Chimps share a stone throwing ritual belief, even when alone

These filmed chimpanzees share a symbolic behaviour.  They throw stones in a ceremonial way at a specific tree.  They throw these stones when no other chimp can see them.  The camera trap shows a succession of adult male and female chimps choosing a stone, looking around, then hucking it at the trunk and heading off.  Source: Scientific American
