Researchers have discovered the earliest known instance of human-created fire, which took place in the east of England 400,000 years ago.
The site, a former clay pit near the village of Barnham, contains a hearth made by Neanderthals about 415,000 years ago.
They discovered a baked earth that formed a hearth, heat-shattered flint axes and two fragments of pyrite - a type of stone used to create sparks for lighting tinder.
Until now, the earliest known evidence of humans making fire dated to around 50,000 years ago at a site in northern France, also linked to Neanderthals.
