Students simulate breeding bunnies to show the impact that genetics can have on the evolution of a population of organisms.

Author/Source:
WGBH

Grade level:
13-16

Time:
One class period.

Teaching tips:
Though developed for grades 9-12, this activity is quite appropriate for the undergraduate level and can be enhanced by connecting the activity to primary literature investigating a specific series of changes such as that found in the Grants' work on finches.

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

  • There is a fit between organisms and their environments, though not always a perfect fit.

  • Some traits of organisms are not adaptive.

  • Evolution is often defined as a change in allele frequencies within a population.

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

  • An individual’s fitness (or relative fitness) is the contribution that individual makes to the gene pool of the next generation relative to other individuals in the population.
