See my comment #81 regarding a disappointed/disgraced? woman I met 30 years or more ago.
Claiming an ancient date that overturns a hypothesis requires significant evidence. If you don’t have it, than all you’re doing is speculating.
Current archeology requires a knowledge of harder sciences than years ago. Look at the OP. The lead author is a geologist in the UK. This is hard evidence against the Berengia Standstill hypothesis which has been advocated by archeogeneticists both here and in Europe.
It’s a big one to overturn. One that I never thought made much sense.
