> We are the only animals in the animal kingdom that cooperate across genetic boundaries. Most animals don’t even cooperate. But when they do, they cooperate only in packs where they co-evolve together, and they share blood, so they have some shared interests.

Pretty certain that lots of animals co-operate. Dogs and Cats are two examples. Dogs will "take care" of your babies. (not changing diapers but primitive protection).

I thought humans used horses but it is more complicated than that when I visited a farmer. He does have a genuine relation with his horses and without co-operation the horse will throw you out of his back.

Still he is comparing different species to different races of the same specie. Not quite a fair game.
