Many Alaska cruise excursions include time with sled dogs, so this might be of interest.

 

A 35-person team, including a who’s who of ancient DNA experts, has now uncovered a vivid and genetically detailed picture of the oldest known case of selective breeding, the creation of Arctic sled dogs at least 9,500 years ago.

By that time, the researchers found, sled dogs already had mutations in genes involved in oxygen use and temperature sensitivity that set them apart from other dogs and wolves.
