When Did the First People Come to America? Just Ask Fido

Testing an ancient bear bone brought two discoveries: It was actually from a dog, and people came to North America much earlier than we thought.

When we think we know all we need to know about the first people in America, along comes man’s best friend to teach us yet another lesson in history, loyalty, and, surprisingly, immigration. For generations, scientists and researchers believed the earliest humans in Americas came about 12,000 years ago. They traveled from Siberia across the now-submerged land under the Bering Sea and into North America.

Today, researchers embrace the idea that humans traveled from Siberia through the Alaskan archipelago 16,000 years ago and traveled down the Pacific coast, avoiding massive glaciers migrating down the shorelines.

And all that changed just recently when specimen PP-00128 of the University of Alaska Museum, thought to belong to an extremely old bear, was genetically tested.  What scientists found instead was a miniscule femur fragment from one of the first dogs in America. The tiny bone fragment, the size of a fingernail, supports a significant timeline change of people migrating south from Siberia.

The entire collection dates back to 1998. This bone was found when scientists were excavating a tunnel-like cave on the southeastern coast of Alaska, hoping to discover ancient bears’ remains. Archaeologists also discovered the remains of fish, birds, mammals, and humans.

And scientists agree: “This is a fantastic study,” says archaeologist Loren Davis of Oregon State University, Corvallis, who was not involved in the research. Davis continued, “If the coastal migration theory is correct, we should expect to see exactly the kind of evidence reported in this study.”

But migration isn’t the only reason this find is important. It goes a long way in explaining the human/companion animal bond.

Man’s Best Bud

This femur bone is about 10,200 years old, making its owner the oldest dog known in the Americas, But the pup’s DNA tells an even more remarkable tale.

Researchers have narrowed the domesticating of dogs to Siberia 23,000 years ago. The bone fragment found indicates the dog was a descendent of the earliest known dogs in Siberia. The research team now estimates the two populations (Siberian/Alaskan) split 16,700 years ago based on genetic differences.

Chemical isotopes revealed that this dog ate marine animals, but most dogs aren’t skilled at fishing for supper, and that tells us their human companions fed them fish, seal, and whale scraps that they had successfully hunted. Is it any wonder those puppy dog eyes are so skilled at asking for human food? After 16,000 years of practice asking for food, they have perfected quite a dependent and doleful expression that gets excellent results today.

We aren’t privy to daily life of this Alaskan dog, but researchers have made some reasonable inferences, and experts can get close to a solid guess. Robert Losey is an archaeologist who focuses his studies on the human/animal relationship at the University of Alberta. He posits the dog would have weighed 50-60 pounds and said, “I would expect the dog to have been behaviorally similar to our own dogs, to be well adapted to cold environments, and probably also a participant in hunting, carrying loads, and pulling loads on sleds.”

Good Dog!
