Ancient DNA reveals how wolves transformed into today's companion dogs

At Clemson University, genetic specialist Kelsey Witt Dillon is decoding DNA from ancient dog specimens to illuminate the process by which wolves became the first domesticated animals. Findings indicate that early canines served functional roles such as hunting assistants, herd protectors, and sled pullers, and that their movements mirrored human migrations and commercial exchanges. By charting these patterns, scientists can infer aspects of prehistoric human societies.

Dillon also highlights that contemporary dog breeds possess reduced genetic variation, a factor behind many health issues and costly veterinary care. Investigating the broader genetic pool of ancestral dogs may offer strategies to enhance the wellbeing of modern breeds. The research underscores the intertwined evolution of humans and their earliest animal companions.
