Why do we have flat teeth, long hair on our heads, finger nails that are not very durable. Just to name the flaws that are apparent to me right off.
It seem that we were designed to exist in almost any environment. Almost like we were chosen to have dominion over the air , land , and water. We have even built cities underground. No water monkey theory , or any evolutionary theory can explain this trait of humans.
I almost bought the Idea, but I couldn't picture humans living on shorelines diving into the water to catch food , then bringing it back to shore to cook it, in order to feed his/her naked family.
