Consider the anatomy of the following six genera: Branchiostomata (Amphioxus), Petromyzon (Lamprey), Squalus (Dogfish), Perca (Perch), Necturus (Mudpuppy) and Lithobates (Bullfrog). Recall that you had the opportunity to study these animals in the laboratory portion of this course. Construct a table listing the important characters of each of these six genera that you think would be useful in constructing a cladogram or phylogenetic tree. Indicate which characters might be plesiomorphic (generalized for some or all of these taxa) and which...

Analysis based on two individual genes (gene trees) may imply two different phylogenetic relationships among a group of species. List three possible reasons for this (1), and explain how one of them works (2). If only one phylogenetic tree accurately represents the true evolutionary history of these species, what might we do in order to determine which one is correct (2)?
