Story summary

A study led by Patrick Eppenberger links red blood cell incompatibilities in hybrid Neanderthal-human mothers to extinction.
The PIEZO1 gene variant in Neanderthals could have caused miscarriages with modern humans.
This incompatibility could have diminished hybrid offspring's reproductive capacity over generations.
Experts including April Nowell and John Hawks say the PIEZO1 variant may have aided Neanderthals initially but hindered survival, and researchers call for further study of other genetic factors.
