Abstract

Spectacular advances in genetic technology in the past couple of decades have revolutionised our understanding of how different parts of the globe came to be occupied by Homo sapiens. We now have evidence that Homo sapiens evolved in Africa between 300,000 and 150,000 years ago; successfully dispersed out of Africa between 100,000 and 70,000 years ago; reached Central Asia (including India), Europe and Australia some 65,000 years ago; and reached the Americas about 16,000 years ago. All present-day humans worldwide can thus be traced back to Africa, and their current distribution can be accounted for by a single episode of dispersal out of Africa. We are also rapidly obtaining new and equally surprising information about many subsequent dispersals from one region to another outside Africa. These findings and conclusions have captured the public imagination for two reasons. One is the amazing new technology and what we can do with it. Today, we can sequence and compare mitochondrial DNA, which is passed on unshuffled and only along the female line and thus trace every living person back to the so-called mitochondrial Eve who lived in Africa over 70,000 years ago. We can also sequence and compare the Y chromosome, which is also passed on (almost) unshuffled but, in this case, only along the male line, a technique that can trace everyone back to the so-called African Adam and reconfirm the story told by the mitochondrial DNA.
