A total of 1,664 new mtDNA control-region sequences were analyzed in order to estimate Gaelic and Scandinavian matrilineal ancestry in the populations of Iceland, Orkney, the Western Isles, and the Isle of Skye and to investigate other aspects of their genetic history. A relative excess of private lineages in the Icelanders is indicative of isolation, whereas the scarcity of private lineages in Scottish island populations may be explained by recent gene flow and population decline.

Figures and Tables from this paper

The origin of the isolated population of the Faroe Islands investigated using Y chromosomal markers

It is hypothesised that the high degree of Y chromosome similarity between the two populations arose because they were colonised at approximately the same time by males originating from the same regions of Scandinavia and, to a lesser extent, from the British Isles.

Highly discrepant proportions of female and male Scandinavian and British Isles ancestry within the isolated population of the Faroe Islands

Compared to other admixed populations of the North Atlantic region, the population of the Faroe Islands appears to have the highest level of asymmetry in Scandinavian vs British Isles ancestry proportions among female and male settlers of the archipelago.

Genetic Structure and Origin of Peopling in The Azores Islands (Portugal): The View from mtDNA

To improve the genetic characterisation of the Azorean population, and to clarify some aspects related to the history of settlement, a study of mtDNA was conducted in the population of the archipelago.

Tracing the phylogeography of human populations in Britain based on 4th-11th century mtDNA genotypes.

The history of migration by women by amplifying mitochondrial DNA from ancient Britons who lived between approximately A.D. 300-1,000 is investigated and evidence for shared ancestry between the earliest sites (predating Viking invasions) with modern populations across the north of Europe from Norway to Estonia is found.

Traces of early Eurasians in the Mansi of northwest Siberia revealed by mitochondrial DNA analysis.

The added presence of eastern Eurasian mtDNA lineages in the Mansi introduces the possibilities that proto-Eurasians encompassed a range of macrohaplogroup M and N lineages that subsequently became geographically distributed and that the Paleolithic expansion may have reached this part of Siberia before it split into western and eastern human groups.

Mitochondrial DNA affinities at the Atlantic fringe of Europe.

Mitochondrial DNA analysis of Atlantic European samples has detected significant latitudinal clines for several clusters with Paleolithic and Neolithic coalescence ages in Europe, and it is proposed that a pre-Neolithic origin for this gene flow is proposed.

Matrilineal diversity and population history of Norwegians.

This analysis of mtDNA diversity within Norway provides a detailed picture of the genetic variation within Norway in light of its topography, settlement history, and historical migrations over the past several centuries.

Mitochondrial DNA variation of modern Tuscans supports the near eastern origin of Etruscans.

Interpopulation comparisons reveal that the modern population of Murlo, a small town of Etruscan origin, is characterized by an unusually high frequency (17.5%) of Near Eastern mtDNA haplogroups, supporting a direct and rather recent genetic input from the Near East--a scenario in agreement with the Lydian origin of ETruscans.

Mitochondrial DNA polymorphism in populations of aboriginal residents of the Far East

The presence of East Eurasian haplogroups A and D with a strong predominance of haplogroup A in Chukchi indicates the closer relationship of this population both with Asian and Canadian Eskimos and northern Atapasks on the other side of Bering Strait.



Geographic patterns of mtDNA diversity in Europe.

The distribution of the zones of highest mitochondrial variation (genetic boundaries) confirmed that the Saami are sharply differentiated from an otherwise rather homogeneous set of European samples, and an area of significant clinal variation was identified around the Mediterranean Sea (and not in the north), even though the differences between northern and southern populations were insignificant.

Genetic diversity in the Iberian Peninsula determined from mitochondrial sequence analysis

The timing of divergence of populations within Iberia points to a shared ancestry of all populations in the Upper Palaeolithic, and lineage diversity comparisons with European and North African populations shows the Iberian Peninsula to be more similar to other European populations, although a small number of Iberians lineages can be traced to North Africa.

The emerging tree of West Eurasian mtDNAs: a synthesis of control-region sequences and RFLPs.

It is shown that the main indigenous North African cluster is a sister group to the most ancient cluster of European mtDNAs, from which it diverged approximately 50,000 years ago.

Tracing European founder lineages in the Near Eastern mtDNA pool.

Estimating Scandinavian and Gaelic ancestry in the male settlers of Iceland.

Results based on a study of Y-chromosome diallelic and microsatellite variation in 181 Icelanders, 233 Scandinavians, and 283 Gaels from Ireland and Scotland indicate closer matrilineal links with populations of the British Isles, which supports the model, put forward by some historians, that the majority of females in the Icelandic founding population had Gaelic ancestry.

Sequence diversity of the control region of mitochondrial DNA in Tuscany and its implications for the peopling of Europe.

The control region of mitochondrial DNA has been widely studied in various human populations. This paper reports sequence data for hypervariable segments 1 and 2 of the control region from a

High mitochondrial sequence diversity in linguistic isolates of the Alps.

Analysis of molecular variance shows significant differentiation within samples, among them, and among linguistic groups, and in the evolutionary trees where the four alpine groups are compared with other European populations, Mocheni and especially Ladins appear as clear outliers.

Genes and languages in Europe: an analysis of mitochondrial lineages.

It is argued that this apparent contradiction is attributable to the fact that genetic lineages and gene frequencies reflect different time perspectives on population history, the latter being more in concordance with linguistic evolution.

Paleolithic and neolithic lineages in the European mitochondrial gene pool.

It follows that the major extant lineages throughout Europe predate the Neolithic expansion and that the spread of agriculture was a substantially indigenous development accompanied by only a relatively minor component of contemporary Middle Eastern agriculturalists.

Geographic variation in human mitochondrial DNA control region sequence: the population history of Turkey and its relationship to the European populations.

Although there is a very low level of genetic divergence among Caucasoid populations as shown by mtDNA control region sequences, a geographic pattern of genetic variation emerges, denoting a stepping-stone position of Turkey between the Middle East and Europe, which is in agreement with the hypothesis of a replacement of Neanderthals by modern humans.
