“An experiment using black stones in place of some of the cheese also saw wolves choosing the larger amount of cheese than the dogs. Experts said it is possible that, due to domestication, dogs possess a weaker ability to mentally represent and discriminate quantities in comparison to wolves.”
Wolves have to work to survive. Domestic animals become dependent.
Made me think of the welfare system and the dumbing down of some.
I would describe it as dogs being adopted to work with humans. For most of human history, different breed of dogs served useful purposes. Good luck trying to get a wolf to herd sheep. :0
