A) Majority-rules consensus of 10,000 trees generated using a Bayesian approach. Support values greater than 0.85 are indicated on relevant nodes. The major platyrrhine clades (A, B, C, and D) are indicated. Within clade D, members of subfamily Alu Ta10 are underlined. B) Majority-rules consensus tree of 107,470 equally parsimonious trees generated as described in the Methods section. Bootstrap values for nodes with greater than 50% support are indicated. Sequences representing well-supported clades from the Bayesian tree are also indicated.
