London, January 21. Specialists find new genetic variations related to skin color afterwards evaluating pigmentation in more than six thousand Latin Americans with a mixture of Native American, European and African ancestry, reports the journal Nature Commnications today.

Research conducted at University College London, allows identification of five new regions related to the color of the skin, eyes, and hair.


He pointed out that clear skin variations among people in Eurasia developed independently of different genetic backgrounds.

Geneticists leave it strongly that Native Americans are genetically related to East Asians who settled around 20,000 years ago, through migration from Siberia to North America.

They observe one important variations in the MFSD12 gene which manifests itself uniquely in East Asia and Native Americans.

The work shows that brighter skin tones evolved independently in Europe and East Asia, while the gene under strong natural selection in East Asia, may be an adaptation to changes in sunlight and ultraviolet radiation.

Dr. Kaustubh Adhikari, from the Institute of Genetics at the university, said the findings explain human evolution and report understanding genetic risk factors for conditions such as skin cancer.
