The Bible was/is a fantastic history written by extremely intelligent and dedicated men who were more interested in the moral evolution of mankind than they were the factual geologic and genetic movements about which no knowledge existed then, or for the next 6000 years.


The Bible doesn't say that the Earth is 6,000 years old. Some people have inferred it be that age by calculating the ages of Adam's decedents. The vast majority of Christians do not believe this to be the case, but those zealots and atheists go at each other over it. Neither side see the ridiculousness of the debate.

Homo sapiens started in Africa and began migrating out to different environments. Natural selection began to take place over many years, leading to different expression of traits that were most likely to succeed.

In colder environments, humans had to find shelter and form larger social networks different from clans. This led to skill differentiation and primitive agriculture.

So my theory is that migration and the encountering of different environments forced natural selection in humans...
