How Population Evolve (Genetic drift: This is the fact that variation in gene frequency within population can occur by random chance rather than natural selection. Also known as Sewall Wright effect, How Genetic Variability is maintained within the environment, Natural Selection, Assortative Mating , Hardy-Weinberg Law / Equilibrium, Sexual selection: Concept brought in by Darwin, which stated that, organisms with extravagant hereditary characteristics are more likely to acquire to a mate and reproduce. This traits may make the males more conspicuous and susceptible to predation, Migration is another phenomenon, which causes the in and out flow of genetic genes within populations. This has tendency of uniforming the involved populations. It can also play a vital role in natural selection like mutations by introducing a gene within one of the populations)
