We have finally entered our last module on Paleoanthropology and is one of the main reason most field school students have come to the Turkana Basin Institute Field School to learn … Human Evolution! With extensive fossil deposits, the Turkana Basin is one of the most (if not #1) important regions for human prehistory. This module, our instructor is Dr. Matthew Skinner from the University of Kent.
T study began with an introduction to skeletal anatomy and examining the difference between primates and non-primates and where us humans fit in. Living primates are classified into two suborders, Stepsirhines (e.g. Lemurs) and Haplorhines. One easy way to see this division is Stepsirhines lack a postorbital closure where you can see right through the eye socket. You can see this in the right skull cast in the image below.
