>What do we mean by "the date of PIE"? 7-8k BCE is much too early for the diaspora. If memory serves, Sherratt dates the appearance of (ritual?) ard-marks under European barrows to 3500, give or take a century. The diaspora must have followed the ard (i.e. light plough), *h2arh3-trom. This is what makes 3-4k BCE reasonable for the breakup of PIE.
> PIE has only a few words related to agriculture, domestication, and metals which, IMO, points to a late paleolithic/early neolithic date. So 7-8k BC seems reasonable.
