Apparently….dogs here in North America have been around for almost 10 millenniums! Researchers have reportedly come across a bone fragment from what they believe to be the earliest confirmed domesticated dog in both North AND South America.
Samuel Belknap III, a University of Maine graduate student, found a bone fragment while analyzing a dried-out sample of human waste that was dug-up in southwest Texas back in the 1970’s. A carbon-dating test revealed that the bone was over 9,000 years old, and a DNA analysis also confirmed that the fragment came from a dog, not a wolf, coyote or fox.
And the fact that the bone fragment was discovered in a pile of old human feces means that dogs were used as a source of food thousands of years ago.

Because it was found deep inside a pile of human excrement and was the characteristic orange-brown color that bone turns when it has passed through the digestive tract, the fragment provides the earliest direct evidence that dogs — besides being used for company, security and hunting — were eaten by humans and may even have been bred as a food source, he said.
Belknap wasn’t researching dogs when he found the bone. Rather, he was looking into the diet and nutrition of the people who lived in the Lower Pecos region of Texas between 1,000 and 10,000 years ago. “It just so happens this person who lived 9,400 years ago was eating dog,” Belknap said.
Dogs have played an important role in human culture for thousands of years. There are archaeological records of dogs going back 31,000 years from a site in Belgium, 26,000 years in the Czech Republic and 15,000 years in Siberia, said Robert Wayne, a professor of evolutionary biology at UCLA and a dog evolution expert. But canine records in the New World aren’t as detailed or go back nearly as far.
For his research, Belknap — who does not own a dog himself — had fecal samples shipped to him that had been unearthed in 1974 and 1975 from an archaeological site known as Hinds Cave and kept in storage at Texas A&M University. The fragment is about six-tenths of an inch long and three- to four-tenths of an inch wide, or about the size of a fingernail on a person’s pinkie.
He and a fellow student identified the bone as a fragment from where the skull connects with the spine. He said it came from a dog that probably resembled the small, short-nosed, short-haired mutts that were common among the Indians of the Great Plains. Judging by the size of the bone, Belknap figures the dog weighed about 25 to 30 pounds. He also found what he thinks was a bone from a dog foot, but the fragment was too small to be analyzed. Other archaeological digs have put dogs in the U.S. dating back 8,000 years or more, but this is the first time it has been scientifically proved that dogs were here that far back, he said.
Darcy Morey, a faculty member at Radford University who has studied dog evolution for decades, said a study from the 1980s dated a dog found at Danger Cave, Utah, at between 9,000 and 10,000 years old. Those dates were based not on carbon-dating or DNA tests, but on an analysis of the surrounding rock layers. “So 9,400 years old may be the oldest, but maybe not,” Morey said in an e-mail. Morey, whose 2010 book, “Dogs: Domestication and the Development of a Social Bond,” traces the evolution of dogs, said he is skeptical about DNA testing on a single bone fragment because dogs and wolves are so similar genetically.
Belknap said there may well be older dogs in North America, but this is the oldest directly dated one he is aware of. For many years, researchers thought that dog bones from an archaeological site in Idaho were 11,000 years old, but additional testing put their age at between 1,000 and 3,000 years old, he said. “If there’s one thing our discovery is showing it’s that we can utilize these techniques and learn a lot more about dogs in the New World if we apply these tests to all these early samples,” he said.
The earliest dogs in North America are believed to have come with the early settlers across the Bering land bridge from Asia to the Americas 10,000 years ago or earlier, said Wayne, who has not seen Belknap’s research. It doesn’t surprise Belknap that dogs were a source of food for humans. A lot of people in Central America regularly ate dogs, he said. Across the Great Plains, some Indian tribes ate dogs when food was scarce or for celebrations, he said. “It was definitely an accepted practice among many populations,” he said.
We guess you really can’t teach an old dog new tricks, because dogs are old as hell!!!
