A recent study published in Scientific Reports highlights that ancient hominins, living nearly 800,000 years ago, exhibited advanced tool-making skills by carefully selecting specific types of stones for different tools. The research focused on the Gesher Benot Ya’aqov (GBY) site in present-day Israel, where evidence of Acheulian hominins shows their ability to use controlled fire, process plants, and create sophisticated stone tools. The study found that basalt was a key material for making large cutting implements, and researchers traced its origins to local volcanic sources, revealing a deliberate selection process rather than random collection. By analyzing the chemical makeup of artifacts, the team identified unique geochemical signatures of basalt deposits, reconstructing an ancient landscape altered by tectonic activity. The consistent patterns of stone selection across various archaeological layers suggest a shared technological tradition that was likely passed down through generations, indicating that these early humans possessed a level of planning and resource management previously thought to be characteristic of later populations.
