Following the developments of mitochondrial genetics, Sykes traces back human migrations, discusses the Out Of Africa Theory and refutes Heyerdahl 's theory of the Peruvian origin of the Polynesia ns, opposing an Indonesian origin. He also describes the use of mitochondrial DNA in identifying the remains of Czar Nicholas II , and in assessing the genetic makeup of modern Europe. The title of the book comes from one of the principal achievements of mitochondrial genetics, which is the classification of all modern humans into '' Mitochondrial Haplogroups ''. Each haplogroup is defined by set of characteristic mutations on the mitochondrial genome, and can be traced along a person's maternal line to a specific prehistoric woman. Sykes refers to these women as "clan mothers", though these women did not all live concurrently, and indeed some "clan mothers" are descended from others. All these women in turn shared a common ancestor, the so-called Mitochondrial Eve . Sykes claims there are seven mitochondrial lineages for modern Europe ans (though others put the number at 11 or 12) and he therefore speaks of the "Seven Daughters of Eve". The number of mitochondrial lineages for the entire human population (rather than just for Europeans) is considerably larger. The second half of the book is spent on a series of fictional narratives, written by Sykes, describing his creatives guesses about the lives of each of these seven "clan mothers". This latter half generally met with mixed reviews in comparison with the first part. MITOCHONDRIAL HAPLOGROUPS IN ''THE SEVEN DAUGHTERS OF EVE'' The seven "clan mothers" mentioned by Sykes each correspond to one (or more) human mitochondrial haplogroups.
