Homo Sapiens

  1. 1. H. Sapiens <br />By: Dustin Baker and <br /> Mallory O’Bryant <br />
  2. 2. Classification <br />Kingdom: Animilia<br />Phylum: Chordota<br />Class: Mammalia<br />Order: Primates<br />Family: Hominidae<br />Genus: Homo<br />Species: H. sapiens<br />Subspecies: H. s. sapiens<br />
  3. 3. Theories of Human Origin <br /> Complete Replacement Model <br /> Regional Continuity Model <br /> Partial Replacement Model <br />
  4. 4. Partial Replacement Model<br />Proposed by Günter Bräuer of the University of Hamburg.<br />Postulates the earliest dates for African modern Homo sapiens at over 100,000 y.a<br />Initial dispersal of H. sapiens sapiens from South Africa was influenced by environmental conditions.<br />Moving into Eurasia, modern humans hybridized with resident groups, eventually replacing them. <br />The disappearance of archaic humans was due to hybridization and replacement.<br />
  5. 5. The Regional Continuity Model<br />Associated with paleoanthropologist Milford Wolpoff of the University of Michigan.<br />Populations in Europe, Asia, and Africa continued evolutionary development from archaic H. sapiens to anatomically modern humans.<br />Modern humans evolve in different continents and end up so physically and genetically similar due to gene flow between archaic populations, modern humans are not a separate species.<br />
  6. 6. Complete Replacement Model <br />Developed by British paleoanthropologists Christopher Stringer and Peter Andrews.<br />Proposes anatomically modern populations arose in Africa in the last 200,000 years.<br />They migrated from Africa, completely replacing populations in Europe and Asia.<br />Does not account for the transition from archaic H. sapiens to modern H. sapiens anywhere except Africa.<br />
  7. 7. CroMagnon<br />Nickname:  Cro-Magnon<br /> Man Site:  Cro-Magnon, France<br />Date of discovery:  1868<br />Discovered by:  Louis Laret<br />Age:  About 30,000 years old<br />Species:  Homo sapiens<br />
  8. 8. Anatomy <br />Human body types vary <br />Body size is determined by genes and is significantly influenced by diet and exercise<br />Average height- 5 to 6 feet tall <br />Average weight females- 120-140 lbs<br />Average weight males- 168-183 lbs <br />
  9. 9. Diet<br />Homo sapiens are omnivorous, they consume a variety of both plant and animal material <br />Varying with available food sources in regions of habitation, and also varying with cultural and religious norms, human groups have adopted a range of diets, from purely vegetarian to primarily carnivorous.<br />10,000 years ago we developed agriculture, which altered our diet <br />
