We recently discovered that Hyenas were one of our primary predators well before we figured out tools and fire. There are archaeological sites that have thousands of human skeletons that were clearly eaten by hyenas. Mostly children, IIRC.
I would surmise that some of us have completely overwritten our basic instincts. Hyenas would also be friend shaped, but somehow I’m reasonably certain that your and my ancestors would disagree.
I dunno. I’ve seen hyenas in the zoo and I did not get the same feeling towards them. Lions are also rather intimidating once it’s just a bit of wire and a slightly too far jump between you. Wolves and coyotes though, they make me want to do the whole domestication thing all over again.
Also foxes, don’t forget about foxes. Very friend shaped.
