Introduction to Making a Cladogram Diagram for the Worm Phyla
Read the inforamtion on the link below to make a cladogram of your design for the three worm phyla covered in class. The caldogram will show the evolutionary relationship you believe exists between the three phyla, and include the changes that occurred from one point on the cladogram to the next. Basically, where lines converge at a point on a cladogram, there exists a common ancestor of the lines that lead from that point. The lines are where evolutionary changes occur. You will describe what you think each ancestor’s characteristics are, and what changes occurred on the lines as they lead away from it.
