I don't think it's nature vs nurture, but that nature nurtures us to who we are as human beings.
See, nature is extremely simple. Animals just adapt to their environment and as humans we tend to forget we are a type of animal in nature and that over the years our bodies adapted too.
Afrikans with the most melanin in our bodies to fight back the Sun's rays. White people's lack of Melanin due to their ancestors that traveled out of Afrika
(The Grimaldis) and into caves during the ice age.
For hundreds of years mutations of white skin and blue eyes and other colors came to be because of not needing melanin because where they were had little sunlight therefore no biological need for it. This goes for all other races too!
Look at it like this, we as a human species are only a canvas for whatever nature paints us to be.
