The Mummy's Tale
A woman's remains prove that tuberculosis existed in the New World before Columbus crossed the sea
By ANASTASIA TOUFEXIS
The ghosts of Columbus and his fellow European explores can breathe a bit easier. For a long time they _13_ accused of slaying New World natives not just with swords but also with germs. Supposedly, the sailors – and eventual settlers – brought with them the bugs for _14_ illnesses unknown in the Americas, including smallpox, measles, influenza, malaria and tuberculosis. Never having been exposed to these ailments, natives had _15_ immunity. Now, _16_, the European invaders have been exonerated as the carriers of at least one disease to the New World. Scientists said last week that they had found DNA from TB bacterium in the mummified remains of a woman who _17_ in the Americas 500 years before Columbus set sail from Spain.
Paleopathologists had suspected that TB existed in the New World before 1492. Ancient skeletons, for instance, _18_ bone lesions that resemble those caused by TB. But the DNA discovery, reported in the Proceedings of the National Academy of Sciences, is the first firm proof of TB's longevity in the Americas.
The big mystery: _19_ to the Americas? _20_ people migrating from Asia across the Bering Sea land bridge take the disease to the new land? Those travelers, thousands of years earlier than Columbus, may have carried the answer to _21_ graves. If so, scientists may one day unearth _22_.
