Sled dogs' Arctic work left marks in their bones

A study suggests that millennia of pulling sleds across the Arctic have physically shaped sled dogs. Researchers found modern sled dogs have leg bones about 6% shorter than those of wolves, spitzes and other dogs, a trait that lowers their center of gravity and suits the demanding work of crossing frozen terrain alongside humans.
Why now: The surprising finding that hard labour visibly changed dogs' skeletons is a striking piece of science news.
