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?

I would tell the room mate  that what i just heard was the resemblance between the Fayum catarrhines and the Miocene proconsulids in skull form and dentition which suggests an evolutionary relationship, even if the direct fossils evidence is not present. Primates are divided into two groups; the prosimians and anthropoids. Monkeys evolved from Prosimians during the Oligocene Epoch while Apes evolved from the Catarrhines in Africa during the Miocene Epoch. Apes are then divided into the lesser apes and the greater apes.

The answer would be sand and gravel
