Turns out most of them do. How many breeds of dog now have hip dysplasia as a breed? Red hair in humans leads to lower pain tolerance and greater risk of sun damage to the skin. Bacterial resistance tends to make organisms that don't do as well under ideal conditions, though they can survive extremes well.
