Current research suggests that the Ainu can be confidently linked to the Satsumon culture, who are believed to have displaced the epi-Jomon about AD 500; Satsumon may be a descendant of the Jomon rather than a replacement.
The Ainu are also considered by some scholars a strong candidate for the ancestral populations of some of the people who colonized the American continents, although geneticist Rebecca Cann has stated that there is no compelling evidence to support that.
