One can imagine, for example, a close association between some groups of wolves and humans, with the former existing in a symbiotic relationship with nomadic bands.

Genetics of aggression

The researchers analysed single-letter differences in the genome called single nucleotide polymorphisms, longer segments of DNA shared between different Jewish groups, as well as deleted or duplicated stretches of DNA called copy-number variants.

This has often been interpreted to the effect that they are remnants of the original expansion from Africa some 70, years ago.

Recent reports have reaffirmed that the AJ population has a common Middle Eastern origin with other Jewish Diaspora populations, but also suggest that the AJ population, compared with other Jews, has had the most European admixture. Funny, We Don't Look Jewish.
