Children of Prometheus: The Accelerating Pace of Human Evolution (Helix Book) - Hardcover

Are we still evolving? Or has our mastery of the environment stopped natural selection in its tracks? In Children of Prometheus, biologist Christopher Wills gives a surprising answer: that the evolution of Homo sapiens is actually accelerating. To make this controversial case, Wills takes us to the far reaches of the planet. To the Tibetan plateau, where the severe climate has prompted rapid, short-term evolutionary change. To Africa, where human-caused ecological upheaval continues to spawn ever more virulent strains of infectious diseases - diseases which in turn affect the evolutionary course of their hosts. To the hushed corridors of Whitehall, where job stress is taking some British civil servants to an early death. In each of these cases - and in the many others that Wills examines - our power over nature has done nothing to halt evolution's unrelenting march. Spurred by a rapidly changing environment, and acting on our ever-expanding gene pool, natural selection will likely take us even deeper into uncharted territory. And Wills offers an exciting glimpse into this fascinating and frenetic future. What will become of our species as more and more of us wire our brains into vast electronic webs? Or pop "smart drugs" that alter the brain's very biochemical structure? Or adapt to bizarre conditions on extrasolar planets?

}Are we still evolving? Scientists have grappled with this question since the time of Darwin. Now, in this provocative book, biologist Christopher Wills argues that we are not only continuing to evolve but that our pace of change is accelerating. He examines the rapid, short-term evolutionary change taking place in people living at the earths extremes (even as babies, Tibetans can draw in more oxygen than lowlanders), and the new physiology of those who participate in extreme sports. But the more we shape our environment, the more it seems to shape us: Whether the future has us wiring our brains into vast electronic databases, or popping smart drugs that alter the brains very biochemical structure, new environmental pressures are speeding up our evolution in ways that we cannot now predict but that will help us to survive the future. }
