 Well, male coalitions in lions are often siblings. And one of the great things about lions is they're a social species. The female lion is the only female cat that will really tolerate other adult females in her territory. They're very affectionate with each other. They often breed together, give birth at about the same time, and then they rear their cubs together. And so within that system, you often have a number of males growing up from cubhood through adolescence.
