摘　　要：从古DNA视角探讨古代生物的遗传组成已有40多年历史。自2005年开始,随着高通量测序技术平台的开发应用及对小片段DNA分子提取能力的加强,古DNA研究跨入全新的深时古基因组时代,不仅解决了诸多生物谱系系统学问题,丰富了包括人类在内的多种生物的迁移、演化细节,而且启动了“全基因组-大数据-多物种”尺度研究生物对气候变化的分子响应,将古DNA研究涉及的样品年代从10万年以内拓展到近200万年前的早更新世。中国科学家近几年在东亚人群遗传演化和迁徙融合方面实现了诸多有影响力的突破,填补了现代人类演化进程中的重要“缺环”。相比而言,学界对除人类之外的脊椎动物古DNA研究关注度较低。本文回顾了第四纪晚期中国大型哺乳动物古DNA研究系列进展,分别总结了相关研究在揭示古代群体与现生群体的系统演化关系、古哺乳动物基因交流、动物种群对气候变化的分子响应等方面的研究突破,并对中国哺乳动物古基因组领域面临的机遇和挑战进行了展望。It has been more than 40 years since the beginning of exploring the genetic composition of ancient organisms from the perspective of ancient DNA.In the recent 20 years,with the development and application of high-throughput sequencing technology platforms and the improved efficiency of retrieving highly fragmented DNA molecules,ancient DNA research moved forward to a brand-new era of deep-time paleogenomics.It not only solved many controversial phylogenetic problems,enriched the migration and evolution details of various organisms including humans,but also launched exploration of the molecular responses to climate changes in terms of“whole genomic-big data-multi-species”level.Moreover,it expanded the sample age from no more than 100,000 years to the Early Pleistocene,~2 million years ago.Recently,Chinese scientists have made many influential breakthroughs in evolution and migration integration of East Asian populations and thus filled an important gap in the evolutionary process of modern human.Compared to the situation in human paleogenomic studies,less attention has been paid to the study of ancient DNA from vertebrates remains.In this review,we introduce a series of advances in ancient DNA investigations of large mammals in Late Quaternary in China,summarize the research breakthroughs in revealing the systematic evolutionary relationship between ancient and extant groups,gene flow,and molecular responses of mammalian populations to climate change,and explore the opportunities and key challenges in the field of mammalian paleogenomics.
