Synopsis

There have been five great extinctions in the long history of life on earth, the most recent 65 million years ago, when all dinosaur species perished in an astonishingly brief period of time. Each of these great extinctions was unimaginably catastrophic - at least 65 percent of all species living vanished in a geological instant; in the Permian extinction, nearly 95 percent of all species were obliterated. The agency for these extinctions, the why, is hotly debated - sudden climate change, asteroids, evolutionary inadequacy - but the patterns are remarkably consistent. Now, as Leakey and Lewin show with inarguable logic based on irrefutable scientific evidence, the sixth great extinction is underway. And this time the cause is beyond dispute: By the lowest estimate, thirty thousand species are wiped out by human agency every year - a rate that matches the patterns of the other five great extinctions with frightening exactitude. As the authors show, such dramatic and overwhelming extinction threatens the entire complex fabric of life on earth, including the species at fault, Homo sapiens. Unless we come to realize the devastating consequence of our rapacious behavior, we will follow the mastodon, the great auk, the carrier pigeon, and our other victims into the oblivion of extinction.

About the Author

Richard Leakey is the world's most famous living paleoanthropologist. He resigned from his position as chairman of the National Museums of Kenya when Kenya's president, Daniel arap Moi appointed him to head the Kenya Wildlife Service. His parents were the archaeologists Louis Leakey and Mary Leakey. His half-brother is the leading plant scientist, Colin Leakey.

Roger Lewin, PhD, is a biochemist, the former deputy editor of the British magazine New Scientist, and the author of Making Waves: Irving Dardik and His Superwave Principle, as well as many other highly praised books on biology such as Complexity: Life at the Edge of Chaos and Patterns in Evolution: The New Molecular View.

From the Inside Flap

"Richard Leakey, One Of The World's Foremost Experts On Man's Evolutionary Past, Now Turns His Eye To The Future And Doesn't Like What He Sees.
To the philosophical the earth is eternal, while the human race -- presumptive keeper of the world's history -- is a mere speck in the rich stream of life. It is known that nothing upon Earth is forever; geography, climate, and plant and animal life are all subject to radical change. On five occasions in the past, catastrophic natural events have caused mass extinctions on Earth. But today humans stand alone, in dubious distinction, among Earth's species: "Homo Sapiens possesses the ability to destroy entire species at will, to trigger the sixth extinction in the history of life. In "The Sixth Extinction, Richard Leakey and Roger Lewin consider how the grand sprawl of human life is inexorably wreaking havoc around the world. The authors of "Origins and "Origins Reconsidered, unimpeachable authorities on the human fossil record, turn their attention to the most uncharted anthropological territory of all: the future, and man's role in defining it. According to Leakey and Lewin, man and his surrounding species are end products of history and chance. Now, however, humans have the unique opportunity to recognize their influence on the global ecosystem, and consciously steer the outcome in order to avoid triggering an unimaginable upheaval.
