At the beginning of Dune, someone differentiates humans from animals like this: > You've heard of animals chewing off a leg to escape a trap? There's an animal kind of trick. A human would remain in the trap, endure the pain, feigning death that he might kill the trapper and remove a threat to his kind. The idea is recognizable, at least. It's antelope individually scattering from a cheetah, rather than forming a tight group that wouldn't be attacked a second time. But it's sad, and kind of funny, just how wrong it is to draw that line at 'humans'. Gorillas disarm traps instead of avoiding them. Elephants defend their friends, even across species, and bury their dead. Dolphins proactively kill sharks, and hold injured dolphins - or humans - at the surface to breath. Even octopuses, not usually understood as a social species, display clear theory of mind. It's not just the endless redefinition of "tool use" that feels like hubris anymore. Just about everything we consider deeply meaningful, emotion and intellect and teaching and even ritual, is not a uniquely human experience.
