When we hear about the "black death," a couple things come to mind: the death of tens of millions of people, and ... rats.
Our history teachers taught us that the epidemic from 1347-1353 was likely spread by rats carrying fleas infected with bacteria.
And due to this rats may have been getting a bad rap the last 650 years or so. But a new theory says that there is a different culprit behind spreading the disease.
Gerbils. Actually to be more specific, a species of squirrel-sized gerbil from Asia called the great gerbil.

Gerbils may have caused the Black Death epidemic

The Plague, also known as the Black Death, was a disease caused by Yersinia Pestis, an infection carried by fleas living as parasites on rats. The Plague hit London in late 1664, having ravaged Holland the previous year, and killed around 100,000 people in and around the city. The dead were collected at night and thrown into common burial graves. (Photo by Oxford Science Archive/Print Collector/Getty Images)
The study found the climate was warmer and wetter in Asia during outbreaks, which meant more plague among the great gerbil population there.
"Now, the team is planning to analyze the DNA of plague bacteria from ancient skeletons across Europe to see if their theory is correct. If it is, it could cast this fluffy little pet in a whole new light," the BBC anchor reported.
Or maybe not. It seems the rats still aren't gonna catch a break. Gizmodo broke the news to its viewers by saying the plague was spread by "cute gerbils" and not "dirty rats."
The study says rats were probably responsible for maintaining the plague on ships, which would have spread it to ports across Europe. We're thinking we're going to just get a pet cat or dog instead.
