We all want to know more about who we are. Who were the people who came before us? Where did they come from? Are there relatives out there we don’t know about?
DNA testing services promise to help answer these questions. Today, multiple at-home ancestry DNA kits can find long-lost relatives, estimate your ethnic ancestry, or show where your ancestors came from tens of thousands of years ago.
These tests are popular—according to the International Society of Genetic Genealogy (ISOGG), the number of people who bought at-home DNA kits now exceeds 18 million—and it’s easy to see why. All you have to do is swab your cheek or spit in a vial, seal your sample in a bag, and send it off to the lab. In a matter of weeks, you’ll be given a percentage breakdown of the regions your genes hail from.
