A recent study sheds light on the early relationship between humans and dogs in the Americas, suggesting that this bond began around 12,000 years ago. The research, led by François Lanoë from the University of Arizona, was published in Science Advances and is based on archaeological findings in Alaska.

The study indicates that humans and the ancestors of modern dogs formed close relationships earlier than previously thought. "We now have evidence that canids and people had close relationships earlier than we knew they did in the Americas," said Lanoë. This discovery contributes to understanding whether early Americans arrived with dogs.

In 2018, researchers discovered a canine tibia at Swan Point, an archaeological site near Fairbanks, Alaska. Radiocarbon dating placed the bone at about 12,000 years old. Another find in June 2023 involved an 8,100-year-old canine jawbone at Hollembaek Hill near Delta Junction.

Chemical analysis revealed traces of salmon proteins in both bones, suggesting that these canines were fed fish by humans rather than hunting land animals as was typical for canines at that time. Ben Potter from the University of Alaska Fairbanks described this finding as "the smoking gun" indicating human dependence.

The study does not definitively establish these specimens as domesticated dogs but highlights their behavioral similarities to dogs due to their diet provided by humans. "Behaviorally, they seem to be like dogs," Lanoë noted.

This research continues a longstanding collaboration with tribal communities in Alaska's Tanana Valley. Josh Reuther from the University of Alaska Museum of the North emphasized presenting plans to local councils before conducting studies.

Evelynn Combs from Healy Lake Village expressed appreciation for respecting indigenous lands during research efforts. She highlighted her community's deep connection with dogs as mystic companions throughout history.

Combs reflected on her personal experience growing up with a dog named Rosebud: "I really love that we can look at the record and see that thousands of years ago, we still had our companions."
