Five hundred thousand years ago a hyena was munching on the remains of one of our early human ancestors.
The human remains were found resting in a cave in the suburbs of what is now Casablanca in Morocco, an area known to be rich in fossils.More specifically, it was tucking into the thigh bone of an individual believed to belong to the prehistoric species Homo rhodesiensis,thought to be the common ancestor of both our species and the Neanderthals.
The femur bone was uncovered in a layer of sediment known to be half a million years old. It was unearthed in excavations in 1994 but only "rediscovered" over a decade later. -BBC news
I thought this was interesting because it's not everyday you hear your great great great great great great etc. ancestor could have been an ancient hyenas breakfast. I don't really know what principle this would fit in with or what it would be like in the ideal world because I really don't mind the fact that we used to be eaten. It's not like we don't eat animals and back then we were just another animal. And besides being eaten by a prehistoric hyena is a pretty cool way to go.
