New Jewish Genetics Paper, 9/9/14

Another one about the tribe.

You can read the whole thing yourself, but I see the main points (none of which are new) as:

1. Ashkenazi Jews (AJs) are a highly inbred population, derived from a severe bottleneck.

2. AJs are a more or less even mix of modern Middle Easterners and Europeans.

3. The Khazar theory is once again undermined.

4. Perhaps most controversially, the authors believe that Europeans derive most of their ancestry from Neolithic Near Eastern farmers, not (Paleolithic) hunter gatherers.  

Point #1 underscores why extreme ethnocentrism, dual morality, and ethnic paranoia are particularly adaptive for Jews.
