Analogy vs Homology
1. For your homologus traits provide the following information (25 pts): a. Briefly describe (not just identify) the two different species that possess the homologous trait. The point is to provide your reader (and grader) some background on the species in question so we can understand the selection pressures that produced these traits. Don’t short-change this. This should be a paragraph of information, not just a few words and it will be graded as such. (5 pts) Whales and bats are two species that share the homologous trait of the presence of a forelimb.
