Of course, it is a proven fact that different parts of the world have advanced more then others. Some of it is because of genetics.

In short, some breeds are stupider than others.

My theory is that the people of the Middle East have had their brains baked to death for so many centuries, that it's permanently damaged their DNA.

That's not to say that there aren't some brilliant Arabs. I've met a few in my time, but I just think that humans weren't designed to withstand 130 summers indefinitely. Exposure to that sort of extreme temperature over millenia has simply got to damage the gene pool in some way.

Humans just have not thrived in those desert areas.

Then the same should hold true for the Inuit and other inhabitants of the zones bordering on the Arctic Circle?
