Since the discovery of the <i>homeobox</i> gene in 1984, the genetic mechanisms of morphogenesis in multiple model organisms have been systematically studied. In contrast, non-model organisms are rich in complex evolutionary traits, yet their underlying genetic mechanisms have not yet been fully elucidated, so more relevant studies are still needed. Among non-model organisms, butterflies are rich in species diversity, with more than 18,700 species. In particular, butterfly wings have simple flat structures but exhibit diverse and complex patterns, likely associated with complex functions(e.g., defense and courtship) and subject to strong selective pressures, which makes them a classic system for evolutionary developmental biology studies. Early comparative morphological studies proposed the Nymphalid ground plan, providing a theoretical framework for the evolutionary developmental biology of butterfly wing patterns; a series of interference experiments on butterfly wing discs later confirmed the association between the wing developmental process and phenotypes. In recent years, by integrating genetics, developmental biology, and genomics research methods, genetic toolkit genes and loci involved in wing pattern regulation have been identified in several butterfly species, further improving the theoretical framework for studying butterfly wing pattern evolution and development. From the methodological perspective, experimental methods such as <i>in situ</i> hybridization and gene editing have played an important role in evolutionary developmental biology studies of butterfly wings, and the development of hybridization chain reaction technology and CRISPR/Cas9 gene editing technology has further advanced the feasibility of functional validation in butterflies. In the future, the development and optimization of lepidopteran RNA interference and gene editing technologies can promote functional studies, thus expanding the research systems of evolutionary developmental biology by comparing and analyzing complex traits. The above research can also be broadened to an ecological-evolutionary-developmental context to explore genetic and environmental factors that shape complex phenotypes(e.g., butterfly wing patterns), thereby deepening the understanding of key scientific issues such as the origin and evolution of biodiversity.</p>","PeriodicalId":35536,"journal":{"name":"遗传","volume":"47 2","pages":"258-270"},"PeriodicalIF":0.0,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143383486","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Since 2017, large-scale studies of ancient human genomes in East Asia, particularly in China, have emerged, resulting in a wealth of ancient genomic data from various time periods and locations, which has provided new insights into the genetic history of East Asian populations over tens of thousands of years. Especially since 2022, there emerged a series of new research progresses in the genetic histories of the northern and southern Chinese populations within the past 10,000 years. However, there is currently no systematic review focused on these recent ancient genomic studies in East Asia. Therefore, this article emphasizes the study of ancient human genomes in China and systematically reviews the genetic patterns and migration history of populations in East Asia since the Late Paleolithic. Existing research indicates that by at least 19,000 years ago, there was a north-south differentiation among ancient East Asian populations, leading to different genetic lineages divided by the Qinling-Huaihe line. Gene flow and interactions between northern and southern East Asians began in the Early Neolithic and were further strengthened from the Mid-Neolithic. By the historical period, northern East Asian ancestry played a profound role in the genetic components of southern populations, shaping the genetic structure of present-day Chinese populations. Throughout this process, ancient populations in northern and southern China also engaged in extensive interactions through coastal and inland routes with populations from surrounding regions, including Siberia, Japan, Korea, Southeast Asia, and Pacific islands, playing a crucial role in the formation of different linguistic groups. These studies have charted the evolutionary and interaction history of East Asian populations over tens of thousands of years; yet, many unresolved mysteries remain.

First, the uplift of the Qinghai-Tibet Plateau forms a geographic barrier and promotes interspecific and intraspecific genetic differentiation. Second, the uplift of the Qinghai-Tibet Plateau has provided new ecological niches for many endemic birds and facilitated their speciation. Third, the emigration and immigration of bird species between the Qinghai-Tibet Plateau and adjacent zoological regions have promoted species divergence, colonization and dispersal. Furthermore, Pleistocene glaciations and associated climate change drive postglacial colonization and lead to secondary contact, which influenced the genetic divergence of the conspecific populations and sister species. The multi-omics approach has increasingly been used in the studies on the ecological adaptive evolution of birds in Qinghai-Tibet Plateau. Future studies should focus on the role of geological and climatic factors in species differentiation, develop integrative approach with multi-omics methods, and explore the ecological mechanisms of high-elevation adaptation of plateau species.
