David Reich

La extracción de ADN de los huesos de nuestros ancestros ha permitido resolver importantes controversias sobre la prehistoria, hasta el punto de cambiar su interpretación. Hoy en día puede extraerse y analizarse ADN antiguo y, en buena medida gracias a las aportaciones del propio David Reich, se ha puesto de manifiesto que la genómica es tan relevante como la arqueología o la lingüística a la hora de estudiar las poblaciones del pasado. En Quiénes somos y cómo hemos llegado hasta aquí, Reich nos enseña que el genoma humano, además de aportar toda la información que necesita un óvulo humano fertilizado para desarrollarse, contiene en sí mismo la historia de nuestra especie. La revolución de la genómica y del ADN antiguo está transformando lo que sabemos sobre el linaje de los humanos y, según nos explica Reich, los estudios de ADN revelan una larga historia de desigualdad entre poblaciones distintas, así como entre ambos sexos y entre individuos de una misma población. Esta obra desmiente la interpretación ortodoxa de que no hay diferencias biológicas relevantes entre poblaciones humanas y, al mismo tiempo, utiliza los sólidos datos de la genómica para ilustrar la improbabilidad de que las diferencias, que sí existen, se correspondan con los estereotipos de siempre.

The past few years have seen a revolution in our ability to map whole genome DNA from ancient humans. With the ancient DNA revolution, combined with rapid genome mapping of present human populations, has come remarkable insights into our past. This important new data has clarified and added to our knowledge from archaeology and anthropology, helped resolve long-existing controversies, challenged long-held views, and thrown up some remarkable surprises. The emerging picture is one of many waves of ancient human migrations, so that all populations existing today are mixes of ancient ones, as well as in many cases carrying a genetic component from Neanderthals, and, in some populations, Denisovans. David Reich, whose team has been at the forefront of these discoveries, explains what the genetics is telling us about ourselves and our complex and often surprising ancestry. Gone are old ideas of any kind of racial 'purity', or even deep and ancient divides between peoples. Instead, we are finding a rich variety of mixtures. Reich describes the cutting-edge findings from the past few years, and also considers the sensitivities involved in tracing ancestry, with science sometimes jostling with politics and tradition. He brings an important wider message: that we should celebrate our rich diversity, and recognize that every one of us is the result of a long history of migration and intermixing of ancient peoples, which we carry as ghosts in our DNA. What will we discover next?

A groundbreaking book about how ancient DNA has profoundly changed our understanding of human history. Geneticists like David Reich have made astounding advances in the field of genomics, which is proving to be as important as archeology, linguistics, and written records as a means to understand our ancestry. In Who We Are and How We Got Here, Reich allows readers to discover how the human genome provides not only all the information a human embryo needs to develop but also the hidden story of our species. Reich delves into how the genomic revolution is transforming our understanding of modern humans and how DNA studies reveal deep inequalities among different populations, between the sexes, and among individuals. Provocatively, Reich's book suggests that there might very well be biological differences among human populations but that these differences are unlikely to conform to common stereotypes. Drawing upon revolutionary findings and unparalleled scientific studies, Who We Are and How We Got Here is a captivating glimpse into humankind--where we came from and what that says about our lives today.
