In order for life to take hold at all on a cooling planet, it had first to occur with fantastic profusion. We have a micro-glimpse of this in our little human lives: men produce infinitely more seminal fluid than is required to build a human family, and are tortured—not completely unpleasantly—by the urgent need to spread it all over the place or otherwise get rid of it. (Religions have needlessly added to the torture by condemning various simple means of relieving this presumably “designed” pressure.)
