Connecting Concepts: Natural Selection 3: Microevolution: Evolution in a Population
Students play the role of predators on moths on a tree trunk. Then, they play the role of biologist, analyzing the changing gene frequencies of the moth population and determining if the population evolved over three generations. Students will: 1) collect data by eating moths; 2) calculate gene frequencies for each phenotype over three generations; 3) interpret graphs of data their data to determine if microevolution occurred; and 4) explain how selection acts on populations.
