An ancient bone fragment holds clues to how dogs got to the Americas, researchers report. The research reports that a bone fragment found in Southeast Alaska belongs to a dog that lived in the region about 10,150 years ago. Scientists say the remains a piece of a femur represent the oldest confirmed remains of a domestic dog in the Americas. DNA from the bone fragment holds clues about early canine history in this part of the world. Researchers analyzed the dog’s mitochondrial genome, and concluded that the animal belonged to a lineage of dogs whose evolutionary history diverged from that of Siberian dogs as early as 16,700 years ago. The timing of that split coincides with a period when humans may have been migrating into North America along a coastal route that included Southeast Alaska. ....

New World Dog Bone Fragment Dated to 10,200 Years Ago BUFFALO, NEW YORK According to a Science Magazine report, a 10,200-year-old fragment of dog bone has been identified among thousands of ancient bone pieces discovered in a cave on the west coast of Alaska in 1998. Charlotte Lindqvist of the University at Buffalo said DNA analysis has revealed that the dog was closely related to dogs domesticated in Siberia about 23,000 years ago, and was descended from a population that split from its Siberian ancestors about 16,700 years ago. “Understanding how the dogs moved also shows you how the humans moved,” explained team member Flavio Augusto da Silva Coelho. Previous studies of human DNA also suggest that modern Native American populations split from Siberian ancestors around the same time. Chemical analysis of the dog bone indicates that the creature ate a diet based on marine animals, likely scraps of fish, seal, and whale hunted by human companions traveling by b ....
