People With This Neanderthal Hormone Receptor Have More Muscle Mass
Are you regular swole? Or neanderthal swole? The post People With This Neanderthal Hormone Receptor Have More Muscle Mass appeared first on Nautilus .
Neanderthals, despite being shorter and more stocky than modern humans, were found to be more muscular. A recent study published in Current Biology reveals that this increased muscle mass could be attributed to a slight alteration in the Neanderthal growth hormone receptor. When cultured muscle cells exhibited the Neanderthal receptor, they grew 40 percent larger than normal cells in response to human growth hormone.
Modern humans have inherited this variant from interbreeding with Neanderthals around 47,000 years ago, and it is present in roughly 24 percent of South Asians. The researchers discovered that modern humans with this receptor variant have slightly different jaw shapes, shorter tooth roots, and more muscle mass, although the effect is only around 9.5 ounces.
The study authors noted that the laboratory and population evidence strongly support the connection between the Neanderthal receptor and increased muscle mass in humans.
