Selective breeding in Russia domesticated Foxes over a 50 year program and could selection be...

I raise goats. One of my cull factors is "milk stand" temperament. Once I wean the kids from their does, I continue to provide milk to doelings and intact bucklings on appropriate sized milking stands. Those that don't figure it out quickly, get sold. I don't have time to waste on milking does that "fight" getting on the stand. Routine medical checks and procedures and hoof trimming is far easier when they are in a stand. 10 goat generations ago about 40% of the kids were culled from the herd because of temperament, now its less than 5%. (I have other reasons I cull). The majority of the problem kids come from older generations.

as far as the AI question goes, even unsupervised learning inGenetic Algorithms (GAs), Artificial Neural Netowrks (ANNs), and Expert Systems (ESs) all involve selective culling of aberrent connections, combinations, or learning patterns. in a sense, we ALWAYS cull the herd to produce the desired result. in short, the question exhibits the ignorance of the author.

Interesting, but I suspect that they will succeed no better than we have succeeded in domesticating cats. The unusual bond between humans and dogs is based on the simple fact that dogs are pack animals. Humans used their instinct to bond with other dogs (wolves originally) to bond with humans. Cats and foxes have not such bonding instinct. Neither are pack animals.
