Ancient Bone Modifications Point to Ritualistic Human Remains

A study published in PLOS ONE reveals that bone remains found in the Cueva de los Mármoles cave in Spain were modified for ritual use rather than consumption. The research team analyzed over 400 remains and observed marks on the bones that were consistent with a cleaning process for instrumental use. Carbon-14 dating indicated three periods of funerary use in the cave, coinciding with the Neolithic and Bronze Age. The findings suggest that the bones were used as instruments in rituals, reflecting a cultural practice spanning a significant period of time.
