What's happened
Recent excavations in China reveal early humans used advanced stone and composite tools 160,000 years ago, challenging previous beliefs about technological development in East Asia. Findings include the earliest evidence of composite tools and diverse species, indicating behavioral complexity and adaptability among ancient hominins.
What's behind the headline?
The new findings at Xigou significantly alter the narrative of human technological evolution in East Asia. The discovery of hafted, composite tools demonstrates that early Chinese hominins possessed planning skills and craftsmanship previously thought absent in the region. This suggests that behavioral flexibility and ingenuity were more widespread among ancient populations than previously believed.
Furthermore, the diversity of species, including large-brained hominins, indicates a complex ecosystem of human ancestors in China, comparable to those in Africa and Europe. The presence of sophisticated tool-making methods, such as prepared-core techniques and retouched tools, points to an advanced cognitive capacity that helped these populations adapt to fluctuating environments over 90,000 years.
These insights challenge the long-held view that East Asian early humans were technologically conservative. Instead, they reveal a dynamic and inventive human past, with implications for understanding the broader narrative of human evolution. The findings forecast a need to reassess the timeline and geographic spread of technological innovation, emphasizing that behavioral complexity emerged earlier and more broadly than previously thought.
What the papers say
The Independent reports that excavations at Xigou reveal advanced stone tools, including the earliest composite tools in East Asia, indicating high behavioral flexibility among hominins. The New York Times highlights discoveries of ancient wooden tools and a 500,000-year-old elephant bone hammer in Europe, suggesting early technological skills across regions. While The Independent emphasizes the significance of composite tools, the NYT underscores the broader context of early tool use, including organic materials. Both sources demonstrate that early humans possessed complex technical abilities, but the Chinese findings push the timeline of innovation further back, challenging the notion that East Asian populations lagged behind their counterparts in Africa and Europe.
How we got here
Previous understanding suggested East Asian early humans relied on simple stone tools, lagging behind Africa and Europe in technological progress. Recent discoveries at sites like Xigou, Xujiayao, and Lingjing show a richer technological landscape, with evidence of composite tools and diverse species, indicating a more complex evolution of human behavior in the region.
