The Trouble with Ancient DNA: Telling Stories of the Past with Genomic Science

A thoughtful consideration of the storytelling and science behind ancient DNA discoveries.

In recent years, discoveries brought to light through analysis of ancient DNA—or aDNA—have made headlines around the world. While ancient DNA studies may appear to focus on laboratory science and objective results, the findings have also relied heavily on storytelling and can be influenced by political interests.

In The Trouble with Ancient DNA, Anna Källén explores how the parameters of genetic science influence the stories we tell about our ancient ancestors, questioning what narratives we can and should take at face value. Through accounts of migrations, warriors, and figures like Cheddar Man, we see enticing and potent narratives that reach far beyond what can be gathered from the scientific study of molecules alone. Rather, by privileging certain narratives and questions—like those about sex or eye and skin color—our stories of ancient DNA are spun around the structure of today’s methodologies, technologies, and popular and political interests. Källén considers how DNA is used to sensationalize stories, how its use poses questions of ethics and care, and who is responsible if stories of ancient DNA are adopted for dangerous political projects.
