|Making Cladograms: Phylogeny, Evolution, and Comparative Anatomy|
This lesson introduces students to the building of cladograms as evolutionary trees showing how "shared derived characters" can be used to reveal degrees of relationship. Given some groups of organisms and some of their distinguishing characteristics, the students will construct a cladogram. Given a cladogram, the students will properly interpret and analyze that cladogram in terms of recognizing the concepts of common ancestry and degrees of evolutionary relationship; and given a cladogram of vertebrates and some new unclassified vertebrates, the students will show where the new animals would be placed.
