I really do not care for genealogical genetics. I believe they promise you conclusions based on dubious assumptions so that you'll feel a sense of belonging, when most people, including myself, don't understand the intricacies that can go into genetics beyond simple Mendelian inheritance. I don't think the conclusions they reach regarding people are any better than the companies who purport to tell you what breed your dog is. Beyond that, there is the matter of how utterly stupid it is to freely give a for-profit company your genetic material that they may monetise later.
Population genetics are a different matter, though, so I find this fascinating, and I loved the following quote:
In any given population, the number of lines in your family tree that reach any specific medieval person is about the same between you and everyone else who belongs to the same population you do. In other words, everyone alive today is equally related, genealogically, to all medieval people from that population.>In any given population, the number of lines in your family tree that reach any specific medieval person is about the same between you and everyone else who belongs to the same population you do.

DNA says you’re related to a Viking, a medieval German Jew or a 1700s enslaved African? What a genetic match really means
