      Your Origin
      The mitochondrial super-haplogroup U encompasses haplogroups U1-U7 and haplogroup K. Haplogroup K is found through Europe, and contains multiple closely related lineages indicating a recent population expansion. The origin of haplogroup K dates to approximately 16,000 years ago, and it has been suggested that individuals with this haplogroup took part in the pre-Neolithic expansion following the Last Glacial Maximum.

      Haplogroup K is believed to have originated in the mid-Upper Paleolithic, between about 30,000 and 22,000 years ago. It is the most common subclade of haplogroup U8b.[3] with an estimated age of c. 12,000 years BP.[4]

      Projected spatial frequency distribution for haplogroup K.
      Haplogroup K appears in West Eurasia, North Africa, the Horn of Africa and South Asia, and in populations with such an ancestry.

      Haplogroup K is found in approximately 10% of native Europeans.[5][6]

      Overall the mtDNA haplogroup K is found in about 6% of the population of Europe and the Near East, but it is more common in certain of these populations. Approximately 16% of the Druze of Syria, Lebanon, Israel, and Jordan, belong to haplogroup K.[7] It is also found among 8% of Palestinians.[8] Additionally, K reaches a level of 17% in Kurdistan.[9]

      Approximately 32% of people with Ashkenazi Jewish ancestry are in haplogroup K. This high percentage points to a genetic bottleneck occurring some 100 generations ago.[7] Ashkenazi mtDNA K clusters into three subclades seldom found in non-Jews: K1a1b1a, K1a9, and K2a2a. Thus it is possible to detect three individual female ancestors, who were thought to be from a Hebrew/Levantine mtDNA pool, whose descendants lived in Europe.[10] Recent studies suggest these clades originate from Western Europe.[11]

      The average of European K frequency is 5.6%. K appears to be highest in the Morbihan (17.5%) and Périgord-Limousin (15.3%) regions of France, and in Norway and Bulgaria (13.3%).[12] The level is 12.5% in Belgium, 11% in Georgia and 10% in Austria and Great Britain.[9]

      Haplogroup K is also found among Gurage (10%),[8] Syrians (9.1%),[8] Afar (6.3%),[8] Zenata Berbers (4.11%),[13] Reguibate Sahrawi (3.70%),[13] Oromo (3.3%),[8] Iraqis (2.4%),[8] Saudis (0%-10.5%),[8] Yemenis (0%-9.8%),[8] and Algerians (0%-4.3%).[13]

      A study involving Caucasian patients showed that individuals classified as haplogroup J or K demonstrated a significant decrease in risk of Parkinson's disease versus individuals carrying the most common haplogroup, H.[24]

      Origin and Migrations of Haplogroup K
      Haplogroup K is actually a branch of haplogroup U, and traces back to a woman who lived nearly 27,000 years ago in the Middle East. It continues to have a strong presence in the region today, reaching levels of 20% among Druze Muslims and about 10% among Kurds, Palestinians and Yemenites. It is also found among the Gurage of Ethiopia, who are thought to be descended from Arabian invaders.

      K spread from the Middle East into Europe about 15,000 to 12,000 years ago, as the Ice Age was ending and temperate forests spread over the previously frigid continent. It is still found at low levels in most European populations, where many branches of the haplogroup match identical ones from the Middle East. That close similarity suggests that more recent migrations also may have carried haplogroup K from the Middle East to Europe, perhaps with the spread of agriculture about 8,000 years ago.

      Haplogroup K also extends into Central Asia as far as the Altay Mountains, a range that runs along the western edge of Mongolia's Gobi Desert. It may have reached there with relatively ancient migrants from the Middle East, and then been spread to other parts of Asia during the medieval expansion of the Turkic peoples to the Urals and modern-day Turkey.

      14,500 Years Ago
      Your maternal haplogroup, K2b, traces back to a woman who lived approximately 14,500 years ago.

      That's nearly 580 generations ago! What happened between then and now? As researchers and citizen scientists discover more about your haplogroup, new details may be added to the story of your maternal line.
