Consumption, phthisis, scrofula, Pott's disease and the White Plague are all terms refer to tuberculosis throughout history. It is generally accepted that the microorganism originated from genus Mycobacterium. In 2014, results of a new DNA study of a tuberculosis genome reconstructed from remains in southern Peru suggest that human tuberculosis is less than 6,000 years old. Researchers theorize that humans first acquired it in Africa about 5,000 years ago. It spread to other humans along trade routes. It also spread to domesticated animals in Africa, such as goats and cows. Seals and sea lions that bred on African beaches are believed to have acquired the disease and carried it across the Atlantic to South America. Hunters would have been the first humans to contract the disease there.
