The Plague
Interesting theory. Scientists now believe that the plague to hit Europe in the Middle Ages was more spread due to gerbils than due to rats moving from trade routes to on ships.
"What we are suggesting is that it was gerbils in Central Asia and the bacterium in gerbils that eventually came to Europe," Stenseth says. The scientists used climate records to check their theory, and they found a tentative link. When the climate in Asia was good, gerbils are thought to have thrived; but when it went bad, the population crashed. And about 15 years after each boom and bust, a plague outbreak erupted in Europe. The theory is that fleas carrying plague jumped from dead gerbils to pack animals and human traders, who then brought it to European cities. The research team's results appear in the current issue of the Proceedings of the National Academy of Sciences.
