Haplogroup I is a human mitochondrial DNA (mtDNA) haplogroup. It is believed to have originated about 21,000 years ago, during the Last Glacial Maximum (LGM) period in West Asia (; ;). The haplogroup is unusual in that it is now widely distributed geographically, but is common in only a few small areas of East Africa, West Asia and Europe. It is especially common among the El Molo and Rendille peoples of Kenya, various regions of Iran, the Lemko people of Slovakia, Poland and Ukraine, the island of Krk in Croatia, the department of Finistère in France and some parts of Scotland and Ireland.

Origin

Haplogroup I is a descendant (subclade) of haplogroup N1a1b and sibling of haplogroup N1a1b1 . It is believed to have arisen somewhere in West Asia between 17,263 and 24,451 years before present (BP), with coalescence age of 20.1 thousand years ago . It has been suggested that its origin may be in Iran or more generally the Near East . It has diverged to at least seven distinct clades i.e. branches I1–I7, dated between 16–6.8 thousand years . The hypothesis about its Near Eastern origin is based on the fact that all haplogroup I clades, especially those from Late Glacial period (I1, I4, I5, and I6), include mitogenomes from the Near East . The age estimates and dispersal of some subclades (I1, I2’3, I5) are similar to those of major subclades of the mtDNA haplogroups J and T, indicating possible dispersal of the I haplogroup into Europe during the Late Glacial period (c. 18–12 kya) and postglacial period (c. 10–11 kya), several millennia before the European Neolithic period. Some subclades (I1a1, I2, I1c1, I3) show signs of the Neolithic diffusion of agriculture and pastoralism within Europe .

A similar view puts more emphasis on the Persian Gulf region of the Near East .

Distribution

Haplogroup I is found at moderate to low frequencies in East Africa, Europe, West Asia and South Asia . In addition to the confirmed seven clades, the rare basal/paraphyletic clade I* has been observed in three individuals; two from Somalia and one from Iran .

Africa

The highest frequencies of mitochondrial haplogroup I observed so far appear in the Cushitic-speaking El Molo (23%) and Rendille (>17%) in northern Kenya . The clade is also found at comparable frequencies among the Soqotri (~22%).[1]

Asia

Haplogroup I is present across West Asia and Central Asia, and is also found at trace frequencies in South Asia. Its highest frequency area is perhaps in northern Iran (9.7%). Terreros 2011 notes that it also has high diversity there and reiterates past studies that have suggested that this may be its place of origin.

Europe

Eastern Europe

In Eastern Europe, the frequency of haplogroup I is generally lower than in Western Europe (1 to 3 percent), but its frequency is more consistent between populations with fewer places of extreme highs or lows. There are two notable exceptions. Nikitin 2009 found that Lemkos (a sub- or co-ethnic group of Rusyns) in the Carpathian mountains have the "highest frequency of haplogroup I (11.3%) in Europe, identical to that of the population of Krk Island (Croatia) in the Adriatic Sea".[2] [3]

Western Europe

In Western Europe, haplogroup I is most common in Northwestern Europe (Norway, the Isle of Skye, and the British Isles). The frequency in these areas is between 2 and 5 percent. Its highest frequency in Brittany, France where it is over 9 percent of the population in Finistère. It is uncommon and sometimes absent in other parts of Western Europe (Iberia, South-West France, and parts of Italy).

Historic and prehistoric samples

Haplogroup I has until recently been absent from ancient European samples found in Paleolithic and Mesolithic grave sites. In 2017, in a site on Italian island of Sardinia was found a sample with the subclade I3 dated to 9124–7851 BC, while in the Near East, in Levant was found a sample with yet-not-defined subclade dated 8850–8750 BC, while in Iran was found a younger sample with subclade I1c dated to 3972–3800 BC . In Neolithic Spain (c. 6090–5960 BC in Paternanbidea, Navarre) was found a sample with yet-not-defined subclade . Haplogroup I displays a strong connection with the Indo-European migrations; especially its I1, I1a1 and I3a subclades, which have been found in Poltavka and Srubnaya cultures in Russia (Mathieson 2015), among ancient Scythians (Der Sarkissian 2011), and in Corded Ware and Unetice Culture burials in Saxony .I3a has also been found in the Unetice Culture in Lubingine, Germany 2,200 B.C. to 1,800 B.C. courtesy article on Unetice Culture Wikipedia of 2 Skeletons that were DNA tested. Haplogroup I (with undetermined subclades) has also been noted at significant frequencies in more recent historic grave sites (and).

In 2013, Nature announced the publication of the first genetic study utilizing next-generation sequencing to ascertain the ancestral lineage of an Ancient Egyptian individual. The research was led by Carsten Pusch of the University of Tübingen in Germany and Rabab Khairat, who released their findings in the Journal of Applied Genetics. DNA was extracted from the heads of five Egyptian mummies that were housed at the institution. All the specimens were dated to between 806 BC and 124 AD, a time frame corresponding with the Late Dynastic and Ptolemaic periods. The researchers observed that one of the mummified individuals likely belonged to the I2 subclade.[4] Haplogroup I has also been found among ancient Egyptian mummies excavated at the Abusir el-Meleq archaeological site in Middle Egypt, which date from the Pre-Ptolemaic/late New Kingdom, Ptolemaic, and Roman periods.[5]

Haplogroup I5 has also been observed among specimens at the mainland cemetery in Kulubnarti, Sudan, which date from the Early Christian period (AD 550–800).[6]

The frequency of haplogroup I may have undergone a reduction in Europe following the Middle Ages. An overall frequency of 13% was found in ancient Danish samples from the Iron Age to the Medieval Age (including Vikings) from Denmark and Scandinavia compared to only 2.5% in modern samples. As haplogroup I is not observed in any ancient Italian, Spanish [contradicted by the recent research as have been found in pre-Neolithic Italy as well Neolithic Spain], British, central European populations, early central European farmers and Neolithic samples, according to the authors "Haplogroup I could, therefore, have been an ancient Southern Scandinavian type "diluted" by later immigration events" .

I2'3

I2'3
Origin-Date:11,308 ± 4,154 BP
Origin-Place:Insufficient Data
Ancestor:I
Mutations:T152C!, G207A

It is the common root clade for subclades I2 and I3. There's a sample from Tanzania with which I2'3 shares a variant at position 152 from the root node of haplogroup I, and this "node 152" could be upstream I2'3s clade . Both I2 and I3 might have formed during the Holocene period, and most of their subclades are from Europe, only few from the Near East . Examples of this ancestral branch have not been documented.
