Researchers recently analyzed DNA changes in Ancient Europe. From this analysis, they created the hypothesis that the shift to agriculture is responsible for lighter skin pigmentation. The researchers supported this hypothesis by stating that the change in diet led to a decreased vitamin D intake.
This hypothesis on the evolution of skin pigmentation, although still centered around the idea of low vitamin D intake, slightly differs from the predominating theory. Scientists have believed lighter skin pigmentation developed to capture more vitamin D from less sun exposure when humans moved away from places near the equator. We have covered this theory many times before; click here to read our blog on the theory.
A recent article by The New York Times covered the exciting new research on DNA changes in Ancient Europe. Take a look.
