    It’s survival of the genetic line that reproduces enough to stay alive. The weird shit is often related to path dependence, or is just not enough of a detriment to affect evolutionary outcomes.

      Horses must have plenty of good evolutionary traits, because even without human breeding they’re very successful creatures. I guess they don’t reproduce quickly, so that isn’t it. I guess they can’t shrug off injuries. They must be really good at not getting caught by predators, so they live enough to have at least a couple of foals.

        I mean, I think they also evolved on steppes and open plains, where running fast is not too often super dangerous, so breaking a leg is not common enough to counter balance the advantages of being fast.
