Charles Darwin’s theory of evolution had three main components: that variation occurred randomly among members of a species; that an individual’s traits could be inherited by its progeny; and that the struggle for existence would allow only those with favorable traits to survive. Although many of his ideas have been borne out by modern science, Darwin didn’t get everything right: traces of Jean-Baptiste Lamarck’s outdated theory of evolution remained in Darwin’s own. He was also unable to correctly establish how traits were inherited, which wasn’t clarified until the rediscovery of Gregor Mendel’s work with peas.
