Mycobacterium Tuberculosis is responsible for nearly 1.5 million deaths annually. Infected individuals are asymptomatic for months, which is responsible for worldwide expansion of this pathogen. Researchers have identified that Pre-Columbian strains of tuberculosis was transferred to humans from seals. Sequencing data from a 12,000 year old skeleton provided insights into human migration in the South Americas. Sequencing is revealing the hidden mysteries of the origins of diseases and human migration.
