Researchers in Israel used artificial intelligence to determine that ancient people living at the Evron Quarry site burned flint and animal bones.

Scientists think they could have come across the location of the world's oldest campfire - and it's over a million years old. Flint tools and animal bones had been excavated from a quarry in Israel, thought to have been inhabited by our ancient ancestors, Homo erectus. Researchers investigated the ability of these artefacts to absorb ultraviolet (UV) and infrared (IR) radiation – which is affected by burning. They compared the results to those from similar unburnt materials, and concluded that they had been heated to temperatures between 390 F (200 C) and 1100 F (600 C). The team from the Weizmann Institute of Science in Israel also analysed bits of tusk from of an elephant-like animal that had been found in the same sedimentary layer as the tools.
