Long before the first campfire was lit, early humans may have started as fire foragers, observing naturally occurring blazes and harnessing them for their own needs.
The ability to use fire forever changed the fate of the human race: For starters, it allowed our ancestors to cook foods, which made us much more efficient eaters. Instead of gnawing on nuts and berries all day, we could now cook animal meat, which packs much more of a caloric punch.
, he contends that the discovery of fire was a long process. “Early hominins would undoubtedly have been aware of fires, as are savanna chimpanzees in the present,” he writes. “Rather than as an event, the discovery of fire use may be seen as a set of processes happening over the long term.” Additionally, early humans may have used in-ground tree root systems — which stay warm for days after a bush fire — as a sort of natural oven. Admittedly, scientists don’t know exactly when this would have happened, as the phenomenon is hard to track with archeological evidence.The evidence for humans making fires themselves suggests it first started around, with some researchers speculating it began as early as 1.5 million years ago.
Modern humans, says Gowlett, largely can’t live without cooked foods for any length of time; that’s likely an adaptation that only came after we learned to cook effectively with fire.Humans and Neanderthals Used Fire Together
