The silliness – www.independent.co.uk/news/science/mysterious-chimpanzee-behaviour-could-be-sacred-rituals-and-show-that-chimps-believe-in-god-a6911301.html

Personally I think all this ‘religion’ talk is nonsense. There could be many other reasons for this behavior. I’d go with territory marking since chimps are EXTREMELY territorial and also as a show of dominance. Chimps love a bit of ‘dominance display.’
Actually, apes bloody love war! Go on Koba! Throw some rocks at him!
Obviously military training for the coming Ape-ocalypse.
