François Lanoë, an assistant research professor at the University of Arizona's School of Anthropology, helped uncover an 8,100-year-old canine jawbone in interior Alaska in June 2023. Alongside a 12,000-year-old leg bone found nearby, these discoveries provide some of the earliest evidence of close relationships between ancient dogs, wolves, and humans in the Americas.
