Early Archaic Homo sapiens
• Classification complex & unresolved• Archaic H. sapiens appears c. 700,000 ybp• Wide distribution, in the Old World• Brow ridges prominent and arched• Later forms have higher cranial vault and
reduced tooth size.• Mean brain size: 1,330 cc• Mean brain size of H. erectus: 1,003 cc
