In The Seven Daughters of Eve Bryan Sykes has produced a highly readable scientific autobiography depicting the major events in his career as a human geneticist. He was the first to extract DNA from the bones of the 5,000-year-old Iceman, and he solved the problem of the colonisation of Polynesia by tracing modern Polynesians' genetic ancestry. The high point of his work so far is the creation of a genetic map of Western Europe, showing that over 95% of native Europeans can trace their ancestry back to one of seven individual women. To trace this lineage Sykes and his team used mitochondria, tiny structures within each cell, which are passed on purely down the maternal line. Because they do not engage in recombination like chromosomes, mitochondria are easy to trace, changing only as a result of slow mutation. The mutation rate acts as a clock indicating how long different populations have been separated. The science is clearly explained and Sykes gives a good flavour of the life of a working scientist in a series of well-chosen anecdotes, all written in a warm, engaging style. The seven daughters themselves, whom he has named Ursula, Xenia, Helena, Velda, Tara, Katrine and Jasmine, are brought to life in rather whimsical little stories describing how their lives might have been before and during the last great Ice Age. All in all, this is an excellent piece of popular-science writing, unveiling a fascinating story about human inter-relatedness. It deserves to be widely read. --Elizabeth Sourbut -- Dieser Text bezieht sich auf eine vergriffene oder nicht verfügbare Ausgabe dieses Titels.
Many of the stories concerning DNA and genetics are about the future - they're about what we can do tomorrow, which animals we can clone, which diseases we will be able to eradicate. This book is also about DNA, except it looks the other way, back across the sweep of time to the seven original women whose mitochondrial DNA - or "maternal" DNA if you like - is handed down from generation to generation and is still carried by everyone of European descent today. Sykes, who is Professor of Genetics at Oxford University, describes how he made this discovery in a book that is moving and inspiring and a world away from dry science. -- Dieser Text bezieht sich auf eine vergriffene oder nicht verfügbare Ausgabe dieses Titels.
A fascinating evaluation of our genetic origins. -- Dieser Text bezieht sich auf eine andere Ausgabe: Taschenbuch .
A scientist describes how he linked the DNA found in the remains of a five-thousand-year-old man to modern-day relatives and explains how all modern individuals can trace their genetic makeup back to prehistoric times to seven primeval women.
When Professor Bryan Sykes, a leading world authority on DNA and human evolution, was called in to examine the frozen remains of a man trapped in glacial ice in northern Italy five thousand years ago, it was the first lead in a fascinating scientific detective story. Remarkably, Professor Sykes was able to track down a living relative of the Ice Man in Britain.
How did he do this? The Seven Daughters of Eve is a first hand account of his research into an extraordinary gene which passes undiluted from generation to generation through the maternal line, allowing us to track our genetic ancestors through time and space. Professor Sykes has found that almost all Europeans can trace their ancestry back to one of seven women, whom he has named Ursula, Xenia, Helena, Velda, Tara, Katrine and Jasmine.
In this amazing scientific adventure story, we learn where our ancient genetic ancestors lived, what their lives were like and how every one of us is a testimony to the almost miraculous strength of our DNA. It is a book that not only re-examines the way we have evolved, but also addresses our sense of individuality and identity.-- Dieser Text bezieht sich auf eine andere Ausgabe: Taschenbuch .
Über den Autor und weitere Mitwirkende
is Professor of Human Genetics at the University of Oxford, has had a remarkable scientific career in genetics. After undertaking medical research into the causes of inherited bone disease, he set out to discover if DNA, the genetic material, could possibly survive in ancient bones. It did and he was the first to report on the recovery of ancient DNA from archaeological bone in the journal "Nature" in 1989. Since then Professor Sykes has been called in as the leading international authority to examine several high profile cases, such as the Ice Man, Cheddar Man and the many individuals claiming to be surviving members of the Russian Royal Family.
Alongside this, he and his research team have over the last ten years compiled by far the most complete DNA family tree of our species yet seen.He has always emphasised the importance of the individual in shaping our genetic world. The website www.oxfordancestors.com offers people the chance to find out for themselves, from a DNA sample, where they fit in.
As well as a scientist, Bryan Sykes has been a television news reporter and a parliamentary science adviser. He is the author of The Seven Daughters of Eve and Adam's Curse.-- Dieser Text bezieht sich auf eine andere Ausgabe: Taschenbuch .
