Animals cladogram 10 points. Use the following characters and list of organisms/groups of organisms to create a cladogram. A few of these, such as the Hox genes, we did not discuss in class, but you will find them described in chapter 34. You can use numbers to refer to the characters on your cladogram, and many "tick-marks" will represent multiple characters (like our plant cladogram we did in class). Don't let perfection be the enemy of completion of this assignment...

11. For this question, refer to FIG. 24.2 (p. 487) "The family tree of the lesser and great apes."This figure shows the derivation of "earlobes". Assume that evolution has not reversed this character state in any of the descendants of this ancestor which evolved earlobes. Given this, what do we know about earlobes?

All of the features below are features that characterize humans,
though very few of them are unique to humans. Rather, most of them
are present in our species because of our evolutionary history
(they were present in an ancestral species at some point in time,
and eventually passed on to us). For example, the bilateral
symmetry that characterizes the human body plan is a feature that
evolved in a primitive animal species that lived hundreds of
millions of years ago;...
