Archaeologists Say Fire Caused Tuberculosis

Fire caused tuberculosis according to new archaeological theory.
Evolution is very powerful. A change in climate leads to the survival of those who suit the new climate more adequately. A series of ice ages meant hairy people with narrow nasal passages (to warm the damaging cold air on it way into the lungs) passed on their genes. People living in central Africa remained in a warm climate, so they did not have to adapt.

A new premise is that the adoption of fire by early humans caused the emergence of tuberculosis. Apparently, many people crouching around a fire set the ideal conditions for TB to take hold. Just a minute though. Didn't Africans also cook meat on fires and kept near to it for warmth on cold nights? They certainly did. No, this new theory does not hold up.

It is assumed that TB is mainly a thing of cold climates.  More correctly, molecular archaeological evidence shows that TB began in Africa. Just how scientists reached the conclusion that humans passed it on to animals is beyond me, though. This is pie in the sky stuff, mere speculation.

Man has been using fire for at least 200,000 years. This is obvious. Scientists say TB appeared anywhere from 70,000 to 6,000 years ago. Such debate about the correct time of its occurrence means a lot of work has to be done before TB can be linked to fire.

Link Between Diabetes and TB

There could be link to diet for tuberculosis. It seems people with diabetes are likely to also have tuberculosis in tropical Australia. Little is said about it, but tuberculosis is the leading cause of bacterial death in the world. It has also been known for some time about the predilection to have tuberculosis in people with diabetes.

It could be a "racial" trait. Australian Aboriginals and those of Torres Strait descent are high on the list. having diabetes makes sufferers susceptible to immune dysregulation with opens people to infection generally. It is only rational to screen those with diabetes for tuberculosis. This is not currently done.

It is not known if dysregulation is the cause of problem. Historical data is not much help because diabetes was not an identifiable disease while TB was, in past centuries. Research is being done to find find the reason for it. Reduce the prevalence of diabetes and cases of TB fall. It is as simple as that.
