I learned from a documentary many years ago about the DNA tracing of human migration. The DNA scheme is based on the assumption that people don't migrate everywhere but tend to stay in one place. This allows you to statistically associate DNA markers with regional areas from the individual profiles provided by the people sampled. Still, other factors, such as historical facts and folk legends, must be brought in to corroborate the statistics.

In the documentary, they tracked down a man in Kazakstan who was the descendant of two thousand generations of the unknown man who spawned these human migrations in all directions to Europe, Asia, and beyond. I'm sure that theory has since been refined.
The funny part was the scientists went to meet this guy, and he was fearful that they had found something in his blood and that he was terminally ill. I think it was a National Geographic documentary.
I remember watching that.
About migration, my ancestors migrated. My paternal grandfather lived 10538 miles (16969 km) from his birthplace; my parents were born within about 124 miles (200 km) where my grandparents lived. My parents immigrated, and my siblings and I with them, and I now live 10364 miles (16688 km) from where I was born. Going back to 3rd great grandparents, and earlier, most probably stayed within the region where they were born, but some migrated within the UK.
From DNA tests, I find relatives scattered throughout the UK and former colonies, Canada, US, Australia and NZ, and some scattered throughout EU, Asia and Africa, but none so far in S. America. My ancestors are mostly from N. England, Scotland, Wales, with some from Ireland (probably Scottish/Welsh origin) and S. England (Cornwall, Devon, Hampshire). There is some Germanic Eu (Angles & Saxons), as well as bits of Danish/Sweden (Viking), but not so much Norwegian.
My wife is related to eight persons (including two 8th great grandparents and two 10th great grandparents) from the original Mayflower, which departed Plymouth, England landed at what is now Plymouth, Massachusetts, US, as well as subsequent voyages/ships from England. My wife's paternal side has a lot of French Canadians, and her maternal side has some Irish and NE US.
In the original Mayflower population, about one-half were religious dissenters, and the other half were entrepreneurs; all were headed to Virginia colony, but weather forced them toward what became Massachusetts Colony.
Another resource on the Basque people.

I'm also curious about Sardinia. Some ancestry showed in my wife's DNA.
