"the Aryans R1b Western European Caucasoid haplotype and Eastern European South Asian R1a, R2 haplotype descended via the P haplotype from the Australoid K haplotype(with its daugher L haplotype and its ancestral C haplotype are also found in South Asia) or in layman's term, both the Aryans and the Dravidians shared the same ancestry in South Asia with the former who went northward then going to Central Asia and to the Middle East, then finally going to Europe. R splitted from K via P haplotype. Mongoloid O haplogroup also came from the K haplotype. C, D, K haplogroups travelled southward into SEA then northwards with K splitting to the various O haplogroups of East Asians and SEAsians. N, P, Q, S, and T all splitted from K. P haplotype the immediate ancestry of R haplogroup as accdg to wiki splitted from K during 20,000 to 40,000 yrs ago from Central Asia and siberia which is quite impossible knowing that the last glacial maximum which started 70,000 yrs ago and ending 10,000yrs ago was all covered with ice or if not in a very inhospitable condition. I wager tropical South Asia as the place of the splitting of R from P just like L splitted from K in South Asia also just about the same time."

"The paternal Y chromosome haplotype findings of Chu et al and Su et al concluded that East Asian Mongoloids came from Southeast Asia. The K* haplotype from SEA is probably the source of the Mongoloid Haplogroup O as well as Haplogroup N while it is virtually absent in Central Asia as well as the Near East.
In the newer Karafet studies, K* as well as NO* is found in the Philippine isles among Aetas, Surigaonons and Butanons. Those patrilines being ancestral to majority of Eurasians; Asians and Europeans.
The northern route or via Central Asia as Orthodox academicians preferred lack those K* and NO* markers and thus proving the southern route in the migrations of humans from Africa to South Asia then to Southeast Asia. Then K splitted to NO then splitted to O1, O2, O3 as they migrated up north. The Southern Route was verified by both Chu et al and Su et al and reflected on newer studies as well."

The highly structured distribution of Y-chromosome haplogroups suggests that current patterns of variation may be informative of past population processes. However, limited phylogenetic resolution, particularly of subclades within haplogroup K, has obscured the relationships of lineages that are common across Eurasia. Here we genotype 13 new highly informative single-nucleotide polymorphisms in a worldwide sample of 4413 males that carry the derived allele at M526, and reconstruct an NRY haplogroup tree with significantly higher resolution for the major clade within haplogroup K, K-M526. Although K-M526 was previously characterized by a single polytomy of eight major branches, the phylogenetic structure of haplogroup K-M526 is now resolved into four major subclades (K2a–d). The largest of these subclades, K2b, is divided into two clusters: K2b1 and K2b2. K2b1 combines the previously known haplogroups M, S, K-P60 and K-P79, whereas K2b2 comprises haplogroups P and its subhaplogroups Q and R. Interestingly, the monophyletic group formed by haplogroups R and Q, which make up the majority of paternal lineages in Europe, Central Asia and the Americas, represents the only subclade with K2b that is not geographically restricted to Southeast Asia and Oceania. Estimates of the interval times for the branching events between M9 and P295 point to an initial rapid diversification process of K-M526 that likely occurred in Southeast Asia, with subsequent westward expansions of the ancestors of haplogroups R and Q.
"This is a bad blow to Eurocentrists and to those who adhere to the northern Central Asian origin hypothesis.
K2c-P261 is found in Bali, and K2d-P402 is found in Java. K2b2*-P295 is found among the Aeta people of the Philippines, in Timor, in Sumba, and in Sulawesi. Most of the K2 branches are found in insular Southeast Asia."
