Document Summary
Primatologists estimate that there were more than forty varieties (genera) of apes living during this period. Each genus had multiple species, meaning that there are more than 100 ape species recognized and defined for this period. Evolved primarily in africa, but when the earth experienced a period of global warming (16-15 million years ago) tropical and subtropical conditions expanded and the ranges of some ape species expanded too. Ape fossils dating to this period are not just found in africa, but across. Good time to be an ape, the number and diversity of ape species expanded dramatically across much of the old world. We are not descended from chimps, bonobos, gorillas, or orangutans and we did not evolve from them. They have been evolving separately from us, but we share a common ancestor. Evolutionary connection is apparent in our appearance and our behavior, as well as in our genes.
