ベルギーの Goyet 洞窟で発見された約4万1千年〜4万5千年前のネアンデルタール人骨集合体を再解析したところ、成人女性あるいは思春期女性および若年個体が、体系的かつ選択的に食人の対象になっていたことが明らかになった。骨には新鮮な骨折・打撃痕があり、付近で食用とされた動物骨に見られる加工痕と同様の痕跡が確認された。被処理個体は外部集団出身とされ、地元集団ではなく、捕らえられて持ち込まれた可能性が高い。これは宗教的儀礼ではなく、栄養目的または領域争いや集団間の対立を背景とする捕食的行為(外部グループを対象とした食人)と考えられている。研究はDNA・同位体・形態計測・年代測定を統合しており、ネアンデルタールの集団間競争や消滅過程に関する新たな視点を提供するものとなった。

Neandertal human remains from the Troisième caverne of Goyet (Belgium). Highly fragmented bones bear traces characteristic of fresh bone fracturing and percussion, demonstrating intentional treatment of the bodies. The individuals (GNx, for “Goyet Neandertal” x), numbering six at minimum, were identified by genetic analyses: XX indicates female gender, and XY male gender.© Royal Belgian Institute of Natural Sciences /Scientific Reports

Abstract

The Troisième caverne of Goyet has yielded the largest assemblage of Neandertal remains in Northern Europe with clear evidence of anthropogenic modifications. However, its skeletal fragmentation has long limited detailed morphological and behavioural study on the assemblage. In this study, we integrate palaeogenetic, isotopic, morphometric, and structural analyses of the long bones to assess the biological profiles of the Neandertals from Goyet and explore whether they present particularities that could shed light on the formation of this unique cannibalised assemblage. We identify a minimum of six individuals, including four adult or adolescent females. Compared to Homo sapiens and Neandertals—including regional specimens—the females from Goyet display short statures and reduced diaphyseal robusticity of their long bones. They lack skeletal markers associated with high mobility despite isotopic evidence for non-local origins. The overrepresentation of short, morphologically gracile, non-local females, alongside two immature individuals, suggests a strong selection bias in the individuals present at the site. Dated between 41,000 and 45,000 years ago, a period marked by Neandertal cultural diversity, biological decline and the arrival of Homo sapiens in Northern Europe, the cannibalised female and juvenile Neandertals from Goyet indicate exocannibalism, possibly linked to inter-group conflict, territoriality, and/or specific treatment of outsiders.
