The tree аbоve shоws five shаpes thаt represent five different species. Each species has twо 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? [blank1] 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? [blank2]
