Fossil casts, literature, and discussion used to explore critical periods in evolutionary transition from ape to human. Anatomical changes in fossil primates of the Miocene and Pliocene epochs (~24-1.8 mya), a time period during which ape species and human ancestors differentiated. Will discuss findings in genomics relevant to the transition (e.g., language acquisition) and aspects of social complexity reflected in the fossil record or by inference from living primates). One course.
