Who are our ancestors? Where did they come from? Geneticists have suddenly become historians, and the hard evidence in our DNA has blown the lid off what we thought we knew. Acclaimed science writ…

New genetic technologies are transforming the way we live and promise treatments for otherwise incurable diseases. But these advances are also generating controversy, particularly surrounding issues such as cloning and designer babies. In 50 Genetics Ideas, Mark Henderson distils the central ideas of…
