Abstract

This article examines genomic findings in the DNA of the world's wild cats and says the information has clarified the cat family tree and uncovered remarkable migrations in their past. DNA evidence shows that all living cats trace back to a pantherlike predator that lived in Southeast Asia nearly 11 million years ago. The big roaring cats were the first to branch off and seven other lineages followed. As the sea levels rose and fell, the cats migrated and developed into new species.

Abstract

The world's domestic cats carry patterns of sequence variation in their genome that reflect a history of domestication and breed development. A genetic assessment of 979 domestic cats and their wild progenitors—Fells silvestris silvestris (European wildcat), F. s. lybica (Near Eastern wildcat), F. s. ornata (central Asian wildcat), F. s. cafra (southern African wildcat), and F. s. bieti (Chinese desert cat)—indicated that each wild group represents a distinctive subspecies of Fells silvestris. Further analysis revealed that cats were domesticated in the Near East, probably coincident with agricultural village development in the Fertile Crescent. Domestic cats derive from at least five founders from across this region, whose descendants were transported across the world by human assistance. [ABSTRACT FROM AUTHOR]
