You Are Your DNA

A bold, evidence-based exploration of how our DNA shapes who we are: psychologically, socially, and biologically.

You Are Your DNA reveals the profound role that our genetic code plays in building not only our bodies, but our minds, our personalities, and the very sense of who we are. Written by two of Spain’s leading behavioral geneticists—Roberto Colom and Juan Ramón Ordoñana—this book draws on the latest scientific evidence to show how the instructions encoded in our DNA lay the foundation for our individuality, shaping how we think, feel, and behave from the moment of conception.

Far from offering a deterministic view, the authors emphasize the dynamic interplay between nature and nurture. While our genome provides the blueprint, it is our life experience—from the prenatal environment to the challenges of adulthood— that determines how that code is expressed. With clarity and scientific rigor, they dismantle lingering taboos in the social sciences and argue that understanding our genetic foundations is not only compatible with, but essential to, truly knowing ourselves.

Provocative and illuminating You Are Your DNA sits at the intersection of biology, psychology, and philosophy. It challenges readers to reconsider long-standing beliefs about identity, free will, and the biological roots of human behavior—offering a bold, evidence-based lens through which to understand ourselves more clearly.

Since time immemorial, humans have pursued the wise advice 'Know thyself'. Yet one crucial piece has long been missing: the scientific exploration of the foundations of our psychological structure —our genomes.
