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 leads to adaptation, in which an organism's traits conform to the environment's conditions for existence. Uloborid spider eggs and spiderlings. In any given generation, populations tend to create more offspring than can survive to reproductive age.f ugly, dumb, weak individuals pass on more genes, those traits will prevail in future generations. Whenever one organism leaves more successful offspring than others, in time its genes will come to dominate the population gene pool.
