bullethead
Of the hard cast variety
This strikes me as a convenient observation. WE could also say that wild turkeys are engaging in religious rituals, but the reality is they do that sorta thing when they are looking for love. This is a primitive instinct directly related to the survival of the species. Not sure about the chimps, but, I am thinking it's one of those "can't be this so must be this" type things......at first thought. I am open to reading more.
And that certainly is easy to conclude as you and I have never observed a single chimp in the wild let alone have spent years observing a family of chimps in the wild.
Fast foward a short 5 million years later and two of those chimps, one called jb0704 and another called bullethead are typing to each other about a couple of bonobos that hold hands and walk around a crooked stick every full moon...
