Evidence of Evolution: Homologous Gene Expression in Four Mammals Species
The purpose of this lesson is to provide an in depth exploration of homologies. Students will interpret phylogenetic trees, explore both structural and genetic homology, and apply what they’ve learned to make predictions about gene expression given phylogenetic relationships. This activity should take approximately one 50-minute class period and is designed for use in an introductory high school biology course.
