My mother is Scot and English and my dad had Spanish ancestry...that I suspect included Arab. My sisters and I have big dark eyes. But we all married men with blue eyes, like our mother, and all but one of us has children with blue eyes.
We’ve all ended up as good old American hodgepodge.
:’) Spanish ancestry pretty much always includes Arab, Berber, and whatever else came over during the Moslem Dark Ages (the occupation). I’ve got big eyes (although as I’ve chubbed out in my own personal medieval period, it’s more difficult to tell) as my dad did, and he was this really white guy, straight-line British Isles ancestry.
Which of course means, loads of everything. Europe, and the British Isles, have, like the rest of the world, seen its population altered by continual invasion. Going by the documentation available (which isn’t unique to Europe, but is vanishingly rare in most of the world, in particular the Americas) one would be tempted to think that Europe has been invaded more than anywhere on the planet. :’)
