Did early campfires trigger tuberculosis?

Fire brought warmth and comfort to early humans but may also have triggered the emergence of deadly tuberculosis, Australian researchers suggest.

Smoke-damaged lungs, as well as the closeness of humans around a campfire, could have created the ideal conditions for tuberculosis to mutate from a harmless soil bacterium into our number one bacterial killer, according to the researchers' data model.

The model, published today in the Proceedings of the National Academy of Sciences, showed controlled use of fire would have increased the likelihood of tuberculosis emerging by several orders of magnitude.
