 The text discusses the discovery of tuberculosis (TB) in ancient human remains, specifically in mummies from Hungary and Peru. Researchers found evidence of TB infection in these individuals, dating back to around 1000 BCE. The study suggests that TB may have originated from Africa and spread globally through human migration. The researchers analyzed DNA samples from the mummies and compared them with modern-day TB strains, finding similarities between the two. This discovery sheds light on the history of TB and its global spread.
