What happened
Dogs have long helped people travel across the Arctic, hauling supplies and equipment through snow where other domesticated animals struggled. A new study published October 14 in the journal iScience finds that sled dogs might have evolved shorter legs. The findings tie this trait to about 9,000 years of such work.
Why it matters
If the findings hold, the dogs' stubby legs would be a lasting result of millennia spent pulling people through the Arctic.
