While flipping through the channels, you stop on a television program about primate evolution. The host says that there is a six-million-year gap in the fossil evidence between the latest Oligocene catarrhines and the earliest Miocene proconsulids, which could mean that primates disappeared from Earth and evolved anew some time later. What do you tell your roommate about what you have just heard?
A. "The primates in that six-million-year gap were evolving in South America, not Africa!"
B. "The resemblance between the Fayum catarrhines and the Miocene proconsulids in skull form and dentition suggests an evolutionary relationship, even if the direct fossil evidence isn't there!"
C. "These primates were whisked away by aliens and put back a few million years later, so of course there is no fossil evidence!"
D. "It's unlikely that anything important evolved in that time, so the gap in the fossil record doesn't matter!"
