WebThe core of Darwin's theory is natural selection, a process that occurs over successive generations and is defined as the differential reproduction of genotypes. Natural selection requires heritable variation in a given trait, and differential survival and reproduction associated with possession of that trait. WebOct 1, 2003 · Based on the evidence of Darwin's finches, evolutionary changes are indeed going on. Speciation: The beginning Speciation begins with the divergence of a population and is completed when two populations that have diverged on different islands establish coexistence with little or no interbreeding ( Mayr 1942, Grant 2001 ).
