Today's house cat (Felis catus) is a direct descendant of Felis silvestris lybica, otherwise known as the African wildcat. Still spread across Africa but also west and central Asia, the African wildcat is slightly larger than its tamed descendants, and the process of domestication likely began around 10,800 years ago in the Middle East/North Africa region. However, evidence suggests that a second cat species, the leopard cat (Prionailurus bengalensis), was separately domesticated in neolithic China around 5,000 years ago. (Today, the modern Bengal cat is a mix between this wildcat and Felis catus.) In both instances, cats were domesticated far later than dogs, which some estimates say occurred as far back as 32,100 years ago. This explains why house cats retain more genetic, behavioral, and even physical traits of their wild ancestors compared to most dog breeds. | |
