Students simulate breeding bunnies to show the impact that genetics can have on the evolution of a population of organisms.
One class period.
A rich class discussion will assist students in a deeper understanding of the 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 selection acting upon genetic variation within a population. (LS4.B)
- Traits that confer an advantage may persist in the population and are called adaptations. (LS4.B, LS4.C)
- Inherited characteristics affect the likelihood of an organism's survival and reproduction. (LS4.B, LS4.C)
- The amount of genetic variation within a population may affect the likelihood of survival of the population; the less the available diversity, the less likely the population will be able to survive environmental change.
- Populations, not individuals, evolve.
- Over time, the proportion of individuals with advantageous characteristics may increase (and the proportion with disadvantageous characteristics may decrease) due to their likelihood of surviving and reproducing. (LS4.B, LS4.C)
- There is variation within a population. (LS3.B)
