Please draw in a full 8×10 piece of paper, a comprehensive phylogeny of extant protochordates and vertebrates, starting with the protostomes as the root group. This phylogeny should include two synapomorphies of each group, as well as the main evolutionary changes in the time axis. These should include all the chordate characteristics, plus dorso-ventral inversion, appearance of paired appendages, appearance of jaws, neural crest cells, vertebral column, cranium, etc, as well as the extant anamniotes and amniotes (14 pts). This question merges 3 individual questions from those 3 lectures. Please use this type of phylogenetic representation with as many branches as needed.
