Innovation under pressure, not just in abundance, shaped early humans—useful context for a colleague following human origins.
Ancient bone crystals rewrite human innovation story Story flow and key facts
A new analysis of crystals inside a 146,000-year-old deer rib from the Lingjing site in Henan Province, China, has pushed back the site's age by 20,000 years, reshaping our understanding of early human innovation. Previously thought to date from a warm interglacial period, the site is now confirmed to belong to a harsh glacial era, when resources were scarce and survival was difficult. This shift overturns the long-standing theory that creativity and technological advancement only emerge during times of abundance and stability.
The stone tools found at Lingjing, particularly disc-shaped implements made using centripetal flaking, show a high level of planning and technical knowledge. These tools were not final products but were used to shape other tools, indicating a layered, forward-thinking approach to toolmaking. The cognitive complexity involved rivals that seen in Neanderthals and early Homo sapiens in Africa and Western Europe, challenging the outdated notion that East Asian hominins were technologically behind.
The humans responsible are believed to be Homo juluensis, a large-brained hominin with traits of both archaic East Asians and Neanderthals. Their ability to innovate under extreme environmental stress suggests that necessity, not surplus, may have been a key driver of early human creativity. This discovery adds to growing evidence that advanced cognition evolved independently or spread more widely than previously thought.
Facts
- Crystals inside a 146,000-year-old deer rib from Lingjing, China, were used to redate the site 20,000 years older than previously believed.
- The tools at Lingjing, made during a harsh glacial period, show advanced centripetal flaking technique requiring planning and precision.
- Lead researcher Yuchao Zhao notes the findings challenge the idea that innovation only occurs in times of abundance.
- Homo juluensis, a hominin with traits of archaic East Asians and Neanderthals, is believed to have made the tools.
- The discovery contradicts the long-held assumption that East Asian prehistoric cultures were technologically behind those in Africa and Europe.
