When there is now a proven incident in which a wild orangutan used a non-food plant to heal a wound, we need to stop being so precious about early technology. There’s a much richer continuum between our forebears and us, and I wish our cousin species were still around to prove it.
This is an obvious logical conclusion one must draw from the theory of evolution, yet human exceptionalists have continued to insist that there's some meaningful difference between us and other animals.
