    黄河三角洲在中国新石器时代文明的发展中起着至关重要的作用。然而,由于缺乏古代人类基因组,该地区从新石器时代过渡到现在的人口历史仍然知之甚少。这尤其适用于新石器时代的关键过渡和王朝历史的混乱转折。这里,我们报告了来自69个个体的全基因组数据,这些数据可追溯到存在前5,410-1,345年(BP),覆盖范围为0.008至2.49倍,以及从山东16个城市收集的325名现今个人。在大汶口中后期,我们观察到中国中部新石器时代的黄河农民和一些南方的祖先大量涌入,这些祖先与山东当地的狩猎采集者混合在一起。山东龙山人的遗传遗产与大汶口文化联系最紧密。商周时期,有证据表明,龙山当地人口与中原移民的遗传混合。秦汉以后,该地区的遗传组成开始类似于现代山东人口。我们的遗传发现表明,在新石器时代中后期,黄河流域中部的农民在塑造中国北方邻近种群的遗传亲和力方面发挥了作用。此外,我们的发现表明,周代山东地区的遗传多样性可能与其复杂的种族有关。
    The Yellow River Delta played a vital role in the development of the Neolithic civilization of China. However, the population history of this region from the Neolithic transitions to the present remains poorly understood due to the lack of ancient human genomes. This especially holds for key Neolithic transitions and tumultuous turnovers of dynastic history. Here, we report genome-wide data from 69 individuals dating to 5,410-1,345 years before present (BP) at 0.008 to 2.49× coverages, along with 325 present-day individuals collected from 16 cities across Shandong. During the Middle to Late Dawenkou period, we observed a significant influx of ancestry from Neolithic Yellow River farmers in central China and some southern Chinese ancestry that mixed with local hunter-gatherers in Shandong. The genetic heritage of the Shandong Longshan people was found to be most closely linked to the Dawenkou culture. During the Shang to Zhou Dynasties, there was evidence of genetic admixture of local Longshan populations with migrants from the Central Plain. After the Qin to Han Dynasties, the genetic composition of the region began to resemble that of modern Shandong populations. Our genetic findings suggest that the middle Yellow River Basin farmers played a role in shaping the genetic affinity of neighboring populations in northern China during the Middle to Late Neolithic period. Additionally, our findings indicate that the genetic diversity in the Shandong region during the Zhou Dynasty may be linked with their complex ethnicities.

    山东省,位于黄河下游,是中国古代文明的发祥地之一。然而,到目前为止,由于缺乏古代人类基因组,该地区的综合遗传历史在很大程度上仍然未知。这里,我们展示了从战国到金元时期山东的21个古代基因组。与山东新石器时代早期的样本不同,历史样本与黄河中游新石器时代后期人口关系最密切,表明山东从新石器时代到历史时代的人口流动。此外,我们检测到山东的历史样本与当今的汉族人之间有密切的遗传亲和力,至少在战国时期以来,汉族人表现出长期的遗传稳定性。
    Shandong province, located in the Lower Yellow River, is one of the birthplaces of ancient Chinese civilization. However, the comprehensive genetic histories of this region have remained largely unknown until now due to a lack of ancient human genomes. Here, we present 21 ancient genomes from Shandong dating from the Warring States period to the Jin-Yuan Dynasties. Unlike the early Neolithic samples from Shandong, the historical samples are most closely related to post-Late Neolithic populations of the Middle Yellow River Basin, suggesting a population turnover in Shandong from the Neolithic Age to the Historical era. In addition, we detect a close genetic affinity between the historical samples in Shandong and present-day Han Chinese, showing long-term genetic stability in Han Chinese at least since the Warring States period.

    中国南北朝时期(公元3-6世纪)标志着中国北方民族融合的重要时代。然而,以前的古代DNA研究主要集中在北方民族,由于对遗传性精英家族遗传形成的研究有限,特别是考虑到他们丰富的考古记录和清晰的物质身份。在这项研究中,我们获得了一个遗传性精英家庭的古老基因组,高斌(,503-572AD),在1240k面板上覆盖0.6473倍,具有475132个单核苷酸多态性(SNP)。他的线粒体单倍群属于Z4,Y-单倍群属于O1a1a2b-F2444*。高斌的遗传特征与北方汉族最为相似。他可以被建模为从新石器时代晚期到铁器时代的黄河农民的所有祖先,而不受东北亚的影响,韩国,或者蒙古高原。我们的研究揭示了南北朝种族融合背景下遗传性精英家庭的遗传形成。
    China\'s Northern and Southern Dynasties period (3rd-6th centuries AD) marked a significant era of ethnic integration in northern China. However, previous ancient DNA studies have primarily focused on northern ethnic groups, with limited research on the genetic formation of the hereditary elite family, especially considering their abundant archaeological record and clear material identity. In this study, we obtained the ancient genome of a hereditary elite family, Gao Bin (, 503-572 AD), at 0.6473-fold coverage with 475132 single-nucleotide polymorphisms (SNPs) on the 1240k panel. His mitochondrial haplogroup belonged to Z4 and Y-haplogroup to O1a1a2b-F2444*. The genetic profile of Gao Bin was most similar to that of the northern Han Chinese. He could be modelled as deriving all his ancestry from Late Neolithic to Iron Age Yellow River farmers without influence from Northeast Asia, Korea, or the Mongolian Plateau. Our study sheds light on the genetic formation of hereditary elite families in the context of the Southern and Northern Dynasties ethnic integration.

    面部形态学,受遗传影响的复杂特征,在进化研究中具有重要意义。然而,由于化石证据有限,尼安德特人和丹尼索瓦人的面部特征在很大程度上仍然未知。在这项研究中,我们进行了大规模的多种族基因组关联研究(GWAS)的荟萃分析,包括9674名东亚人和10115名欧洲人,使用3D面部图像定量评估78个面部特征。我们确定了71个与面部特征相关的基因组基因座,包括21个新基因座。我们开发了一种面部多基因评分(FPS),可以根据遗传信息预测面部特征。有趣的是,FPS在不同大陆群体人群中的分布与观察到的面部特征显着相关。此外,我们用FPS来预测七个尼安德特人和一个丹尼索瓦人的面部特征,并将预测与化石记录保持一致。我们的结果表明,尼安德特人和丹尼索瓦人可能有相似的面部特征,例如更宽但更短的鼻子和更宽的内生距离。在Denisovan中特别表征了口腔宽度的减小。基因组数据和面部特征分析的整合为人类面部形态的进化史和适应性变化提供了有价值的见解。
    Facial morphology, a complex trait influenced by genetics, holds great significance in evolutionary research. However, due to limited fossil evidence, the facial characteristics of Neanderthals and Denisovans have remained largely unknown. In this study, we conducted a large-scale multi-ethnic meta-analysis of the genome-wide association study (GWAS), including 9674 East Asians and 10,115 Europeans, quantitatively assessing 78 facial traits using 3D facial images. We identified 71 genomic loci associated with facial features, including 21 novel loci. We developed a facial polygenic score (FPS) that enables the prediction of facial features based on genetic information. Interestingly, the distribution of FPSs among populations from diverse continental groups exhibited relevant correlations with observed facial features. Furthermore, we applied the FPS to predict the facial traits of seven Neanderthals and one Denisovan using ancient DNA and aligned predictions with the fossil records. Our results suggested that Neanderthals and Denisovans likely shared similar facial features, such as a wider but shorter nose and a wider endocanthion distance. The decreased mouth width was characterized specifically in Denisovans. The integration of genomic data and facial trait analysis provides valuable insights into the evolutionary history and adaptive changes in human facial morphology.

    这项研究分析了石虎窑墓葬出土的马遗骸中的古代DNA。这些发现可追溯到新疆汉唐时期(大约2200至1100年前)。获得两个高质量的线粒体基因组并使用下一代测序进行分析。基因组被分成两个母体单倍群,B和D,根据一项包括欧亚大陆古代和当代样本的研究。根据原始马单倍型G1,唐代马与Akhal-Teke马之间观察到了紧密的遗传亲和力。历史证据表明,古代丝绸之路在其传播中起着至关重要的作用。此外,获得了Akhal-Teke马的母系历史,并表明该品种的早期驯化是出于军事目的。
    This study analyzed ancient DNA from the remains of horses unearthed from the Shihuyao tombs. These were found to date from the Han and Tang Dynasties in Xinjiang (approximately 2200 to 1100 years ago). Two high-quality mitochondrial genomes were acquired and analyzed using next-generation sequencing. The genomes were split into two maternal haplogroups, B and D, according to a study that included ancient and contemporary samples from Eurasia. A close genetic affinity was observed between the horse of the Tang Dynasty and Akhal-Teke horses according to the primitive horse haplotype G1. Historical evidence suggests that the ancient Silk Road had a vital role in their dissemination. Additionally, the matrilineal history of the Akhal-Teke horse was accessed and suggested that the early domestication of the breed was for military purposes.

    养猪业通常被认为是集约化的畜牧业,主要由商品猪品种之间的杂交育种支持。然而,人们对更自然的环境和更高的肉质的追求导致对生态友好和多样化的猪饲喂系统的需求不断增加。因此,饲养和保护当地猪品种的重要性日益增加。Livni猪是一种当地品种,对俄罗斯中部的环境和饲料条件具有良好的适应性。在这项研究中,我们旨在利用全基因组单核苷酸多态性(SNP)数据分析Livni猪的遗传多样性和种群结构.我们将猪GGPHDBeadChip用于老年(2004年n=32)和现代(2019年n=32)Livni猪种群的基因型样本。对于Livni猪的博物馆样本(n=3),我们从他们的牙齿提取DNA,进行基因组测序,并从全基因组序列中获得SNP基因型。纳入长白猪(n=32)和大白猪(n=32)的SNP基因型进行比较分析。我们观察到Livni猪的等位基因丰富度高于长白猪和大白猪(AR=1.775-1.798vs.分别为1.703和1.668)。有效种群规模估计(Livni猪的NE5=108,长白猪和大白猪的NE5=59)证实了它们的遗传多样性趋势。纯合性运行的长度和数量进一步支持了这一点,以及基因组近交系数(与长白猪和大型白猪相比,Livni猪几乎低两倍)。这些发现表明,与商业猪种群相比,Livni猪种群表现出更高的遗传多样性,并且选择压力较低。此外,主成分和网络树分析均表明Livni猪和跨界商品猪之间存在明显差异。TreeMix结果表明,基因从长白祖先流向Livni猪(2019年),从大型白人祖先流向Livni猪(2004年),这与他们各自的历史育种背景是一致的。博物馆的比较分析,老,现代Livni猪表明现代Livni猪种群保留了其历史基因组成分,表明它们对未来设计选择计划的潜在适用性。
    The pig industry is usually considered an intensive livestock industry, mainly supported by hybrid breeding between commercial pig breeds. However, people\'s pursuit of a more natural environment and higher meat quality has led to an increasing demand for eco-friendly and diverse pig feeding systems. Therefore, the importance of rearing and conserving local pig breeds is increasing. The Livni pig is a local breed with good adaptability to the environmental and fodder conditions in central Russia. In this study, we aimed to analyze the genetic diversity and population structure of Livni pigs using whole-genome single nucleotide polymorphism (SNP) data. We utilized the Porcine GGP HD BeadChip on genotype samples from old (n = 32, 2004) and modern (n = 32, 2019) populations of Livni pigs. For the museum samples of Livni pigs (n = 3), we extracted DNA from their teeth, performed genomic sequencing, and obtained SNP genotypes from the whole-genome sequences. SNP genotypes of Landrace (n = 32) and Large White (n = 32) pigs were included for comparative analysis. We observed that the allelic richness of Livni pigs was higher than those of Landrace and Large White pigs (AR = 1.775-1.798 vs. 1.703 and 1.668, respectively). The effective population size estimates (NE5 = 108 for Livni pigs, NE5 = 59 for Landrace and Large White pigs) confirmed their genetic diversity tendency. This was further supported by the length and number of runs of homozygosity, as well as the genomic inbreeding coefficient (almost twofold lower in Livni pigs compared to Landrace and Large White pigs). These findings suggest that the Livni pig population exhibits higher genetic diversity and experiences lower selection pressure compared to commercial pig populations. Furthermore, both principal component and network tree analyses demonstrated a clear differentiation between Livni pigs and transboundary commercial pigs. The TreeMix results indicated gene flow from Landrace ancestors to Livni pigs (2019) and from Large White ancestors to Livni pigs (2004), which was consistent with their respective historical breeding backgrounds. The comparative analysis of museum, old, and modern Livni pigs indicated that the modern Livni pig populations have preserved their historical genomic components, suggesting their potential suitability for future design selection programs.

    青藏高原西部是青藏高原的十字路口,中亚,南亚,它是连接这些地区的潜在人类迁移途径。然而,由于缺乏覆盖该地区很长一段时间的古老基因组,因此青藏高原西部的人口历史在很大程度上仍未被探索。这里,我们报告了阿里地区65个人的全基因组数据,这些数据可追溯到现在(BP)3,500-300年。古老的青藏高原西部种群与青藏高原南部种群共享其大部分遗传成分,并且自3500BP以来一直保持遗传连续性,同时保持与青藏高原内外种群的相互作用。在青藏高原内,在1800BP之前,古代青藏高原西部的人口受到从南部向西南高原的额外扩展的影响。在青藏高原之外,至少2000年前,青藏高原西部人口与南亚和中亚人口发生了互动,和南亚相关的遗传影响,尽管非常有限,来自中亚的印度河流域文明(IVC)移民,而不是印度河流域的IVC人口。根据新的基因数据,我们的研究揭示了青藏高原内外复杂的人口相互联系。
    The western Tibetan Plateau is the crossroad between the Tibetan Plateau, Central Asia, and South Asia, and it is a potential human migration pathway connecting these regions. However, the population history of the western Tibetan Plateau remains largely unexplored due to the lack of ancient genomes covering a long-time interval from this area. Here, we reported genome-wide data of 65 individuals dated to 3,500-300 years before present (BP) in the Ngari prefecture. The ancient western Tibetan Plateau populations share the majority of their genetic components with the southern Tibetan Plateau populations and have maintained genetic continuity since 3,500 BP while maintaining interactions with populations within and outside the Tibetan Plateau. Within the Tibetan Plateau, the ancient western Tibetan Plateau populations were influenced by the additional expansion from the south to the southwest plateau before 1,800 BP. Outside the Tibetan Plateau, the western Tibetan Plateau populations interacted with both South and Central Asian populations at least 2,000 years ago, and the South Asian-related genetic influence, despite being very limited, was from the Indus Valley Civilization (IVC) migrants in Central Asia instead of the IVC populations from the Indus Valley. In light of the new genetic data, our study revealed the complex population interconnections across and within the Tibetan Plateau.

    人类Y染色体的特征是非重组和单亲遗传,携带着人类历史进化和混合的痕迹。基于先进测序技术的大规模群体特异性基因组来源彻底改变了我们对人类Y染色体多样性及其人类学和法医应用的理解。这里,我们回顾和荟萃分析了中国现代和古代人的Y染色体遗传多样性,并总结了与其起源相关的时空不同种群的创始谱系模式,扩展,和混合物。我们强调了我们确定的创始血统与与汉藏有关的语言相关的人类传播事件之间的紧密联系,阿尔泰,和与苗族有关的南方中国多种语言家庭,Tai-Kadai,南岛人,和南亚语言。随后,我们总结了法医学和人类学科学中转化应用的最新进展,包括父系生物地理祖先推断(PBGAI),姓氏调查,父系历史重建。具有末端Y染色体谱系高覆盖率的全Y测序或高分辨率面板对于捕获种族语言多样性的东亚人的基因组多样性至关重要。一般来说,我们强调了纳入更多种族语言多样性的重要性,在人类遗传研究中,现代和时空不同的古代东亚人的代表性不足,以便通过详细的时间序列全面了解东亚人的父系遗传景观,并在PBGAI中重建参考数据库,甚至包括端粒到端粒(T2T)的新技术创新,以发现新的遗传变异。
    Human Y-chromosomes are characterized by nonrecombination and uniparental inheritance, carrying traces of human history evolution and admixture. Large-scale population-specific genomic sources based on advanced sequencing technologies have revolutionized our understanding of human Y chromosome diversity and its anthropological and forensic applications. Here, we reviewed and meta-analyzed the Y chromosome genetic diversity of modern and ancient people from China and summarized the patterns of founding lineages of spatiotemporally different populations associated with their origin, expansion, and admixture. We emphasized the strong association between our identified founding lineages and language-related human dispersal events correlated with the Sino-Tibetan, Altaic, and southern Chinese multiple-language families related to the Hmong-Mien, Tai-Kadai, Austronesian, and Austro-Asiatic languages. We subsequently summarize the recent advances in translational applications in forensic and anthropological science, including paternal biogeographical ancestry inference (PBGAI), surname investigation, and paternal history reconstruction. Whole-Y sequencing or high-resolution panels with high coverage of terminal Y chromosome lineages are essential for capturing the genomic diversity of ethnolinguistically diverse East Asians. Generally, we emphasized the importance of including more ethnolinguistically diverse, underrepresented modern and spatiotemporally different ancient East Asians in human genetic research for a comprehensive understanding of the paternal genetic landscape of East Asians with a detailed time series and for the reconstruction of a reference database in the PBGAI, even including new technology innovations of Telomere-to-Telomere (T2T) for new genetic variation discovery.

    现存的旧世界骆驼(骆驼属)几千年来为东西方之间的经济和文化交流做出了贡献。1,2尽管出土了许多遗骸,3,4,5我们既不知道在现存的骆驼物种2,6,7之间观察到的普遍杂交是否也发生在已灭绝的谱系和现存的骆驼物种的祖先之间,也不知道为什么某些种群灭绝而另一些种群幸存下来。为了调查这些问题,我们从已灭绝的双峰骆驼物种中获得了古基因组和稳定同位素数据,CamelusKnoblochi.我们发现在线粒体系统发育中,所有C.knoblochi都形成了一个共生的群体,在现代的多样性中筑巢,野生双峰骆驼(Camelusferus)。相比之下,在核水平上,它们与野生和驯化的(Camelusbactrianus)双峰骆驼明显不同。此外,三种骆驼的发散模式近似为三分叉,因为最常见的拓扑仅比其他两种可能的拓扑稍微频繁一些。这种mito核系统发育不一致可能是由于所有三个物种之间的种间基因流动引起的,表明种间杂交并非现代骆驼独有,而是在骆驼属的进化史上反复出现的现象。这些结果表明,当仅考虑来自现代物种的数据时,旧世界骆驼进化史的基因组复杂性被低估了。最后,我们发现C.knoblochi种群在最后一次冰川最大值之前开始下降,通过整合古生态证据和稳定同位素数据,这可能是由于未能适应不断变化的环境。
    Extant Old World camels (genus Camelus) contributed to the economic and cultural exchanges between the East and West for thousands of years.1,2 Although many remains have been unearthed,3,4,5 we know neither whether the prevalent hybridization observed between extant Camelus species2,6,7 also occurred between extinct lineages and the ancestors of extant Camelus species nor why some populations became extinct while others survived. To investigate these questions, we generated paleogenomic and stable isotope data from an extinct two-humped camel species, Camelus knoblochi. We find that in the mitochondrial phylogeny, all C. knoblochi form a paraphyletic group that nests within the diversity of modern, wild two-humped camels (Camelus ferus). In contrast, they are clearly distinguished from both wild and domesticated (Camelus bactrianus) two-humped camels on the nuclear level. Moreover, the divergence pattern of the three camel species approximates a trifurcation, because the most common topology is only slightly more frequent than the two other possible topologies. This mito-nuclear phylogenetic discordance likely arose due to interspecific gene flow between all three species, suggesting that interspecific hybridization is not exclusive to modern camels but a recurrent phenomenon throughout the evolutionary history of the genus Camelus. These results suggest that the genomic complexity of Old World camels\' evolutionary history is underestimated when considering data from only modern species. Finally, we find that C. knoblochi populations began declining prior to the last glacial maximum and, by integrating palaeoecological evidence and stable isotope data, suggest that this was likely due to failure to adapt to a changing environment.

    武帝(,仙卑领导的北周武帝),名为YuwenYong(,543-578CE),是一位极有影响力的皇帝,他改革了地区军队制度,安抚了土耳其人,统一了这个国家的北部。他的遗传特征和身体特征,包括他的外貌和潜在的疾病,引起了学术界和公众的极大兴趣。在这项研究中,我们已经成功地产生了一个0.343×覆盖的Wudi基因组,在1240k面板上具有1,011,419个单核苷酸多态性(SNP)。通过分析与色素沉着相关的单核苷酸多态性,并进行基于头颅CT的面部重建,我们已经确定武帝具有典型的东亚或东北亚外观。此外,致病性SNP表明无地面临着对某些疾病的易感性增加,如中风。Wudi与古代契丹和黑水漠河样本以及现代达斡尔族和蒙古族有着最紧密的遗传关系,但也与黄河(YR)农民表现出额外的亲和力。我们估计,Wudi的祖先中有61%来自古代东北亚人(ANA),近三分之一来自与YR农民相关的群体。这可能归因于鲜卑王室之间的持续通婚,和当地的汉族贵族。1,2此外,我们的研究揭示了不同地区可用的古代鲜卑个体之间的遗传多样性,这表明鲜卑的形成是一个受周围种群混合影响的动态过程。
    Emperor Wu (, Wudi) of the Xianbei-led Northern Zhou dynasty, named Yuwen Yong (, 543-578 CE), was a highly influential emperor who reformed the system of regional troops, pacified the Turks, and unified the northern part of the country. His genetic profile and physical characteristics, including his appearance and potential diseases, have garnered significant interest from the academic community and the public. In this study, we have successfully generated a 0.343×-coverage genome of Wudi with 1,011,419 single-nucleotide polymorphisms (SNPs) on the 1240k panel. By analyzing pigmentation-relevant SNPs and conducting cranial CT-based facial reconstruction, we have determined that Wudi possessed a typical East or Northeast Asian appearance. Furthermore, pathogenic SNPs suggest Wudi faced an increased susceptibility to certain diseases, such as stroke. Wudi shared the closest genetic relationship with ancient Khitan and Heishui Mohe samples and modern Daur and Mongolian populations but also showed additional affinity with Yellow River (YR) farmers. We estimated that Wudi derived 61% of his ancestry from ancient Northeast Asians (ANAs) and nearly one-third from YR farmer-related groups. This can likely be attributed to continuous intermarriage between Xianbei royal families, and local Han aristocrats.1,2 Furthermore, our study has revealed genetic diversities among available ancient Xianbei individuals from different regions, suggesting that the formation of the Xianbei was a dynamic process influenced by admixture with surrounding populations.
