That may be true by definition, if your definition is that superior groups eventually dominate, but that's of course just tautology.
However, depending on how you define "superior", for example "more intelligent and honest", or "more compassionate and fairer", could be what most people have in mind, then that may not be true at all. In human societies, throughout history, it's likely that who dominates is actually the most brutal and reckless, up to a point where people actually become accountable for their actions.
