Ladies and Gentlemen,
You may think that humans had lost their body hair while living in oceans and sees... Actually, it is a very interesting question where humans and their ancestors, respectively had survived ice ages...
I don't think that the lack of body hair and the shape of our nose are enough proof of living only in water... Our hands and feet are not webbed and we can only spend 1 or 2 minutes under water without taking breath... When human babies are born they need to breathe first of all that doesn't function in water... That's why I say that humans lived even during the ice ages on dry land and because our extremities are all supporting living on dry land... Hair on our head protects our skull and brain which is not needed in water...
How did we survive ice ages then? I guess our ancestors lived at warm places on land, for example in caves heated by volcanos... I guess our ancestors had been able to lose their body hair living at warm places, too...
Best wishes, Joseph de la Mikula and Team
