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

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

  • Natural selection and genetic drift act on the variation that exists in a population.

  • Variation of a character within a population may be discrete or continuous.

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

  • Traits that confer an advantage may persist in the population and are called adaptations.

  • Scientific knowledge is open to question and revision as we come up with new ideas and discover new evidence.

  • Scientists test their ideas using multiple lines of evidence.

  • Our knowledge of the evolution of living things is always being refined as we gather more evidence.

  • 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.
