项目摘要

Much of the diversity of life has arisen through the process of adaptive radiation. Adaptive radiation occurs when a group rapidly diversifies into many species to fill a variety of ecological roles. While adaptive radiation is a common theme in the evolution of life, many of its features are poorly understood. This project seeks to better understand how adaptive radiation proceeds. The project will examine the rate of diversification in genes, morphology and species diversity over the evolutionary history of a group of rodents containing more than 600 species. The study will determine how changes in genes, morphology and species are correlated as the species diversified. Importantly, the group under study contains the common lab mouse and rat, two species that serve as scientific models in medical and basic research. This study will place these model organisms in an evolutionary context that will allow scientists to better understand how their genes and other characteristics have evolved. Such understanding provides new insight into genes and characteristics of medical significance. Scientific meetings organized by the researchers will bring together scientists who study mice and rats from different perspectives, including molecular biology and medicine, to share insight and generate new research questions. In addition to the broader impacts on basic science and medicine, public outreach and education events at participating natural history museums will use the results of this research to teach principles of evolutionary biology to K-12 students and improve public understanding of science.This project integrates comparative genomics with quantitative morphology in a rigorous phylogenetic framework to illuminate the dynamics of diversification in lineages, phenotypes, and genes across the most species-rich adaptive radiation in mammals. The exceptional species and ecomorphological diversity in rats and mice (subfamily Murinae, 634 living species) arose over the last 14 million years through replicate adaptive radiations, primarily in the distinct biogeographic units of Indo-Australia. This research will expand on the genomic resources from the leading mammalian model organisms to encompass the diversity of murine rodents by sequencing whole exomes from a large, phylogenetically dispersed set of species. In addition, the project will generate high-resolution, 3D morphometric models of cranial and post-cranial skeletons from the same species. The project will combine these distinct data layers to: estimate a species-level phylogeny of the Murinae; identify and date biogeographic and ecological transitions; estimate diversification rate shifts across the phylogeny; estimate rates of phenotypic and molecular evolution relative to transitions (biogeographic and ecological) and shifts in lineage diversification rate; test for correlations between the tempos of phenotypic and molecular evolution; and, quantify morphological and molecular convergence.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
许多生命的多样性都是通过适应性辐射过程产生的。适应性辐射发生在一个群体迅速分化成许多物种,以填补各种生态角色。虽然适应性辐射是生命进化中的一个共同主题,但人们对它的许多特征知之甚少。该项目旨在更好地了解适应性辐射的进展。该项目将研究一组包含600多个物种的啮齿动物在进化历史中基因、形态和物种多样性的多样化率。这项研究将确定基因,形态和物种的变化如何与物种多样化相关。重要的是,正在研究的群体包含常见的实验室小鼠和大鼠,这两个物种在医学和基础研究中作为科学模型。这项研究将把这些模式生物放在进化的背景下,使科学家能够更好地了解它们的基因和其他特征是如何进化的。这样的理解提供了对基因和具有医学意义的特征的新见解。由研究人员组织的科学会议将汇集从不同角度研究小鼠和大鼠的科学家,包括分子生物学和医学,以分享见解并产生新的研究问题。除了对基础科学和医学产生更广泛的影响外,参与自然历史博物馆的公共宣传和教育活动将利用这项研究的结果向K-12学生教授进化生物学原理,提高公众对科学的理解。该项目将比较基因组学与定量形态学结合在严格的系统发育框架中,阐明谱系,表型,和基因在哺乳动物中最丰富的物种适应性辐射。在过去的1400万年里,通过复制适应性辐射,大鼠和小鼠(鼠科亚科,634种活物种)的特殊物种和生态形态多样性出现了,主要是在印度-澳大利亚独特的地理单位。这项研究将扩大从领先的哺乳动物模式生物的基因组资源,包括鼠类啮齿动物的多样性,通过测序整个外显子组从一个大的,遗传学分散的物种。此外,该项目还将生成同一物种的颅骨和后颅骨的高分辨率3D形态测量模型。该项目将联合收割机结合这些不同的数据层,以:估计鼠科的物种水平进化;确定地理和生态过渡并确定日期;估计整个进化过程中的多样化率变化;估计相对于过渡的表型和分子进化率。(地理和生态)和谱系多样化率的变化;表型和分子进化的节奏之间的相关性测试;该奖项反映了NSF的法定使命,并通过使用基金会的知识价值和更广泛的影响审查标准进行评估,被认为值得支持。
