Ancient Dog DNA Shows Human-Dog Bond
Чтение
Scientists found new proof that dogs are very old friends of humans. Dogs came from ancient wolves that learned to live with people.
Two studies used old dog genes to learn more about dog history. They found the oldest dog DNA from almost sixteen thousand years ago.
Dogs were already in Europe and Asia over fourteen thousand years ago. They lived with people who hunted and gathered food, moving often.
Dog genes in Europe did not change much when farmers arrived later. But dog genes in Asia show more changes from their owners' travels.
Early dogs likely looked like smaller versions of today's wolves. They might have helped hunt or played with children in ancient times.
