How many generations ago does it trace?
These tests trace both recent and very distant ancestry. All Y-DNA lineages from around the world can be traced to a single man who lived in Africa about 60,000 years ago, and all mtDNA lineages can be traced to a single woman who lived in Africa about 150,000 years ago. Your specific results can also be compared with the database to look for individuals with whom you share common ancestry within the last few centuries and, sometimes, generations.
