This is so exciting. This is far earlier than we’d previously expected such complex behavior. Here we are debating how deliberately Neanderthals were when they left bodies in caves and whether that was a form of burial. Here’s some other species much earlier fashioning some sort of complex structure.
The only reason we don’t have lots more of the evidence of complex thought is because biological material rarely persists, thus an image of lunks using only stone tools has persisted until now. So cool.
