Charles Darwin Evolutionary Theory - Essay Example

Evolution is a process which has been happening, since time immemorial. Individuals in the past tried coming up with assorted meanings to describe the process of evolution, but few succeed in this endeavour. Naturalist invented various hypotheses describing the origin and course of evolution. Among the naturalist were Aristotle, Anaximander and Empedocles. They came up with contradicting theories regarding how evolution was in existence. One train of thought by researchers states that evolution is a process that involves a change in inheritable traits.

Evolution involves diversification of the gene structure from the parents to the offspring. The evolution concept is influenced by several factors leading to changes in the gene composition of a living life form. The factors are a mutation, sex gene and the usual selection (Mayr, 83). This refers to a change in the configuration of agene. The change in the structure of the gene is permanent and can not be modified. The change is due to the alteration of the structure of the amino acids present in the gene.

Sex gene refers to the genes that are responsible for the sexual attributes of an organism. The sex genes contain the chromosomes that are responsible for the transition with each other leading to the development of new life forms or species. Natural selection refers to the gradual process of composition of biological traits to one side of the gene molecule. Natural selection brings about the observable characteristic noticeable in an organism. The gradual composition of a trait is brought about by the connections of the genome and the surroundings of a living life form.
