Neanderthal DNA variant linked to increased muscle mass in humans
Research featured in 'Current Biology' indicates that a specific growth hormone receptor variant passed down from Neanderthals enhances cell sensitivity to growth hormones, resulting in a 40% increase in growth during lab experiments. Individuals possessing this Neanderthal gene variant typically have about 270 grams of additional muscle mass. This particular receptor is found in as many as 24% of individuals within certain South Asian communities.
