Why Dogs Smile & Chimpanzees Cry

Although I am coming late to the party, I would like to add another reply to the first posting.

It's true that ordinary people, most of us, do know without a doubt that animals have emotions. But surely you know that science was long hampered, and still is in many quarters, by the denial of emotions (and of any mental life at all, in fact) to nonhuman animals--and by the refusal to discuss or publicly acknowledge this fact. Hence the video is still plenty useful. Its measured tone, exceptional footage of compassionate and other behavior by a myriad of species, and revelations of a variety of emotions (and their evolutionary basis) is, in fact, priceless to those of us who would like to counter that trend. At least I've found it so for college students who find themselves unsure and confused about what's going on with animals other than the ones they're most familiar with.

That said, I do appreciate your objection to referring to emotions shared by many species as "human." Someday I hope that many will see the arrogance and inaccuracy of that usage. But one must consider one's audience--and that usage often gets a point across to a popular audience.
