Natural selection v.s Sexual selection
Natural selection and sexual selection is a selection process in which favorable traits in an individual are favored, by either nature or members of the opposite sex. Natural selection as Darwin explains is the survival of the fittest, on the other hand Dawkins describes this concept as the survival of the stable. Darwin describes natural selection as a process that filters out the weak at any age and allows on the strongest, with the best traits to survive. Sexual selection, Darwin elaborates, is a process at which the mates get to choose the favorable traits even if it is not favorably naturally. For example the huge, long, elaborate tails on the peacock, things that can not be describe though the process of natural selection.

You brought up the main points of each selection but I would have like to see more detail concerning their differences as well as the differences between the authors' perspectives.
ReplyDeleteGood post! Don't forget that Darwin's Natural Selection is shaped by the environment, and that Dawkin's also makes sense of Sexual Selection too by having the female use either the rearing strategy or the best gene strategy to choose a mate.
ReplyDeleteThe first sentence seems like you're lumping the two concepts together and could be mistaken by some. More elaboration on Dawkins would be nice, but good coverage of Darwin.
