DNA may hold clues to an ancient movement from Ireland to Scotland
Scientific evidence of an ancient invasion of Scotland from Ireland may have been uncovered by DNA techniques. ............
Early historical sources recount how the Gaels came from Ireland about 500 AD and conquered the Picts in Argyll. ...............................

Scientists said the study was the first demonstration of a significant Irish genetics component in Scots' ancestry.
I don't mean to be obtuse, or argumentative, but isn't it already known that peoples moved back and forth? Didn't we already know that the Scoti came from Dalraida (Northern Ireland) Is this DNA evidence, that the Scottish Celts and Irish Celts are related, really any surprise?
