Content overview: “Ancient sled dogs evolved stubby legs to haul loads across Arctic for 9,000 years, study f”. For thousands of years, sled dogs have been indispensable to Arctic peoples, pulling sleds laden with supplies across vast frozen expanses. A new study published on October 14 in the journal iScience reveals that these dogs may have evolved shorter legs to become more efficient at hauling heavy loads. The research highlights a key adaptation that allowed them to thrive in harsh northern environments where other domesticated animals could not.
By analyzing ancient dog remains, scientists found that sled dogs from the past 9,000 years had proportionally shorter limbs compared to other dogs, a trait that likely improved their pulling power and energy efficiency. This discovery underscores the deep co-evolutionary relationship between humans and dogs in the Arctic, where survival often depended on reliable transportation.
