There are a lot of chicken and egg hypotheses on whether walking came first or not.

I think one hypothesis was interesting in that the brain requires a lot of cooling and it took the change in gravity assist and changes in cerebral venous drainage to effect that cooling allowing the brain to develop more.

Another hypothesis that makes some sense is the loss of the strong jaw muscle attachments to the skull ridge was needed for the brain to grow bigger. In the other great apes these muscles and tendons limit brain growth.

Then of course there are the freeing of the hands hypotheses.

I believe the answer is, a lot of different changes in anatomy contributed to the evolution of the brain.

Now there's an evolutionary just-so story I'd like to hear about. Obviously, the ability to fling poo around with your tail has a survival benefit, right?

There's a PhD awaiting the creative researcher who can outline the general theory of poo-volution.

Walking upright and hurling poo? Both facinating, yes, but there is another usually overlooked are of evolution that needs a bit of research and study. In the area of competing to intoduce ones genes to the gene pool and get laid a lot.

The virilty of animals compared to humans indicates that they were far luckier in evolution if the goal of the game is to reproduce and do it a lot. The libido of lions for example during the mating season in very impressive. I remember reading somewhere the male is capable of having sex a few hundred times a day. I googled around but I couldn't find any links to prove it yet. My point is that animals got a pretty good deal from evolution when it comes to their reproduction abilities. Humans have many impressive advantages but not all of them.

I saw a pair of nads on a ram not long ago and they are pretty impressive. You'd need something like that to get a of sheep pregnant during the breeding season. High five for evolution.

Ironically any human with sexual prowess that distinguised himself from the competiton to mate and breed would probably be so busy that he would not have time to go and hunt food for his harem anyway.

It's the kid you hire to guard the operation when you make a run into town to buy more sugar. The kid is placed in a tree with a walkie talkie and lets you know if the revenuers show up.

That is unacceptable. There should be chaperones present whenever chimps are having free cycling estrus.

Distilled monkey ingredients, yum!

An episode of NOVA I believe was discussing this theory, and they implied the decline in the size of the jaw muscles lines up well with the first evidence we have of fire being used as well as correlating with when the digestive tract began to change in order to accommodate cooked meat which correlated with the shrinking of our teeth to better adapt to cooked food, all suggesting the theory with cook fires that groups would gather around the fire to eat cooked meat and food, which would lead to our tendency to tolerate each other in close proximity for extended periods of time as well as a good place to develop language for communication around the fire in such close proximity, stories/discussion/mediation etc.

I thought it was interesting and all of these developments seemed to roughly correlate around each other in the way they presented the evidence.
