A virtual Round Table celebrating Marija Gimbutas (1921–1994), UNESCO's 2021 Centennial honoree. Marija Gimbutas was a professor of archaeology at UCLA and internationally renowned for her study of the arrival of the Proto-Indo-European languages and culture in Europe. One of her most original (and controversial) contributions has been validated recently by aDNA: the Kurgan Hypothesis and the arrival into Europe of the Proto-Indo-European speakers around 3500 BC. Introduced by Ernestine S. Elster, the participants include James Mallory, David Anthony, and Dorcas Brown with Willeke Wendrich as moderator.

Schrader assumed that the original homeland of the Indo-Europeans was in the steppes north of the Black Sea, on the Caspian Sea, and on the Aral Sea, an area referred to as the Pontic–Caspian steppe, where wild horses were a native species. Schrader's theory would ultimately serve as the basis of Marija Gimbutas' Kurgan theory.[3]
