Detailed explanation-1: -Genetic Drift Example The population which have recovered today show very few genetic variations. Consider a population of rabbits with brown fur and white fur, white fur being the dominant allele. Due to genetic drift, only the brown population might remain, with all the white ones eliminated.
Detailed explanation-2: -They are: mutation, non-random mating, gene flow, finite population size (genetic drift), and natural selection.
Detailed explanation-3: -Geographical Isolation (allopatry) The proximity of the various islands has permitted enough migration of Darwin’s finches between them to enable distinct island populations to arise. But the distances between the islands is great enough to limit interbreeding between populations on different islands.
Detailed explanation-4: -Natural selection can act against maladaptive hybridization between co-occurring divergent populations leading to evolution of reproductive isolation among them.
