Showing results for "Matt Ridley" in Evolution & Genetics

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.

Genome unravels the secrets of human nature without the usual reams of technical jargon. It shows outstanding breakthroughs in gene research, how we've gone from knowing almost nothing to knowing almost everything, and how our genes reveal more about our past, our evolution, and even our minds. Every important event in human history is written into our genes, whether it happened four billion or a few hundred years ago. All you need to know is where to look.

In all animals, mating is a deal. But few creatures behave as if sex is a simple transaction. Many treat it with reverence, suspicion, angst and violence. In the case of the Black Grouse, the bird at the center of Matt Ridley’s investigation, the males dance and sing for hours a day, for several exhausting months, in an exhausting and sometimes deadly ritual called a ‘lek’. 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 .
