Using these character states and the methods we learned in class, construct the most parsimonious phylogeny for these seven taxa and draw (or insert a photo of) this tree below or on a separate page. Remember that the most parsimonious tree is the one with the fewest possible changes. Next, indicate with labels and arrows where each change occurred (i.e., where derived character states first appeared) on branches of the tree. For example, if there was a change from 'wings’ to ʻno wings’ on a branch, you would indicate either 'no wings’ or 'wings lostť

Part I: Construct a phylogeny Below is a list of seven hypothetical, currently-living species (A-G), and eleven of their character states (i.e., traits). You will use these traits to construct your tree. Species Character states green еyes green no no egg wings claws hair A scales tail carnivore teeth spots horns layer green eyes green no egg В scales wings horns tail carnivore hair teeth spots claws layer egg layer green green no no scales wings claws tail carnivore hair spots eyes horns teeth no no no egg no no scales red eyes wings claws layer no tail carnivore spots horns hair teeth no no egg layer no no E spots red eyes horns scales claws tail carnivore wings hair teeth no no no live no F spots red eyes wings claws carnivore tail hair scales horns birth teeth no no no live no G spots red eyes wings claws tail herbivore hair scales horns birth teeth Assume that the extinct ancestor of this group, at the root of the phylogenetic tree, had the following features: no spots, no scales, red eyes, wings, claws, no horns, live birth, tail, herbivore, hair, and no teeth.
