What is the genetic basis of this change? (Wallaces many other contributions, especially in biogeography, were of course noted and lauded.). Because resources are limited in nature, organisms with heritable traits that favor survival and reproduction will tend to leave more offspring than their peers, causing the traits to increase in frequency over generations. Darwin did not borrow any idea on evolutionary divergence from Wallace - who in fact had no such theory of his own. Darwin did not cheat Wallace out of his rightful place in history - Why In the theory of natural selection, organisms produce more offspring than are able to survive in their environment.
