780,000-Year-Old Basalt Tools Show Hominins Planned Stone Use at Gesher Benot Ya’aqov

Summary
Geochemical analysis of 780,000-year-old basalt tools at Gesher Benot Ya’aqov found hominins matched stone types to specific tasks rather than using whatever rock was nearest.
Basalt’s strength and weight made it useful for heavy cutting, and researchers linked large basalt cores to nearby sources while some cleavers appear to have come from still-unidentified basalt flows.
Those repeated material choices suggest toolmakers understood how different rocks fractured, planned ahead for desired shapes, and navigated the local landscape for suitable raw material.
The pattern also points to social learning in the Acheulian site, where repeated visits left tools, food-processing traces and evidence of fire use, implying knowledge passed across generations.
The findings add to evidence that early hominin technology long predated modern humans and already involved environmental awareness, experience-based skill and organized behavior.
