Six Neanderthals who lived in what is now France were eaten by their fellow Neanderthals some
100,000 years ago, according to fearful evidence of the cannibalistic ( 食人的 ) event discovered
by scientists in a cave in the 1990s. Now, researchers may have fi gured out why the Neanderthals,
including two children, became victims of cannibalism: Global warming.
Although previous studies have examined, 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 changes in local ecosystems as the planet warmed may have
wiped out the animal species that Neanderthals ate, forcing them to look elsewhere to fill their
stomachs.
The researchers examined a layer of sediment ( 沉积物 ) in a cave known as Baume Moula-
Guercy, in southeastern France. In that layer, charcoal ( 碳 ) and animal bones were so well-preserved
that scientists could reconstruct an environmental picture representing 120,000 to 130,000 years ago.
They discovered that the climate in the area was likely even warmer than it is today, and that the
change from a cold, dry climate to a warmer one happened quickly. “Maybe within a few generations,”
study co-author Emmanuel said. “As the animals that once populated the landscape disappeared, some
Neanderthals ate what they could fi nd—their neighbors.”
“Cannibalism is by no means unique to Neanderthals, and has been practiced by humans and
their relatives from the early Palaeolithic to the Bronze Age and beyond,” the study authors reported.
The behavior adopted by the starving Neanderthals in the Baume Moula-Guercy should therefore not
be viewed as “a mark of bestiality ( 兽性 ) or sub-humanity”, but as an emergency adaptation to a
period of severe environmental stress, according to the study. The fi ndings were published in the April
issue of the
