Poco a poco nos va llevando a lo que conocemos que es cierto hoy en día. Gracias claro a los estudios genéticos que se han realizados. Especialmente nos cuenta como a través del cambio en el adn mitocondrial en las mujeres y el adn en el cromosoma Y de los hombres se puede deducir que la especie humana se originó en Africa.
Una vez determinado nuestro punto de origen, Wells nos lleva desde Africa a todos los continentes, explicándonos como nos movimos de un sitio a otro, comprobando que esto que demuestra la genética también se corresponde a la evolución del lenguaje.

«Spencer Wells, whose genetic work has contributed to our understanding of human prehistory, has provided an acount of the spread and mixing of the human species from its origin in Africa that is both scientifically accurate and accessible to the nonscientist.» – Richard Lewontin (Hardvrd University, author of It Ain’t Necessarily So: The Dream of the Human Genome and Other Illusions)
Leading genetcist and explorer Spence Wells uses cutting-edge science to rewrite the fascinating story of our earliest ancestors – a companion to the PBS/National Geographic Special.
Around 60,000 years ago, a man-genetically indentical to us-lived in Africa. Every person alive today is descended from him. How did this real-life Adam wind up as the father of us all? What happaened to the descendants of other men who lived at the same time? And why, if moderm humans share a single prehistoric ancestor, do we come in so many sizes, shapes, and races?
Examining the hidden secrets of human evolution in our genetic code, Spencer Wells reveals how developments in the revolutionary science of population genetics have made it possible to create a family tree for the whole of humanity. Replete with marvelous anecdotes and remarkable information, from the truth about the real Adam and Eve to the way differing racial types emerged, The Journey of Man is an enthralling, epic tour thorugh the history and development of early humankind.
