There have been many ideas on the theory of evolution. Some simply take our existence for granted, others prefer to explain all evolution in terms of the bible and the presence of a God. However, there are those who have researched the topic of evolution and have offered an explanation as to where a species comes from and how they evolved in the manner that they did. This type of science has been studied for a very long time, and one of the most famous minds in the field of evolution was a man named Charles Darwin. Darwin was not the first one to offer theories on evolution. There have been many scientists who preceded him. These earlier evolutionists came up with models of evolution that were unfortunately unworkable. One of…show more content…
(Gould, 1980) Darwin did not deny any of this. He regarded it as support for natural selection as an evolutionary mechanism. Darwin's theory was more complex then Lamarck's, but the basic structure was there. Darwin had rooted his theory on the concept of adaptation, just as Lamarck had previously done. Adaptation is the notion of organisms responding to a changing environments by evolving either a form or function of the body that would better suite it in the environment. Lamarck had explained that the method of transfer of information was directly to the organism, the animal would perceive the change and simply respond in the necessary way so that their offspring can be better adapted. Darwin's answer to what the mechanism is was much different.
Darwin spoke of there being two components, variation and direction.(Gould,
1980) Darwin had taken into account that the species did indeed create offspring that were better suited for the environment, just as Lamarck had said. Darwin proposed that instead of direct transfer of environmental change, those that vary by good fortune are better suited for the environment and leave more surviving offspring. A species would have this beneficial trait through random variation. Then, the characteristic would help the animal survive, while the others died off. This ensured that the beneficial trait would get passed on.
This explanation is similar to Lamarkism, with obvious adjustments. Darwin
