Difference Between Natural Selection and Evolution

Web2 de oct. de 2008 · Natural selection simply requires certain conditions. When they occur, natural selection will occur: There must be variation within the population of organisms. That variation must be heritable. There must be differences in reproductive success based on those heritable differences. WebGenetic drift leads to changes in allele frequencies that are random. Natural selection also causes changes in allele frequencies but it’s not random. 4. Genetic drift occurs in the absence of selective pressures. Whereas, natural selection occurs in the presence of selective pressures. 5.
