Study finds humans and dogs formed close bonds 12,000 years ago in the Americas, earlier than thought.

A new study in Science Advances reveals that humans and dogs formed close relationships around 12,000 years ago in the Americas, about 2,000 years earlier than previously known. Researchers found a 12,000-year-old canine bone in Alaska with signs of a salmon-based diet, indicating human-provided food. This discovery, from the Swan Point site, suggests early domestication or taming of wolves, but the genetic link to later dog populations is unclear.
