In a new study published in the journal Current Biology, scientists have discovered that light skin evolved 1 million years ago in the last common ancestor of humans and chimpanzees.
The study was conducted by a team of researchers from the States of Queensland and South Africa, and it provides new insights into the evolution of human skin color. The study found that light skin evolved in the last common ancestor of humans and chimpanzees because it conferred an advantage in terms of thermoregulation.

So, if you're looking for some new and interesting research to read, be sure to check out the latest study published in Current Biology. It's sure to fascinate and intrigues you!
According to a peer-reviewed study in the prestigious journal ‘Science’, Skin color variation appears to have existed long before modern humans emerged, because some of the genetic variants the researchers discovered, coding for both light and dark skin pigmentation, were quite ancient, between 300,000 and 1 million years old. 

The color of our skin is one of the few human characteristics that is more variable,  and historically polarizing.  One of humanity's most distinctive, and stunningly variable features, is skin color.  The study of various African ethnic groups reveals that our skin's genetic history is more nuanced than previously believed.  Indeed, Skin tone has varied greatly among humans for at least the last 1,000,000 years. 
So concludes an analysis of the genetic variants associated with skin pigmentation in people from several regions of Africa. Surprisingly, The latest findings suggest that some particularly dark skin tones evolved relatively recently from paler genetic variants.  In fact, of the darker-skin gene variants, three appear to have evolved from less pigmented variants.  This means that very dark skin actually evolved from brown skin, according to the scientists.
