Artist’s impression of sparks from flint and pyrite

Round 400,000 years in the past, a band of Neanderthals, or their ancestors, in Britain struck flint with pyrite and constructed a hearth repeatedly in the identical spot. Archaeologists finding out the location assume it’s the earliest proof of people beginning fires ever discovered.
Early people might have been opportunistically utilizing hearth for round 1.5 million years. However it’s doubtless that these hominins merely made use of fireplace that had been ignited in different methods, corresponding to by lightning strikes.
Proof of extra in depth use of fireplace elevated in Europe from round 400,000 years in the past. Nonetheless, till now, we had solely direct proof that people may management ignition from round 50,000 years in the past.
Nick Ashton on the British Museum in London says there are three essential items of proof from the location his group has studied at Barnham quarry in Suffolk: pyrite, heated sediment and heat-shattered handaxes.
Pyrite is an especially necessary mineral within the historical past of people and hearth, as it may be struck towards flint to make sparks, which, in flip, can ignite kindling corresponding to dry grass to make a hearth. Nonetheless, pyrite doesn’t happen naturally close to the quarry web site, so it will need to have been introduced there by early people. “Pyrite is actually the clincher,” says Ashton.
However the reddish layer of sediment left by the hearth is sort of as necessary, he says. Burning alters the iron minerals within the sediment and might due to this fact change their magnetism. Laboratory experiments confirmed that the reddish clay sediment might have skilled hearth a dozen occasions – doable proof that people returned to the identical spot and lit fires repeatedly.
Heating flint could make it simpler to form into sharp instruments, however overheating could cause the flint to shatter – as is the case with the handaxes discovered at Barnham. Assessments confirmed they’d reached temperatures of over 700°C, so Ashton suspects they have been heated by chance.

Ashton says there may be rising proof that people from half one million years in the past have been proficient throughout a variety of cultural and technological expertise, together with fire-making.
“Early Neanderthals, and little question different up to date human species, have been much more succesful than we’ve usually given them credit score [for],” says Ashton. “Making hearth shouldn’t be simple and requires data concerning the sources of pyrite, its properties when struck towards flint and the fitting tinder to make use of to rework sparks into flames.”
John Gowlett on the College of Liverpool within the UK says, based mostly on the brand new discoveries, it’s “very credible” that individuals 400,000 years in the past have been routinely utilizing hearth and even making it.
“Early people have been actually conscious of fireplace, however discovering burnt issues along with instruments doesn’t routinely present human hearth management,” he says. “If in case you have repeated human occupations in a spot, and repeated proof of fireplace, that’s good proof for human management – as a result of pure fires don’t return usually.”
