Answers. It was Charles Darwin who highlighted the reproductive advantages of environmentally adaptive traits. One of the most important naturalists, he studied evolution and is the one who devised the theory that we and monkeys have the same ancestor.
Natural selection acts on the phenotype, or the observable characteristics of an organism, but the genetic (heritable) basis of any phenotype that gives a reproductive advantage may become more common in a population (see allele frequency).actors that affect reproductive success are also important, an issue that Darwin developed in his ideas on sexual selection, which was redefined as being included in natural selection in the 1930s when biologists considered it not to be very important, and fecundity selection, for example.
