A highly effective protection against oxidative stress developed by present-day humans

Very few proteins in the body have a change that makes them unique compared to the corresponding proteins in Neanderthals and apes. Researchers at the Max Planck Institute for Evolutionary Anthropology in Germany and Karolinska Institute in Sweden have now studied one such protein, glutathione reductase, which protects against oxidative stress.
