Evidence uncovered in a field in Suffolk, England indicates that ancient humans intentionally harnessed fire more than 350,000 years earlier than previously believed. This has made it difficult to find evidence of early fires and determine when early humans made the leap from opportunistic to intentional flame wielders. This suggests that local early humans worked at a campfire or hearth on multiple occasions to manufacture their flint axes. Further evidence comes from the iron pyrite uncovered at the site. The team believes that the area’s hominins who understood pyrite’s utility sourced it elsewhere before bringing it to the Barnham site.
