Max Planck researchers discover the oldest ever images of dogs on leashes

While conducting research in the Saudi Arabian desert, scientists from the Max Planck Institute for the Science of Human History and the Max Planck Institute for Evolutionary Anthropology uncovered significant evidence of early human settlement in the region. Over 1,400 images carved in the rock show people hunting with dogs. The researchers believe they are at least 8,000 to 9,000 years old.
