Bioanth.3hominidpostcran

  1. 1. Anth 100 Professor McKendricks
  2. 2. <ul><li>Post cranial remains are any of the remains of a skeleton that is not the skull. </li></ul><ul><li>So, everything in that picture except the skull and jaw bone would be considered post cranial. </li></ul>http://www.adaweb.net/Coroner.aspx/CoronerInvestigations/2008Archive/February2008.
  3. 3. <ul><li>Note the longer hip of the chimp, who is not obligate bipedal, and the shorter hip of the obligate bipedal human </li></ul><ul><li>They are important because the skulls are unable to give complete evidence of bipedalism, unlike post cranial remains. </li></ul><ul><li>For example, hip remains tell anthropologists whether the animal was bipedal, indicated by a shorter hip bone, or not, indicated by a longer hip bone (McKendricks lecture). </li></ul><ul><li>The remains of feet tell whether or not the animal or hominid had a divergent toe, indicating that the animal or hominid was arboreal. </li></ul>http://www.anthro4n6.net/lucy/pelvis3.gif
  4. 4. <ul><li>Note the “S” shape of the human spine. </li></ul><ul><li>The shape of the spine is also an indicator of bipedalism. If spine is “S” shaped, it shows that the spine has to balance a head upright. </li></ul><ul><li>The length and bend of the femur also can demonstrate bipedalism. If the femur is long and bends inward, it means that the femur is better shaped to balance a large amount of weight standing up. </li></ul>http://www.eorthopod.com/images/ContentImages/spine/spine_lumbar/lumbar_anatomy/lumbar_anatomy01.jpg
