Natural selection is the selective development and reproduction of organisms due to various phenotype disparities. The shift in the heritage characteristics of a population over time is a crucial factor for evolution. Charles Darwin popularized the term ' natural selection'.Feb 6, 2015 · However, in order for Darwin’s idea about natural selection to work, he noted four things that needed to be true, otherwise known as Darwin’s Four Postulates of Natural Selection. The first postulate was that there had to be variation in the phenotypes, or the traits, of individuals within the species. Darwin's postulates have no hidden assumptions nor do they require uncritical acceptance. - each postulate is testable via empirical evidence and experiment - indeed, much of Darwin's text is concerned with addressing what others considered weaknesses in his theory eg:Sep 23, 2004 · Chapter 3.
