Descrizione dell’editore
The national bestseller that reveals how we are descended from seven prehistoric women.
In 1994 Bryan Sykes was called in as an expert to examine the frozen remains of a man trapped in glacial ice in northern Italy for over 5000 years—the Ice Man. Sykes succeeded in extracting DNA from the Ice Man, but even more important, writes Science News, was his "ability to directly link that DNA to Europeans living today." In this groundbreaking book, Sykes reveals how the identification of a particular strand of DNA that passes unbroken through the maternal line allows scientists to trace our genetic makeup all the way back to prehistoric times—to seven primeval women, the "seven daughters of Eve."
PUBLISHERS WEEKLY
"A traveler from an antique land... lives within us all," claims Sykes, a professor of genetics at Oxford. This unique traveler is mitochondrial DNA, and, as this provocative account illustrates, it can help scientists and archeologists piece together the history of the human race. Mitochondrial DNA is present in every cell in the body, and it remains virtually unchanged (aside from random mutations) as it passes from mother to daughter. By quantifying and analyzing the mutations of this relatively stable circle of DNA, Sykes has solved some of the hottest debates about human origins. For example, he clarified a long-running debate among anthropologists over the original inhabitants of the Cook Islands. After retrieving mitochondrial DNA samples from the island natives, Sykes concluded that the natives emigrated from Asia, not America, as many Western anthropologists had contended. In a similar manner, Sykes analyzed samples from native Europeans to determine that modern humans are not at all related to Neanderthals. The book's most complex and controversial find that the ancient European hunter-gatherers predominated over the farmers and not vice versa leads Sykes to another stunning conclusion: by chance, nearly all modern Europeans are descendants of one of seven "clan mothers" who lived at different times during the Ice Age. Drawing upon archeological and climatic records, Sykes spins seven informative and gracefully imagined tales of how these "daughters of Eve" eked out a living on the frozen plains.
