⟩ Did Neanderthals use fire? Some estimates have Neanderthals living in Asia 200,000 years ago. Has this been verified or debunked?
Yes, of course they used fire. They used it for heat and for cooking. They were the original Bar-B-Q experts. In addition, since they evolved, they used fire. Even Homo erectus used fire.
As for living in Asia, they did not go to Far East but they were in Europe until about 40 thousand years ago. They exited from Africa some 600 thousand years ago and they have been found as Far East in Asia as the Ural Mountains and into the mountains of India. The last ones may have died out some 75 thousand years ago.
