  1. 1) A synapomorphy • A) Is shared by all members of a clade of interest and also by their more distant ancestors as well as other groups • B) Is a trait that is similar in unrelated groups of organisms because of similar past selection • C) Is a trait shared by a clade of interest that is a derived feature of that group • D) Is the morphology of the synapse

  2. 2) Which node is a polytomy? = C

  3. 3) Which nucleotide residue is a synapomorphy of whales and hippos? 142 162 166 177 192

  4. 4) A really well supported phylogeny would • A) show concordance among multiple data sets • B) depend upon the analytical technique used • C) only use a cladistic approach • D) confirm the relationships that you think should be correct before you got data • E) always include humans as an outgroup

  5. Questions 5), 6), AND 7) • 5) which is paraphyletic = A • 6) which is polyphyletic = B • 7) which is monophyletic = C A) B) C)
