Maybe some people knew but for me it is a shock that all early Swedish samples IA, despite an autosomal profile close to Nordic BA, had haplogroup N. Just as if the Finnish population, which probably reached Estonia around 660BC, conquered Scandinavia. Hence similar incidental samples in the Goths. Unless it was the Goths who underwent such a transformation on the continent and moved this line back to Sweden.
