A chart where one can see what is the difference between Nakh ( Chechen and Ingush ) and other Daghestani people.
They have lower Steppe than Daghestani !
They have higher CHG than Daghestani.
And more interestingly they have Anatolian Neo ancestry which Daghestani lack ( except Udins who are a special case )
Interestingly this fits well into Strabo's recount about the origins of Gargareans from Pontic region. Also the high level of J2-CTS900 which is the result of founder effects point toward a western region. Daghestani people for example do not have CTS900. It must be noted that I don't mean the origin of Nakh languages. Because they can be local but the extra non Nakh migrants could have been assimilated into locals creating the Proto - Nakh community that expanded 2000 years ago.
