    This only holds if the alpha males succeed in preventing the other
    males from copulating. I don't know of any cases where that's true.
    The most recent exposure I've had to harem-keeping mammals was a visit
    to see the elephant seals at Aņo Nuevo 3 years ago.

    The alphas recruit betas to help police the harem. When the alpha is
    busy defending his claim to being the biggest and meanest, one of the
    betas will occasionally wander off behind a dune to take advantage of
    the distraction. I'm sure I've heard the same about harem-keeping
    apes. It's hard to imagine any other evolutionary outcome.
