The Right Left Divide Between Champanzes and Benobos

There's some biology with some pretty significant parallels to the right left divide going on between champanzes and benobos. The two species are our closest ancestors, so it obviously does make a tone of sense to include them in this analysis. And there is a lot of good evidence for this in a lot of different places. Am for innate variation in aggression and its correlated traits within a given species. But then it's also social behaviouris like affiliative, pro social behavior.
