running shaped evolution?

Wow...that is great info....of course I was already sold on the effectiveness and timing of post workout carbs and protein, but great to know. Somehow I don't think I will be taking any tongue or liver to the gym for PWO.

Ranks up there with Take your fish oil because "Cavemen used to bash in heads and eat the brains...brains are high in DHA and probably shows how cavemen evolved quickly".

For more fun explanations, just ask Robb about cultured food sometime.

P.S. Not sure about the other tribes, but the Kalahari Bushmen used hoodia as an appetite suppresant.

I think this article is really missing the boat on the whole "what defines us as humans" thing, because nowhere did I see any mention of opposable thumbs! I would think that whatever selective pressure blessed us with the ability to use tools has had a far greater influence on our hunting practices than the fact that we have bigger asses than apes! Correct me if I'm wrong, but didn't opposable thumbs come before any of these other changes besides walking upright?

Actually, no.

Opposable thumbs seem to show up in the fossil record at approximately the same time as the "running" adaptations Bramble and Lieberman are describing in the article. Not necessarily before. Also opposable thumbs are not necessarily the sole province of the genus homo. So, thumb="human" is a tough call. The big brain, complex speech, light bodied (weak) and fine motor control are all part of the collection of "human" goodies.

the hows and why's of evolution are fascination to me. To be sure a few things happened in fairly close time proximity:
1-decrease in gut size
2-increase in brain size
3-increased stature and alteration of the pelvis
4-opposable thumb

Human skeletal anatomy has not changed much from the neck down since H. Erectus...nearly 2 million years! It is efficient and works very well as is evidenced by the conservation of many structural traits. it's tough to tell about the software of the brain but it does appear H. Sapiens experienced a serious leap in cultural transmission. H. neanderthalensis was smart enough to pick up on much of this, but never independantly developed it.

This in my mind is the "fractal" landscape Devany describes...information and evolution occurring on the genetic level which creates changes that creates memes...purely "thought" or cultural changes...which feedback and alter genes. Interesting stuff.

Huh? I thought the jury was still out on this.

[Steve Shafley]

Neanderthal obviously couldn't compete.

I think they were more strict carnivores than H. Sapiens and while physically superior, were less adaptable.
