My Y chromosome results identify me as a member of haplogroup R1b1b2a1a* (ISOGG - Conversion Table [MS Word]). The YDNA Haplogroup R1b-U106/S21+ Research Group has adopted the designation R1b-U106/S21. This recognizes R1b as the most stable upstream haplogroup designation and U106/S21= rs16981293 as the confirmed lowest downstream YSNP. This change is simpler naming convention in light of the new YDNA tree structure annouced in the April on-line issue of 2008 Genome Research, which designates U106/S21 as haplogroup R1b1b2g. This is a lineage defined by a genetic marker called M269. This haplogroup is the final destination of a genetic journey that began some 60,000 years ago with an ancient Y chromosome marker called M168.

As the debate continues, the age and origins ofor R1b1b2a1a* changes all the time. Whereas some claim that the origins of U106/S21 are to be found in Eastern Europe, others continue to stick to the theory that R1b1c spend the LGM in Iberia.

1. The first mentioned opinion is based on Hammer's theory that R1b is only 18,000 years old and entered Europe from the east, and that it thus seems impossible that any R1b1c's were in an Iberian refugium during LGM. Furthermore, it is argued that because R1b-U106 is S116- means that it arose from an earlier R1b-M269 line than all the other R1b-M269 subclades (R1b1c7, R1b1c10, etc.). Given that R1b-M269 entered Europe from the East, the older the subclade the more likely it was to have arisen farther to the east in Europe than the Atlantic coast.

2. Those supporting the second opinion argue that any origin theory needs to take into account the influence of the last Ice Age on human migration across Europe. The available evidence shows that M269 was well entrenched in Western Europe by the end of the last glacial maximum and almost certainly taking refuge in the Iberian and Italian refuges. They point out that this is the only way to explain why M269 is so predominant in the western part Of Europe and declines rapidly as you move to the eastern part.
The available data for U106/S21 shows that it most likely originated after the LGM, i.e. when M269 was already entrenched in western Europe. Unless the M269 forebears of U106/S21 migrated back east from their refuges, a western European origin makes more sense. Whether this should be called "Frisian", "Scandinavian", "Baltic". "North Sea" or "Germanic" remains to be decided.

R1b1c9 or S21 is thought to be around ninety generations old. It includes 25% of western European males found in Norway, Italy, Germany, Scotland, England, Ireland, Wales, which includes the "Frisian" group (40% of men in northern Holland are S21+). Linguistically, "Frisia" covered the coastal area from southern Denmark in the east to Flanders in the west prior to the Middle Ages. "Frisia" should not be confused with present-day "Friesland", which is a northern province of The Netherlands. Between 50% and 100% of "frisian" genes exist in the middle of England. This may indicate an Anglo Saxon invasion, though there is no real "proof" of this.

I belong to this group and my earliest known ancestor came from Darmstadt in the southern part of Hesse, which is situated in western-central Germany. However, since the early 1700's all members of the family have lived in The Netherlands, although a few have emigrated to Canada and New Zealand during the later part of the previous century and even more recently.

What follows are some theories about the R1b lineage.

The very widely dispersed M168 marker can be traced to a single individual — "Eurasian Adam." This African man, who lived some 31,000 to 79,000 years ago, is the common ancestor of every non-African person living today. His descendants migrated out of Africa and became the only lineage to survive away from humanity's home continent.

Population growth during the Upper Paleolithic era may have spurred the M168 lineage to seek new hunting grounds for the plains animals crucial to their survival. A period of moist and favorable climate had expanded the ranges of such animals at this time, so these nomadic peoples may have simply followed their food source.

Improved tools and rudimentary art appeared during this same epoch, suggesting significant mental and behavioral changes. These shifts may have been spurred by a genetic mutation that gave "Eurasian Adam's" descendants a cognitive advantage over  other contemporary, but now extinct, human lineages.

Some 90 to 95 percent of all non-Africans are descendants of the second great human migration out of Africa, which is defined by the marker M89.  

M89 first appeared 45,000 years ago in Northern Africa or the Middle East. It arose on the original lineage (M168) of "Eurasian Adam," and defines a large inland migration of hunters who followed expanding grasslands and plentiful game to the Middle East.

Many people of this lineage remained in the Middle East, but others continued their movement and followed the grasslands through Iran to the vast steppes of Central Asia. Herds of buffalo, antelope, woolly mammoths, and other game probably enticed them to explore new grasslands.

With much of Earth's water frozen in massive ice sheets, the era's vast steppes stretched from eastern France to Korea. The grassland hunters of the M89 lineage traveled both east and west along this steppe "superhighway" and eventually peopled much of the continent.

A group of M89 descendants moved north from the Middle East to "Anatolia and the Balkans, trading familiar grasslands for forests and high country. Though their numbers were likely small, genetic traces of their journey are still found today.

Some 40,000 years ago a man in Iran or southern Central Asia was born with a unique genetic marker known as M9, which marked a new lineage diverging from the M89 group. His descendants spent the next 30,000 years populating much of the planet.

Most residents of the Northern Hemisphere trace their roots to this unique individual, and carry his defining marker. Nearly all North ; Americans and East Asians have the MP marker, as do most Europeans and many Indians. The haplogroup defined by M9, K, is known as the Eurasian Clan.This large lineage dispersed gradually. Seasoned hunters followed the herds ever eastward, along a vast belt of Eurasian steppe, until the massive mountain ranges of south central Asia blocked their path.  

The Hindu Kush, Tian Shan, and Himalaya, even more formidable during the era's ice age, divided eastward migrations. These migrations through the "Pamir Knot" region would subsequently become defined by additional genetic markers. The marker M45 first appeared about 35,000 to 40,000 years ago in a man who became the common ancestor of most Europeans and nearly all Native Americans. This unique individual was part of the M9 lineage, which was moving to the north of the mountainous Hindu Kush and onto the game‑rich steppes of Kazakhstan, Uzbekistan, and southern Siberia.

The M45 lineage survived on these northern steppes even in the frigid ice Age climate. While big game was plentiful, these resourceful hunters had to adapt their behavior to an increasingly hostile environment. They erected animal skin shelters and sewed weathertight clothing. They also refined the flint heads on their weapons to compensate for the scarcity of obsidian and other materials.

The intelligence that allowed this lineage to adapt and thrive in harsh conditions was critical to human survival in a region where no other hominids are known to have survived.

Members of haplogroup R are descendents of Europe's first largescale human settlers. The lineage is defined by Y chromosome marker M173, which shows a westward journey of M45-carrying Central Asian steppe hunters.

The descendents of M173 arrived in Europe around 35,000 years ago and immediately began to make their own dramatic mark on the continent. Famous cave paintings, like those of Lascaux and Chauvet, signal the sudden arrival of humans with artistic skill. There are no artistic precedents or precursors to their appearance.

Soon after this lineage's arrival in Europe, the era of the Neandertals came to a close. Genetic evidence proves that these hominids were not human ancestors but an evolutionary dead end. Smarter, more resourceful human descendents of M173 likely outcompeted Neandertals for scarce ice Age resources and thus heralded their demise.

The long journey of this lineage was further shaped by the preponderance of ice at this time. Humans were forced to southern refuges in Spain, Italy, and the Balkans. Years later, as the ice retreated, they moved north out of these isolated refuges and left an enduring, concentrated trail of the M173 marker in their wake.

Today, for example, the marker's frequency remains very high in northern France and the British Isles — where itwas carried by M173 descendents who had weathered the Ice Age in Spain.

Members of haplogroup R1b, defined by M343 are the direct descendents of Europe's firstmodern humans — known as the Cro-Magnon people.

Cro‑Magnons arrived in Europe some 35,000 years ago, during a time when Neandertals still lived in the region. M343‑carrying peoples made woven clothing and constructed huts to withstand the frigid climes of the Upper Paleolithic era. They used relatively advanced tools of stone, bone, and ivory. Jewelry, carvings, and intricate, colorful cave paintings bear witness to the Cro Magnons' surprisingly advanced culture during the last glacial age.

When the ice retreated genetically homogenous groups recolonized the north, where they are still found in high frequencies. Some 70 percent of men in southern England are R1b. In parts of Spain and Ireland that number exceeds 90 percent.

There are many sublineages within R1b that are yet to be defined. The Genographic Project hopes to bring future clarity to the disparate parts of this distinctive European lineage.

Notice from David Weston, Group Administrator R1b-U106/S21+ Research Group - July 20, 2008

Hello,

I have deliberately limited my comments and analysis on U106 research to date due to the still relatively small number of confirmed U106 haplotypes. I am happy now though to make one statistically significant observation on the data that I believe has not yet been made. There is a geographic split in U106 between north eastern and north western Europe, with DYS390 = 23 dominant in the west and DYS390 = 24 very dominant in the east.

The following table breaks down the current numbers and frequencies for DYS390 = 23 and 24 by region within the R1b-U106/S21+ Research Group and includes data from the U198/S29 and Null 439 Projects: The CI or confidence interval is the statistical uncertainty due to sampling error to a 95% confidence level and includes a correction for small sample sizes. This is the +/- percent error 19 times in 20. For region definitions and counts by country see the R1b-U106/S21+ Research Group website Results page. The following plot shows the available group participant European MDA origins and differentiating by DYS390 value.

In general, ~53% of U106 is DYS390 = 23 and ~36% is DYS390 = 24. The DYS390 modal (most commonly occuring) value for non-U106 R1b-M269 haplotypes is 24. In the S116+ Project ~12% of DYS390 = 23 and ~73% is DYS390 = 24.

There is also a very strong split within the U106 subclades in DYS390. L1/S26 or Null 439 is ~90% DYS390 = 24, whereas U198/S29 is ~95% DYS390 = 23. The above data set does not include any eastern European L1.

I am not sure what to make of this and would appreciate any comments and opinions. I am considering one of two founder/migration scenarios, which at this point is largely speculation on my part for the sake of discussion:

1) The U106 founder split off from M269 (or some yet to be discovered intermediary SNP) with DYS390 = 24 in north eastern Europe (Baltics) and migrates west. The L1/S26 subclade then split off soon after and keeps the DYS390 = 24 value. Then DYS390 changes to 23 within U106* as the "clan" moved northwest and at some point U198/S29 splits off from U106* keeping the 23 value.

Or,

2) The U106 founder split off from M269 (or some yet to be discovered intermediary SNP) with DYS390 = 24 in south/central Scandinavia. The U106 "clan" then migrates southeast into the Baltics and southwest into Frisia and northern Germany, where it becomes the dominant haplogroup. The L1/S26 subclade splits off U106 in the northwest and keeps the DYS390 = 24 value. Then DYS390 changes to 23 within U106* in the northwest and at some point U198/S29 splits off from U106* keeping the 23 value.

I am partial to option 2 as the most likely scenario explaining the founding and distribution of U106. U106 is appearing as far north as the northwest coasts of Norway and Finland. I do not believe that U106 was founded in north western Europe (Benelux/northern Germany). A founding in north western Europe does not adequately explain to me the U106 that is occuring in Scandinavia and eastern Europe. My understanding of the Migration Periods and Neolithic European agricultural expansion, the events likely having the greatest effect on the current distribution of U106 in continental Europe, is migration from generally East to West and North to South. My understanding of the Migration Periods <http://en.wikipedia.org/wiki/Migration_Period>
and Neolithic European agricultural expansion <http://en.wikipedia.org/wiki/Neolithic_Europe>, the events likely having the greatest effect on the current distribution of U106 in continental Europe, is migration from generally East to West and North to South. I am not aware of significant enough west to east migrations that would account for the numbers and distribution of U106 we are seeing in eastern Europe today. If I am missing something please let me know.

Note, I am deliberating avoiding mentioning of timings at this point due to the uncertainty and continued lack of broad agreement over founder ages. However, I do believe any age estimate must be able to explain the wide distribution of U106 across northern Europe we are seeing.
Cheers, David.

Further:
The age estimates of U106 to date range from around 3,000 yrs to 9,000 yrs old. The younger age estimates are probably more likely as the older estimates were based on short haplotypes of 6 to 12 markers and less knowledge of mutation rates than we have today. The younger estimates come extended haplotypes of over 50 markers and more reliable mutation rate estimates.

Regardless, U106 was almost certainly in place and spreading within its native community by the start of the European Bronze Age, circa 1800 BCE. If U106 originated in the Germanic tribes of southern Scandinavia, it makes sense then that the distribution of U106 would follow the movement of these tribes south, south-east and south-west.

Finland was part of the Kingdom of Sweden from about 1200-1800 A.D. and Finnish and Swedish are the official languages of Finland. The U106 we are seeing in Finland could well be attributed to settlement by Swedes in Finland during this period. Parts of the Baltics and Russia, such as the Kingdom of Kiev, were settled by the Varangians (Vikings, Norsemen, Swedes) from southern Scandinavia, the "Rus" , in the 9th and 10th centuries. Thus the U106 we are seeing there again could be traced back to southern Scandinavia. The settlement of north western Europe by northern Germanic tribes (Angles, Saxons, Jutes, etc.), who trace their roots to southern Scandinavia is well known.

There is no known migration out of central Europe or north western Europe into the regions where we are finding U106, particularly Scandinavia, in the numbers we are seeing that would account for its presence there. At this point the most likely origin of U106 seems to be southern Scandinavia. When more Europeans have there DNA tested, the genetic diversities and degree of relatedness between each of the region populations should become more focussed and may show more clearly the point of origin of U106.
