Overview: Students learn about natural selection in rabbits by observing the effects of a virus on the Australian rabbit population.Author/Source: Chamberlain, Don Grade level: 9-12 Time: Four class periods. Teaching tips: This activity assumes that students have received information about viral structure, the viral replication cycle, differences between RNA and DNA viruses, and some effects of viruses on living tissues. 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)
- Inherited characteristics affect the likelihood of an organism's survival and reproduction. (LS4.B, LS4.C)
- 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)
- Speciation is the splitting of one ancestral lineage into two or more descendent lineages.
- As with other scientific disciplines, evolutionary biology has applications that factor into everyday life.
