ABSTRACT Mitochondrial DNA (mtDNA) polymorphism has been studied systematically in the Han, Tibeto- Buman, and Hmong-Mien ethnic families of southern East Asia. Only two families in this region, Daic and Aus- tro-Asiatic, were still uninvestigated. Daic is a major ethnic family in South China and Southeast Asia and has a long history. To study mtDNA polymorphism within this family, all the Daic populations of China and some of Vietnam (774 individuals from 30 populations) were typed by HVS-1 region sequencing and by PCR-RFLP assays. The observed high Southern type frequencies (B, F, M7, R) confirmed Daic as a typical Southern group. mtDNAs of other populations (126 individuals from 14 populations) from Austro-Asiatic ethnic families neighboring the Daic were also typed. Networks of mtDNA haplogroups in South China were traced from these new data and those from the literature. Ethnic families share many hap- logroups, indicating their common origin. However, the two largest families in South China, Daic, and Hmong- Mien, polarized into several ethnic family specific haplogroups. Haplogroup ages were estimated in the networks of high-frequency haplogroups (B, F, M7, R), and they were found to originate about 50,000 years ago. In contrast, ethnic family specific haplogroups all originated around 20,000 years ago. We therefore conclude that modern humans have lived in South China for a long time, inside-ethnogenesis was a rather late event, and frequent inmixing was taking place throughout. MtDNA data of Daic, Austro-Asiatic and other populations in South China has therefore proven pivotal for studying the human history of East Asia.

摘要:在系统地研究了东亚南部的汉族,藏缅族,苗瑶族表现出的线粒体DNA(mtDNA)多态性之后。只有这个地区的两个族群,壮侗语和南亚语族族群,还没有被调查。壮侗语族群是中国南方和东南亚的一个重要的民族,历史悠久。为了研究这个家族中的mtDNA多态性,我们通过HVS-1区域测序和PCR-RFLP分析,对中国和越南的一些壮侗语群体(来自30个群体的774个个体)进行分型。观察到高频率的南部类型分布(B,F,M7,R),证实壮侗语族群是一个典型的南方群体。其他人群(来自14个人群的126个个体)来自壮侗语族群附近的南亚族群的mtDNA也被分类。从这些新的数据和文献中可以追踪到中国南方线粒体DNA单倍群的网络。族群如果共享许多单倍群,证实他们有共同的起源。然而,中国南方最大的两个族群,壮侗语族群和苗瑶族群,则极化为几个不同的民族特定的单倍群。通过对高频单倍群(B,F,M7,R)的网络进行推算得出了单倍群的年龄,发现它们起源于大约5万年前。相比之下,各民族特有的单倍群都发源于两万年前。因此,我们得出结论:现代人类在中国南方地区长期生活,其中民族起源是一个相当晚的事件,并且经常发生混合。因此,中国南方的壮侗语,南亚和其他族群的MtDNA数据已经被证明是研究东亚人类历史的关键。

Modern humans have lived in South China for at least 30,000 years, since the age of the Liujiang Man, discovered in Guangxi, China, in 1958 (Wu, 1959). Genetic studies show that populations in North China derived from populations in South China (Su et al., 1999). A large number of anthropological studies suggested that South China is the motherland of many ethnic groups throughout East Asia and the Pacific. There have been migrations from South China to Southeast and Northeast Asia and other neighboring areas during prehistory and history. The most famous among these migrations was the migration of Austronesian populations, which are believed to have left the coast of South China about 6,000 years before the present (kybp) and spread throughout the Pacific (Zhang, 1987; Diamond, 1988; Bellwood et al., 1995). The genetic structure of populations in this area is, therefore, pivotal in forming of ethnic patterns in east Eurasia.

现代人类在中国南方至少有3万年的历史,自1958年在中国广西发现的柳江人(Wu,1959年)以来。遗传研究表明中国北方地区的种群来源于中国南方地区(Su等,1999年)。大量的人类学研究表明,中国南方地区是整个东亚和太平洋地区多民族的发源地。在史前和历史上,从中国南方到东南亚,东北亚等周边地区有过迁徙的历史。 在这些迁徙中最为着名的是南岛人口的迁徙,相信这种迁徙在距离现在6000年前已经离开中国南方海岸并传播到整个太平洋地区(Zhang,1987年; Diamond,1988年; Bellwood 等,1995年)。 因此,该地区人口的遗传结构是欧亚东部形成种族格局的关键。

There are many ethnic families besides Han Chinese in South China, such as the Daic, Hmong-Mien (HM), Tibeto-Burman (TB), Austro-Asiatic (AA), Taiwan aborigines (TA) and the Malayo-Polynesians (MP). Among these populations, the Daic (also called Baiyue in Chinese) is the largest and most widespread. The total population of the nine official Daic nationalities in China is 25.8 million (2000 census). However, the population of the Daic descendants assimilated by Han Chinese is most probably even larger than this number (Song, 1991). Moreover, there are about 80 million (Grimes, 2002) Daic in Thailand, Laos, Vietnam, Myanmar, and India who migrated from South China. So in size, the Daic population is second only to the Han, and is far larger than any other ethnic family in South China. Until the arrival of the Han (Wen et al., 2004a), the Daic were the aboriginal ethnic group of China's southeast coastal zone, which extends from Shanghai to Hanoi (Kuaiji to Jiaozhi, Song, 1991), although most of the Daic populations reside to the west of Hong Kong now. Thus, the genetic structure of the Daic is one of the most important parts of the study of South China's genetic structure.

除了汉族之外,中国南方地区还有很多民族,如壮侗语系族群,苗瑶族(Hmong-Mien,HM),藏缅族(Tibeto-Burman,TB),南亚语系族群(Austro-Asiatic,AA),台湾原住民(Taiwan aborigines,TA),马来-波利尼西亚族群(Malayo-Polynesians,MP)等。在这些人群中,壮侗语系族群(在中国也被称为百越)是人口最多和最广泛分布的。中国9个正式的壮侗语民族的总人口是2580万(2000年人口普查)。然而,被汉族同化的壮侗语族群的子孙的人口很可能比这个数字更大(Song,1991年)。此外,泰国,老挝,越南,缅甸和印度有从中国南部迁徙的大约有8000万壮侗语系人群(Grimes,2002)。所以大小人口仅次于汉族,远远超过中国南方的其他民族。直到汉人到来(Wen等,2004年,a),壮侗语系族群是中国东南沿海地区的原住民族,从上海延伸到河内(会稽至交趾,Song,1991年),尽管大部分的壮侗语族群人口现在居住在香港以西。因此,壮侗语族群的遗传结构是研究中国南方遗传结构最重要的部分之一。


Mitochondrial DNA is a powerful tool in population history studies, and it claims a vital role in global human population research (Shriver and Kittles, 2004). mtDNA in South Chinese populations is also being explored. Population data from certain areas have been reported in succession, especially data from the minorities of the Yunnan province in Southwest China (Yao and Zhang, 2002). Ethnic families are also being systematically investigated, and the first family investigation to be completed was that of TB. mtDNA polymorphisms of most of the TB populations in China were found to have a northern origin, while also having had absorbed a large proportion of southern lineages (Wen et al., 2004b). Han populations were also studied systematically, and a mixed structure, similar to that of TB, was found (Wen et al., 2004a). Similar studies were performed in the HM family, but these data show less mixing of northern lineages with the southern lineages (Wen et al., 2005). Data of TA have also been reported (Tajima et al., 2003).

线粒体DNA是人口史研究中的一个有力工具,它在全球人口研究中发挥了至关重要的作用(Shriver and Kittles,2004年)。也正在对中国南方人群的线粒体DNA进行研究。连续报告了某些地区的人群数据,特别是云南省西南少数民族的数据(Yao和Zhang,2002年)。对民族也正在进行系统的调查,第一个要完成谱系调查的是藏缅族(Tibeto-Burman,TB)。中国大部分TB人群的mtDNA多态性是北方起源的,同时也吸收了大量的南方血统(Wen 等,2004年,b)。对汉族人群也进行了系统的研究,发现了与TB相似的混合结构(Wen等,2004年,a)。在苗瑶民族(Hmong-Mien,HM)中进行了类似的研究,但是这些数据显示北部谱系与南部谱系的混合较少(Wen等,2005年)。 台湾原住民(Taiwan aborigines,TA)的数据也有报道(Tajima等,2003年)。

Overall, mtDNA research in South China is relatively complete, except for that of the major group, the Daic, and for the AA group in outlying regions. As is widely known, the Han and TB groups moved from Northern China (Su et al., 2000), and while the Han settled throughout South China, the TB settled mainly in remote areas of Southwestern China. The TA and MP groups, natives of South China, have smaller populations and now reside in the Southeast islands far from the mainland. Therefore, the ethnic groups of most relevance to our study in South China are the HM and Daic. Knowing their genetic structure would contribute to a full understanding of the original genetic structure of Southern China. Although the AA group is far to the Southwest, it is still of significant value as a reference population considering it is so ancient a group (the ancient distribution of groups mentioned above refers to Fig. 1). As a result, we will analyze the matrilineal genetic structure of South China by exploring the mitochondrial DNA polymorphisms of all Daic populations and many AAs, eventually combining our data with that from other groups.

总体而言,中国南方地区的线粒体DNA研究较为完整,除了主要群体,壮侗语族群,和边远地区南亚语系族群(AA)外,众所周知,汉族和藏缅族(TB)来自中国北方(Su等,2000年),汉族居住范围遍布中国南方,藏缅族(TB)主要集中在西南偏远地区。台湾原住民(TA)和马来-波利尼西亚族群(MP),中国南方的原住民,人口较少,现在居住在远离大陆的东南诸岛。因此,与我们的中国南方研究最相关的民族是苗瑶民族(HM)和壮侗语民族(Daic)。了解其遗传结构将有助于全面了解中国南方的原始遗传结构。尽管南亚语系族群(AA)组与西南地区相差甚远,但考虑到它是如此古老的一个群体(上文提到的群体的古代分布参见图1),作为参照群体仍然具有显著的价值。因此,我们将通过探索所有壮侗语民族(Daic)群体和许多南亚语系族群(AA)的线粒体DNA多态性来分析中国南方地区的母系遗传结构,最终将我们的数据与其他群体的数据结合起来。

Through the analysis of mtDNA, we expect to discover which mtDNA polymorphisms represent the matriline- age of South China, when they were formed, and how and when they branched out geographically. In this way, we hope to ascertain the timetable of modern human settlement and fragmentation in South China, and thus to provide a sturdy foundation for the original genetic structure of the whole of East Asia.

通过对线粒体DNA的分析,我们期望发现哪些线粒体DNA多态性代表了中国南方地区的母系时代,它们何时形成,怎样进行分支分布。如此我们希望能够确定中国南方现代人类居住和形成支系的时间表,从而为了解整个东亚的原始基因结构提供坚实的基础。

ISO639-3 is the international standard devised to enable the uniform identification of all known languages in a wide range of applications, particularly including information systems. For our sample populations these linguistic tags can be used to search Ethnologue (http://www.ethnologue.com) for information on the populations. Those codes with stars stand for the languages used by several populations beside our sample populations. The original languages of those sample populations have been replaced by the coded languages.

ISO639-3是国际标准,旨在使所有已知语言能够在各种应用中,尤其是信息系统中统一识别。 对于我们的样本群体,这些语言标签可以用来搜索《民族语》(Ethnologue)(http://www.ethnologue.com)。 那些带有星号的编码,代表我们样本族群以外被多个族群使用的语言。这些样本族群的原始语言已被编码语言取代。

MATERIALS AND METHODS

材料与方法

Blood samples of 774 individuals from 30 Daic populations across South China and Vietnam were collected with FTA cards (Whatman), covering almost all of the Daic populations in China. There are also 126 individuals from 13 AAs and one Sino-Tibetan population, bringing the total sample size to 900. All of the donors are unrelated and gave their consent to the study. The data from the populations studied is shown in Table 1.

采用FTA卡(Whatman)收集来自中国南方和越南的30个壮侗语族群(Daic)的774个个体的血液样本,覆盖中国几乎所有的壮侗语族群(Daic)群体。 还有来自13个南亚语系族群(AA)和一个汉藏人群的126人,使样本总数达到900人。所有的捐助者都是不相关的,并同意这项研究。表1列出了所研究人群的数据。

An mtDNA fragment containing the HVS-1 region was amplified by primers L15974 and H16488 (Yao et al., 2002a), and the purified PCR product was sequenced using the BigDye terminator cycle sequencing kit and an ABI 3100 genetic analyzer (Applied Biosystem). Primers were also designed for amplifying multiple fragments containing 12 RFLP polymorphisms in the coding regions, and most of the PCR products were digested by restriction enzymes: 9bp deletion, 10397 AluI, 10394 DdeI, 663 HaeIII, 5176 AluI, 4831 HhaI, 12406 HpaI, and 9824 HinfI (Kivisild et al., 2002; Yao et al., 2002a). The additional variations, 3010, 4715, 5417, and 10310, were geno- typed by directional sequencing or PCR-RFLP assay by engineering restriction sites in the primers (primer information and genotyping protocol for all the coding region variants are shown in Supplementary Table 1).

通过引物L15974和H16488(Yao等,2002年,a)扩增含有HVS-1区域的mtDNA片段,并使用BigDye终止子循环测序试剂盒和ABI 3100遗传分析仪(Applied Biosystem)对纯化的PCR产物进行测序。也设计引物以扩增编码区中含有12个RFLP多态性的多个片段,并且大多数PCR产物用限制性内切酶消化:9bp缺失,10397AluI,10394DdeI,663HaeIII,5176AluI,4831HhaI,12406HpaI, 和9824 HinfI(Kivisild等,2002年; Yao等,2002年,a)。 另外的变体3010,4715,5417和10310通过定向测序或PCR-RFLP测定通过引物中的工程限制性位点进行基因型分类(所有编码区变体的引物信息和基因分型方案见补充表1)。

The 464bp long HVS-1 sequences (16024-16488) were edited and aligned against the revised CRS (Andrews et al., 1999) using DNASTAR software (DNASTAR). All of the 900 HVS-1 sequences from 53 populations have been submitted to Genbank (Accession number: EF654716-EF655616).

使用DNASTAR软件(DNASTAR)对464bp长的HVS-1序列(16024-16488)进行编辑并与修订的CRS(Andrews等,1999年)比对。 来自53个群体的所有900个HVS-1序列已经提交给Genbank(登录号:EF654716-EF655616)。

Haplogroup affiliation of each mtDNA sequence was inferred by combined use of the HVS-1 motif and diagnostic variants in the coding regions following Kivisild et al. (2002) and Kong et al. (2003a). Median joining networks (Bandelt et al., 1999) were constructed by NETWORK software (www.fluxus-engineering.com) to investigate detailed lineage relationship within each haplogroup. Coalescence time and its standard error of the haplogroups were calculated by the methods developed by Forster et al. (1996) and Saillard et al. (2000), respectively. The reference data of other groups in East and Southeast Asia used in networks were obtained from the literature (Horai et al., 1996; Wen et al., 2003, 2004a,b, 2005; Qian et al., 2001; Yao and Zhang, 2002; Kivisild et al., 2002; Yao et al., 2002a,b, 2003, 2004; Tajima et al., 2003; Kong et al., 2003b), including that for the Daic, AAs, HMs, TAs, Sino-Tibetans, and some Altaic populations.

根据Kivisild等人(2002年)和Kong等人(2003年,a)的研究,通过在编码区中HVS-1基序和诊断变体的组合使用推断每个mtDNA序列的族群归属。中间连接网络(Bandelt等,1999年)是由NETWORK软件(www.fluxus-engineering.com)构建的,以研究每个单倍群内的详细的谱系关系。通过Forster等人(1996年)和Saillard等人 (2000年)开发的方法计算单倍群的聚并时间和标准误差。东亚和东南亚其他群体的参考数据来源于文献(Horai等,1996年; Wen等,2003年,2004年a,b,2005年; Qian等,2001年; Yao和Zhang ,2002年; Kivisild等,2002年; Yao等,2002年a,b,2003年,2004年; Tajima等,2003年; Kong等,2003年b),包括壮侗语族群(Daic),南亚语族群(AAs),苗瑶语族群(HMs),台湾原住民(TA), 汉藏语族群(Sino-Tibetans)和一些阿尔泰人(Altaic populations)。

RESULTS
结论

Distribution and specificity of haplogroups
单倍群的分布和特异性

Almost all of the samples were genotyped and their haplogroups were confirmed (Supplementary Table 2) (Table 2). The most common Daic haplogroups are B4a,F1a, M7b1, B5a, M7b*, M*, R9a, and R9b, in order of frequency, and the total percentage of these common haplogroups is 48.8%. In the remote AA populations, the most common haplogroups in order of frequency are F1a, M*, D*, F1b, N*, C, M7b*, M7b1, and F1a1a. This list is noticeably but unsurprisingly different from that of the Daic's. The percentage of the first three haplogroups for the AA populations alone totals 50.8%. The Daic's hap- logroup list is similar, however, to that of the HM's (B5a, B4a, M*, M7b*, C, B4b1, M7b1, F1a, B4*, and R9b, totaling 50.6%), and is based on these two Southern populations, the Daic and the HM (Wen et al., 2005), we can conclude that B, M7, F, and R are the most characteristically Southern haplogroups. Among Daic populations, the frequencies of these four Southern specific haplogroups total 66.4%, which is higher than the totals in either the AA population (48.9%) or the HM population (58.9%). Moreover, the frequency of these haplogroups is decreased in more northern populations, such as in the Han (40.8%), the more northern Tibeto-Burman (37.5%), and the northernmost Altaic (16.3%). These four haplogroups are, therefore, essential to the study of matrilineage in South China.

几乎所有的样本都进行了基因分型,并确认了它们的单倍群(补充表2)(表2)。最常见的壮侗语族群(Daic)单倍型依次为B4a,F1a,M7b1,B5a,M7b *,M *,R9a和R9b,这些常见单倍型的总比例为48.8%。在偏远的南亚语族群(AA)群体中,按频率次序,最常见的单倍群是F1a,M *,D *,F1b,N *,C,M7b *,M7b1和F1a1a。这个列表与壮侗语族群(Daic)的明显不同,但并不令人意外。仅南亚语族群(AA)群体的前三个单倍组的百分比总计为50.8%。 然而,基于壮侗语族群(Daic)和苗瑶语族群(HM)在南方的人口,壮侗语族群(Daic)的单倍群列表与苗瑶语族群(HM)(B5a,B4a,M *,M7b *,C,B4b1,M7b1,F1a,B4 *和R9b,共计50.6%)的列表相似(Wen 等,2005年),我们可以得出结论,B,M7,F和R是最具特征的南方单体群。在壮侗语族群(Daic)中,这四个南方特定单倍群的频率总和为66.4%,高于AA群体(48.9%)或HM群体(58.9%)。此外,在北部的汉族(40.8%),更北分布的藏缅族(37.5%)以及最北端的阿尔泰民族(16.3%),这些单倍群的频率有所下降。因此,这四个单倍群对于研究中国南方的母系遗传是至关重要的。

Network analysis of related groups
相关族群的遗传网络分析

To create networks in the Daic, AA, MP, HM, Sino- Tibetan, and Altaic populations, we used HVS-1 motifs (see Supplementary Table 2) from the haplogroups with high frequencies in South China (Fig. 2) as well as previously published haplogroup and HVS-1 data (Horai et al., 1996; Wen et al., 2003, 2004a,b, 2005; Qian et al., 2001; Yao and Zhang, 2002; Kivisild et al., 2002; Yao et al., 2002a,b, 2003, 2004; Tajima et al., 2003; Kong et al., 2003b). We marked each ethnic family in the network by color, but we separated the coastal Han, those from Shanghai to Guangxi, from the remaining population, taking into consideration that there may be a large number of Daic descendents in the coastal Southeastern Han populations, especially among the Southern specific hap- logroup ones.

为了在壮侗语族群(Daic),南亚语族群(AA),马来-波利尼西亚族群(MP),苗瑶语族群(HM),汉藏族群和阿尔泰族群中建立遗传网络,我们使用了来自中国南方地区高频率单倍群(见图2)的HVS-1基序(见补充表2) 以及先前发表的单倍群和HVS-1数据(Horai等,1996年; Wen等,2003年,2004年 a,b,2005年; Qian等,2001年; Yao和Zhang,2002年; Kivisild等,2002年; Yao等,2002年a,b,2003年,2004年; Tajima等,2003年; Kong等,2003年b)。我们用颜色标注了遗传网络中的每一个民族,但是我们把沿海的汉族,上海到广西的汉族与其余的人口分开,考虑到可能有大量的壮侗语族群后裔在东南沿海地区汉族内部,特别是在南方特有的单倍群中。

The networks contain large nodes with primary, secondary, and sometimes further branching representing shared haplogroups among ethnic families. The networks clearly show greater differences in haplogroups between Northern and Southern populations than between ethnicities. For example, some branches contain a variety of unrelated ethnic families who are geographically close. However, some haplogroups, such as M7b and B4-16140 (subhaplogroup under B4 with 16140 derived allele), remain approximately specific to one ethnic group, in this case the Daic. Han samples from the Southeast coastal zone are the closest to the Daic samples phylogenetically, sharing the most haplotypes. Although linkages, which is to say, haplogroup similarities, between the Daic and the HM are also common, there are still fewer linkages than between the Southeastern Han and Daic. The linkages between the Daic and the Han exist mostly in smaller branches, however; those between the Daic and the HM are more primary. Differentiation among the subfamilies of Daic is difficult. The Tai subfamily is especially varied, indicating a history of strong population expansion.

遗传网络包含大型的节点,拥有一级,二级,有时甚至是更进一步的分支,代表了民族之间共享的单倍群。这些网络清楚地显示出北方和南方人群之间的单倍群差异比民族差异更大。例如,一些分支包含地理上接近的各种不相关的民族。然而,一些单倍群,例如M7b和B4-16140(B4下带有16140个衍生等位基因的亚类群),大致保持特定存在于一个族群,即壮侗语族群(Daic)。来自东南沿海地区的汉族样本在系统发生学上与壮侗语族群(Daic)样本最为接近,共享最多的单倍型。尽管壮侗语族群(Daic)和苗瑶语族群(HM)之间的联系,即单倍群相似之处也是常见的,但与东南汉族与壮侗语族群(Daic)之间的联系相比仍然较少。壮侗语族群(Daic)和汉族之间的联系大多存在于较小的分支上,那些在壮侗语族群(Daic)和苗瑶语族群(HM)之间的联系更加原始。 壮侗语族群(Daic)亚族之间的分化是很困难的。台语亚族群特别多样,表现出人口强劲增长的历史。

Time estimate
时间推算

We conducted time estimates of the approximate age of several relatively high-frequency branches in specific haplogroups of the South China populations. The results have a standard deviation of about 1/3. R is a primary haplogroup that branches off about 70,000 years ago, while branches for B, F, and M7 are each around 50,000 years old. Most other ancillary branches are 40,000 years old. There is not much contradiction for the corresponding relationship between the phylogenesis of haplogroup and branch age. For the age of each branch and the phylogenic tree refer to Figure 3.

我们对中国南方地区特定人群中几个较高频率分支的近似年龄进行了时间估计。结果有大约1/3的标准偏差。R是大约7万年前分支的主要单倍群,而B,F和M7的分支每个都在5万年左右。大多数其他辅助分支的年龄是4万年。 单倍群系统发生与分支年龄的对应关系并不矛盾。对于每个分支和系统发育树的年龄参考图3。

图3中国南方mtDNA谱系的年龄和气候变化。用黑方块标注的亚单倍群具有种族特异性。三种不同的背景表明三个民族发展阶段; 最黑暗的背景代表了民族分化的时期。温度变化显示在左边。所有的种族特异性亚单倍群都出现在Wiirm冰川期的最后一个冰段。

In the root nodes at the very base of the network, the HM and the Daic are not differentiable. However, in the first ancillary branches where differentiations begin to occur, the groupings are extremely HM or Daic specific, with no more than one outlier per branch. All of the hap- logroups with ethnic distinctions differentiated within the last 30,000 years, and most differentiated within the last 20,000. The largest ethnic specific haplogroups became distinguishable no more than 10,000 ago, which is also about when the most terminal ends of the networks differentiated. The population fragmentation in the terminal ends is obvious. According to the time table in Figure 3, the mtDNA lineage history generally falls into three phases, the first around 55-25 kybp, the second from 25-9 kybp, and the third from 9 kybp present.

在网络最底层的根节点,苗瑶语族群(HM)和壮侗语族群(Daic)是不可区分的。 然而,在第一个辅助分支开始发生分化时,这些分组非常具有苗瑶语族群(HM)或壮侗语族群(Daic)特征,每个分支不超过一个异常值。 所有具有民族差异的遗传组都在最近3万年内才有所区别,在最近2万年内差异最大。最大的种族特定单倍群在不超过1万年前才可以区分,这也是大多数遗传网络终端的差异时期。终端的人口分化是明显的。根据图3中的时间表,mtDNA谱系历史一般分为三个阶段,第一个在5.5-2.5 万年前,第二个从2.5-0.9 万年前,第三个从0.9万年前到现在。

The Daic contain most Southern specific mtDNA haplotypes
壮侗语系族群含有大部分南方特有的mtDNA单倍型

mtDNA haplogroup distribution in South and North China is obviously unequal (Yao et al., 2002a; Kong et al., 2003a; Wen et al., 2004a,b, 2005), and the hap- logroups B, M7, F, R, which are common in South China, are clearly of Southern origin. These Southern hap- logroups exist in high frequencies in the Daic, HM, and AA populations, indicating that these three ethnic families are native to South China. The Daic are acknowledged to be the descendants of the Baiyue, a famous, ancient ethnic family, which according to Chinese historical records lived in the coastal zone that now exists between Shanghai and Hanoi 2,000 years ago. This family, in turn, descended from the most powerful ethnic family in South China 8-2,000 years ago (Song, 1991). Their ancestors had comparatively advanced cultures (Song, 1991) (Hemudu Culture, Liangzhu Culture, etc) in these areas during prehistory, and they may have lived in South China for at least 30,000 years. When the Han began to expand southward in 2 kybp (Wen et al., 2004a), a large number of the Baiyue were assimilated by the Han. Others migrated westwards to become today's Daic populations. Thus, we can find a high proportion of mtDNA haplogroups similar to the Daic in southeastern Han populations.

中国南方和北方地区的mtDNA单倍型群体分布明显不相同(Yao等,2002年a; Kong等,2003年a; Wen 等,2004年a,b,2005年),而单倍群B,M7,F,R ,在中国南方很常见,显然是南方的起源的。在壮侗语族群(Daic),苗瑶语族群(HM)和南亚语族群(AA)群体中,这些南部单倍群群以高频率存在,表明这三个族群是原产于中国南方的。壮侗语族群(Daic)被公认为是著名的古代民族百越的后裔,根据中国的历史记载,这个族群两千年前生活在上海和河内之间的沿海地区。这个族群也就是8000-2000年前中国南方最强大的民族(Song,1991年)。他们的祖先在史前时期在这些地区有比较先进的文化(Song,1991年)(河姆渡文化,良渚文化等),他们可能在中国南方地区至少有3万年的生活史。当汉族开始向南扩张(Wen等,2004年a)时,大量的百越人被汉族同化。其他人向西迁移,成为今天的壮侗语族群(Daic)人口。因此,我们可以发现汉族东南部人群中与壮侗语族群(Daic)类似的高比例线粒体单倍群。

The Daic population has been shown to have a prominent place in population studies of South China, and ancient DNA from archaeological sites in the southeastern coastal zone can be used to better trace the footprints of the Daic's ancestors. These studies could reveal much of the population history in the entire Southern region.

壮侗语族群(Daic)人口在中国南方地区的人口研究中显示出了显著的地位,东南沿海地区考古遗址中的古代DNA可以用来更好地追溯壮侗语族群(Daic)祖先的遗迹。这些研究可以揭示整个南方地区的大部分人口历史。

Among the Daic, the HM, and the AA groups, the Southern haplogroup frequency is highest in the Daic and lowest in the AAs, although the AAs are nevertheless regarded as a native Southwestern population. The overall frequencies of B, M7, F, R are high in the Southeast but become lower in the populations to the northwest. We therefore conclude that the Daic, the HM, and the AA haplogroups are Southeast specific rather than South China specific.

在壮侗语族群(Daic),苗瑶语族群(HM)和南亚语族群(AA)中,南部单倍群频率在壮侗语族群(Daic)中最高,在南亚语族群(AA)中最低,尽管南亚语族群(AA)仍被认为是西南地区的本地人。东南部的B,M7,F,R总体频率较高,西北部则较低。 因此,我们得出结论,壮侗语族群(Daic),苗瑶语族群(HM)和南亚语族群(AA)单倍群是东南特异性的,而不是中国南方特有的。

One explanation why these Southern specific haplogroups seem to gather in the Southeast might be that the AA population in Southwest China was affected by TB returning from the North, thus reducing much of the Southern specificity. However, the Han and the TB populations share a geographic origin and were indistinguishable before their southward migration, so any affect the TB population may have had on the AA should be relatively equal to the effect the Northern Han had on the Daic. Noticeable differences between the AA and the Daic should therefore not occur, but they do. Another explanation may be that because modern humans entered South China by more than one route and because the few original populations in South China were very small, independent genetic drift would have taken place in the populations of East and West transmigrants. Southern specific haplogroups then randomly became plentiful in the East while there were relatively few in the West. It is possible that we, therefore, find many fewer southern haplogroups in the Northern populations because they arose from the Western populations, and the difference in frequencies of Southern specificity is traceable to this day.

为什么似乎这些南方特定的单倍群聚集在东南地区,一个解释可能是中国西南地区的南亚语族群(AA)人群受到从北方返回的藏缅族(TB)的影响,因此降低了大部分的南方特异性。然而,汉族和藏缅族(TB)人群在南迁前是共有地理起源的,难以区分的,所以任何藏缅族(TB)人群对南亚语族群(AA)人群的影响都应该与北方汉对壮侗语族群(Daic)的影响相当。南亚语族群(AA)和壮侗语族群(Daic)之间的显著差异因此不应该发生,但事实却是这样。另一种解释可能是因为现代人类通过一条以上的路线进入中国南方,由于中国南方地区的原始人口很少,所以在东,西移民的人口中就会发生独立的遗传漂变。南方特定的单倍群随后在东部随机变得丰富,而在西部则相对较少。因此,我们有可能在北方族群中发现少得多的南方单倍群,因为它们起源于西部族群,南方特异性的频率差异可追溯至今天。

History of modern East Asian's entry into South China
现代东亚人进入中国南部的历史

Because the four main haplogroups (B, M7, F, R) are all around 50,000 years old, the ancestor groups of modern East Asians likely differentiated at that time when the original mutations were formed. However, these ancestors still had probably not settled in East Asia at that point. The genetic data must be compared to other anthropological evidence to give an estimate for the time of the modern East Asians' entry into South China. According to palaeoanthropological evidence, this must have taken place more than 30 kybp. As a result, the migration should have taken place in the period between 50 and 30 kybp, which is consistent with the research on the East Asian Y chromosome (Jin and Su, 2000). After the first settlement of modern East Asians in South China, there was a long pause before the diversification of populations occurred.

由于四种主要的单倍型群(B,M7,F,R)都在5万年左右,所以现代东亚人的祖先群体在原始突变形成时可能发生了分化。但是,这些祖先在这个时候可能还没有定居在东亚。遗传数据必须与其他人类学证据相比较,以估计现代东亚人进入中国南方的时间。根据古人类学的证据,这一定发生在超过3万年前。因此,迁移应在5-3万年间进行,这与东亚Y染色体的研究一致(Jin 和 Su,2000年)。在中国南方地区现代东亚人第一次定居之后,人口分化发生之前有一个很长的停顿时期。

Population fragmentation
人群的分化

Basing on our research, the fragmentation of Southern Chinese populations began around 20 kybp, when ethnically specific haplogroups were formed. Low population density, which allowed all of the original migrants to remain in the southernmost part of China, may be one reason that the population did not differentiate earlier or upon their arrival. Population growth around 20 kybp may then have caused the subsequent differentiation. Inmixing between groups, however, was still quite common. Therefore mtDNA haplogroups, even some of those branching later than 20, 000 years ago, were still found in a wide range of ethnic groups. In fact, the populations may well have diverged geographically before 20 kybp, but the high frequency of inmixing may have homogenized the population's haplotypes. However, after about 20 kybp, the genetic exchange was almost cut off, either by natural or social factors or a mixture of the two. No specific social cause is known, but a natural disaster in the form of the peak of a glacial age may well have been the cause of the sudden end of genetic inmixing (Fig. 3, Shi et al., 1989).

在我们的研究基础上,中国南方人群的分化始于约2万年前,当时形成了种族特异性单倍群。人口密度低,使所有原来的移民都能够留在中国最南端,这可能是造成人群没有紧接着他们到达,更早的分化的原因之一。2万年前左右的人口增长可能导致了随后的人群分化。然而,群体之间的混合还是相当普遍的。因此,线粒体DNA单倍群,甚至一些分支晚于2万年的单倍群,仍然广泛的存在于各族群中。事实上,在2万年前,人口在地理上可能已经发生了分歧,但是高频混合可能已经使群体的单倍型同质化。然而,在约2万年前以后,遗传交换几乎被切断,无论是自然因素还是社会因素,或是两者的混合。没有已知的具体的社会原因,但冰川高峰期的自然灾害很可能是基因混合突然结束的原因(图3,Shi等,1989年)。

The freezing weather very likely not only reduced communication between populations but also may have altered their conditions of survival. The original modern East Asian was probably forced to move to different areas segregated by the cordilleras (Fig. 1), and this segregation was apt to spur the gradual shaping of the diversity between populations afterwards. The differentiation was culturally magnified over 10,000 years concomitant with ever less genetic communication, and the presently observed diversity of populations, represented by the Daic, the HM, and the AA of South China, was finally formed. Two most important archaeological cultures, Hemudu and Daxi, formed in the region of the Daic and the HM, respectively, around 8 kybp. Based on mtDNA data, population mixing has never fully stopped, so the differences that exist among the AA, HM, and Daic are still increasing, albeit very slowly. Unsurprisingly, then, the groups closest geographically are also comparatively close in mtDNA haplotype data. This interchange not only takes place among Southern groups, but also occurs between Southern and Northern groups and is likely more frequent between the Northern groups moving southwards and the Southern aboriginal groups already there.

寒冷的天气很可能不仅减少了人们之间的交流,而且可能改变了他们的生存条件。最初的现代东亚人可能被迫迁移到由山脉隔离的不同地区(图1),而这种隔离往往会促使人口之间多样性的逐渐形成。这种差异在文化上被放大了1万多年,伴随着更少的基因交流,最终形成了目前中国南方以Daic,HM和AA为代表的人口多样性。两个最重要的考古学文化,河姆渡和大溪,分别形成于Daic和HM地区,大约在八千年前。基于mtDNA数据,种群混合从来没有完全停止过,所以AA,HM和Daic之间的差异仍然在增加,尽管非常缓慢。不出所料,那么地理上最接近的组在mtDNA单倍型数据上也相对接近。这种交流不仅发生在南方群体之间,而且也发生在南方和北方群体之间,在向南迁徙的北方群体和南方原住民群体之间可能更为频繁。

Much information can be obtained about the original settling of South China and the subsequent differentiations of its populations using mtDNA polymorphisms. However, mtDNA only shows the matrilineal genetic history of South China. The genetic information to be gleaned from South Chinese Y-chromosomes might reflect a very different genetic structure, and is, therefore, a vital complement to mitochondria research.

可以通过mtDNA多态性研究获得关于中国南方地区原始定居及随后族群分化的很多信息。 但线粒体DNA仅显示了中国南方地区的母系遗传史。从中国南方Y染色体收集的遗传信息可能反映了一个非常不同的遗传结构,因此是线粒体研究的重要补充。

亚瑟王与圆桌骑士的故事(转载

导读:很久以前,魔王给亚瑟王出了道题,他必须在一年内回答出:女人最渴望得到什么?如果答对了,他就可以活下去,否则在这一年的最后一天,他就得死:“女人最想得到什么?”

大家议论纷纷,金钱、爱情、美貌、权势……但亚瑟王都觉得不对。时限眼看就到了,有人告诉亚瑟王在城里的女巫一定知道答案。亚瑟王无奈,就带了他最好的朋友——圆桌骑士去请教女巫。女巫如众人所说的一样。

女巫说:“如果要我说出答案,必须先答应我一个条件。”女巫的条件是要那位最英俊、智慧的圆桌骑士娶她为妻。亚瑟王绝对不同意他最好的朋友娶这样一个又老又丑的女巫。

但圆桌骑士却说,为了亚瑟王的宝贵生命,他愿意娶女巫为妻。于是女巫就告诉亚瑟王,女人最渴望的是掌握自己的命运。魔王认为亚瑟王的回答很正确,因此解除了对他的咒语,亚瑟王也履行自己的承诺——为圆桌骑士和女巫举办婚礼。婚礼上,人人都惋惜最英俊的男子竟娶了这样一个丑老太婆,但圆桌骑士却泰然处之,没有表现出对女巫的任何一点厌恶。

晚上圆桌骑士进入洞房,却看见一个美如天仙的少女。原来女巫有两个化身:一个是丑陋的巫婆,另一个是美丽的少女。女巫告诉圆桌骑士,现在圆桌骑士有选择的权利:希望她的妻子白天是美丽的少女呢?还是晚上是?如果白天是,那么圆桌骑士在朋友面前会非常荣耀,受到人们的艳羡。但晚上又如何面对一个丑陋的老妇,而且还要与她同床共枕?如果晚上是,与美丽的妻子屏烛相对将是人生的最大欢乐。但白天他如何与一个丑老太婆手挽手出现在众人的面前?

——如果你是圆桌骑士会怎么选择呢?

圆桌骑士回答:“你的命运由你自己来决定!”他没有忘记,女人最渴望掌握自己的命运。

结果女巫幸福的哭了“我爱你,我选择白天晚上都美丽!”
