Yamanya were NOT the Proto-Indo Europeans

The GAC is documented in Central and Eastern Europe, from the Elbe to the middle Dnieper, around 5400–4800 BP. It plays a crucial role in this debate because it has been argued to be associated with the first Indo-European migrations based on its burial rituals, including burial of livestock, usage of domestic horse, and presence of amber sun-disks Gimbutas argued that when the Kurgan culture expanded from its homeland in the steppe and forest-steppe of Ukraine and South Russia, it did so in three waves, thus leading to the diffusion of the IE languages (see electronic supplementary material, figure S1). The GAC people are regarded by Gimbutas as part of the first wave, associated with the spread of the Yamna culture from the Pontic region to the Danube basin and the Balkans, between 5100 and 4900 BP . If Gimbutas' theory is correct, the people of the GAC should have Yamna related admixture, as well as genetic affinity to the populations associated with the later, Bell Beaker culture, documented in many areas of Europe 4800 to 3800 BP.
