Native American dogs were all but wiped out by settlers from Europe, study says


Ancient dogs arrived in the Americas alongside humans more than 10,000 years and — like those humans — were commonly exterminated by more newly arriving colonists from Europe, a new study suggests.

“European colonists viewed native dogs as kind of pests, and they freely killed them,” said Angela Perri, a research fellow at Durham University in England.

Colonists who killed entire villages of people would also kill their dogs. And when some early Spanish explorers would find themselves without enough food, they’d turn to native American dogs, she added.

In the study, researchers looked at genes from more than 71 archaeological dog remains in North America and Siberia and compared them with modern dog genes.

Perri, the study’s lead author, said it dispels the theory that dogs in the Americas evolved from wolves. The study was published July 5 in the journal Science.

The findings “put a nail in the coffin really for [that] idea,” she told Live Science. In the new data, “we just had absolutely no evidence of that.”

Instead, after analyzing samples from dog remains going back thousands of years from North America and Siberia, they suspect the first dogs came to the Americas more than 10,000 years ago, across the Bering land bridge that connected North America and Asia. The dogs dispersed across the Americas, where they lived for 9,000 years, isolated from the world.

Those were all but wiped out by early American settlers, and most American breeds today more likely trace their roots back to dogs brought to the country subsequently. Those include arctic dogs brought by the Thule people about 1,000 years ago, dogs brought by Europeans starting in the 15th century, and Siberian huskies brought to the American Arctic during the Alaskan gold rush.

By far, the introduction of European settlers and European dogs had the biggest impact on thinning out the ranks of native dogs, the study said.

“We suspect that a lot of the reasons [ancient] dogs were wiped out were similar reasons that Native American populations were destroyed,” Perri said. Europeans could have brought over diseases such as rabies and canine distemper that were probably not present in the Americas before.

Because settlers saw native American dogs as pests, they probably took steps to not let them breed with prized European dogs.

Indeed, out of 5,000 samples of modern dog genes, only five had genes that belonged to ancient dogs, and in those five, the ancient genes made up less than 2 percent of their genomes, Perri said.

The oldest known ancient American dog was found in Koster, Illinois, and lived around 9,900 years ago.

Does doggy bling date to prehistoric times?

A new study suggests the earliest domestic dogs weren’t just kept for hunting and protection, but for loving — a premise supported by evidence that some prehistoric pet owners actually outfitted their dogs in bling, if not before death, at least after it.

An analysis of ancient dog burials, published in PLoS ONE, found that deceased dogs were often laid to rest not just with respect, but with toys and ornaments, Jennifer Viegas reports on Discovery.com.

The findings show that, at least as recently as 10,000 years ago, dogs were valued for more than their ability to stand sentry and track game.

The researchers also say the earliest dog lovers were fish-eaters, and held spiritual beliefs. Subsisting on diets rich in seafood, they apparently didn’t rely on dogs to help them find dinner, or as dinner.

“Dog burials appear to be more common in areas where diets were rich in aquatic foods because these same areas also appear to have had the densest human populations and the most cemeteries,” Robert Losey, lead author of the study told Discovery News.

“If the practice of burying dogs was solely related to their importance in procuring terrestrial game, we would expect to see them in the Early Holocene (around 9,000 years ago), when human subsistence practices were focused on these animals,” Losey, a University of Alberta anthropologist, added. “Further, we would expect to see them in later periods in areas where fish were never really major components of the diet and deer were the primary focus, but they are rare or absent in these regions.”

For the study, Losey’s team researched dog burials worldwide, but focused particularly on ones located in Eastern Siberia. The earliest known domesticated dog was found there, dating to 33,000 years ago. Dog burials in the region are more recent, going back about 10,000 years.

They found that dogs were sometimes buried with meaningful items, sometimes even their human, showing that man’s bond with dog — while it may be ever-strengthening — goes way, way back.

According to the Discovery report:

“…One dog, for example, was laid to rest “much like it is sleeping.” A man was buried with two dogs, one carefully placed to the left of his body, and the other to the right. A dog was buried with a round pebble, possibly a toy or meaningful symbol, placed in its mouth. Still other dogs were buried with ornaments and implements, such as spoons and stone knives.

“One of the most interesting burials contains a dog wearing a necklace made out of four red deer tooth pendants. Such necklaces appear to have been a fashion and/or symbolic trend at the time, since people wore them too.”

The researchers found that most of the dog burials in the area occurred during the Early Neolithic era, about 8,000 years ago.

Siberian “dog-girl” likely to go back home

Here’s a report from Russia Today on Natasha Mikhailova – the five-year-old Siberian girl who walks on all fours, and barks, meows and eats like the dogs and cats she was raised among.

Natasha, who is only the size of a two-year-old, was removed from the unheated three-room flat she lived in with her dad and grandparents after neighbors complained to authorities.

The girl’s mother, according to the report, says she was taken away by her husband two years ago and that she hadn’t seen her since.

The father was fined for neglect, according to the report, and the girl is expected to be sent back home.
