It's that age-old discussion of why people play away from home. It's been discovered that randy baboons also cheat on their partners, but astonishingly they try to cover up their affairs too - just like us (not me obviously - I'm a good girl..). This is how it works, the leader of the baboon pack has exclusive pack mating rights. The ladies who'd have the pleasure of his blue front bottom were quite vocal when mating with him, but whilst going behind his back they'd keep quiet to try to keep their betrayal secret! Not just an ugly face these baboons! I suppose it comes as no huge surprise, we are after all animals and we are all following a natural instinct of survival and reproduction. There are always evolutionary roots to our behaviour - just fascinating!
