Identidad : Qué nos dice el ADN sobre quiénes somos

What does it truly mean to have an identity? How far does our self-perception extend, and what role does our DNA play in that construction? In *Identity*, Carles Lalueza-Fox addresses one of the most complex and pressing questions of our time from a rigorous scientific and profoundly humanistic perspective. Drawing on the latest advances in genomics and paleogenetics, the author explores how genetic information illuminates different levels of human identity: individual, familial, collective, and ultimately, that of the species itself. Throughout the book, he dismantles widespread ideas about race, genetic purity, and the existence of fixed biological identities, demonstrating the extent to which our identities are the result of continuous mixing, historical migrations, and invisible ties that connect us to millions of people from the past and present. With examples ranging from European kings to ancient genomes, from commercial DNA tests to contemporary debates on gender, belonging, and nationalism, Identity offers an essential reflection on the limits and possibilities of genetics in explaining who we are, and on the risks of using it in a simplistic or ideological way.
