Iran Attacked Its Arab Neighbors -- Their DNA Explains Why

[Warpy]

Interesting factoids about stark cultural differences backed up by largely unmixed DNA, although both populations are mixed. They are simpkly distinct from each other.

While this is interesting stuff, I think Iran's reluctance to take on Turkey and Azerbaijan is rootd more in history than genetic or cultural separation. The pre British Empire history of the region tells of multiple wars fought between the Turks and Persuans, each one pretty much curb stomping the other and nearly ruining themselves in the process. I think that's the reason Iran has so far limited itself to strictly Arab nations plus Israel. They don't want to provoke the Turks if they don't have to.

1. Interesting...

... and it appears to support something I read a few years ago: That Persians – now Iranians – are of Caucasian heritage, not Arabic. Their only similarities are religious, and even then, not the same sects; Iran is Sunni, the Arabs, largely Shiite. But, as in all things religious, the differences are enough of an excuse for countless wars.
If the species doesn't consume itself in a nuclear holocaust, humanity might someday abandon religion altogether, finally embrace our differences, rather than kill each other over them, and mega-church charlatans will be remembered as a failed evolutionary hiccup, and speaking in tongues will be a punchline.
