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."
