Haplogroup O, also known as O-M175, is a human Y-chromosome DNA haplogroup. It is primarily found among populations in Southeast Asia and East Asia. It also is found in various percentages of populations of the Russian Far East, South Asia, Central Asia, Caucasus, Crimea, Ukraine, Iran, Oceania, Madagascar and the Comoros.
The O-M175 Story. O-M175 's paternal line was formed when it branched off from the ancestor NO-M214 and the rest of mankind around 36,000 BCE. The man who is the most recent common ancestor of this line is estimated to have been born around 29,000 BCE.
