There is strong evidence for causal connections between the Near-Eastern Neolithic and that further east, up to the Indus Valley.[13] There are several lines of evidence that support the idea of connection between the Neolithic in the Near East and in the Indian subcontinent.[13] The prehistoric site of Mehrgarh in Baluchistan (modern Pakistan) is the earliest Neolithic site in the north-west Indian subcontinent, dated as early as 8500 BCE.[13] Neolithic domesticated crops in Mehrgarh include more than barley and a small amount of wheat.
