The Evolution of Primate Intelligence It appears that humans and non-hominid primates share a common ancestor that dates back to about thirty-six million years ago ( Sabbatini 2001). As such, we can study the evolution of primate intelligence by looking at the information we can gain from contemporary manifestations of related species of primates, starting with the Lemuroids and the Tarsiers, moving to the monkeys, and finally apes and humans. The evolution of primate intelligence tends to be linked with the evolution of a larger brain size through these primate grades, which in turn has been theorized to be the result of changes in social organization and foraging strategies on the part of these animals (Rifkin 1995, Falk 2007).
