    Interesting article

    Disease-riddled Europeans, carrying tuberculosis across the Atlantic, have long been blamed for wiping out huge populations of Native Americans.
    But new research has found that the deadly bugs which killed millions were probably spread by seals and sea lions, long before Christopher Columbus first arrived in the New World in 1492.
    A study which looked at tuberculosis strains in bones discovered in Peru found they were closely linked to those found in sea mammals.
    The research shows that tuberculosis is likely to have spread from humans in Africa to seals and sea lions, who then carried the disease to South America and transmitted it to Native populations long before Europeans landed on the continent.
    "What we found was really surprising. The ancient strains are distinct from any known human-adapted tuberculosis strain," said Anne Stone, Professor in Human Evolution at Arizona State University.

    "We found that the tuberculosis strains were most closely related to strains in seals and sea lions.
    "Our results show unequivocal evidence of human infection caused by sea lions and seals in pre-Columbian South America.
    “Within the past 2,500 years, the marine animals likely contracted the disease from an African host species and carried it across the ocean to coastal people in South America.”


    I think your title was somewhat in jest, but just for those who are not aware- TB was just one of many diseases from the Old World which infected the new world- smallpox, influenza, diptheria- all of which New World inhabitants had no resistance to- and died at rates upward of 90%.

    Much of what European explorers thought to be 'uninhabited' were areas where the population had been wiped out by disease.
