If science has proven that human beings descended from a common ancestor as apes then so be it. If science has proven that living organisms are but a product of natural selection sans intervention of the supernatural, then by all means, bring it on! But let me point out one important observation: the theory of evolution does not belie the existence of a Creator. Neither does it say that evolution can explain life’s origin. Whether evolution is true or not, it does not in any way affect my belief that there is a Creator somewhere looking at the universe.
Dr. Francis S. Collins, a Christian scientist and head of the Human Genome Project explicated on the relationship of faith and science: Science’s domain is to explore nature. God’s domain is in the spiritual world, a realm not possible to explore with the tools and language of science. It must be examined with the heart, the mind, and the soul, and the mind must find away to embrace both realms.
We all fear what we do not understand. Most people know little about evolution. Some refuse to talk about it because of its moral implication. Others somehow do not think that evolution would likely affect their lives. Whatever their motives are, let me say that the greatest threat against faith is not science but IGNORANCE. Case closed. Closet opened. Whalah! I am a Darwinist!
