The vinegar fly Drosophila melanogaster is a pivotal model for invertebrate development, genetics, physiology, neuroscience, and disease. The whole family Drosophilidae, which contains over 4,400 species, offers a plethora of cases for comparative and evolutionary studies. Despite a long history of phylogenetic inference, many relationships remain unresolved among the genera, subgenera, and species groups in the Drosophilidae. To clarify these relationships, we first developed a set of new genomic markers and assembled a multilocus data set of 17 genes from 704 species of Drosophilidae. We then inferred a species tree with highly supported groups for this family. Additionally, we were able to determine the phylogenetic position of some previously unplaced species. These results establish a new framework for investigating the evolution of traits in fruit flies, as well as valuable resources for systematics.

DrosoPhyla：果蝇系统发育和系统学资源


醋蝇果蝇是无脊椎动物发育、遗传学、生理学、神经科学和疾病的关键模型。整个果蝇科包含 4,400 多个物种，为比较和进化研究提供了大量案例。尽管系统发育推断有着悠久的历史，但果蝇科属、亚属和种群之间的许多关系仍未解决。为了阐明这些关系，我们首先开发了一组新的基因组标记，并组装了来自 704 个果蝇科物种的 17 个基因的多位点数据集。然后我们推断出一个物种树，其中包含该科得到高度支持的群体。此外，我们还能够确定一些以前未定位的物种的系统发育位置。这些结果为研究果蝇性状的进化建立了一个新的框架，并为系统学提供了宝贵的资源。
