Wow, a great START to an article. Where's the REST of it?!?

What exactly will it mean if,scientifically and/or genetically,if a valid proof of the "why" in these variable tribal features is found? What can a solution to this quest mean for the inhabitants,and further,could the continued research and findings have a global interest for all! Come on folks,open some ideas.Ideas as possibilities are most likely all we have at this point.

The key here is the fact that one man fathered so many children, and left his stamp on them. There is a family here in town that you can know right away that they are related, they all look the same from the nose up, and they have a distinctive forehead. It all came from the "grandpa" of the family. There are four generations of them. Is this evolution in action?

It took a real genius to figure out that if one man is the father of most of a group of people, then most of the group will look like him! What kind of a fool would fund this "research"?

"Culture may trigger rapid evolution of various human features, suggests new research..."

So can we expect to see new generations growing up with tilted necks to accommodate holding cell phones without hands; while other youngsters may develop low hanging buttocks to fit into their baggy pants?

This is so dumb. Doesn't take a genius to figure out that natural selection and the evolution of humans is determined by the intercircle mating happening within countries, states, or even small tribes.

Very interesting study. Reminds me of the ancient Aryan cultural principles.
