Over 10,000 years ago there were fewer than 10 million people on the planet. Today there are more than six billion, 99 per cent of whom are better fed, better sheltered, better entertained and better protected against disease than their Stone Age ancestors. Yet, bizarrely, however much things improve from the way they were before, people still cling to the belief that the future will be nothing but disastrous.

To prepare for the ordeal, they grow, preen and display fancy, twisted, bold-colored feathers.

How could a relatively simple chemical code give rise to the complexity of a human being? How could our human genome have evolved? And how does it actually work? Your genome defines you at the most profound level. That same genome is present in every one of the approximately 100,000 billion cells that make you who you are as an individual member of the human species. An important ingredient of the genome, and its essential nature, is memory .
