How did Ernst Mayr summarize Darwin's basic ideas? Mayr proposed that Darwin's theory of natural selection could explain all of evolution, including why genes evolve at the molecular level. On the stubborn question of how species originate, Mayr proposed that when a population of organisms becomes separated from the main group by time or geography, they eventually evolve different traits and can no longer interbreed. Mayr declared that the development of many new species is what leads to evolu...
