Proto-Euphratean language

Proto-Euphratean was considered by some Assyriologists (for example Samuel Noah Kramer), to be the substratum language of the people that introduced farming into Southern Iraq in the Early Ubaid period (5300-4700 BC). Dyakonov and Ardzinba identified these hypothetical languages with the Samarran culture. Rubio challenged the substratum hypothesis, arguing that there is evidence of borrowing from more than one language. This theory is now predominant in the field (Piotr Michalowski, Gerd Steiner, etc.).
