Age. A considerable amount of material of the Cro-Magnon 

 man is available for study, and this material shows that human 

 morphology has changed very little during the last 40,000 years. 



Fig. 179. — Prehistoric men. A, Java Man, Pithecanthropus erectus, lived 

 approximately 1,000,000 years ago. Portion below irregular line restored. B,
