Human evolution; sticks and stones (Introduction)

dhw: Thank you for this fascinating article. For some reason it appeared three times, so I have deleted two of the posts. The article clearly shows the complex advances which would have coincided with the expansion of the brain: Australopithecus approx. 450 cc, habilis approx. 600 cc, erectus approx. 1100 cc, Neanderthal approx. 1400 cc, slightly larger than sapiens approx. 1300 cc. Just a quick reminder of the hypotheses offered so far to explain the expansion: random mutations, bipedalism, use of fire, cooked foods (and better diet), the need for extra capacity to implement new concepts (mine), God’s 3.8 billion-year-old computer programme or personal dabbling in advance of new concepts (David’s).

I don't know why the website published it three times. Perhaps impressed by it? You skipped over the argument between us: push or pull? I prefer pull. Bigger to allow for concepts to develop, as shown by artifacts that appear after growth in size.
