context_page_description: 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 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.
context_section_description: Haplogroup I is found at moderate to low frequencies in East Africa, Europe, West Asia and South Asia (Fernandes 2012). 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 (Olivieri 2013).
