Hmm I wonder if it is just an adaptation (humans mean their staples are about and it gets selected for) - or if it is something mutagenic. The fact it is the same enzyme makes me wonder.
The image of the wolf with the deer leg in its mouth and the German shepard with the pizza slice in its mouth is basically the entire tl;dr.
Good quality dog food is closer to deer leg then to pizza. Unfortunately there are too much low quality made of unbelievable junk pet food around compare to which even pizza sounds good and healthy. That prompts a lot health problems to the dogs.
Earlier quoted context omitted.

But specially made dog food has only existed for 100 years or so. Dogs evolved eating humans' food scraps.

The wild animals have the genes, the ones associated with humans have multiple copies of it.
The domestification might even imply reverse order - that the ones with the starch genes were more likely to wind up in "dog" pools - say because they were attracted to starch and got closer to humans - and thus plenty of extra copies among their descendants. Meanwhile ones without were more likely to stay away and their descendants more likely to wind up in "wolf" pools where prevalence was lower.

Feeding them scraps might be better, but 100 years ago people had a less healthy diet than today (Not really up for argument) so between scraps from the old days, scraps now, cheap dog food, expensive dog food you have to look to see how to order them.
Plus how often they eat, as long as the cheap crap is fortified and you don't over feed the dog, fine. Same as humans, eat what you want as long as it's once a day.
> This may suggest that our lineage has evolved specific adaptations to digest starch-rich foods, underlining the long and continuing importance of these staples in our diet This reminds me of the interest in keto dieting and the frustrating misunderstanding that carbs are the cause of excess weight, diabetes etc. If that were true, the whole world would be diabetic and obese, since everywhere has a staple carb.

As societies get richer and more sedentary they do get more diabetic and obese though. That’s not really due to carbs existing of course - but as we get easier access to luxury ultra rich foods it causes a lot of problems.

It's usually more of an issue with simple carbs, ie monosaccharides and disaccharides. Starch isn't one of them.
Although I follow a ketogenic diet and benefit from it I have laughed about the claims that it's somehow aligned with the needs of Paleolithic people. SO I really enjoyed this: "Unlike Neanderthals and Denisovans, who had only two diploid copies, we carry up to 20 copies of the AMY1 gene, which produces salivary amylase. "

Isn't that the opposite of what you believe? Paleolithic people were not genetically adapted to high-starch diets like we are. Ergo, a low-carb diet like keto was more natural for them.
