The expansion of agriculture from the Middle East would have diffused three language families: Indo-European languages toward Europe, Dravidian languages toward Pakistan and India, and Afroasiatic languages toward the Arabian Peninsula and North Africa. Reacting to criticism, Renfrew revised his proposal to the effect of taking a pronounced Indo-Hittite position. Renfrew's revised views place only Pre-Proto-Indo-European in the 7th millennium BC in Anatolia, proposing as the homeland of Proto-Indo-European proper the Balkans around 5000 BC, which he explicitly identified as the Old European culture, proposed by Marija Gimbutas. He thus still locates the original source of the Indo-European languages in Anatolia around 7000 BC.
