Some new genetic studies suggest that recent erosion of human population structure might not be as important as previously thought, and overall genetic structure of human populations may not change with the immigration events and thus in the Azerbaijanis' case; the Azeris of the Azerbaijan Republic most of all genetically resemble to other Caucasian people like Armenians, and people the Azarbaijan region of Iran to other Iranians.
一些新的遗传研究表明现在的人类人口结构的紊乱可能没有和以前的思想一样重要，人类人口的全体遗传结构可能不会随着移民事件而改变，譬如在阿塞拜疆人中的例子，阿塞拜疆共和国的阿塞人的大部分基因与其他的高加索人相似比如亚美尼亚人，且在伊朗境内的阿塞拜疆区的人与其他伊朗人相似。
