A newly published study reveals that early humans in Kenya’s Turkana Basin were crafting stone tools as far back as 2.75 million years ago, challenging long-held assumptions about the origins of technology in human history.
The tools, uncovered at the Namorototukunan site, represent one of the oldest and longest-lasting examples of Oldowan technology ever found. They remained in use for nearly 300,000 years, despite dramatic shifts in climate and landscape.
Researchers say the steady continuation of this toolmaking practice suggests a deeply rooted tradition passed across generations, offering a rare look into how early humans used technology to adapt to changing conditions.
The findings appear in the journal Nature Communications. The research team included experts from institutions across the globe.
Ancient innovation withstands environmental shifts
Anthropologist David R. Braun of George Washington University, the study’s lead author, said the tools were not a temporary innovation but part of a long-term cultural pattern. He added that the consistency in design over hundreds of millennia indicates knowledge was likely shared and preserved within hominin communities.
Susana Carvalho, senior author and director of science at Gorongosa National Park in Mozambique, explained that the findings support the idea that tool use was a widespread adaptation strategy among early primates, not limited to a specific moment or group.
Using advanced methods including volcanic ash dating, sediment magnetism, chemical analysis, and fossilized plant remains, researchers reconstructed the ancient environment. They found that early toolmakers lived through repeated wildfires, prolonged droughts, and major ecological changes.
How stone tools helped shape human history
Geoscientist Dan V. Palcu Rolier, a corresponding author from Utrecht University and the University of São Paulo, described the site as a rare glimpse into a world shaped by shifting rivers, drying climates, and fire-driven grasslands.
He emphasized that the tools remained largely unchanged throughout these conditions, highlighting early humans’ reliance on technology to face environmental instability.
Niguss Baraki of George Washington University said the sharpness and precision of the tools show that hominins were already skilled at making them by 2.75 million years ago, suggesting the origins of this technology may extend even further back.
Frances Forrest of Fairfield University noted that cutmarks on animal bones link these tools to meat consumption, indicating a broader diet that supported survival in harsh conditions.
Rahab N. Kinyanjui, of the National Museums of Kenya and the Max Planck Institute, pointed out that even as the landscape shifted from wetlands to semideserts, the core techniques of toolmaking endured. She said that kind of stability under pressure defines resilience.
