- Haplogroup K2b (P331), also known as MPS is a human y-chromosome haplogroup that is thought to be less than 3,000 years younger than K, and less than 10,000 years younger than F, meaning it probably is around 50,000 years old, according to the age estimates of Tatiana Karafet et al. 2014. Basal K2b* has not been identified in living males. It has been found only in the remains of an individual known as Tianyuan man, who was alive some time between 42,000 and 39,000 years BP, during the upper paleolithic era, near the future site of Beijing, China. (For a time, the basal clade was also attributed, erroneously, to another individual, known as RISE94, who lived 3,000 years BP, in what is now Sweden. However, RISE94 is now known to belong to R1a.) K2b1 (P397/P399) known previously as Haplogroup MS, and Haplogroup P (P-P295), also known as K2b2 are the only primary clades of K2b. The population geneticist and other researchers (2014) point out that K2b1, its subclades and P* are virtually restricted geographically to South East Asia and Oceania. Whereas, in a striking contrast, P1 (P-M45) and its primary subclades Q and R now make up "the most frequent haplogroup in Europe, the Americas, and Central Asia and South Asia". According to Karafet et al., the estimated dates for the branching of K, K2, K2b and P point to a "rapid diversification" within K2 "that likely occurred in Southeast Asia", with subsequent "westward expansions" of P*, P1, Q and R. According to a study by geneticist Spencer Wells, haplogroup K, from which haplogroup P descend, originated in the Middle East or Central Asia. It is likely that haplogroup P diverged somewhere in South-Central Asia into P1, which expanded into Siberia and Northern Eurasia, and into P2, which expanded into Oceania and Southeast Asia. (en)
