A study published on July 7, 2026, reveals that a jaw wound found on a Homo sapiens specimen from Qafzeh Cave in Israel suggests possible interpersonal violence occurred around 90,000 years ago. The research, led by the Centro Nacional de Investigación sobre la Evolución Humana (CENIEH) in collaboration with Tel Aviv University, provides significant insights into early human behavior.
Details of the Fossil Analysis
The research team analyzed the Qafzeh 25 fossil, dated between 92,000 and 145,000 years ago. Through a combination of macroscopic and microscopic analyses, including high-resolution micro-computed tomography (microCT), they identified a linear lesion on the mandible and a lower premolar. This injury's morphology is consistent with sharp-force trauma, likely inflicted by a sharp object.
Signs of bone remodeling indicate that the individual survived for some time after the injury. While the exact cause remains uncertain, researchers propose that the injury was likely a result of interpersonal violence rather than an accident.
Insights into Early Human Health
The study identified additional dental conditions previously undocumented in early humans. Among these findings were:
- A hidden caries in a lower premolar detected using microCT.
- Enamel defects that provide insights into the individual's oral health.
These discoveries enhance our understanding of the biology and living conditions of early Homo sapiens populations outside of Africa.
Funerary Practices and Taphonomic Reassessment
The research also included a thorough taphonomic reassessment of the skeleton, allowing scientists to reconstruct the post-mortem processes affecting the remains. The results indicate that damage from carnivores or prolonged exposure was not present, suggesting the skeleton underwent deliberate burial.
This finding underscores the significance of Qafzeh Cave as a crucial archaeological site for examining early funerary practices. The evidence of a healed traumatic injury, dental pathologies, and deliberate burial creates a comprehensive picture of the lives and deaths of human populations in the Levant more than 90,000 years ago.
“These findings provide new evidence in the ongoing debate about the origins of complex behaviors such as interpersonal violence, the care of injured or ill individuals, and funerary practices,” says Ana Pantoja Pérez, first author of the study.
