Onset of extensive human fire use 50,000 y ago | PNAS Fire is a pivotal aspect of human involvement in the carbon cycle However, the precise timing of the large-scale human fire use remains uncertain Here, we report a pyrogenic carbon record of East
Ancient Humans Were Using Fire to Shape the Earth 50,000 Years Ago Reference: Shoushu Jiang et al, Onset of extensive human fire use 50,000 y ago, Proceedings of the National Academy of Sciences (2025) DOI: 10 1073 pnas 2500042122 Love this? Share it and help us spark curiosity about science!
Scientists discover evidence of extensive human fire use 50,000 years . . . 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
Scientists discover evidence of extensive human fire use 50,000 years . . . The widespread use of fire likely propelled cultural and technological advancements while significantly altering ecosystems and the carbon cycle, said Zhao Debo, the study's corresponding author The discovery suggests that human impact on climate and vegetation commenced far earlier than current climate models recognize
New study uncovers 50,000-year legacy of man-made fires The team analyzed pyrogenic carbon, fire-derived chemicals, found in sediment layers in the East China Sea Carried by river systems from East Asia over the past 300,000 years, these particles provide a continuous record of fire activity
Fire at 50,000 years ago - Society for Interdisciplinary Studies The idea is that use of fire escalated as temperatures plunged during the Late Glacial Maximum The study could be divided into two parts as the sediment core appears to be recording landscape fires rather than human hearths It does involve considerable detail on the pyrogenic carbon record and is worth reading for that
