    On the Origin of Evolutionary Thought: By Means of Science

    More often than not, human beings tend to have an aversion to ideas that make

    them feel insecure about their destinies, or lack thereof . With the phenomenon of

    consciousness comes the eternal struggle to find one’s place in the universe, and naturally

    it is one of the most difficult concepts to confront. Throughout most of human history,

    religion has been an asylum for minds aching to find this kind of comfort in the cosmos,

    and schools of thought that try to provide explanations of our origins have to fight to have

    their voices heard. A general trend throughout the centuries is the sphere of influence of

    religion shrinking to make room for scientific enlightenment; as we gather more and

    more information about the workings of the universe, we have less of a need to explain

    things away with simple answers, such as “God made it happen.” In his book Monkey

    Trials & Gorilla Sermons, Peter J. Bowler shows this exact pattern of societal response to

    ideas that take humans off of a divine pedestal, specifically evolution by natural

    selection, and brings to light the extent to which humans will go to preserve their fragile

    egos. 

    The biblical account of human origins as put forth by the Book of Genesis is a

     pretty rigid explanation for how we came to be: God created Adam in his image, then

    formed Eve, and expelled both of them from the Garden of Eden for disobeying his

    instructions to not eat fruit from the Tree of Knowledge. Their offspring, and their

    offspring’s’ offspring, then went on to populate the world, and we are all descended from

    that original line. This story of Creation gives humans the sole position out of all other

    life forms to have been formed in God’s image, and therefore grants us a special place in

    his eyes. One can immediately learn from this story that humans like to think of

    themselves to be of a higher order than other organisms. As we explore the history of the

    theory of evolution in more detail, we will see that this attitude carries on to this day, and

    it is one of the main arguments that is used to justify the rejection of evidence that shows

    us otherwise. 

    Darwin’s On the Origins of Species: By Means of Natural Selection is one of the

    great milestones of science, and it incited a firestorm of criticism unlike any other major

    scientific revolution. The reason for the polarizing response is that it was the one of the

     biggest infringements of science on the intellectual property long held by the church. 

    Before Charles Darwin came along, one could not easily propose a plausible explanation

    of the origin of man that wasn’t the one put forth by the Bible. While studying the

    adaptations of different species of finches on the Galapagos islands, Darwin realized that

    the traditional Creationist viewpoint would imply that “God had performed a separate

    miracle for every finch and mockingbird species on each of these insignificant islands”,

    and that “this position reduced the creation hypothesis to absurdity” (87). It seems

    apparent that the biblical creation story does not stand too resolute in the face of the

    overwhelming diversity of life, and Darwin realized this even without the extensive

    knowledge on the subject that we have today. His book brought up legitimate questions

    about the validity of the biblical account, and sparked some serious debate about whether

    his scientific findings were reconcilable with Genesis. When analyzing the arguments put

    forth by early opponents of evolution by natural selection, we see that one of their points

    of contention was the implied relation between humans and apes. Apes, such as gorillas

    and chimpanzees, were seen as dirty and brutish creatures from primitive and uncivilized

    regions of the world, and the suggestion that they are our closest animal kin was

    considered ridiculous. The reaction to this idea is one of the more obvious examples of

    fragile human egos getting wounded, and efforts to suppress notions like these showed

    how desperately people wanted to believe that God created them separately from other

    animals. In the famous Huxley vs. Wilberforce debate at Oxford, legend states that the

    religious Wilberforce asked Huxley if he was descended from an ape on his grandfather’s

    side or his grandmother’s side. This point was made as an effort to ridicule this notion of

    common descent, and it really underlines the efforts made by creationists to preserve their

    status as higher life forms. As early as the 1870s, Darwinism was accepted by most

    scientists and even most religious thinkers. However, some schools of thought, such as

    the Lamarckian theory, were starting to gain some ground as alternatives to strict

    Darwinian evolution.

    One major source of disagreement was the role of natural selection in the

    evolutionary process. The very nature of natural selection is a random and unforgiving

    one; it is based on the selfish and individualistic struggle for survival, and it allows entire

     populations to go extinct. How could a benevolent and compassionate creator allow so

    much suffering and needless death to happen in the world in such a seemingly mindless

    manner? By implying that humans are merely by products of billions of years of

    evolution, proponents of evolution via natural selection were apparently advocating for

    humans to be viewed as nothing more than apes that could build cities. The idea of small

    and random variations that eventually diffuse through a population was clearly the

    opposite of that of a divine creator who had a plan for every human ever born. It was not

    only creationists who were opposed to natural selection, but also evolutionary scientists

    who did not want to believe in the random nature of natural selection. Lamarckian

    scientists believed in the gradual evolution of species, but through an alternate process

    called the inheritance of acquired characteristics. These scientists believed that this

     process was driven by a universal moral purpose: progression towards higher forms of

    life. This took place before the development of genetics as a legitimate scientific field, so

    they thought animals could inherit learned characteristics from their parents (such as

    giraffes passing down the trait of long necks to their offspring by stretching their necks a

    little bit further to reach high branches). Lamarckism allowed for evolution to occur, but

    it allowed organisms to “control not only their own destinies, but also the future

    evolution of their species” (138).  It is evident that the Lamarckian movement stemmed

    from peoples’ desire to have some sort of order and meaning to their lives, as opposed to

    more unpleasant notion that we are here due to the extreme luck of our ancestors and the

    misfortune of billions of other animals in the past. It is a completely natural and sane

    reaction to be immediately turned off from the idea of natural selection, especially if one

    is already predisposed to the idea of a “meaning to life”. Reducing one’s own existence

    to something as selfish, random, and unforgiving as natural selection is almost

    counterintuitive to the idea of placing value in all living things, and it can be a depressing

    thing for a lot of people. For most Lamarckians, it was the inherent “lack of purpose”

     behind natural selection that turned them away, not the science behind it. It was hard for

    them to accept that evolution was driven by struggle, rather than some more positive

    force. They wanted to believe that early giraffes “effectively marked out the whole future

    of their species” by reaching their necks out to grab leaves, instead of the natural

    selection viewpoint that the giraffes that couldn’t reach the higher leaves died out

     because they could not compete for resources. This desire to find a purpose behind the

    evolution of species stemmed from their desire to find a purpose to their own lives,

     because they could not accept that we are just another ordinary species of animals,

    instead of a part of some upper echelon of evolved organisms. In the case of

    Lamarckism, it wasn’t solely religious people who were trying to discredit natural

    selection, but the concept of humans having a special place in the world originates from

    religious teachings.

    While adherents to Lamarckism were not saying humans were created 6,000 years

    ago like the biblical literalists, their hopes for a positive and meaningful evolutionary

    driving force had roots in the creationists’ beliefs of some sort of purpose built into the

    fabric of the universe. It wasn’t until the 1920s and 1930s that major advances in genetics

    and statistical analysis of populations began to show the scientific community that natural

    selection, and not some cosmic moral force, was in reality the main explanation for the

    diversity of life. The modern evolutionary synthesis combines findings from a wide range

    of fields, such as evolutionary biology, paleontology, genetics, developmental biology,

    etc, to formulate a rigid theory of evolution. Once scientists were able to find and analyze

    this kind of data that was previously unavailable, it became apparent that, in the words of

    legendary evolutionary biologist Theodosius Dobzhansky, “nothing in biology makes

    sense except in the light of evolution.” Modern evolutionary theory can be used to

    explain almost the entire spectrum of biological ideas and trends, from the microscopic

    scale of genes to the studies of vast populations. After decades of extensive research,

    debates, and publications, the scientific community came to accept the ideas of an

    English naturalist with uncanny intuition, despite the protests of numerous wishful

    thinkers.

    The theory of evolution by natural selection has had a very rocky past, as it was

    assailed from all directions for being to impersonal and harsh in its implied worldview. 

    The majority of arguments that it faces come from people’s desires to preserve their place

    in some sort of plan for the cosmos, and in the process, save their egos from crashing

    down to a more grounded worldview. We can see this even in religious movements

    today, such as young earth creationism, which outright reject all scientific evidence that

     point towards an impartial and sometimes “unfair” universe. This very natural reaction to

    devalue uncomfortable ideas is what has held humanity back from reaching its full

     potential for progress for centuries, and will continue to persist if we do not accept that

    we are, in fact, not special and merely byproducts of indifferent natural processes .
