Darwin understood that organisms are variable, but for a long time he lacked a mechanism, or a driving force, of evolution. Natural selection, or a complex natural process of elimination, turned out to be one of Darwin’s most ingenious contributions to evolutionary thought (Mayr, 2001). Natural selection is the process by which genetic variation is sorted through and selected for through the organism’s ability to survive. Selection may be due to environmental conditions, competition with other species, or reproductive success. Those organisms that survive can then go on to reproduce, and their offspring then carry the successful traits.
Darwin’s concept on humanity initially begins with evolution. In order for the cogs in the wheel of nature to turn, there must be significant differences within species. Darwin refers to this idea as variation, which can be found within the aesthetic, behavior, or genetic makeup of an individual found in a species. These variations generate competition within species to survive, seeing as there will ultimately be both favorable and unfavorable traits. The concept of survival of the fittest is notably known as Darwin’s natural selection theory.
The Evolution of Anthropocentrism Evolutionary theory throws humans into a tizzy. Driven by the need to amass knowledge, we find ourselves surging forward into the exploration of a story where the more we know, the less we can feature ourselves. Eminent evolutionary biologist Ernst Mayr contends that anthropocentrism and belief in evolution by natural selection are mutually exclusive (Mayr 1972). In other words, the Darwinian story of biological evolution rejects the notion of progress and replaces it with directionless change, thereby subverting the conception of human superiority on a biological scale toward perfection. Evolution by natural selection undermines the idea that humans are the culmination and ultimate beneficiaries of all nature.
Charles Darwin, the “Father of Evolution,” inadvertently laid the foundations not only for life and science as it is known today but also for the concept of human nature and questions of its potential framework. After Darwin’s discoveries, many other researchers lay claim to the role of genes and heritability in nature. Some researchers assert this role of genetics in human nature, labeling it as a necessity in the development of a complete understanding, whereas other researchers deny genetics’ role in human nature entirely, claiming it to be a hindrance for scientific and social advancements. However, the novel Life of Pi by Yann Martel and the play Copenhagen by Michael Frayn show that human nature may be based not only on genetics but also on external factors. But what are the true differences, if any, between the impact of genetics and the impact of culture on the human being?
He adopted an approach that focused on the level of the gene. He saw social behavior as controlled, in principle, by particular genes, and he saw evolution as occurring at this level because reproductive success amounted to increasing the frequency of certain genes in future generations. However, the insistence of sociobiologists on grounding at least some behavior in universal human genetic predisposition runs contrary to cultural anthropologists' emphasis on the primacy of culture itself as the determinant of human social life. Several distinct approaches can be identified in contemporary sociobiology. The first one is evolutionary psychology.

Scientists are able to clone, help create life amongst other things that one-day were considered to be so far fetch and probably never thought to be possible. One thing that science cannot answer until this day is how life begun on earth. There are several theories offered some more accepted than others, but nothing is set on stone as the clear explanation. Research like this one does not attempt to answer this question as well, but it does help to fill in the loopholes in the history of human creation if our thinking process follows the orientation of evolution.
Since Darwin first proposed the theory of evolution with the publication of The Origin of Species by Means of Natural Selection, in 1859, the debate between creationists and evolutionists has been vehement. Both creationists and evolutionists believe the evidence supports their theory and denies the other. Scientific creationists see evolution as a completely unscientific theory supported by insufficient evidence. They believe that much of the evidence used to support evolution actually supports creation. On the other hand, through studies of comparative embryology, the fossil record, and comparative anatomy, evolutionists have found evidence that both directly and indirectly support the theory of evolution.
So evolution over a very long period of time can result in the development of new variations and species. Creationists believe that in the concept and design of living organism, a creator is needed. Creationists think that organism can adapt to their environment, but do not change so that over time they become a completely different organism then what they were created as. Evolution is the only reasonable theory of them two considering what evidence has been found. This essay will explain in a chronological structure why, by exanimate four major creation arguments, the creation theory is not as reasonable as the evolution theory, based on evidence.
Evolution is still a theory, this simply means that this has not yet been confirmed. The reason for this is because there is still some evidence that mismatches when it comes to evolution, some examples may be the complexity of the eye, living fossils, dating methods and microevolution/macroevolution. There is a process known as Microevolution which is actually happening. Microevolution is real, it is the small changes within many different species occurring in their genetic code and happens in a short period of time. Macroevolution is the process in which a new species is formed from genetic information which previously did not exist similar to how apes transitioned into humans when they did not exist.
Their scenario has also evolved through iterations of accumulating, adapting, and eliminating ideas according to new findings, new observations, and new knowledge. In the process, the narrative's woof and warp have tightened. Gaps narrowed to the point that, in "What Evolution Is," biologist Ernst Mayr could proclaim, "Evolution is not merely an idea, a theory, or a concept, but is the name of a process in nature, the occurrence of which can be documented by mountains of evidence that nobody has been able to refute...It is now actually misleading to refer to evolution as a theory, considering the massive evidence that has been discovered over the last 140 years documenting its existence. Evolution is no longer a theory, it is simply a fact" [Mayr 275]. Central to this "simple fact" is the concept of speciation, which was developed in the 1930s by Dobzhansky and Mayr.
