Ancient site reveals signs of mass cannibalism

The authors say their findings provide rare evidence of cannibalism in Europe's early Neolithic period.

Up to 500 human remains unearthed near the village of Herxheim may have been cannibalised.

The "intentionally mutilated" remains included children and even unborn babies, the researchers say.

The German site was first excavated in 1996 and then explored again between 2005 and 2008.

Team leader Bruno Boulestin, from the University of Bordeaux in France, told BBC News that he and his colleagues had found evidence the human bones were deliberately cut and broken - an indication of cannibalism.
