There are four forces of evolution: gene flow, genetic drift, natural selection, and mutation.Learners Assessment Guide

Please discuss the possible ways in which one or more of these evolutionary forces might operate to produce a huge amount of anatomical and behavioral diversity seen in the various primate species, today.
