As I said earlier I'm just a layman so I don't know for sure.

Ah just offering my point.

I would imagine that would play a part.

Theres also another factor, resource availability

We have the japs that got on with very little metal and the euros that got on with well, enough of it

So how hard it will be to gather food.

Pleantyful with no seasons would be like africa or south america?

Pleantyful with seasons is like europe.

True have less resources available would create alot more pressures.

Or just change the focus

Like alot of resources can mean two things

They dont bother with innovation, or they have more time to innovate.

With that I would point out that Africa is very resource rich which would make it a easier place to live. Which is why I think that blacks evolved the way they did. They just had a easier environment which prevented selection of genes for intelligence and prevented innovation.

Hell, id say the same for the mid east before the sahara started eating everything

Also, you said earlier

Very ture.

the lack of seasons

No reason to unite against a common threat

all very true.

So it became of the smartest

To the strongest

The ones that survived were the best at fighting and taking.

And time spent innovating was time spent not training and fighting

And well, concentrated resources would create a culture of fights over resource points

I would also add the ability to organize. The Europeans and Asians created towns which organized into cities, then organized into countires and then into empire.

Though id argue that communication made it easier to do so

And well, it was like a race

YOu had to choose a side or be wiped out

True you can't organize if you can't communicate effectively.

All that needed to happen was one tribe getting bigger than another through growth.

And it dominoed from there.

And well, it got to a point where the nation couldnt communicate within itself efficiently.

And thats how it would then collapse when the people were too spread out to have a common goal.

Do Indians and Pakistanis count as Asian?

I would say evolution tends to take shortcuts. I think a good example is visual spatial intelligence which allows people to navigate over long distances but that bassicly useless when maps were invented.

Arabs? Mesopotamians?

Actually, you could argue that innovation also makes certain traits unessesary

Like before the asians, it were the indians who were amazing with math

But well, say if every one had a calculator, how long before they dont see any reason to keep going with math

True some inventions make somethings that evolved useless.

You cant affect that with the starting conditions in my opnion
