I think the novelty here is that this was the same group which underwent a schism of sorts, and over the course of relatively few years became two completely separate groups antagonistic to each other.
edit: I'm rate-limited, so here's my answer to your comment of:
> I remember watching a nature documentary many years ago with exactly that scenario. The original group killed all the splitters.
Yeah, you're right. You probably remember this: https://en.wikipedia.org/wiki/Gombe_Chimpanzee_War
It does seem like a very similar scenario, so now I'm confused.
