Dr. Joel Cracraft and Kathleen Helm-Bychowski, at the University of Illinois, Chicago are studying the evolutionary relationships of the Australasian birds-of-paradise (Paradisaeidae) to other families of Australasian songbirds. Phylogenetic relationships are assessed by comparisons of mitochondrial DNA sequences between species. The phylogeny is determined by computer analysis, and will be compared with a phylogeny based on anatomical data. The study will provide important evidence about the origin and evolutionary history of the birds-of-paradise, and help us to understand the diversification of the Australasian birds. The phylogenetic study will also help us understand the structure and function of the mitochondrial genes and how they are modified by evolution.

芝加哥伊利诺伊大学的Joel craft博士和Kathleen Helm-Bychowski博士正在研究澳大拉西亚天堂鸟（Paradisaeidae）与澳大拉西亚其他鸣禽家族的进化关系。系统发育关系是通过比较物种之间的线粒体DNA序列来评估的。系统发育由计算机分析确定，并将与基于解剖数据的系统发育进行比较。这项研究将为研究天堂鸟的起源和进化历史提供重要的证据，并有助于我们了解澳大利亚鸟类的多样性。系统发育研究也将帮助我们了解线粒体基因的结构和功能，以及它们是如何通过进化而被修改的。
