A major motivator for the investigators is the historical lack of diversity in genetics research. For example, the first major study on the genetics of skin tone diversity in Africa occurred only recently. Latin Americans are similarly underrepresented in genetics research, particularly in pigmentation research.
“[This is a] rare example of intense, ongoing adaptation in recent human history and is the first known example of adaptive gene flow at a pigmentation locus in humans,” the authors wrote in their report. The lead author, Meng Lin, is a post-doctoral researcher in genetics at the University of Southern California.
A Penn-led team identified new genes associated with skin colour variations. Their study of more than 2,000 Africans from diverse ethnic backgrounds sheds light on ancient human migrations, the biology of skin pigmentation, and health and disease risks. (Photos: Alessia Ranciaro and Simon Thompson)
