Anthropological studies on the Tsova-Tush found them to be somewhere in between the Chechen-origin Kists and the Chagma-Tush of the region, but significantly closer to the Chagma-Tush [REF].
Theories regarding the origin of the Chagma Tush all include descent from Georgian tribes (possibly pagans fleeing Christianization in the 4th century CE), but variously involve influence or admixture from South Caucasian Nakh, Dagestani peoples, or none [REF].
