Fire, scientists agree, helped give rise to a successful, thriving human population by providing heat for cooking and protection from the cold.
But they don’t agree【C1】______when humans began using fire. Some researchers argue that it【C2】______more than a million years ago when early humans【C3】______their way to Europe from Africa, and【C4】______say it happened much later. Now, a new study reveals that humans did not【C5】______fire until about 400 000 years ago.

They think there is no clear evidence of【C8】______fire use until about 400 000 years ago. In Africa,【C9】______there are several sites where there was evidence of fire, those may have been【C10】______fires that occurred in the African grassland.【C11】______, there are also sites older than 400 000 years in Europe that indicate the【C12】______of humans, with the oldest, in Spain, more than a million years old.
