Watch Earth Investigated online: Episode 14 Who Killed The Aztecs?

The mighty Aztec civilisation of Mexico was nearly wiped out in the 1500’s when almost 8 out of every 10 people across Central Mexico died in a series of devastating epidemics. Most people believe that these were diseases previously unseen in the New World, brought across the Atlantic by Spanish Conquistadores. But new research, lead by epidemiologists Rodolfo Acuna Soto and John Marr, suggests an entirely different explanation for the epidemics and, if their theory is correct, the fate of the Aztecs could repeat itself in the 21st Century.
