What hat do you wear with a kilt?

BTW, the whole idea of the Gaels populating Scotland from Ireland comes from a legend, and evidence shows that there was a constant flux of peoples going back and forth, settling and moving on, all around the area.

Excellent post there!

Yes indeed for hundreds (if not thousands) of years our concept of early peoples has been based on the "invasion hypothesis" (whether openly stated or not), so much so that it underlies much of our thinking and is taken for granted.

So the history of peoples (anywhere on earth) has always been stuff like "so-and-so invaded first, then so-and-so invaded next, and then so-and-so invaded next" and so on.

All of this invading has been undergoing a reevaluation in recent decades and currently the "invasion hypothesis" is not so much in fashion. (Except with Marija Gimbutas and her followers, the Kurgans and all that.)
