But the question that I entertain isn't if they do, it's why they do. He's spent 4,000 hours observing the behavior of wild coyotes and hundreds of hours with captive wolves, coyotes and dogs. Watching them and then mixing the observational data with the neuroscience,really makes for a pretty tight story about the different emotions animals have and the evolution of these emotions. As a biologist, I say that's just not so. So for example, if you follow Charles Darwin, who said that 'the differences among species are differences in degree, rather than differences in kind.' One of the things that I think is that, because animals are just so there in the moment, that perhaps their joy is richer than human joy and their grief is deeper than human grief, and I think that is a possibility. They just don't perhaps know what’s going to happen to relieve the grief. Bekoff also said he believes animals, some of the time, know right from wrong and behave that way.
