The Seven Daughters Of Eve
''The Seven Daughters of Eve'' is a 2001 semi-fictional book by Bryan Sykes that presents the science of human origin in Africa and their dispersion to a general audience. Sykes explains the principles of genetics and human evolution, the particularities of mitochondrial DNA, and analyses of ancient DNA to genetically link modern humans to prehistoric ancestors. Following the developments of mitochondrial genetics, Sykes traces back human migrations, discusses the " out of Africa theory" and casts serious doubt upon Thor Heyerdahl's theory of the Peruvian origin of the Polynesians, which opposed the theory of their origin in Indonesia. He also describes the use of mitochondrial DNA in identifying the remains of Emperor Nicholas II of Russia, 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 Europeans into seven groups, the '' mitochondr ...

Bryan Sykes
Bryan Clifford Sykes (9 September 1947 – 10 December 2020) was a British geneticist and science writer who was a Fellow of Wolfson College and Emeritus Professor of Human Genetics at the University of Oxford. Sykes published the first report on retrieving DNA from ancient bone (''Nature'', 1989). He was involved in a number of high-profile cases dealing with ancient DNA, including that of Ötzi the Iceman. He also suggested a US accountant named Tom Robinson was a direct descendant of Genghis Khan, a claim that was subsequently disproved. Sykes is best known outside the community of geneticists for his two popular books on the investigation of human history and prehistory through studies of mitochondrial DNA. Education Sykes was educated at Eltham College, received his BSc from the University of Liverpool, his PhD from the University of Bristol, and his DSc from the University of Oxford.

Haplogroup V (mtDNA)
Haplogroup V is a human mitochondrial DNA (mtDNA) haplogroup. The clade is believed to have originated over 14,000 years ago in Southwestern Europe. Origin Haplogroup V derives from the HV0a subclade of haplogroup HV. In 1998 it was argued that V spread over Europe from an Ice Age refuge in Iberia. However more recent estimates of the date of V would place it in the Neolithic. Distribution Haplogroup V is a relatively rare mtDNA haplogroup, occurring in around 4% of native Europeans. Its highest concentration is among the Saami people of northern Fennoscandia (~59%). It has been found at a frequency of approximately 10% among the Maris of the Volga-Ural region, leading to the suggestion that this region might be the source of the V among the Saami. Haplogroup V has been observed at higher than average levels among Cantabrian people (15%) of northern Iberia, and among the adjacent Basque (10.4%). Haplogroup V is also found in parts of Northwest Africa. It is mainly concentrated ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Haplogroup
A haplotype is a group of alleles in an organism that are inherited together from a single parent, and a haplogroup (haploid from the , ''haploûs'', "onefold, simple" and ) is a group of similar haplotypes that share a common ancestor with a single-nucleotide polymorphism mutation. More specifically, a haplotype is a combination of alleles at different chromosomal regions that are closely linked and tend to be inherited together. As a haplogroup consists of similar haplotypes, it is usually possible to predict a haplogroup from haplotypes. Haplogroups pertain to a single line of descent. As such, membership of a haplogroup, by any individual, relies on a relatively small proportion of the genetic material possessed by that individual. Each haplogroup originates from, and remains part of, a preceding single haplogroup (or paragroup). As such, any related group of haplogroups may be precisely modelled as a nested hierarchy, in which each set (haplogroup) is also a subset of a si ...

Haplogroup N1 (mtDNA)
Haplogroup N is a human mitochondrial DNA (mtDNA) clade. A macrohaplogroup, its descendant lineages are distributed across many continents. Like its sibling macrohaplogroup M, macrohaplogroup N is a descendant of the haplogroup L3. All mtDNA haplogroups found outside of Africa are descendants of either haplogroup N or its sibling haplogroup M. M and N are the signature maternal haplogroups that define the theory of the recent African origin of modern humans and subsequent early human migrations around the world. The global distribution of haplogroups N and M indicates that there was likely at least one major prehistoric migration of humans out of Africa, with both N and M later evolving outside the continent. Origins There is widespread agreement in the scientific community concerning the African ancestry of haplogroup L3 (haplogroup N's parent clade). However, whether or not the mutations which define haplogroup N itself first occurred within Asia or Africa has been a subject ...

Haplogroup W (mtDNA)
Haplogroup W is a Human mitochondrial DNA haplogroup, human mitochondrial DNA (mtDNA) haplogroup. Origin Haplogroup W is believed to have originated around 23,900 years ago in Western Asia. It is descended from the Haplogroup N (mtDNA), haplogroup N2. Distribution Haplogroup W is found in Europe, Western Asia, and South Asia. It is widely distributed at low frequencies, with a high concentration in Northern Pakistan. Haplogroup W is also found in the Maghreb among Algerians (1.08%-3.23%)S5 Table/ref> and in Siberia among Yakuts (6/423 = 1.42%Sardana A Fedorova, Maere Reidla, Ene Metspalu, ''et al.'', "Autosomal and uniparental portraits of the native populations of Sakha (Yakutia): implications for the peopling of Northeast Eurasia."

Haplogroup M (mtDNA)
Haplogroup M is a human mitochondrial DNA (mtDNA) haplogroup. An enormous haplogroup spanning all the continents, the macro-haplogroup M, like its sibling the macro-haplogroup N, is a descendant of the haplogroup L3. All mtDNA haplogroups considered native outside of Africa are descendants of either haplogroup M or its sibling haplogroup N. Haplogroup M is relatively young, having a younger most recent common ancestor date than some subclades of haplogroup N such as haplogroup R. Origins There is a debate concerning the geographical origins of Haplogroup M and its sibling haplogroup N. Both lineages are thought to have been the main surviving lineages involved in the out of Africa migration (or migrations) because all indigenous lineages found outside Africa belong to haplogroup M or haplogroup N. Scientists are unsure whether the mutations that define haplogroups M and N occurred in Africa before the exit from Africa or in Asia after the exit from Africa. Determining th ...

Haplogroup I (mtDNA)
Haplogroup I is a human mitochondrial DNA (mtDNA) haplogroup. It is believed to have originated about 21,000 years ago, during the Last Glacial Maximum (LGM) period in West Asia ; ; ). The haplogroup is unusual in that it is now widely distributed geographically, but is common in only a few small areas of East Africa, West Asia and Europe. It is especially common among the El Molo and Rendille peoples of Kenya, various regions of Iran, the Lemko people of Slovakia, Poland and Ukraine, the island of Krk in Croatia, the department of Finistère in France and some parts of Scotland and Ireland. Origin Haplogroup I is a descendant (subclade) of haplogroup N1a1b and sibling of haplogroup N1a1b1 . It is believed to have arisen somewhere in West Asia between 17,263 and 24,451 years before present (BP) , with coalescence age of 20.1 thousand years ago . It has been suggested that its origin may be in Iran or more generally the Near East . It has diverged to at least seven distinct cl ...

Haplogroup K (mtDNA)
Haplogroup K, formerly Haplogroup UK, is a human mitochondrial DNA (mtDNA) haplogroup. It is defined by the HVR1 mutations 16224C and 16311C. It is now known that K is a subclade of U8. Origin Haplogroup K is believed to have originated in the mid-Upper Paleolithic, between about 30,000 and 22,000 years ago. It is the most common subclade of haplogroup U8b. Distribution Haplogroup K appears in Central Europe, Southern Europe, Northern Europe, North Africa, the Horn of Africa, South Asia and West Asia and in populations with such an ancestry. Overall the mtDNA haplogroup K is found in about 6% of the population of Europe and the Near East, but it is more common in certain populations. In Europe, K appears to be most common in the Morbihan (17.5%) and Périgord-Limousin (15.3%) regions of France, and in Norway and Bulgaria (13.3%). The level is 12.5% in Belgium, 11% in Georgia and 10% in Austria and Great Britain.Lucia Simoni, Francesc Calafell, Davide Pettener, Jaume Bertran ...

Haplogroup T (mtDNA)
Haplogroup T is a human mitochondrial DNA (mtDNA) haplogroup. It is believed to have originated around 25,100 years ago in the Near East. Origins Mitochondrial clade T derives from the haplogroup JT, which also gave rise to the mtDNA haplogroup J. The T maternal clade is thought to have emanated from the Near East. Distribution The basal haplogroup T* is found among Algerians in Oran (1.67%) and Reguibate Sahrawi (0.93%).S5 Table/ref> It is also distributed among the Soqotri (1.2%). Haplogroup T is present at low frequencies throughout Western and Central Asia and Europe, with varying degrees of prevalence and certainly might have been present in other groups from the surrounding areas. T is found in approximately 10% of native Europeans. It is also common among modern day Iranians. Based on a sample of over 400 modern day Iranians, the T haplogroup represents roughly 8.3% of the population (about 1 out of 12 individuals), with the more specific T1 subtype constituting ...

Scandinavia
Scandinavia is a subregion#Europe, subregion of northern Europe, with strong historical, cultural, and linguistic ties between its constituent peoples. ''Scandinavia'' most commonly refers to Denmark, Norway, and Sweden. It can sometimes also refer to the Scandinavian Peninsula (which excludes Denmark but includes a part of northern Finland). In English usage, Scandinavia is sometimes used as a synonym for Nordic countries. Iceland and the Faroe Islands are sometimes included in Scandinavia for their Ethnolinguistics, ethnolinguistic relations with Sweden, Norway and Denmark. While Finland differs from other Nordic countries in this respect, some authors call it Scandinavian due to its economic and cultural similarities. The geography of the region is varied, from the Norwegian fjords in the west and Scandinavian mountains covering parts of Norway and Sweden, to the low and flat areas of Denmark in the south, as well as archipelagos and lakes in the east.
