mechanisms of evolution. Another well-known mechanism is random genetic drift. This is a mechanism that results in fixation (or loss) of alleles by purely random processes. The topic is thoroughly covered in all the major textbooks—it is not controversial. Unless you deny the existence of random genetic drift‚ you must agree that some of evolution is entirely due to chance events. The controversy is over how much of evolution is due to drift and how much is due to natural selection. Excellent arguments have

It is important in evolution because of the effects it has had on evolution and taxonomic diversity‚ brought about by the collision and moving apart of landmasses. The drifting apart of land masses brings about vicariance‚ where organisms are split up by the development of barriers‚ isolating descendent populations which then evolve
