The problem is, "What we do when two strain of the human race evolve in 
divergent ways that are mutually exclusive?".

What we see as "Clash of Civilizations" could be the natural selection 
and the reactions of different strains of the human species to the 
radically changing habitats?

What is the survival fitness of people living in cities if they are 
unable or less able to learn to read, write, compute, etc.? Or with too 
much violence prone? Or not enough violence prone? Or without the 
ability to stay focused for long times?

For example, I remember that US army instructors wrote that is very 
difficult, if not impossible, to train an Arab to be a skilled sniper 
(not only able to shoot right, but also to wait, wait and wait).

The recent study about urbanized and country dwellers of the same 
African tribe, where the urbanized have much less success of the pastors 
because they both have the same gene coding for hyperactivity.

With the majority of the world population living now in cities, the 
natural selection will favour people more able to live in high density 
settings and with all the skills and ability needed to be successful in 
a city and not in the bush or in the desert or in the ice.
