This article deals with the European people as an ethnic group or ethnic groups. For information about residents or nationals of Europe, see Demography of Europe. For information on other uses please see disambiguation page: European

The European people may refer to the members of a collection of ethnic groups inhabiting the continent of Europe and their descendants.

Identity and culture

Culture / Ethnic areas of Europe. (Legend here)
Main article: European culture

A number of nations outside of Europe were originally established as colonies of European countries. Many of those nations retain a dominant "European culture" - that is a population whose ancestry, language and culture is largely derived from their European predecessors.[citation needed]

European is particularly common as an ethnic descriptor for those populations.[citation needed] While generally established by particular European countries, the immigration policy of these colonies has often been very open and inclusive towards other European nations, and thus a "European" identity has been preferred by government and social institutions[citation needed] over narrower categories such as English, British or German.

Physical appearance and genetics

Light skin

Further information: Human skin color and SLC24A5

Europeans have lighter skin (as measured by population average skin reflectance read by spectrophotometer) than other ethnic groups.[1] While all mean values of skin reflectance of non-European populations are lower than Europeans, some European and non-European populations overlap in lightness of skin,[2]

Humans have pigment cells, which contain pigment granules called melanosomes. In people of European descent, the melanosomes are relatively fewer and smaller than other human populations.[3]

Origins of light skin

According to a 2006 study, light pigmentation in Europeans is at least partially due to the effects of positive directional and/or sexual selection.[4] Europeans may have had an accumulation of lighter skin causing alleles, either by genetic drift, natural selection, sexual selection or a combination of these effects. Since their effects are additive it is possible light skin could arise over several generations without any new mutations taking place[5][6].

A historian suggested that Europeans may have retained their dark skin until as early as 13,000 years ago. This is based on Magdelanian cave art in which the painters depict hunters as darker than the animals hunted.[7]. Other scientists speculated that white skin mutation arose between 20,000 and 50,000 years ago. [8]

Hair and eye colors

Main articles: Hair color and eye color

A greater population diversity in hair and eye colors occurs in groups which are socially designated as white. Eye color experts Sturm and Frudakis note, "The common occurrence of lighter iris colours is found almost exclusively in Europeans and individuals of European admixture."[9]

Anthropologist Peter Frost geographically locates the variation as follows, "This diversity reaches a maximum in an area centered on the East Baltic and covering northern and eastern Europe." He speculates that this diversity may be because "sexual selection was much stronger among ancestral Europeans than in other human populations." [10] [11]

Blonde

Main article: Blonde

Lighter hair colors occur naturally in humans of all ethnicities as rare mutations, but at such low rates that it is hardly noticeable in most populations, or is only found in children.[12] In certain European populations, the occurrence of blond hair is more frequent, and often remains throughout adulthood. Based on recent genetic information, it is probable that humans with blond hair became distinctly numerous in Europe during the last Ice Age. Before then, Europeans had dark brown hair and dark eyes.[12]

Red Hair

Main article: Red hair

Red hair (also referred to as auburn, ginger, or titian) is a hair color that varies from a deep red through to bright copper. It is characterized by high levels of the reddish pigment pheomelanin and relatively low levels of the dark pigment eumelanin.[13]

Genetics

See also: Genetic history of Europe and Race and genetics

Haplogroups are branches on the tree of early human migrations and genetic evolution. Haplogroups are defined by genetic mutations or "markers" found in Y chromosome and mtDNA testing.[14] The examination of population differences within Europe using mitochondrial or Y chromosome haplogroups has been particularly useful in tracing part of the routes of migration and populating of Europe, but these haplogroups do not provide strong inferences on population genetic structure. [15]

According to University of Oulu Library (Finland):

Classical polymorphic markers (i.e. blood groups, protein electromorphs and HLA antigenes) have suggested that Europe is a genetically homogeneous continent with a few outliers such as the Saami, Sardinians, Icelanders and Basques (Cavalli-Sforza et al. 1993, Piazza 1993). The analysis of mtDNA sequences has also shown a high degree of homogeneity among European populations, and the genetic distances have been found to be much smaller than between populations on other continents. (Comas et al. 1997).

The mtDNA haplogroups of Europeans are surveyed by using a combination of data from RFLP analysis of the coding region and sequencing of the hypervariable segment I. About 99% of European mtDNAs fall into one of ten haplogroups: H, I, J, K, M, T, U, V, W or X (Torroni et al. 1996a). Each of these is defined by certain relatively ancient and stable polymorphic sites located in the coding region (Torroni et al. 1996a).......Haplogroup H, which is defined by the absence of a AluI site at bp 7025, is the most prevalent, comprising half of all Europeans (Torroni et al. 1996a, Richards et al. 1998)......Six of the European haplogroups (H, I, J, K, T and W) are essentially confined to European populations (Torroni et al. 1994, 1996a).[16][17]

mtDNA Haplogroup N1a while presently rare (.18%-.3%) occurred in as many as 25% of Neolithic Europeans and has subsequently been absorbed into the current populations [18][19].

Y chromosome markers

Distribution of European clusters identified by Bauchet. When two clusters are identified there is a north-southeast cline that may be due to demic diffusion during the European neolithic

There are three major haplogroups which account for most of Europe's present-day population.

  • Haplogroup R1b has it's highest frequencies on the Atlantic coast of Europe from Spain to Scotland.
  • Haplogroup I is common across central Europe and up into Scandinavia.
  • Haplogroup R1a is common in eastern, central and northern Europe.[20] [21] [22]

The most common haplogroup in Europe is R1b.[23] [24] Each haplogroup also have subclades. [25] R1a and R1b are subclades of Haplogroup R (Y-DNA) [26] Two main subgroups of Haplogroup I (Y-DNA) are I-M253/I-M307/I-P30/I-P40 which has highest frequency in Scandinavia, Iceland, and northwest Europe. The other is I-S31 which includes I-P37.2, which is the most common form in the Balkans and Sardinia, and I-S23/I-S30/I-S32/I-S33, which reaches its highest frequency along the northwest coast of continental Europe.[27]

A little later, around 4,500 years ago, Haplogroup N3 began moving across from west of the Ural mountains. Haplogroup N3 follows closely the spread of the Finno-Ugric languages.[20]

European population substructure

European population substructure, using Single nucleotide polymorphisms

In 2006, a study by 9 scientists made an analysis comparing different individuals from European ancestry groups. They concluded that "there is a consistent and reproducible distinction between “northern” and “southern” European population groups" [28]

While above scientists claimed that the people of British Isles cluster with Northern Europeans Stephen Oppenheimer stated: "By far the majority of male gene types in the British Isles derive from Iberia (Spain and Portugal)" [29]

Bryan Sykes, also stated that "The genetic evidence shows that a large proportion of Irish Celts, on both the male and female side, did arrive from Iberia at or the same time as farming reached the Isles" [30]

A recent genetic piece of research from 2007, claims: "The Spanish and Basque groups are the furthest away from other continental groups, which is consistent with the suggestions that the Iberian peninsula holds the most ancient European genetic ancestry".[citation needed] The same study also found "several significant axes of stratification, most prominently in a North-Southeastern trend but also along an East-West axis."[citation needed] They also confirmed English and Irish cluster with Northern Europeans such as Germans and Poles while some Basque and Italian individuals also clustered with Northern Europeans. Despite these stratifications, they also said: "there is low apparent diversity in Europe with the entire continent-wide samples only marginally more dispersed than single population samples elsewhere in the world." [31]

The predominance in every part of the Isles of the Atlantic chromosome (the most frequent in the Oisin clan), with its strong affinities to Iberia, along with other matches and the evidence from the maternal side convinces me that it is from this direction that we must look for the origin of Oisin and the great majority of our Y-chromosomes.
