ANTH 1001 : Anthropology Test 3 Notes
Document Summary
The big 3 : culture, brain size, bipedality. Skull: foramen magnum (located centrally underneath the skull, posteriorly located in knuckle walking apes (quadrupeds) Skeletal adaptations for bipedality: spinal curvature, s-shaped (human, quadrupeds (spine not as curved, balance, pelvis shape (ilium/ilia, rounded, broader than it is tall (human, ilium, front to back (anterior to posterior) (human, quad. Taller than it is broad, flat, rectangular. Shorter neck: feet, biped, toe is in line with the rest of the toes, propel forward, longitudinal arch, quadruped. Grasping: limb ratios, great apes, long arms, short legs, humans, long legs, short arms. Hypotheses for bipedality: freeing the hands, man the hunter, woman the gatherer, provisioning, better view of open country, energy efficiency, uses less energy when you use two limbs when you go long distance. Lumpers: paleo anthropologists want to put fossil records into fewer categories/species. Splitters: more preferable to separate the fossils into different categories until there is more data.
