There is no way anyone can convince me that all the worlds civilizations came from one area of Africa.
Re: “There is no way anyone can convince me that all the worlds civilizations came from one area of Africa.”
As I understand the hypothesis, almost 100% of human beings currently have mitochondrial DNA that can be traced back 60,000 years to the same mother.
Since there is clear evidence that Humans migrated out of Africa at least 100,000 years ago (and possibly 180,000 years ago), that theory has never made sense to me, either.
Also, there is significant evidence that Neanderthals evolved outside of Africa, and there is no question that almost all modern European and Asian humans have some Neanderthal DNA.
When you go and look at particular DNA talk, there are different waves of groups ‘walking out’ of Africa. Tribe-A goes in this era, Tribe-B goes in this era, etc. Each likely affected by changing weather, drought, and hunting practices.
In our way to view Africa by today’s standards, we fail to often grasp the fact that 150,000 years ago....in some area the size of Iowa, there might have only been four tribal groups (fifteen to thirty residents each), and they might not ever bump into each other. As the tribal units continued...they ‘married’ into each other and evolutionary situations might have been affected by this.
