Whether or not family history interests you, it’s hard to escape the recent surge in advertising for genealogy-driven DNA tests, particularly the service offered by genealogy giant Ancestry. Ancestry has been heavily promoting this service through both online ads and television commercials, and it represents a fascinating development for family historians who can now use genetic information to find distant or sparsely documented relatives. However, the main thrust of the ad campaigns has not been to advertise the research benefits of DNA, but to appeal to a search for identity and belonging through our connections to ethnic communities. This introduces a number of problematic ideas around the intersection of genetics, personal identity, and racism. Does DNA really help you find out who you are? And does finding “who you are” entitle you to belong to a community that has never embraced you as a member?
DNA testing services are nothing new, and they all follow the same basic formula: spit into a test tube, pay a processing fee, ship the sample and wait for your results to arrive. These results usually take the form of basic ethnicity and health indicators as well as genetic predispositions towards various diseases. The fresh appeal of genealogy-driven services like Ancestry DNA lies in their databases, which compare every test to all other users in order to identify relatives. This has the potential to reveal previously unknown ancestors or confirm relationships that may have only been guessed at. It’s an exciting new option for genealogists who want to supplement their existing research.
However, the advertising campaigns for these DNA tests appeals more to a quest for identity than to the potential research benefits. This shift in emphasis from documentary evidence to genetics represents a dramatic shift in Ancestry’s marketing. The cornerstone of Ancestry’s empire (and indeed a primary motivation for most genealogists and family historians) has been the concept that knowing who you are comes from your connection to the past and from finding the stories of your ancestors in archival documents. Recent advertising flips this on its head to suggest that knowing who you are comes not from painstaking research, but from discovering your genetic makeup. In other words, genetic information is a marker not only of biological identity, but of personal identity. Continue reading
