New research suggests DNA incompatibility between humans and Neanderthals may have hastened their demise.

A new genetic study offers fresh insight into why Neanderthals disappeared after interbreeding with early modern humans. Researchers found that DNA incompatibilities between the two species may have made hybrid offspring less fertile or healthy, weakening Neanderthal populations over time. The findings add a new twist to the long-debated question of why Neanderthals vanished about 40,000 years ago. Scientists say this subtle genetic divide could have tilted the evolutionary balance in favor of Homo sapiens.
