Rapid evolutionary radiations allow tremendous insights into speciation and biogeographic history. However, reconstruction of evolutionary relationships in such radiations has often been challenging owing largely to short periods of time between lineage-splitting events. Preliminary simulations show that using DNA sequence data from hundreds of gene regions helps improve estimates of genealogical relationships between species in rapid radiations. This study aims to resolve relationships within the bird family Zosteropidae, a group characterized by the fastest speciation rate known among land vertebrates. Investigators will use next generation sequencing technology to collect DNA sequence data from hundreds of genomic regions to illuminate evolutionary relationships among members of the family.Resolution of genealogic relationships within Zosteropidae is vital to opening novel research avenues in historical biogeography across several archipelagos in the Old World. More broadly, this research can provide methodological insights into paths toward resolving relationships in other rapid evolutionary radiations. This study provides an excellent training opportunity for undergraduate students supported by KU?s Office of Diversity in Science Training. Through this project the investigators will help prepare undergraduates from underrepresented groups for careers in science through mentoring in collecting and analyzing data, as well as in presenting and publishing research.

快速进化辐射使我们能够深入了解物种形成和生物地理历史。 然而，在这种辐射中重建进化关系往往具有挑战性，这主要是由于谱系分裂事件之间的时间间隔很短。 初步模拟表明，使用来自数百个基因区域的 DNA 序列数据有助于改进对快速辐射中物种之间谱系关系的估计。 这项研究旨在解决鸟类科Zosteropidae内部的关系，该科的特点是已知陆地脊椎动物中物种形​​成速度最快。 研究人员将使用下一代测序技术从数百个基因组区域收集 DNA 序列数据，以阐明该家族成员之间的进化关系。解决 Zosteropidae 内部的谱系关系对于在旧世界几个群岛的历史生物地理学中开辟新的研究途径至关​​重要。 更广泛地说，这项研究可以为解决其他快速进化辐射中的关系提供方法论见解。 这项研究为堪萨斯大学科学培训多样性办公室支持的本科生提供了绝佳的培训机会。 通过这个项目，研究人员将通过指导收集和分析数据以及展示和发表研究成果，帮助弱势群体的本科生为科学职业做好准备。
