9873705 Chiappe The early history of birds, the most diverse group of extant land vertebrates, has long been a matter of intense scientific scrutiny. Until recently, scientists have had to rely on the scant fossil evidence available from just a few known species of the Mesozoic Era to draw conclusions about the historical relationships of early birds. Lately, however, the situation has changed dramatically with the discovery of many new Mesozoic bird species. A wealth of new evidence is now available for analysis and interpretation. This project will include a comprehensive genealogical study of all available species of early birds. It will include anatomical studies of species including some as yet undescribed, and build upon existing genealogical analyses of early birds. The work will yield new hypotheses of relationships for all species of early birds (approximately 40 so far known).

9873705 Chiappe鸟类是现存陆地脊椎动物中最具多样性的一组，其早期历史长期以来一直是一个严格的科学审查问题。 直到最近，科学家们还不得不依靠从中生代少数已知物种中获得的少量化石证据来得出有关早期鸟类历史关系的结论。 然而，最近随着许多新的中生代鸟类的发现，情况发生了巨大的变化。 现在有大量新证据可供分析和解释。 该项目将包括对所有现有的早期鸟类物种进行全面的谱系研究。 它将包括物种的解剖学研究，包括一些尚未描述的物种，并建立在现有的早期鸟类谱系分析的基础上。这项工作将为所有早期鸟类（迄今已知约40种）的关系提出新的假设。
