Overview

• Genetic analysis shows the two mummies are two-month-old wolf cub sisters, not early domesticated dogs.
• DNA places the cubs within a now-extinct Pleistocene wolf population with no direct link to modern dogs.
• Stomach contents reveal a varied carnivorous diet that included woolly rhinoceros meat and a small bird species.
• Researchers infer that Pleistocene wolves may have been larger than modern wolves based on the size of their prey.
• The cubs likely died when their underground den collapsed, and there is no evidence they interacted directly with humans.
