What's right and wrong?

ugh, u search for it!
i got it from science shows on t.v, which talked about the evolution of men, from the first apes to walk on 2 legs (which ate meat! unlike any other apes at that time, i think), to the neanderthal man (maybe there was an episode about us too that i missed)...
well, if i remember correctly, it wasnt only for meat that we grew big brains, but meat had essential vitamins and other stuff that we needed...
after all, dont forget that unlike now, the diet back then (millions of years) was alot smaller and it was more like "just eat what u can" so maybe fruits that contains iron for example was extra-rare, so in this case, eating meat is a great solution!
u can just figure this stuff out, plus, from what i understand, b12 vitamin affects our intelligence and brain volume and stuff like that....

also, something helped us develop tools, prehistoric-humans werent as innovative as we are, they took the world for granted and discovered tools mostly by accident (also was said in that one science program).
i think it was a bbc program, and i kinda believe it although it's filled with speculations.

That's just theory, you know.

There's a theory why we are so smart, and apparently, it was due to our lack of water-sources when the heat-seasons of the year came over us and we had no water left, forcing us to think out of the box to survive. Thus, human "created" imagination.
