BIOL 300 Lecture Notes - Lecture 3: Fierce Creatures, Lamprey, Clavelina
Document Summary
Introduction: practice constructing phylogenetic trees the fierce creatures . Character matrix from handout - "the fierce creatures" Phylogenetic trees for the fierce creatures: the following two trees are equally parsimonious, since they both require the fewest number of evolutionary changes to explain the shared derived characters present in these organisms. Note that other phylogenetic trees are also possible, but they are less parsimonious. Table 2. 1 character matrix (data collected from preserved specimens in lab) Based on your observations of these preserved deuterostomes and on the information in the lab manual about deuterostome taxa (pages 37-41), classify each of the five deuterostomes into the appropriate taxon (echinodermata, hemichordata, cephalochordata, urochordata, or. Based on the morphological characters that you investigated in this lab, the most parsimonious phylogenetic tree is: The phylogenetic tree from the lecture notes and from the 7/8th editions of our textbook:
