Groups isolated on islands wind up with the same last name. It’s just how it winds up. The isolation concentrates and speeds up a process that is going on everywhere, but goes on mostly invisibly. Blue eyes are just easy to spot. A similar study would show common ancestry for everyone with kinky hair, or (perhaps) a given blood type (such as B, which is the least common major bloodtype; AB people would also have their B gene on chromosome 9 tested). This blue eye study is probably not done for political purposes, but will surely be twisted into such purposes.
