The interesting part is that my son's paternal haplogroup is R1b1b2a1a1* (which would be the LUCIER line).
Today R1b1b2a1a1 is found mostly on the fringes of the North Sea in England, Germany and the Netherlands, where it reaches levels of one-third. That distribution suggests that some of the first men to bear the haplogroup in their Y-chromosomes were residents of Doggerland, a real-life Atlantis that was swallowed up by rising seas in the millennia following the Ice Age. Doggerland was a low-lying region of forests and wetlands that must have been rich in game; today, fishing trawlers in the North Sea occasionally dredge up the bones and tusks of the mastodons that roamed there. Doggerland had its heyday between about 12,000 years ago, when the Ice Age climate began to ameliorate, and 9,000 years ago, when the meltwaters of the gradually retreating glaciers caused sea levels to rise, drowning the hunter's paradise. Doggerland's inhabitants retreated to the higher ground that is now the North Sea coast.
