  The tree above shows five shapes that represent five different species. Each species has two traits: a color and either pointy or rounded edges.   In case it’s difficult to see the traits by looking at the shapes, here are the species’ traits: A: yellow and round. B: orange and round. C: orange and pointy. D: blue and round. E: blue and pointy.   Question 1: Species B and C are the only species that have the orange color trait. Based on your best hypothesis about where on the tree color traits evolved on this tree, is the orange color of species B and species C homologous or analogous?     Question 2: Species C and E have pointy edges, while species A, B, and D have rounded edges. Based on your best hypothesis about where on the tree pointy edges evolved, are the pointy edges of species C and species E homologous or analogous?

This question is to be sure you are here in class with us taking the exam. Sending this answer to anyone else is a violation of academic integrity (it is cheating). If you are taking this at an approved DRC proctored location you can leave this question blank (or take a guess). What is your lecture TA’s favorite animal?
