Document Summary
Different from other primate in form of teeth, jaws and brains. Fossils date over 6m-1m ya: homo. Earliest members included h. habilis and h. rudolfensis. Bipedalism ability for a mammal to walk on 2 feet. Related to the foramen magnum opening in the base of the skull for the passage of the spinal cord ; in quadrupedals, the aperture is located at the back of the skull. Shown through fossils as far as 6m ya. Transportation: allowed for infants to be carried but reduces speed predators would be given the advantage, benefits of being able to transport food or offspring is offset by slower speed and less mobility. Provisioning: food sharing and cooperation produced reproductive strategy that favoured sexual fidelity and long-term relations between male and female. Thermoregulation models: bipedalism allowed for fast movements increased heart rates, sweating (in reaction), less body hair. Hominid jaw and teeth allowed for the chewing of an omnivorous diet.
