these researchers had their dogs and wolves treated identically, and concluded that "even after being raised by humans, wolves simply do not see humans as potential social partners."
but my interpretation is that they learned that wolves, after being raised by humans as if they were dogs, do not see humans as potential social partners. and this distinction matters, because my family's pet dog/wolf saw us all as his subordinates, until we learned the different way to act around a wolf.
if you show a wolf tons and tons of affection, like it was a dog, it thinks you're trying to kiss its ass and take a subordinate position to it.
all these researchers really learned here, in my opinion, was that if you communicate to a wolf that you are not to be taken seriously as a partner, it will not take you seriously as a partner.
I think the possibility absolutely remains open that researchers who had bothered to do their homework first might be able to produce results where the wolves looked to the humans for help just as often as the dogs did.
if you baby a wolf in the way that we baby dogs in 2015, you are probably not creating an entirely realistic simulation of the context within which wolves and humans first began collaborating.
