Crucial for many of these groups, from Suciu de Sus down to Verbicoara-Tei is the EBA Cotofeni horizon, which then evolved into Mak� and Nyirseg, as well as other related groups of the Carpathian basin. E-V13 starts basically around the time of Cotofeni, before that we have the gap from the first E-V13 to the modern main clade and all its subclades. At the time of Cotofeni we're really talking about one lineage, possibly even just one individual. So even if E-L618, early E-V13 was just a tiny, tiny minority, one individual could have been enough.
After that we see a steady growth and sudden increase around the MBA, with an enormous peak in the LBA-EIA transition (1.300-800 BC/especially 1.200-1.100 BC). That's the G�va/Channelled Ware timing.
