I don’t think they’re saying that humans literally couldn’t be artificially selected to exhibit certain traits so much as they’re saying that even when enslaved people don’t play along with their captors whims like dogs do. You can’t breed humans the way you would a dog because they won’t put up with it and any project trying to force that would necessarily take a lot longer because people take way longer to reach sexual maturity than dogs.
The canine genome is extremely varied and flexible, much more than many other animals and humans, and dogs live much shorter lives and reach sexual maturity relatively quickly.
Why does that work on dogs BTW, do you know? Always wondered
Thousands of years of artificial breeding to select for certain traits
