Aquatic mammals with hair usually have little hair that does not affect much or hair of types which keep the skin dry. Hominids do not have the type of hair which can keep the skin dry.
My theory has long been that fungal infections drove hairlessness. Features don't evolve to do something. Lethal features kill off those without a less lethal feature - such as hairlessness. but it's still conjecture.
Why are some littoral beasts fur covered (i.e. beavers) and others nearly naked (elephants, rhinos, hippos)?
I do think it has something to do with lethality during infancy.
