Confirmed being the key word - the decades-old Standard Model absolutely predicts this.

We’ve all noticed this, right? Some of it is just age, but my dad ballooned just after he married and I doubt it was a coincidence.

That’s not a very good headline. Of course they did it for food, the model was about whether they could have domesticated themselves fast enough without being forced.

I’ll have to actually look into the research; I have trouble imagining how one would model that in silico.

Edit: A link. Looks like they assumed human tolerance only effects odds of getting human food, and is (except for occasion mutants) inherited as a random point in between the mother and father’s.

I read about this just recently. It was more of an evolutionary cousin thing; dogs and wolves diverged like a million years ago, well before we were in the picture. The ones humans ran into on our way out of Africa would have been from a different subspecies, and potentially were prone to domestication from the start, while the ones that became modern wolves were confined to (now submerged) Beringia until the end of the ice age.
