Determine which of the three trees on the next page is more parsimonious based on the sequence variation at 9 nucleotide sites in the ancestral group and the 6 other species. You need to mark changes in nucleotides on each tree. Use the notation where you put the site and then change in nucleotide state. For example, for site 1 where chimps and humans form a monophyletic group, you would put a 1(C) on the branch leading to those two species. 20 pts
