  1. Chapter 11 Homo sapiens sapiens

  2. Chapter Outline • The Origin and Dispersal of Homo sapiens sapiens (Anatomically Modern Human Beings) • The Earliest Homo sapiens sapiens Discoveries • Technology and Art in the Upper Paleolithic • Summary of Upper Paleolithic Culture

  3. Homo sapiens sapiens • Members of early Homo sapiens sapiens are our direct kin. • They were much like us skeletally, genetically, and (most likely) behaviorally. • They were the first hominids that we can confidently refer to as “fully human.”

  4. Questions About the Origin and Dispersal of H. sapiens sapiens • When did H. sapiens sapiens first appear? • Where did the transition take place? In one region or in several? • What was the pace of evolutionary change? How fast did the transition occur? • How did the dispersal of H. sapiens sapiens to other areas of the Old World take place?

  5. Theories of Human Origins • Complete Replacement Model • Regional Continuity Model • Partial Replacement Model

  6. Complete Replacement Model (Recent African Evolution) • Developed by British paleoanthropologists Christopher Stringer and Peter Andrews. • Proposes anatomically modern populations arose in Africa in the last 200,000 years. • They migrated from Africa, completely replacing populations in Europe and Asia. • Does not account for the transition from archaic H. sapiens to modern H. sapiens anywhere except Africa.

  7. Partial Replacement Model • Proposed by Günter Bräuer of the University of Hamburg. • Postulates the earliest dates for African modern Homo sapiens at over 100,000 y.a.

  8. Partial Replacement Model • Initial dispersal of H. sapiens sapiens from South Africa was influenced by environmental conditions. • Moving into Eurasia, modern humans hybridized with resident groups, eventually replacing them. • The disappearance of archaic humans was due to both hybridization and replacement.

  9. Regional Continuity Model(Multiregional Evolution) • Associated with paleoanthropologist Milford Wolpoff of the University of Michigan. • Populations in Europe, Asia, and Africa continued evolutionary development from archaic H. sapiens to anatomically modern humans.

  10. The Regional Continuity Model(Multiregional Evolution) • Question: How did modern humans evolve in different continents and end up so physically and genetically similar? • Explanation: • Due to gene flow between archaic populations, modern humans are not a separate species. • Earlier modern H. sapiens did not originate exclusively in Africa.

  15. Techniques for Dating Middle and Upper Pleistocene Sites

  16. The New World • Ancestors of Native Americans reached the New World through migration over the Bering Land Bridge over many millennia. • Debates continue, but at present, the only direct evidence of hominids in the New World date to about 12,000 y.a.

  17. The Upper Paleolithic • Cultural period began in western Europe approximately 40,000 years ago. • Five industries based on tool technologies: • Chatelperronian • Aurignacian • Gravettian • Solutrean • Magdalenian

  18. Cultural Periods of the European Upper Paleolithic

  19. Cave Art • Majority comes from southwestern France and northern Spain. • Grotte Chauvet • Dating has placed the cave painting during the Aurignacian period more than 30,000 y.a. • Images include stylized dots, human handprints and animal representations. • Among the archaeological traces are dozens of footprints on the cave floor produced by bears as well as humans.

  20. Africa • Rock art is found in southern Africa dating to between 28,000 and 19,000 y.a. • Personal adornment dates back to 38,000 y.a. in the form of beads made from ostrich shells. • Excavations in the Katanda area show remarkable bone craftsmanship. • Intricate bone tools resembling harpoons were made from the ribs of large mammals.
