A gene variant inherited from Neanderthals may contribute to increased muscle mass in some people today, according to a report from The National Tribune. The outlet published the findings on Wednesday, August 5, 2026, citing research on the Neanderthal growth hormone receptor.
The National Tribune reports that the specific variant of the growth hormone receptor, which originated in Neanderthals, is still present in modern human populations. This genetic inheritance appears to influence muscle development, potentially offering a biological advantage in terms of physical strength or size.
The report, also covered by Mirage News under the headline "Neanderthal Gene Boosts Modern Human Muscle Mass," points to a direct link between the ancient gene and a measurable trait in contemporary humans. The research highlights how interbreeding between early modern humans and Neanderthals left a lasting genetic legacy that continues to affect physical characteristics.
This is not the first time Neanderthal DNA has been tied to traits in modern humans, but the specific focus on the growth hormone receptor provides a clearer mechanism for how the gene operates. The finding suggests that the receptor's function, inherited from Neanderthals, may alter how the body responds to growth signals, leading to increased muscle mass.
The National Tribune's report does not specify the exact size of the effect or the populations studied, but the implication is that the variant is widespread enough to be observed in people today. The research adds to a growing body of evidence that ancient hominid DNA has shaped human biology in subtle but significant ways.
What to watch next: Further studies may clarify how common this Neanderthal variant is across global populations and whether it influences muscle-related health conditions.
