If you think this is inconceivably lopsided, wait until you see Elephant Seals mating on the shores of Point Reyes. Those bulls have one hell of a job come mating season.

But I'm pretty sure evolution still wants heaps of genetically diverse males to come out and compete in the reproductive lottery. Even if only a few of them win, they're the .. well, winners, genetically speaking.

With fewer participating at an existence level, you'd have would-be losers succeeding for lack of competition.
