My migration pattern of Haplogroup I
My Y-DNA HAPLO group is I-M223 which is a subgroup of I-M170
- Parent haplogroup: I-M170. Age: 25,000
Region: Western Asia to Western Europe; very low frequency in the Middle East. Along with G one of the first haplogroups in Europe.
Available evidence suggests that I-M170 was preceded into areas in which it would later become dominant by haplogroups K2a (K-M2308) and C1 (Haplogroup C-F3393). K2a and C1 have been found in the oldest sequenced male remains from Western Eurasia (dating from circa 45,000 to 35,000 years BP), such as: Ust’-Ishim man (modern west Siberia) K2a*, Oase 1 (Romania) K2a*, Kostenki 14 (south west Russia) C1b, and Goyet Q116-1 (Belgium) C1a. The oldest I-M170 found is that of an individual known as Krems WA3 (lower Austria), dating from circa 33,000-24,000 BP. At the same site, two twin boys were also found, both were assigned to haplogroup I*.
Haplogroup IJ was in the Middle East and/or Europe about 40,000 years ago.The TMRCA (time to most recent common ancestor) for I-M170 was estimated to be 22,200 years ago, with a confidence interval between 15,300–30,000 years ago. This would make the founding event of I-M170 approximately contemporaneous with the Last Glacial Maximum (LGM), which lasted from 26,500 years ago until approximately 19,500 years ago. TMRCA is an estimate of the time of subclade divergence.
I-M223 is the shorthand form of the Y-DNA Haplogroup I branch and can also be shown as I2-M223. The M223 refers to the SNP at Hg38 location 19555421 on the Y-Chromosome with mutation G to A.
This mutation occurred in a man, approximately 17,400 years ago and M223 is one of 23 SNPs found derived (+) at the I-M223 node. We do not know which of the 23 SNPs mutated first and which was last. All men that are derived for M223 share a common ancestor that lived at least 13,200 to 10,800 years ago. It has now been confirmed by ancient DNA test that the first Homo sapiens to colonize Europe during the Aurignacian period (45,000 to 28,000 years ago), belonged to haplogroups CT, C1a, C1b, F and haplogroup I (to which my M223 belongs).
Haplogroup Y-M223 (formerly I2a2a) has been found in over 4% of the population only in Germany, the Netherlands, Belgium, Denmark, Scotland, and England (excluding Cornwall) – also the southern tips of Sweden and Norway in Northwest Europe; the provinces of Normandy, Maine, Anjou, and Perche in northwestern France; the province of Provence in southeastern France; the regions of Tuscany, Umbria, and Latium in Italy; Moldavia and the area around Russia’s Ryazan Oblast and Mordovia in Eastern Europe.
Haplogroup I-M223 variants:
- Note: On the 29th June 2018, the International Society of Genetic Genealogy (ISOGG) updated the Haplogroup I Tree to accommodate new branches and I-M223 has been given a new longhand classification of I2a1b1. Previous names were I2a2a, I2b1 and I1c, so please be careful as earlier reference material may refer to I-M223 or sub-clades under one of these previous longhand classifications. I-P222 is a sub-branch of I-M223 and is the parent branch of all sub-branches and clades in this Project. The I-P222 branch node has a further 55 SNPs. Sequencing ancient Y-DNA found at least two ancient male remains that were I-M223 but of a different sub-branch named I-FT355000. This is why I-M223 branch was split into the two sub-branches.
The I-M223 tree is incredibly old, approximately 17,400 years old.
There was a first man to be I-M223. He lived in Europe—probably. He lived 14,000 to 18,000 years ago—probably. We will never really know, because the only people we can test are his sons’ sons’ sons’ … sons’ sons who are alive today, including you.
His father was not I-M223. Neither were his brothers. They were I-M170. One of his father’s sperm had a Y-chromosome that had mutated, creating a slightly different order of base pairs. That sperm fertilized his mother’s egg at his conception and the I-M223 “family” was created in that moment.
The only reason this “type” (I-M223) shows up among the noise of history is because his male line survived. The first I-M223 had sons. If they had been named Rubble and kept his surname, they all would have been Rubbles. All of their sons were I-M223, and would have been Rubbles.
My paternal cousins (people you can trace to with only this male line) were probably among the first (re)settlers of Britain, Ireland, and Scandinavia as the ice sheets receded. The “surname” stayed with them. Sometimes it grew in population in a particular area when a man had a lot of sons; sometimes it died out in a particular area when all the men with the “surname” had no sons.
How much of this is random?
Well, areas populated predominantly with this lineage do seem to be associated with Germanic languages—not because the first I-M223 man spoke a Germanic language (he most definitely did not), but because by about 1000 BCE many proto-Germanic groups had large numbers of I-M223 men—like the areas in northern Sweden and the centre of Germany that are dark blue in the modern map. The regional concentrations may be due to particular “branches of the Rubble family” that became dominant patrilineal clans in various Germanic tribes.
It is, in one way, very much like a surname—just a name. BUT a name with a lot more history.
