James Chatters (of Kennewick Man fame), in his book Ancient Encounters speculates that the genes that produced Kennewick Man also produced the Asians and Europeans. If Cord Pottery is oldest in Japan and is also found later in Europe, this may be some support for his speculation? Europeans were 'hatched' in Asia?

Or--another possibility that occurs to me--it could be that the European Cord Pottery tradition is older than previously thought and may descend from the same period as the Venus figurines, just as the Cord Pottery and Venus figurines appear together in Japan. BTW, that reminds me of something you posted a few months back:

Prehistoric Oriental 'Venus' Carved On Cliff Discovered In Ningxia

I wonder now where the Celts originated.

Cord pottery design looks awfully familiar.

"Or--another possibility that occurs to me--it could be that the European Cord Pottery tradition is older than previously thought and may descend from the same period as the Venus figurines, just as the Cord Pottery and Venus figurines appear together in Japan."

Perhaps. At some point, 12-15k years ago, the people of Japan were 'cut-off' by the rising waters from the Ice Age end.
Trading and contact by sea would be limited. So, what-ever similarities exist between the Jomon and Europeans likely occurred before the ending of the Ice Age...which would fit with the dates of the European Venus figurines, 23-25k years ago.
