I didn’t bother to read all of the article. Did he find Spice in Andalusia, by any chance? That’s how I understand the mechanism has to work. No spice, no shared ancestral memories. And only men can share the memories of all of his ancestors - women can only share their mothers’.
There was a trilogy of books (Clan of the Cave Bear, I think was the name of the first, that were pretty good until the 2nd or 3rd in the series got bogged down primarily in romance) in which a young homo-sapien girl was adopted by a tribe of neanderthals. The neanderthals had transgenerational memories. So the idea can be an entertaining element in science fiction/fantasy.
