Them Sharks eat a lot of fish, but they have dam small brains.

Crocodiles eat a good variety of meat and fish. What happened to them.?

Natural selection picks out the fittest (to survive and rear offspring), not the brainiest. In humans, the fittest were the brainiest purely because of the ecological niche we happened to be in.
If I put you in a ring with a lion, who would win?
If I put a really strong, but dumb guy in the wilderness, and pitted him against a really brainy guy of average strength, who would more likely prevail?

That said, it sure gets a lot easier for natural selection to pick you out if you're still around, and opening up your diet to include meat and fish certainly helps. Various random hypotheses suggest that Homo Sapiens prevailed and Homo Neanderthalus (which had a larger brain) did not, because the latter failed to incorporate fish into its diet.
I'm still not sold on other reasons for the evolutionary development of human intelligence being contingent on the nutrients available solely from meat and fish. Vegetarians get by perfectly fine by getting all the critical nutrients from elsewhere.

When you look at the evolution of various monkeys and apes in the wild in their respective niches, you do have to always take food supply into account, but this is largely due to the *glucose metabolism* requirements engendered by a high brain>body ratio.

The accepted theory now on why we survived is very simple, has nothing to do with brain power and makes perfect sense. The neaderthals were a stocky, extremely powerful species who were great ambush predators who thrived in woodlands as their low centre of gravity was great for physically pushing spears into deer and such animals, but they were useless in open ground, after the ice began to melt away they were faced with a totally new environment full of open meadows and fields and they simply did not have the abiltity to ambush their predators anymore. Homo sapiens were much more suited to this enviironment as they had stamina on their side and were able to stalk prey over gretaer distances. They also designed much better weapons suitable for throwing further in open ground which is hugely important as its not as possible to get close to the prey without cover.
Neandertahls were perfectly adapted for cold conditions and when the climate became milder woodland became less common, they could simply not compete with us homo sapiens.

which idiot started a thread on evolution on a poker forum

everyone knows poker players havent evolved yet

No. Any survival advantage given to vegetarians due to the health benefits of their diet is outweighed by the easier sourcing of foods in the varied diet of the omnivores. The omnivorous nature of humans runs deep into their genes, its hard to start teasing this apart into specific genetic differences that express themselves as an overwhelming preference/disdain for meat.
Take into account the fact also that Natural Selection, one of the two main underpinnings in evolution, does not really exist in a big way for humans, since we have culture, and thus can poke the savagery of nature in the eye.

Humans won't be around in 100 000 years anyway, we'll be blown to bits long before then.

Is this for some kind of essay?

100,000 years? the way the world is now human kind will be lucky to see the next 100 years!

Guess we are the lucky generation been born now....

I'm pretty sure I said we needed both to evolve into us.

I also didn't say meat is necessary for us today, just for our evolution

can i just say the human race is not going to destroy itself.

As much as people like to think it will end in nuclear war blah blah blah, it still wouldnt mean an end to the human race. There are facilties in britain and the other big countries (france, canada, usa, germany, russia etc) in the world that are hundreds of feet under the ground where the "top" people or in other words the people who could rebuild this planet would be placed in the event of a natural disaster, alien invasion (lol) or nuclear war.

we will never compleyely die out, we may do a good job of cutting the numbers down but we are here to stay!

If it was necessary for our evolution it would be necessary for us today.

we dont need meat to evolve, fact!!!

no, it was necessary for our brains to evolve into what they are now but vegetarians can source what they lack from meat from elsewhere.

we don't need meat to evolve further, but we did need meat to evolve into us

wowow, so somewhere in our evolutionary history (where? pre-modern man, prehominid, prehominoid, where?) we went through a period of evolutionary development that required MEAT in our diet to give us that oooomph towards greater brain size, and then.......became a creature that did not require it to sustain that brain size? wow! where is this from?
