This object is a record of the eater and the eaten, the hungry tooth-marks visible on what must have been a raw rib-bone. Predator and prey was one of the kick-starters of the evolution of animal brains, as opposed to simple signalling organisms. The desire for self-preservation instincts happens when things stopped being satisfied with munching on the same microbial mat and started eating each other. If this was a fox its predatory instincts didn’t get a chance to kick in with this bone, which looks like it’s a left over from a human. I wonder if the wild scavengers such as foxes and pigeons will start to develop different diseases now that our leftovers have become more processed.
