Six Neanderthals who lived in what is now France were eaten by their fellow Neanderthals some 100,000 years ago, according to gruesome evidence of the cannibalistic event discovered by scientists in a cave in the 1990s.

Now, researchers may have figured out why the Neanderthals, including two children, became victims of cannibalism: global warming.

While prior studies have interpreted Neanderthal remains to find proof of cannibalistic behavior, this is the first study to offer clues as to what may have led Neanderthals to become cannibals. Scientists found that rapid shifts in local ecosystems as the planet warmed may have extinguished the animal species that Neanderthals ate, forcing them to look elsewhere to fill their bellies.
