Corbiculate蜜蜂包括四个部落，先进的真社会Apini和Meliponini，独立的真社会Bombini，和孤独或社区Euglossini。恢复四个部落的强大系统发育对于了解真社会性的进化具有相当重要的意义，但之前的形态学和分子研究得出了截然不同的结论。我们研究了由12个核基因组成的扩展数据集，以探索支持分子假设的路线。结果证实了以前的分子研究，支持增加更多的基因被添加。跨基因，支持的分子假说是正相关的信息位点的数量和相对取代率。支持分子树的系统发育信号几乎完全依赖于第一和第三密码子位置的同义变化。我们讨论了未来可能的解决令人沮丧的持续corbiculate蜜蜂争议的方法。
The corbiculate bees comprise four tribes, the advanced eusocial Apini and Meliponini, the primitively eusocial Bombini, and the solitary or communal Euglossini. Recovering a robust phylogeny for the four tribes is of considerable importance for understanding the evolution of eusociality, yet previous morphological and molecular studies reached strikingly different conclusions. We study an expanded data set consisting of 12 nuclear genes to explore lines of support for the molecular hypothesis. Results corroborate previous molecular studies; support increases as more genes are added. Across genes, support for the molecular hypothesis is positively correlated with the number of informative sites and the relative substitution rate. Phylogenetic signals supporting the molecular tree rest almost entirely upon synonymous changes at the first and third codon positions. We discuss possible future approaches for resolving the frustratingly persistent corbiculate bee controversy.
