This passage is from Nina G. Jablonski's essay "The Naked Truth: Why Humans Have No Fur":

Another clue to when hominids evolved naked skin has come from investigations into the genetics of skin color. In an ingenious study published in 2004, Alan R. Rogers of the University of Utah and his colleagues examined sequences of the human MC1R gene, which is among the genes responsible for producing skin pigmentation. The team showed that a specific gene variant always found in Africans with dark pigmentation originated as many as 1.2 million years ago. Early human ancestors are believed to have had pinkish skin covered with black fur, much as chimpanzees do, so the evolution of permanently dark skin was presumably a requisite evolutionary follow-up to the loss of our sun-shielding body hair. Rogers’s estimate thus provides a minimum age for the dawn of nakedness.

Before reading this passage, I believed that black skin was the ground from which all other types of skin grew. That way of thinking is now a thing of the past.

Speaking of black skin, which comes from (or with) white skin:

US neo-soul singer Erykah Badu has been charged with disorderly conduct for stripping naked on a street among pedestrians for her music video shoot.

She ended by re-enacting receiving a fatal gunshot to the head at the spot in Dallas where President John F Kennedy was assassinated in 1963.

Sergeant Warren Mitchell said Badu was charged after a witness offered a sworn statement to police on Thursday.

The singer, who was born in Dallas, performed a walking striptease in front of tourists and pedestrians during the shoot in Dealey Plaza on 13 March for her video for the song "Window Seat."

The words in Tricky's "Tricky Kid" come to mind: "I'm naked and famous."
