^ Wow, Neolithic China had pot-heads :D  Yeah, blue eyed Caucasian ones who spoke a language closely related to Celtic :D   Personally, I think they were Aryan, Proto-Celts. These mysterious people pre-date known Celtic culture in Europe, yet share a very similar language, very similar clothing(such as plaid and conical shaped Druid's hats/witch's hats) and similar artwork. Aryans are said to have came into Europe from the east..from Central Asia and the Caucasus, hence the term-Caucasian/Caucasoid.
