Dentition is off and brain too small: not ancestor a) Cooling of the earth lead to changes in the fossil record i. ii. Giant teethed, horse sized grazer a. b. c. African forests, where most current ape territory is. Most fossils found in eastern africa, where a chain of great lakes and volcanoes preserves fossil material. All commonalities between humans and apes, and their differences from monkeys, can be explained by adaptations for arm swinging. It would make the most sense, therefore, that apes and us had a common ancestor, but according to timing and location of a lot of the fossils we have, that may not be true. If not, then there was a lot more convergence going on than you would expect based on statistics. Long curved finger bones that are bigger than foot bones iii.
