Ancient Cannibalism Evidence Discovered in Human Bones from Spanish Caves

The discovery of human remains in caves in northern Spain indicates that Neolithic people may have resorted to cannibalism after battles.

Francesc Marginedas from the Catalan Institute of Human Paleoecology and Social Evolution (IPHES) in Tarragona, along with his team, examined fragments from 650 human remains found in El Mirador cave on Mount Atapuerca. These remains date back approximately 5,700 years and belong to 11 individuals.

All examined bones displayed evidence that these individuals had been consumed by other humans. Some exhibited chop markings made by a stone tool, while others showed translucent portions with gently rounded edges. Some of the long bones were fractured open with stones to access the bone marrow, and smaller bones like metatarsals and ribs had clear human bite marks.

This research supports the notion that cannibalistic practices were more prevalent in human history than previously believed.

El Mirador marks at least the fifth significant site in Spain with notable evidence of cannibalism during the Neolithic era, a shift period from foraging to agriculture, according to Margida. “There’s a growing understanding that such behavior was more frequent than we anticipated.”

The motives behind these cannibalistic acts remain unclear. Some archaeological sites show skull cups indicating a ritualistic aspect to cannibalism, while others hint at survival strategies during dire circumstances.

However, Marsidas and his team propose that the findings at El Mirador suggest these acts were linked to warfare. There was a significant amount of animal remains, and no signs of nutritional stress among the humans involved, indicating this early agricultural community was not struggling with food scarcity. Their findings offer no indication of ritualistic behavior, as human bones were found alongside animal remains.

The ages of the individuals ranged from under seven to over fifty, implying that an entire family unit may have been lost to conflict. Radiocarbon dating indicated that all 11 individuals were killed and consumed within a few days.

This evidence reflects patterns of conflict and cannibalism, which have also been noted at two other Neolithic sites: the Von Bregore Caves in France and Helxheim in Germany. This period appears marked by instability and violence due to community clashes with neighboring groups and newcomers.

While Margida and his colleagues are uncertain about the reasons behind these cannibalistic practices, historical ethnographic studies suggest that such acts during warfare can serve as a method of “ultimate exclusion.” “We believe that one group attacking and consuming another serves as a humiliating statement,” states Merseydus.

“The thoroughness of the body’s treatment and consumption is remarkable.” Paul Pettitt from Durham University, UK, comments, “The aggressive nature shown in these artifacts, regardless of whether the consumed were relatives or adversaries, mirrors a dehumanization process during consumption.”

Sylvia Bello from the Museum of Natural History in London concurs that this evidence of death likely ties back to conflicts but remains skeptical about the notion of consumption as humiliation. She suggests that cannibalism may stem from aggression and animosity rather than ritualized farewell practices, implying a more complex interpretation. “It could carry ritual significance, even amid warfare,” she asserts.
