1. 关于R9a:
Yao YG, Kong QP, Bandelt HJ, Kivisild T, Zhang YP. Phylogeographic differentiation of mitochondrial DNA in Han Chinese. Am J Hum Genet. 2002 Mar; 70(3):635-51论文中的R9a后来被归入F3,现在R9的谱系结构是R9分出R9b, R9c和F

在R9a的原始出处的论文中,作者明确写出新疆的两例R9a是由于近期的移民原因:
The spread of Han people to Yunnan, Xinjiang, and Taiwan happened relatively recently—within the past several hundred years. For the Yunnan Han, according to historical records, many movements were caused by an expansion policy, especially during the Ming dynasty (1368–1644 a.d.) (Ge et al. 1997). Since at that time the local population density was very high, the relative contribution of the Han to the local gene pools was overall rather minor, although eventually Han culture was generally accepted. Therefore, the genetic makeup of the Yunnan Han should show more influence from the autochthonous people than that of Han people from their early historical homelands in the basins of the Yellow River and the Yangtze River (see Du et al. 1998). The Taiwanese and Xinjiang Han have similar demographic histories: after World War II, both populations received a heavy influx of Han people from across almost all of China. However, before the withdrawal of the Guomingtang, Han people from the proximal Fujiang and Guangdong provinces and other parts of China continually migrated to Taiwan, with two main waves arriving in the 18th and 19th centuries (Ge et al. 1997). The high frequencies of haplogroups F1a and M7b in the Taiwanese Han, if not an autochthonous signal, might well reflect this connection with south mainland China, whereas other haplogroups—such as G2 and Y, mainly present in the north—hint at recent migrations from north and northeast China. The presence of two R9a types in Xinjiang (incidentally matching the two R9a haplotypes from Hong Kong; Betty et al. 1996), as well as the M7b haplotypes, point to connections with south and southwest China, where R9a and M7b are prevalent. On the other hand, the relatively high percentage of haplogroups A, C, and Z in this population may stem from recent migrations of Han people from central and east China to Xinjiang Province during the 1950s and 1960s. Evidence for recent migration is also reflected by the fact that no west Eurasian mtDNA types were found in the Xinjiang Han, whereas, among the Uygurs and Kazakhs from the same geographic areas (Yao et al. 2000a), >30% of individuals belong to west Eurasian haplogroups (Macaulay et al. 1999). https://www.ncbi.nlm.nih.gov/pmc/articles/PMC384943/

楼顶是王 @wang 自己的马甲在自问自答自导自演吧。
以R9bR9c为由扯什么F上游R9在什么东南亚,那以E为由扯M9a上游M9都是东南亚种有何不可?何况你这不识字不看文章的文盲东南亚的R9b和R9c年龄才多大你怎么不敢说?新疆独特的老R9a你怎么不敢说?西北那些零星独特的R9以及R11你怎么不敢说?R9bR9c在东南亚跟R9能有什么关系?请问R9年龄是多少年?谁告诉你R9xF都在东南亚的?R9b和R9c是F的平行支系,什么时候变成F的上游了?R9b和R9c在东南亚与F能有什么关系?就像P164*在东南亚与M134能有什么关系?什么年代的所谓“共祖”?不考虑年龄的话倒退五万年中国人都是马来猴后裔!你拿东南亚的R9b'c来论证R9是东南亚起源,咋不敢扯新疆的老R9a?咋不敢扯你M9a的亲戚E不在菲律宾马来猴里么M9根部类型M在东南亚有一堆你怎么不扯?
按着你的说法,母系mt-M9的起源地肯定与菲律宾的E极近,典型尼格利陀种
在guokr看过你照片的肤色五官就知道你活该是mt-M标准老亚洲种
