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 .
