QUOTE (from the article+)
Hare says domesticated dogs" ability to solve social problems might have emerged once the brain systems mediating fear were altered -- and the same thing may have occurred in human evolution. Chimps, he says, are constrained in solving cooperative problems by their impulse to fear more dominant individuals and behave aggressively toward more subordinate ones.


What about the fact that dogs may have over 1000 times the smelling power than that of humans or chimps?

So, the dogs probably could smell the hidden food, to which direction it was pointed or “communicated”!? Any control experiments done to rule out this possibility!?
