He told UPI that he found, “My female line goes back to Northern Nigeria, the land of the Hausa tribe. I then went to Nigeria and talked to people and learned a lot about the Hausa’s culture and tradition. That gave me sense about who I am. In a way, it grounded me.”
“Two people there looked like cousins I have — they even behaved like them!” Kittles laughed. [my emphasis -r]
The human mind is great at making connections and the geneticist in question might not have noticed the similarity of these Hausa to his cousins in physique & personality if he did not already know he had a blood tie to these people-even a distant one. On the other hand-we are often likely to associate mannerisms & behavior to environmental influences, but we should not neglect the importance of genetics on our behavioral patterns, especially when lower level instincts help form higher complexity emergent tendencies.
