Archaeological evidence uncovered in a Spanish cave suggests cannibalism was practiced during the Neolithic period. Hundreds of fragmented human bones, dating back approximately 5700 years, show signs of being processed and consumed. Cut marks and evidence of marrow extraction indicate a systematic approach to cannibalism. This discovery adds to the growing body of evidence suggesting that cannibalism, while perhaps not widespread, was a more common practice in prehistoric societies than previously believed, possibly driven by survival needs or ritualistic practices.
