The gist
Neanderthal gene variant linked to greater muscle mass in modern humans. The variant affects growth hormone receptors, possibly explaining some people's brawnier builds.
Background
Modern humans carry some Neanderthal DNA due to interbreeding about 47,000 years ago. A new study published in Current Biology identified a variant of the growth hormone receptor gene inherited from Neanderthals that may influence muscle development. Researchers analyzed data from over 1.1 million adults and found carriers were slightly taller and heavier on average.
How it unfolded
- Aug 5, 2026Study published in Current Biology identifying the Neanderthal growth hormone receptor variant.
- Aug 11, 2026Smithsonian Magazine and Live Science report on the study, highlighting the gene's effect on muscle mass.
- Aug 13, 2026Archaeology Magazine covers the finding, noting the gene is linked to greater muscle mass.
- Aug 15, 2026The Debrief reports on the study, emphasizing the convergence of lab experiments and population data.
Who’s saying what
- Expert
- Senior author Hugo Zeberg said, 'It is fascinating that one genetic change inherited from Neandertals can still have an effect on the human body today.'
- Expert
- Co-author Miriam Berreiter commented, 'As someone who does CrossFit, I was delighted to find Neandertal genetics and muscle mass coming together in the same study. But even a Neandertal growth hormone receptor is no substitute for training.'
Still unverified
The study's findings are based on statistical associations and lab experiments; the exact mechanism by which the gene variant affects muscle mass is not fully confirmed.
