Our identity, both personal and collective, is a fluid and complex narrative often rooted in the past. This past can now be explored with new technological developments; in the last few years, more than 12,000 ancient human genomes have been retrieved. At the same time, ancestry test companies are building conceptions on our identity based on genetic data from literally tens of millions of customers. Computational approaches are now able to generate pedigrees with literally millions of people across tens of generations.

In Identity, Carles Lalueza-Fox explores how the unprecedented amount of genetic information generated in the last ten years can provide meaningful and fascinating evidence about our identity, starting at the individual level and ending at the species level.

As genetics take center stage as a social transformative tool in the twenty-first century, this book helps explain the tremendous impact it will have on our concept of identity.
