Arm-chair opinion, but there are - just that chimpanzees/humans are a particularly bad example 'cause it happened so long ago. Once you have a common ancestor species split off into different species those species, by definition, can't share mutations between each other. Separately, chimpanzees and humans are "different", not necessarily better than each other. I don't know enough about the evolutionary history to say why but superficially they're better at tree-living and we're better at Savannah-hunting. Two different environments, so sharing mutations probably wouldn't help much.
