Evolution can generally be described as directional change. However, biologically, evolution it can be defined as modification form a single ancestor or ancestral population. It is also a characteristic common in a population and not in a single individual. Subsequently for a change to be evolutionary, it must affect genes passed on to the next generation. Evolution is related to culture in that, though human behavior is totally learned, it rests on biological base. Theory of Natural Selection The theory by Darwin was based on simple observable traits among members that are easily observable and hard to refute. In this view, therefore, due to the simple set of ideas, the theory is both powerful and elegant. Darwin`s approach to this theory was through observation on nature that no two living things are alike even those of the same species. He further discovered that all organisms are subject to mutation, which is a random change in genetics. Reproduction creates genetic flow as a result of mixing the genetic material creating new variations.…show more content…
However, others survived and Darwin observed that they did so, not through random occurrence but for some reason. Darwin described his theory as “survival for the fittest”. Fittest to mean that only those organisms that were best adapted to their environment did reproduce. In that, organisms best suited for their environment succeed in the struggle for food, and pass on the traits while those les suited just disappear. Punctuated equilibrium model of 1972 by Eldridge and Stephen Gould supports Darwinian Theory of evolution as a slow, steady and continuous process. Consequently, the model suggests that organisms remain stable only for a period before they rapidly change due to natural selection and genetic
