Abstract
Human Evolution Skin color varies among human populations and is thought to be under selection, with light skin maximizing vitamin D production at higher latitudes and dark skin providing UV protection in equatorial zones. To identify the genes that give rise to the palette of human skin tones, Crawford et al. applied genome-wide analyses across diverse African populations (see the Perspective by Tang and Barsh). Genetic variants were identified with likely function in skin phenotypes. Comparison to model organisms verified a conserved function of MFSD12 in pigmentation. A global genetic panel was used to trace how alleles associated with skin color likely moved across the globe as humans migrated, both within and out of Africa. Science , this issue p.
