List the four shared derived characteristics of chordates. Which invertebrate subphylum shows all four characters as intact, functioning structures in the adult? Which character is present, in intact, functioning form, in an adult human?
Homework Answers
The four derived shared characters of chordates are:
a notochord,
a dorsal hollow nerve cord,
pharyngeal slits, and
a post-anal tail.
All of these characteristics are observed at some point in chordate development.
Cephalochordata subphylum shows all of the four characters intact in the adult.
The dorsal nerve cord is still present in the functioning form in the humans.

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).
