Just learned that Prime Minister Naoto Kan of Japan is married to his first cousin: http://blog.foreignpolicy.com/posts/2010/06/08/japans_prime_minister_is_married_to_his_first_cousin
Just wondering, is that necessarily true? Statistical probability aside, isn’t there tremendous shade variation among full-blooded Africans anyway?
One of my great-grandfathers (father of my paternal grandmother) married the sister of my paternal grandfather. They had one child, so that side of the family tree is a bit knotted (I’m my own 2nd cousin or uncle or something).
