People know when fire?

The international team examined charcoal from a fireplace in the Pedra Furada archaeological site (in Serra da Capivara National Park, Brazil).

They use technology that is more advanced than the radiometric timing method and found the first humans to use fire to heat in rock caves at least 56,000 years ago. This result seems to be 40,000 years earlier than the unified conception of the time people set foot in America.

Pedra Furada area, which has many caves - a place of prehistoric people, contains many archaeological values ​​of human traces. Scientists still wonder if those fire stoves are human works or simply a natural remnant of nature. However, the new study shows that the fire stove was independently created from the stones found outside in the same geological layer, so it is possible to eliminate the possibility of stones heated by self fire Of course.
