Hello,
I was interested in human consciousness, and I picked up Daniel Dennett's book "Consciousness Explained" and something he claims there got me thinking:
He says that human brain evolved from chimp-size to homo-sapiens-size in a period after humans learned to stand on 2 feet, and before the appearance of language. What was the evolutionary "pressure" then, that caused this evolution, if we didn't need it to be erect and we didn't use it for language at the beginning?
The book itself isn't exactly new, is it possible that there have been some research that shows different order of events? If so, could you point me to such research?
