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 can be found in most present-day European populations, with peaks in some Northern European and South East European countries.
This haplogroup reaches its maximum frequency in the Western Balkans (with the highest concentration in present-day Herzegovina). It may be associated with unusually tall males, since those in the Dinaric Alps have been reported to be the tallest in the world, with an average male height of the range 180 cm (5 ft 11 in)-182 cm (6 ft 0 in) in the cantons of Bosnia, 184 cm (6 ft 0 in) in Sarajevo, 182 cm (6 ft 0 in)-186 cm (6 ft 1 in) in the cantons of Herzegovina.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.
