[Where he talks about occipital bun, in Swedish equivalent to "genius bump", and two more:]

Ah, genie-knölen .... an argument for Japheth's wife having Neanderthal roots, right?

(If she was Sethite / Cro-Magnon mother and Neanderthal father, she transmitted neither Neanrthal mitichondrial DNA, since her mother wasn't Neanderthal, nor Neanderthal Y chromosome, since women can't transmit anything except X chromosomes on that pair - and both are extinct).

That leaves last pure Neanderthals = last pre-Flood Europeans. Or carbon date for Noah's Flood = "40 000 BP" (non extant date and implies lower carbon 14 content).

By the way - Neanderthals left no cave paintings to us.

Could Flood have dissolved colours from the walls, so any cave painting is post-Flood, if preserved?

Lived side by side with "Homo sapiens" (after that wise man Noah who went aboard an Ark right?) ... well, Sethites may not have been majority population in Europe by any means, but there were no natural barriers to them coming and visit here, and leaving traces (including those mix race brothers in a cave in Roumania).
