Healed Cut on 100,000‑Year‑Old Jaw Suggests Early Sharp‑Force Trauma

Microscopic and micro‑CT evidence points to a healed facial cut that could mark the oldest known stab‑type wound and raises questions about care and social behavior among early Homo sapiens.

Overview

  • Researchers report a cut mark on the lower left jaw of Qafzeh 25 that shows bone remodeling, meaning the individual survived for a significant time after the injury.
  • The lesion was identified using high‑resolution microscopy and micro‑CT scans that distinguish sharp‑force marks from other kinds of damage.
  • Authors say the cut is consistent with trauma from a sharp implement and, if that reading holds, would be the earliest documented sharp‑force injury in the archaeological record.
  • Qafzeh cave's long record of deliberate burials and its stone‑tool assemblage, which includes sharp points and scrapers, provide plausible tools and social context but do not prove the cause or intent of the wound.
  • The finding adds data to debates about early violence, medical care, and funerary practices because the healed wound implies survival and possible social support, yet the exact implement and circumstances remain unresolved.
