This project will use multiple genes to produce a well-resolved evolutionary tree for the avian order Galliformes, which includes the two most economically important birds (the chicken and turkey), some of the most spectacular and recognizable birds (such as peafowl and pheasants), and some of the most important avian model systems (e.g., the chicken and Japanese quail). This order also includes some of the most commonly hunted birds, many of which have been the focus of management studies. Hunting, combined with other factors such as habitat loss, has led to population declines, and many of these species are now of conservation concern. Evolutionary relationships in this group are poorly resolved, which has limited the ability to put the extensive information about galliform species into a comparative framework and hindered decisions regarding conservation priorities. In addition to producing a well-resolved phylogeny of the Galliformes, the collection of large numbers of loci for many species will allow us to explore several other issues, including several rapid radiations at different evolutionary depths and the impact of factors that can cause discordance between individual genes and the species history. The data generated from this project will also be used to develop classroom exercises for undergraduate courses in genetics and evolution, allowing large numbers of students to conduct research in the classroom. This will facilitate our efforts to improve science pedagogy and allow students to contribute to cutting-edge evolutionary research. The data from this study will be made broadly available through public databases and our own websites for other researchers to use.

该项目将使用多个基因为鸡形目鸟类生成一个清晰的进化树，其中包括两种最具经济意义的鸟类（鸡和火鸡），一些最壮观和可识别的鸟类（如孔雀和野鸡），以及一些最重要的鸟类模型系统（例如，鸡和日本鹌鹑）。该目还包括一些最常被猎杀的鸟类，其中许多一直是管理研究的重点。狩猎，加上其他因素，如栖息地丧失，导致人口下降，其中许多物种现在是保护问题。进化关系在这组解决得很差，这限制了能力，把广泛的信息鸡形物种到一个比较框架，并阻碍了有关保护优先事项的决定。除了产生一个很好解决的鸡形目的基因组发生，许多物种的大量基因座的收集将使我们能够探索其他几个问题，包括几个快速辐射在不同的进化深度和影响的因素，可能会导致个体基因和物种历史之间的不一致。该项目产生的数据还将用于开发遗传学和进化本科课程的课堂练习，使大量学生能够在课堂上进行研究。这将有助于我们努力改善科学教学法，并让学生为尖端的进化研究做出贡献。本研究的数据将通过公共数据库和我们自己的网站广泛提供，供其他研究人员使用。
