A Baboon’s Life

Why are the prime-age males so aggressive to the deposed ruling class? Are they afraid that the old guys may rise again? Do they get an ugly thrill from getting away with it? It is impossible, of course, to say what is going on in their heads. My studies indicate, though, that the new generation doesn’t much care who the aged animal is, so long as he was once high ranking.

One might expect what goes around to come around, that males who were particularly brutal in their prime should be the ones most subject to indignities. But I did not observe this pattern. The brutalizing of elderly males who remained in the troop was independent of how aggressively they had behaved in their heyday. All that seemed to matter was that they had once been dominant and that they no longer were.

Even against this grim backdrop, more than half of aging males did not leave their bands. Instead, they finished their lives in the troops where they suffered this mistreatment. My data suggest that they were sustained through their later years by simple friendship ­ friendship offered not by other males, but by females in the troop.
