Study reveals that humans reached remote North Atlantic islands centuries earlier than thought

In a study published in Communications Earth & Environment, Ray Bradley and colleagues, including former CSRC postdoctoral researcher William D’Andrea at Columbia University, suggest that an unknown band of humans settled there around A.D. 500 — some 350 years before the Vikings, who until recently were thought to be the first human inhabitants. The study is supported by lake sediment samples containing signs that domestic sheep suddenly appeared around 500, well before the Viking occupation.
