The ancestors of the Nakh peoples are thought to have populated the Central Caucasus around 10000–8000 BCE. This colonization is thought by many (including E. Veidenbaum, who cites similarities with later structures to propose continuity) to represent the whole Eastern Caucasian language family, though this is not universally agreed upon. The proto-language that is thought to be the ancestor of all Eastern Caucasian (“Alarodian”) languages, in fact, has words for concepts such as the wheel, so it is thought that the region had intimate links to the Fertile Crescent (many scholars supporting the thesis that the Eastern Caucasians originally came from the Northern Fertile Crescent, and backing this up with linguistic affinities of the Urartian and Hurrian language to the Northeast Caucasus). According to Johanna Nichols "[t]he Nakh–Dagestanian languages are the closest thing we have to a direct continuation of the cultural and linguistic community that gave rise to Western civilisation."
