Look again at Figure, and this time focus on the diversity of sequences within each species. The length of the colored lines indicates the degree of genetic diversity within each species.

a. Do humans have a large or small amount of genetic diversity, compared to the other primates studied? Which other species show similar patterns to humans? Why do you think some species have greater diversity than others?

b. One of the human sequences is distinct from the other five. Can you guess the geographic location of this person?

Figure. Phylogeny of mitochondrial cytochrome oxidase II alleles in humans and the African great apes Ruvolo and colleagues estimated this tree using the maximum parsimony method. From Ruvolo et al. (1994).
