"Mallory (1997) agrees that there is solid evidence in both European and Asiatic stocks for Proto-Indo-European cereals, as well as the agricultural terminology required to process them. He notes that "while the economic emphasis of the immediate ancestors of the Indo-Iranians may have been towards pastoralism there is good evidence that they too are derived from a mixed agricultural population" (236-237)"
