New Ancient DNA study finds evidence of a large Medieval migration from Sweden to Finland

A new study published this autumn by Human Diversity researcher Ronan O’Sullivan et al. found that a larger migration from Sweden to Finland after the early Middle Ages played a large part on how the genetic makeup from coastal and inland southwestern Finland began to diverge. The study was also able to show how Finland was already closely connected to the Baltic Sea region from Early Medieval times. The research was published in Genome Biology.
