A researcher who excavated 12 layers of soil deposits from the shore of an ancient lake near the river Jordan found evidence that fire had been used by humans in every layer. The soil layers were laid down by waters from the lake in between occupancies by the different societies of humans that inhabited the site 790,000 years ago. Nira Alperson-Afil from the Hebrew University of Jerusalem, Israel, concluded that humans would have had to have mastered the art of creating fire for it to have shown up in all 12 layers.
Previous research had shown that humans from this period could manipulate and use fire, but it was not clear whether they had the ability to create the fire themselves.
The researcher did not say if 790,000 years ago the users of fire had to obtain burning permits, get NEPA compliance, or write burn plans before they started their fires.
