Did you know that two of every three people reading this book will die for reasons connected with the genes they carry? That our DNA gradually changes with age, which is why older parents are more likely to give birth to children with genetic defects than younger parents? That each individual is a kind of living fossil, carrying within a genetic record that goes back to the beginnings of humanity? In The Language of Genes, renowned geneticist Steve Jones explores the meanings and explodes the myths of human genetics, offering up an extraordinary picture of what we are, what we were, and what we may become. Steve Jones's highly acclaimed, double prize-winning, bestselling first book is now fully revised to cover all the new genetic breakthroughs from GM food to Dolly the sheep.
