Did UV radiation cause those, too?
Consider these Melanesians.
They evolved curved dicks to piss on their own bellies.
Actually I'd argue for yes on that too - although I think its more a matter of heat management and UV rather than just UV.
Compare people living on the equator - who tend to be taller and thinner with dark skin thereby increasing the surface area to volume ratio to people who live in colder climes like the Inuit.
Inuit people are shorter and stouter. Their surface area is smaller compared to their volume as they wish to retain heat as much as possible.
There is growing evidence on the effect of environment on our design. Consider Homo floresiensis (known as the Hobbit). His dwarfism exactly mirrors that of other animals when cut off on small islands (for example the Maltese dwarf elephant, the pygmy hippo and so on).
