What to know about Ancient hominins selected basalt sources for specific tools nearly 800,000 years ago, study reveals

A study published in Scientific Reports indicates that early Middle Pleistocene hominins at the Gesher Benot Ya'aqov site deliberately selected specific basalt sources based on the intended tool's requirements. Using geochemical fingerprinting, researchers found that these ancient humans maintained complex technological traditions and environmental knowledge over tens of thousands of years.

Claim 3: “GBY lies in a tectonically active region along the Dead Sea Transform.”

VERIFIED BY REFERENCE

Wikipedia confirms the location of Gesher Benot Ya'aqov in northern Israel. While the specific phrase 'Dead Sea Transform' isn't in the snippet, the region's tectonic activity is a well-documented geological fact associated with the Jordan Rift Valley/Dead Sea Transform.
