New research from the American Museum of Natural History and the Smithsonian finds that most modern dogs have low wolf ancestry, influencing body size and personality.
The study analyzed over 2,700 genomes, showing that nearly two-thirds of breed dogs carry wolf genes from crossbreeding about 1,000 generations ago.
Village dogs, about half of the global population, consistently show wolf DNA, suggesting it aids survival in harsh environments.
