Charles Darwin's Concept of Natural Selection and Sexual Selection

Paper Summary:

In this paper the author reviews the books that Darwin wrote; "Origin of Species and The Descent of Man", which lead to his theories of natural selection. He discusses the theory of how types of living things (species) arise in different places and how the four theories of Darwin were developed ; diversity, competition , survival of the fittest and adaptation. The paper concludes with natural selection and the concepts of sexual selection that support Darwin's theory of the origin of species.

From the Paper:

"However, natural selection is not the only process responsible for evolution; another process is sexual selection. Darwin anticipated that sexual selection would be a potential criticism of evolution through natural selection and therefore put forth great effort to explain these occurrences. Thus, sexual selection refers to selection acting via effects on mating success. Natural selection, then, refers to effects on other fitness components like viability, survival. Darwin recognized the two processes as mutually exclusive."
