Fire transformed daily life for early humans, providing warmth, cooked food, light after dark, and protection from predators. A new archaeological study suggests that Neanderthals were not merely maintaining natural fires but may have known how to start them on demand more than 400,000 years ago.
The research focuses on evidence from Barnham, an archaeological site in Suffolk, England. Scientists examined a patch of soil that had turned reddish, a color change typically caused by intense heat. Nearby, they found flint fragments cracked in patterns consistent with repeated exposure to fire. Flint was commonly used by early humans to make tools.
One of the most significant discoveries was the presence of iron pyrite, a mineral capable of producing sparks when struck against flint. Pyrite is rare in the Barnham area, leading researchers to believe it was carried to the site rather than found naturally. This suggests the material may have been deliberately transported as part of a fire-making kit.
The team also found signs that the same area was heated multiple times – a pattern difficult to explain through a single wildfire or lightning strike. To strengthen their case, researchers used advanced methods, including micromorphology, which studies ultrathin slices of soil under a microscope, and environmental magnetism, which detects heat-related changes in iron minerals within sediment.
Together, the findings point to controlled, repeated fire usage between 400,000 and 415,000 years ago. If confirmed, this would be among the earliest evidence that humans or human relatives could reliably make fire.
The implications are significant. Regular access to fire would have allowed Neanderthals to cook food, plan camps near water, stay warm, and gather safely after dark. Fire also supported later technologies, such as adhesives to attach stone tools to wooden handles. The study suggests Neanderthals were already capable of more than just surviving – they were organizing daily life around a tool they could control.
