Teaching tips:
The exercise does a good job addressing the process of genetic sequence change, but itís short on making the role of natural selection clear. Supplement with additional discussion or a short video on natural selection.

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

  • Evolution is still continuing today.

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

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

  • Natural selection can act on the variation in a population in different ways.

  • 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.
