I promised y'all months ago that I would keep you up-to-date on the controversy about whether the Indo-Europeans came down the west side of the Black Sea or the east side. Because I knew you'd be fascinated to know whether the Gimbutas or Renfrew theory was more likely to be true.

Forget all that kurgan horseman north of the Black Sea stuff - that came later. Giacomo over at Joust The Facts will be thrilled.
