There is a LOT of work that went into trying to figure out why.
Seems the things scientists were expecting weren’t the cases sometimes.
I agree that when meat was plentiful they dabbled
And then some said “Hey, why don’t we grow a lot of this in case it gets harder to find meat”

Our ancestors had 200cc more brain volume ten thousand years ago on average vs today.
The brain and body thrive on meat and fat. Whomever thought it would be better to scratch dirt for ten hours a day in repetitive and laborsome movements rather than running and strategizing and stalking and making tools on the fly must have been the AOC of the paleo world.
