you're talking about a change that occurred over several hundred years from migration from central europe, probably from the eurasian steppe prior and to call it a "wipe out" isn't fair. we are talking about migrations of people within europe itself which makes it all rather a moot point. the non moot point is that op is a retard if he thinks we aren't closely related to our european brothers. go and do a 23 and me and you'll likely see scandi dna and the reason for that isn't some cucky reason like chad vikings reamed great grammy it's because we are inherently linked over thousands of years of migration. which one of these nations had the best empire though...
