This lesson plan involves comparison of amino acids to create a phylogenetic tree of primates. Students will also use other species information to draw conclusions about evolutionary relationships.

Constructing phylogenetic trees may be a daunting task for students, but this lesson plan is a simulation of what molecular biologists must do to determine relationships. This plan is for students who have a good grasp of DNA structure...

Use molecular information and observe female response patterns to learn about the mating calls of Physalaemus frogs. Examine the evolution of female preference for particular call characteristics.

YouTube video continues the discussion of molecular phylogenetics and reconstruction of the tree of life.
