Neanderthal growth gene turns modern humans into muscle heads
People with DNA variant from our evolutionary cousins tend to have more lean muscle mass
Neanderthal DNA contributes to modern humans' muscular advantage. Approximately 1-2% of the global population possesses this genetic heritage. Researchers discovered a specific genetic variant in Neanderthals' growth hormone receptor that enhances cell growth. Laboratory tests showed cells with the Neanderthal receptor grew more efficiently than those with the modern human version.
Consequently, individuals carrying this receptor variant exhibit increased muscle mass - about 271 grams more, particularly prevalent in South and East Asian populations.
