Lab-Aids: Evolution - Examining Fossil and DNA Evidence Kit
In Activity 1, students investigate how fossil whales provide a line of evidence in support of the theory of evolution. Students then apply the theory of natural selection to whale evolution, using anatomical adaptations to infer the habitats, lifestyles, and evolutionary relationships of extinct species. In Activity 2, students examine classification from an evolutionary perspective. They compare DNA sequences from a number of vertebrates and create an evolutionary tree. Developed by SEPUP.
