It not a study. It’s a bunch of postulation and no data or experiment and based entirely on conjecture.
As is the idea that fire enabled us to boost our nutrition enabling brain growth. I have no problem with the paper in Nature, and no problem with PBN promoting it. I think they’re overreaching saying it was fermentation not fire. It may well have been both. Fire 2m years ago and fermentation more recently once we had containers to ferment things in.
That’s really the core of my point.
You could very well be right on fire / ferment and whatnot. We have so very little substantive paleontological information to go off of.
