Oldest domestic dog remains in Americas

A tooth found in caves in Haida Gwaii in Canada is the earliest reported remains of a domestic dog in the Americas. Radiocarbon dating pinpoints the tooth’s age to 13,100 years ago — the oldest archæological evidence of human occupation in the area by 2,000 years. The findings stand alongside oral histories that record the Haida people’s long history on the islands. Researchers predict more discoveries to come, because the caves on the west coast of Canada are mostly unexplored by archæologists.
