Onset of extensive human fire use 50,000 y ago | PNAS By integrating pyrogenic carbon records with archaeological data, we propose that intensified human global expansion, population growth, and rising demand for fire use during cold glacials resulted in a surge in fire use since approximately 50,000 y ago
Scientists discover evidence of extensive human fire use 50,000 years ago This study, published in the Proceedings of the National Academy of Sciences (PNAS), highlights the presence of charred plant remains — known as pyrogenic carbon — formed when vegetation burns but is not completely consumed by fire The research reveals a notable increase in fire activity across East Asia approximately 50,000 years ago
Onset of extensive human fire use 50,000 y ago - PubMed Here, we report a pyrogenic carbon record of East Asian fire history over the past 300,000 y from the East China Sea This record suggests a rapid increase in fire activity since approximately 50,000 y ago, indicating a decoupling from the monsoon climate, and this pattern is consistent with fire histories in Europe, Southeast Asia, and Papua
New study uncovers 50,000-year legacy of man-made fires Carried by river systems from East Asia over the past 300,000 years, these particles provide a continuous record of fire activity Carbon records from the site show fire activity spiked around 50,000 years ago, surprising researchers, including key authors Shoushu Jiang and Debo Zhao
An Ancient Warming Event May Have Lasted Longer Than We Thought Piedrahita et al now suggest that the warming event lasted almost 269,000 years Evidence of the PETM is indicated in the geological record by a substantial drop in stable carbon isotope ratios
