Darwin’s theory of evolution by natural selection represents a giant leap in human understanding. It explains and unifies all of biology. Darwin’s theory actually contains two major ideas: One idea is that evolution occurs. In other words, organisms change over time.The mechanism that Darwin proposed for evolution is natural selection. 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's 4 postulates. 1.
