8. Factors in Brain growth

Return to History 8 Human Origins Concepts

Hominids brain began its enlargement journey because they needed to stay where they could drink water and hunt. If they left an area to go somewhere where it was not definite there was a good supply of water to hunt they would die because they lose the water in their bodies because of sweating. This caused the hominids to think about where and when they can go somewhere and they had to decide if they would sacrifice food or water. Hominids were also using their brains more and more with tools and hunting stategies. By manipulating things with our hands our brain was slowly rearranging. With the continually growing use of the brain and the meat becoming a part of our diet it was gradually growing larger.
