WebThe population will not only evolve (change in its genetic makeup and inherited traits), but will evolve in such a way that it becomes adapted, or better-suited, to its environment. Natural selection can cause microevolution Natural selection acts on an organism’s phenotype, or observable features. WebA population evolves because the population contains the collection of genes called the gene pool. As changes in the gene pool occur, a population evolves. Mutation. Mutation, …

WebIf the population is in Hardy-Weinberg equilibrium, two things will be true: allele frequencies will not change from one generation to the next (recall our definition of biological evolution), and the actual genotype frequencies … WebToday, we recognize that evolution takes place through a combination of mechanisms: mutation, genetic drift, gene flow, and natural selection. These mechanisms are called the “forces of evolution” and together they can account for all the genotypic variation observed in the world today. summit county colorado judges
