There are over 10,000 species of birds and they are found in nearly every terrestrial environment. This remarkable diversity has served as a critical component of enhancing public engagement with science and nature, as evidenced by the multi-billion dollar output generated by bird-watching activities in the US economy. Birds exhibit complex behaviors, elaborate physical characteristics, and impressive adaptations, which has made them a major focus of modern scientific research. In current research, birds are a model system for comparative studies on a range of fundamental topics in biology. However, the missing piece of this otherwise powerful comparative biology toolkit is an accurate and complete description of the evolutionary relationships (phylogeny) among all bird species, i.e., an avian tree of life. This project will collect DNA data to fill this gap by producing a complete tree of life for all bird species in order to test hypotheses regarding the origins, diversification, and dispersal of birds around the planet. A complete tree will be transformative to fields like ornithology and evolutionary biology. This project will help prepare the next-generation of biodiversity scientists by training undergraduate, graduate, and post-doctoral scientists, and also will include numerous public outreach components including exhibits and videos. Developing learning modules and working with teachers will help bring the research into the classroom, reaching a diversity of students in several states. Finally, the researchers will make all data collected from each bird immediately available to the scientific community and the public to enable broad-scale comparative analyses and integration with other avian data sets."Big trees" - comprehensive species-level phylogenies - are revolutionizing the field of evolutionary biology. This project will generate genome-wide markers for 8,000 species of birds and leverage data products from other NSF-supported studies to produce a phylogenetic hypothesis for all 10,560 bird species. A well-resolved, complete, time-calibrated, species-level phylogeny of birds will allow numerous challenging hypotheses to be tested, provide the conceptual foundation for a phylogenetic revision of bird taxonomy, and permit transformative analyses aimed at elucidating the processes that generate biological diversity. Specific hypotheses to be tested using phylogenies generated by this project include 1) Neoaves underwent a rapid radiation after the K-Pg mass extinction, 2) avian diversification has been shaped by the history of intercontinental dispersal, and 3) species tree methods outperform concatenation in phylogenetic analyses of genome-scale data.

有超过10,000种鸟类，几乎在每个陆地环境中都发现它们。这种非凡的多样性是增强公众参与科学和自然的关键组成部分，这是由美国经济中观鸟活动产生的数十亿美元产出所证明的。鸟类表现出复杂的行为，精致的身体特征和令人印象深刻的适应，这使它们成为现代科学研究的主要重点。在当前的研究中，鸟类是一个模型系统，用于针对生物学的一系列基本主题进行比较研究。但是，这种原本功能强大的比较生物学工具包的缺失是对所有鸟类（即鸟类生命之树）中进化关系（系统发育）的准确而完整的描述。该项目将通过为所有鸟类物种产生一棵完整的生命树来收集DNA数据以填补这一空白，以便测试有关地球周围鸟类的起源，多样化和分散的假设。一棵完整的树将转化为诸如鸟类学和进化生物学之类的领域。该项目将通过培训本科，研究生和博士后科学家来帮助准备生物多样性科学家的下一代，还将包括许多公共宣传组件，包括展览和视频。开发学习模块并与教师合作将有助于将研究带入课堂，并在几个州吸引多样化的学生。 最后，研究人员将从立即向科学界和公众使用的每只鸟收集的所有数据，以实现广泛的比较分析并与其他鸟类数据集进行整合。“大树” - 综合物种水平的系统发育 - 正在革新进化生物学领域。该项目将为8,000种鸟类生成全基因组标记，并利用其他NSF支持研究的数据产品，以为所有10,560种鸟类种类产生系统发育假设。鸟类的良好分辨，完整，时间校准的，物种水平的系统发育将允许测试许多具有挑战性的假设，为鸟类分类法的系统发育修订提供概念基础，并允许旨在阐明产生生物学多样性的过程的变革性分析。使用该项目产生的系统发育进行测试的特定假设包括1）在K-PG质量灭绝之后，新自动腔接受了快速辐射，2）2）鸟类多样化已被跨大陆分散史和3）物种树方法在基因质量数据的系统基础中均优于串联串联。
