I think every West Eurasian lineages in Central Asia was there already and Turks didn't bring any new ones. Just certain lineages lke R1b-M73 just expanded for whatever reason with Turks and increased in frequency for the same reason R1a expanded with Indo-Iranians and became so strong in places like Kyrgzstan/Afghanistan when without that ydna being selected for they would have a more even mix of Neolithic and Indo-European ydnas. I am curious if I or N ever existed in Central Asia though.<br /><br />R1b-M269 in iran is interesting too. When did it get there? I have heard everything from an origin there, to being Mesolithic, Neolithic or even being attibuted to Hurrian/Syrian/Assyrian/Armenian admixture. The R1b originated in Anatolia to me and moved east during the Neolithic theory makes most sense.newtoboardhttps://www.blogger.com/profile/13713811322016152404noreply@blogger.comtag:blogger.com,1999:blog-2845420051498655579.post-80777701544423397512012-06-26T18:34:32.769-07:002012-06-26T18:34:32.769-07:00newtoboard, this is the final warning regarding mu...newtoboard, this is the final warning regarding multi-posting. I will remove future consecutive messages without hesitation after you've made one per entry. This is a research blog and not a forum.<br /><br />I am contemplating the possibility that the R1b1a2-M269 in Central Asia may be attributed to BMAC farmers and *happened* to not reach the same prominence as farming communities further west. <br /><br />There is indeed a chance that the early Turks picked up certain West Eurasian lineages. The anthropological data I've seen thus far suggests they were Mongoloid-Caucasoid intermediates of some flavour. Combined with the penetration of West Eurasian lineages even into Central China, I'd say it's most probable they carried West Eurasian Y-DNA/mtDNA.<br /><br />Haplogroup L is poorly researched because it does not currently fit the scope of interest currently held by academia, who are preoccupied with Y-DNA R1a, R1b, I and J at present.DMXXhttps://www.blogger.com/profile/16689998564656086919noreply@blogger.comtag:blogger.com,1999:blog-2845420051498655579.post-58893827191548253082012-06-19T12:31:46.934-07:002012-06-19T12:31:46.934-07:00L1-M27(L1a) is West Eurasian.

We are fortunate to have a wealth of much-needed haplotypes from the other ethnic groups in the country. The last time "Tajiks" had received the limelight was through Zerjal et al., which basically re-examined Dr. Wells' seminal paper on Central Asia a couple of years later.<br /><br />@Vasishta,<br /><br />Whichever deep ancestral criterion we use to project autosomal DNA results from lead us to the same conclusion.<br /><br />Based on the Afghan Pashtun Y-DNA presented in this paper, they will likely turn out to be more West Eurasian than their Pakistani counterparts based on elevated frequencies of R1a1a-M17 and less/no L1-M27 and O-M175-derived subclades. Please note the inflated frequencies of L1c-M357 and Q*-M242 among the Afghan Pashtuns are the result of genetic drift (I concluded this safely with the latter but did observe greater STR variation in the former).<br /><br />Although no maternal (mtDNA) data was supplied with this paper, we can predict the Afghan Pashtuns will again turn out to be more West Eurasian based on previous studies, <a href="http://www.ncbi.nlm.nih.gov/core/lw/2.0/html/tileshop_pmc/tileshop_pmc_inline.html?title=An%20external%20file%20that%20holds%20a%20picture%2C%20illustration%2C%20etc.%0AObject%20name%20is%20AJHGv74p827fg1.jpg%20%5BObject%20name%20is%20AJHGv74p827fg1.jpg%5D&p=PMC3&id=1181978_AJHGv74p827fg1.jpg" rel="nofollow">where geography appears to be (one of) the driving factors.</a>DMXXhttps://www.blogger.com/profile/16689998564656086919noreply@blogger.comtag:blogger.com,1999:blog-2845420051498655579.post-49171829374033546042012-03-30T03:48:36.900-07:002012-03-30T03:48:36.900-07:00There is another flaw in the study i.e., the under...There is another flaw in the study i.e., the under-testing of Pashtun and Tajak populations (Tajak: 53 samples for population proportion of 27%; Pashtun 49 samples for a population proportion of 42%) and over-testing of Hazaras(60 samples for a population proportion of 9%). Also worth-noticing is the fact that no Pashtun from the core Pashtun region like Kandahar has been tested and most of the Pashtun samples have been taken from Afghanistan's north (very few samples from Afg south where most of Pashtuns are concentrated).Barakhttps://www.blogger.com/profile/01270311169277810090noreply@blogger.comtag:blogger.com,1999:blog-2845420051498655579.post-88920626581271148272012-03-30T02:04:29.355-07:002012-03-30T02:04:29.355-07:00Excellent assessment.
