The secret of pale skin.

Scientists at the University of Oslo have deduced that developing a pale skin depends on how you get your daily quota of Vitamin D.

 

As you all know, we get our Vitamin D from sunlight and from our food. Apparently, a light skin enables the human body to create its own Vitamin D from sunlight.

 

"A sudden change of diet around this time, attributed to the move away from hunter-gathering into agriculture, is believed to have led to a major shift in skin tone in order to atone for the lack of Vitamin D. Food which is farmed is notably lacking in the vitamin; but the human body can create its own vitamin D from sunlight, with paler skin working best for the purpose.

 

Scientists at the University of Oslo believe this change in diet may have led to our dark-skinned ancestors evolving paler skin to overcome this problem".
