The Basques may have formed out of several groups. Around 4,000 ybp, the Yamnaya invaded them killing of most males and with that ending the tradition of oral translation.
In other words: Basques themselves are unaware of their origin today.
The language however remained as the offspring of Proto-Basque women and Yamnaya men was raised by the Proto-Basque women.
Y-DNA G2a indicates ancestry among the Black Sea tribes, possibly Armenians and Georgians. There are supposedly language similarities between Armenians and Basques today. The Proto-Basques lacked R1b completely meaning though from the Black Sea region, they were not of the same ancestry as the Yamnaya people.
Were the original Basques equally high in rh negative blood or higher or was it introduced by the Yamnaya invasions?
