Tracking the Origin of the Cat

Cats probably started living close to humans when people evolved from nomadic herding to raising livestock and crops and started storing food, which attracted mice and other rodents. Cats found good hunting there, and humans surely appreciated the sly little predators' help protecting their stocks."There was a mutual benefit," Lyons said.

From there, domesticated cats started to radiate out to different parts of the world, often following humans on their migrations. Today cats can be divided genetically into four broad groups: those from Europe, the Mediterranean, East Africa and Asia.

But Lyons and her colleagues also made surprising discoveries about individual breeds.

The Japanese bobtail, for example, does not seem genetically similar to cats from Japan, indicating the breed may have originated elsewhere.

Despite its name, the Persian, the oldest recognized breed, looks as though it actually arose in Western Europe and not Persia, which today is Iran.

Scientists have begun to pull back the feline veil, using the latest molecular tools to get a peek at the origin of the cat.

In one of the most comprehensive explorations of cats' origins to date, Leslie Lyons from the University of California at Davis, and her colleagues spent about five years collecting feline DNA, poking behind the whiskers of more than 1,100 Persians, Siamese, street cats and household tabbies around the world to swab inside their mouths.

The first thing the group did was confirm a report published last June in the journal Science that the domestication of cats about 10,000 years ago appeared to have occurred in an area known as the Fertile Crescent, which stretches from Turkey to northern Africa and to modern-day Iraq and Iran.

"Our data support the Fertile Crescent, specifically Turkey, as one of the origin sites for cats," said Lyons
"Turkey was part of the Fertile Crescent and hence was one of the earliest areas for agricultural development."
