Incidentally, most ethologists prefer to use baboons as ways to deduce human behavior. While they're far more distantly related to us than great apes, or even most other Old World Monkeys, they live in organizations and environments roughly analogous to those of our prehistoric ancestors.
there is just one problem, animals are on the whole incapable of deception and manipulation, the animals that kiss and make up are genuine, humans are a whole different matter......has this person never read about the Trojan Horse
secondly with many other species of animals, you have loyalty to your pack but not others outside your pack and certainly not outside your species and it's killed or be killed, in other words they are as territorial and tribal as humans are, after all we are mammals....
