A social history question ...

I saw an article in SR or one of the others that showed the area around China was populated by a group of hominids who left the african plains before the neandertals and homo sapiens who populated europe and the near east.

For years I have been trying to figure out how went where and did what starting with our very beginnings in the African bush. We see what we thought was a first group of neadertals and hominids migrating from northern africa into europe then a second group after the mini ice-age who went across europe as well as across northern africa and up into the fertile crescent. We suppose that those northerners were hunter-gatherers who bunked with the surviving neandertals and a few denisovans and slowly crept across europe and finally crossed the hindu kush to meet farmers from the fertile crescent in the indus valley.

I know this is rather abbreviated but I am trying to see the cultural influence on the religions involved. It's relatively easy to see the vedas developing from belief rituals ranging from the British Isles to the Scandinavian country through Europe and into SE Asia over the Kush. You see a little Confucianism and some Lao Tzu influences but generally China is isolated and the reason for that has always bewildered me.

Now with China being populated by another group of homo erectii we can see why. maybe. Their social evolution was essentially isolated by the vast expanse of mongolia and the himalayas. That also explains many of the physical differences we see in the eastern asian populace compared to europeans and middle easterners.

It also supports views that the monotheistic beliefs of the second groups have similar origins and are distinct from those the evolved in China.

Please offer up any thoughts on the path these thoughts are taking me. Be as brutal as you want. I appreciate any input.
