Haplogroup I
"Haplogroup I, sometimes
referred to as the "Viking" haplotype, found in Scandanavia
and parts of Ireland, Scotland, and England, where it's thought
to denote descent from the Viking invaders of England, Scotland
and Ireland.
The ancestors of Haplogroup I
(defined by the M170 genetic marker) arrived from the Middle
East 20,000 to 25,000 years ago and are associated with the Gravettian
culture. Gravettian is the second subdivision of the Upper Paleolithic
technological phase in western Europe (from 27,000 to 21,000
years ago). Haplogroup I is most frequent in central Eastern
Europe and also occurs in Basques and Sardinians.
Gravettian culture A phase (c.28,000-23,000
ya) of the European Upper Paleolithic that is characterized by
a stone-tool industry with small pointed blades used for big-game
hunting (bison, horse, reindeer and mammoth). It is divided into
two regional groups: the western Gravettian, mostly known from
cave sites in France, and the eastern Gravettian, with open sites
of specialized mammoth hunters on the plains of central Europe
and Russia. Some early examples of cave art and the famous 'Venus'
figurines were made by Gravettian artists."
