Recently, a thousand years ago mummy with the PCR system (Polymerase Chain Reaction) has been studied in Peru and fragments of DNA from the Mycobacterium tuberculosis bacteria have been found. Momia is a 40-45 year-old woman who, being Christopher Columbus 500 years before her arrival in America, has discovered that there was a tuberculosis bacterium.
Thanks to molecular biology, much progress has been made in paleontology. Until now, only hypotheses could be made, since the different microorganisms cause the same lesions.
