Stephen Oppenheimer had a de-linking moment for the Scots and the Finns similar to this in his book, "Origins Of The British".
He says that the people on either side are so closely related genetically that they must have been one big family before the split

by scots, do they mean the picts, or, given the timeline, the genetic group that would become picts in eastern scotland?

you mean Scots (Scotti from Ireland) are related to Gaels (highlanders) are related to the Norse invaders and to the Finns?

The water hasn’t been much of a barrier — that’s why the populations are so similar. The UK runs on myth more than most countries. But then again, besides the Glorious Revolution, the Norman Conquest, the Danes, the Angles/Saxons/Jutes, the Romans, the Q-Celts, the P-Celts, and the groups described in the Book of Invasions, there’s hardly ever been a successful migration into the British Isles. ;’)
