R1B Haplogroup



Wikipedia:Haplogroup R1b (Y-DNA) provides current views of the R1b Haplogroup. The following discussion provides a brief overview.


Current views of the R1b haplogroup is that it originated about 18,500 years ago in western asia, perhaps in Anatolia[1] The oldest subclades of this group are found in the From there it is thought to have dispersed to the northwest into Europe at about the end of the last ice age, as well as east into Asia, and southwest into northern Africa. The dispersion of the R1b group is often associated with the spread of farming into Europe. Its modern european distribution shows a peak in northern Ireland, diminishing southeastward. This is believed to correspond to large scale "wave" migration of R1b peoples into Europe, with the bulk of the population moving with the wave, and remnants remaining in areas to the east of the wave. Scot-Irish immigration to America in the 18th and 19th centuries resulted in a substantial presence of R1b in this area today, and can perhaps be seen as a continuation of the original wave migration.
