`How do you explain the other animals that swim and dive, but that still
`have hair? There are many mammals that spend varying amounts of time in
`the water, but yet have hair. Why wouldn't the same selective advantage
`in less body hair apply to them?
I don't think you'll find any with hair. Fur, they have. Considerably
different. Fur is a definite advantage for an aquatic animal,
whereas hair is probably just a nuisance, and possibly a serious
liability. It's not thick enough to insulate, nor oily enough
to shed water.
