Paternal Haplogroup

Life  Terror. Ecstasy. Fight. Denial. Flight. Failure. PAIN. Forgiveness. Reconciliation. Hope. Love. Peace – Death.

My Paternal Haplogroup is I, a Y-DNA Haplogroup.

300,000 years ago Y-Adam to about 43,000 years ago – I

The origin of haplogroup I resides in Asia Minor.

It is a haplogroup with a high diffusion in the countries of northern and southeastern Europe (Balkans, Nordic peoples, Sardinia, etc.). In fact, it is so common that it is present in one fifth of the European population. Making me pretty ordinary!

Well-known personalities such as Bill Clinton, Warren Buffet, Jimmy Carter, Novak Djokovic, Bill Gates, Chuck Norris and Stephen King are also part of this haplogroup.

Haplogroup I (M170) is a Y-chromosome DNA haplogroup. It is a subgroup of haplogroup IJ, which itself is a derivative of the haplogroup IJK. Subclades I1 and I2 can be found in most present-day European populations, with peaks in some Northern European and Southeastern European countries.

Haplogroup I appears to have arisen in Europe, so far being found in Palaeolithic sites throughout Europe (Fu 2016), but not outside it. It diverged from common ancestor IJ about 43,000 years B.P. (Karafet 2008). Early evidence for haplogroup J has been found in the Caucasus and Iran (Jones 2015, Fu 2016). In addition, living examples of the precursor Haplogroup IJ have been found only in Iran, among the Mazandarani and ethnic Persians from Fars. This may indicate that IJ originated in South West Asia.

Haplogroup I has been found in multiple individuals belonging to the Gravettian culture. The Gravettians expanded westwards from the far corner of Eastern Europe, likely Russia, to Central Europe. They are associated with a genetic cluster that is normally called the Věstonice cluster.

The five known cases of Haplogroup I from Upper Paleolithic European human remains make it one of the most frequent haplogroup from that period. In 2016, the 31,210–34,580-year-old remains of a hunter-gatherer from Paglicci Cave, Apulia, Italy were found to carry I-M170. 

So far, only Haplogroup F* and Haplogroup C1b have been documented, once each, on older remains in Europe. I2 subclade of I-M170 is the main haplogroup found on male remains in Mesolithic Europe, until circa 6,000 BCE, when mass migration into Europe of Anatolian farmers carrying Y-DNA G2a happened.

Due to the arrival of so-called Early European Farmers (EEFs), I-M170 is outnumbered by Haplogroup G among Neolithic European remains and by Haplogroup R in later remains. The earliest documentation of I1 is from Neolithic Hungary, although it must have separated from I2 at an earlier point in time. In one instance, haplogroup I was found far from Europe, among 2,000-year-old remains from Mongolia.

It would seem to be that separate waves of population movement impacted Southeastern Europe. The role of the Balkans as a long-standing corridor to Europe from Anatolia and/or the Caucasus is shown by the common phylogenetic origins of both haplogroups I and J in the parent haplogroup IJ (M429). This common ancestry suggests that the subclades of IJ entered the Balkans from Anatolia or the Caucasus, some time before the Last Glacial Maximum. I and J were subsequently distributed in Asia and Europe in a disjunctive phylogeographic pattern typical of “sibling” haplogroups. A natural geographical corridor like the Balkans is likely to have been used later by members of other subclades of IJ, as well as other haplogroups, including those associated with Early European Farmers.

The existence of Haplogroup IJK – the ancestor of both haplogroups IJ and K (M9) – and its evolutionary distance from other subclades of Haplogroup F (M89), supports the inference that haplogroups IJ and K both arose in Southwestern Asia. Living carriers of F and IJ have been reported from the Iranian Plateau
