Whatever the rights and wrongs of the Israel-Palestine issue, the issue itself is clearly not about blood but about culture. There are many on both
sides who would disagree, but we need not listen to them; such ideas are antiquated, irrational and always more or less racist in origin.
Two thousand years, or a hundred generations, ago, you had – assuming zero interbreeding, which in practice could never happen – 2^100 ancestors
alive on Earth. Now 2^100 = 1.2676506 × 10^30. That's right: a number with thirty zeros in it, far larger than the number of people that have ever
lived. Apart from showing that kissing cousins are commoner than you thought, what does this tell us?
It confirms that while population genetics can help us trace a few elements of group ancestry, as individuals we're all hopeless mongrels and nobody
is 'pure' or even 'mostly' anything. Social groups – call them tribes, nations, races or what you will – are defined not by genes but by such
things as language, custom, ritual, art and artisanship.
Conclusion: this study has no implications for Palestine, unless somebody creates them by turning it into a bone of contention. It just means that
Western European Jews interbred a lot. Which we knew already.
Short interesting article on ancestry and cousinage. Not necessarily the last scientific
word on the subject, though
