"This data suggests that the fate of E-V13 was linked to the elite dominance of Bronze Age society. The geographic distribution of the six main branches show that E-V13 quickly spread to all parts of Europe, but was especially common in Central Europe. The only Bronze Age migration that could account for such a fast and far-reaching dispersal is that of the Proto-Indo-Europeans. At present the most consistent explanation is that E-V13 developed from E-M78 in Central or Eastern Europe during the Neolithic period, and was assimilated by the R1a and R1b Proto-Indo-Europeans around the time that they were leaving the Pontic Steppe to invade the rest of Europe.""
E-v13 was more than likely an elite haplogroup within these early PIE cultures hence the population boom.
