• Source: Haplogroup K-M9

Haplogroup K or K-M9 is a genetic lineage within human Y-chromosome DNA haplogroup. A sublineage of haplogroup IJK, K-M9, and its descendant clades represent a geographically widespread and diverse haplogroup. The lineages have long been found among males on every continent except Antarctica.
The direct descendants of Haplogroup K1 (L298 = P326, also known as LT) and K-M9 are Haplogroup K2 (formerly KxLT; K-M526).




Origins and distribution


Y-DNA haplogroup K-M9 is an old lineage that arose approximately 47,000-50,000 years ago. According to geneticist Spencer Wells, haplogroup K or the Eurasian clan, originated in the Middle East (perhaps Iran) or Central Asia.
Basal K* is exceptionally rare and under-researched; while it has been reported at very low frequencies on many continents it is not always clear if the examples concerned have been screened for subclades. Confirmed examples of K-M9* now appear to be most common amongst some populations in Island South East Asia and Melanesia.
Primary descendants of haplogroup LT are L (M20), also known as K1a, and T (M184), also known as K1b.
The descendants of haplogroup K2 include:

K2a (detected in paleolithic specimens Oase1 and Ust'-Ishim), the subclades of which include the major haplogroups N and O, and;
K2b – the ancestor of haplogroups M, P, Q, R, S.
