Lab Assignment 3: Chondrichthyes Diversity
Name: Karissa Beloyan
What characteristics are unique to the Chondrichthyes?
Which of these characteristics are
plesiomorphic (ancestral) vs. synapomorphies?
For each of the following clades, who belongs within that clade? What
features/synapomorphies make each of these distinct? Can you find evidence of
those features on the specimens/pictures of some of the taxa within the clade?
(Also, for practice with the phylogeny, who is each clade’s sister taxon?)
