Ancient Neanderthals' Ingenious Stone Tool Adhesives Uncovered

A new study published in Science Advances reveals evidence of Neanderthals creating stone tools held together by a multi-component adhesive, showcasing a higher level of cognition and cultural development than previously thought. The tools, dating from 120,000 to 40,000 years ago, were found at an archaeological site in France and were wrapped and untouched since the 1960s. Traces of a mixture of ochre and bitumen were found on the tools, with tensile tests showing that this combination formed a malleable mass suitable for a handle. Microscopic wear analysis confirmed the use of adhesives in this way, shedding light on Neanderthals' technical abilities.
