Is genetic drift a mechanism of evolution
WebIn conclusion, natural selection, mutation, genetic drift, and gene flow are the four mechanisms of evolution that are responsible for the diversity of life on Earth. Each of these methods contributes to the genetic variation that is present within populations and is a factor in the process of evolution. Each mechanism works on a different ... WebMechanisms of Change Changes to allele frequency within a gene pool (evolution) can result from five key processes: Mutation: A random change in the genetic composition of an organism due to changes in the DNA base sequence Gene flow: The movement of alleles into, or out of, a population as a result of immigration or emigration

The Hardy-Weinberg equilibrium principle says that allele frequencies in a population will remain constant in the absence of the four factors that could change them. Those factors are natural selection, mutation, genetic drift, and migration (gene flow). In fact, we know they are probably always affecting populations.
