Recent study suggests that the entire population of the domestic dog (Canis lupus familiaris) today are descended from three females near China about 15,000 years ago. A burial site in Germany called Bonn-Oberkassel has joint human and dog interments dated to 14,000 years ago. The earliest domesticated dog found in China is at the early Neolithic (7000-5800 BC) Jiahu site in Henan Province. European Mesolithic sites like Skateholm (5250-3700 BC) in Sweden have dog burials, proving the value of the furry beasts. Danger Cave in Utah is the earliest in the Americas, at about 11,000 years ago.
