Concepts:
Correspondence to the Next Generation Science Standards is indicated in parentheses after each relevant concept. See our conceptual framework for details.

  • Rates of evolution vary.

  • Evolution results from natural selection acting upon genetic variation within a population.

  • Inherited characteristics affect the likelihood of an organism's survival and reproduction.

  • Natural selection sometimes favors heterozygotes over homozygotes at a locus.

  • Heterozygote advantage preserves genetic variation at that locus (i.e., within the population, it maintains multiple alleles at that locus).

  • As with other scientific disciplines, evolutionary biology has applications that factor into everyday life, for example in agriculture, biodiversity and conservation biology, and medicine and health.
