A genome screening study reveals that the Americas were peopled by at least three streams of migration from Asia. This sketch by Emiliano Bellini illustrates the findings of an initial peopling along a coastal route, followed by two subsequent Asian migrations that mixed with the first migrants to the Americas to give rise to a number of present-day North American populations. The drawings are based on photographs of Native Americans from the Arctic to Tierra del Fuego. Illustration: Emiliano Bellini. Alaska Dispatch.
