Lethal wounds identified on a human skull in the Sima de los Huesos, Spain, may indicate one of the first cases of murder in human history, some 430,000 years ago, according to a study published May 27 2015 in the open-access journal PLOS ONE by Nohemi Sala from Centro Mixto UCM-ISCIII de Evolución y Comportamiento Humanos, Spain, and colleagues.

The archeological site, Sima de los Huesos in northern Spain, is located deep within an underground cave system and contains the skeletal remains of at least 28 individuals that date to around 430,000 years ago, during the Middle Pleistocene. The only access to the site is through a 13-meter deep vertical shaft, and how the human bodies arrived there remains a mystery.

A nearly complete skull, Cranium 17 from the Sima de los Huesos, is comprised of 52 cranial fragments recovered during excavations at the site over the last 20 years. This skull shows two penetrating lesions on the frontal bone, above the left eye. Relying on modern forensic techniques, such as contour and trajectory analysis of the traumas, the authors of the study showed that both fractures were likely produced by two separate impacts by the same object, with slightly different trajectories around the time of the individual's death. According to the authors, the injuries are unlikely to be the result of an accidental fall down the vertical shaft. Rather, the type of fracture, their location, and that they appear to have been produced by two blows with the same object lead the authors to interpret them as the result of an act of lethal interpersonal aggression—or what may constitute the earliest case of murder in .

Furthermore, if this individual was already dead, the authors found that they were likely carried to the top of the vertical shaft by other humans. The authors suggest that humans were likely responsible for the accumulation of bodies in the Sima de los Huesos, which supports the idea that this site represents early evidence of funerary behavior.
