采蜂（Andrenidae）是一个主要的蜜蜂家族，有超过3000种，几乎遍布全球。它们是北方温带生态系统的一个特别重要的组成部分，是自然和农业环境中的重要授粉者。尽管他们的生态和进化意义，我们的知识的Andrenidae的进化历史是稀疏的，不足以表征其时空起源和系统发育关系。这限制了我们理解多样化动态的能力，导致了所有蜜蜂中物种第二丰富的属，Andrena Fabricius和北美物种最丰富的属，Perdita Smith。在这里，我们开发了一个全面的基因组数据集的195种Andrenidae，包括所有主要的血统，照亮家庭的进化历史。使用化石信息的分歧时间估计，我们表征宏观进化动力学，结合古气候信息，并提出我们的研究结果的背景下，所有其他蜜蜂部落的多样化率估计。我们发现，在过去的1500万年里，Andrenidae的多样化率急剧增加，特别是在Andrena和Perdita属。这表明，这两个群体和蜂属的育雏寄生虫（蜜蜂科），这是主要的cleptoparasitic对应的Andrena，在年龄上是相似的，代表了最快的多样化谱系的所有蜜蜂。使用我们新开发的时间框架andrenid演化，我们估计晚白垩世起源于南美洲的家庭和重建过去的扩散事件，导致其今天的分布。
The mining bees (Andrenidae) are a major bee family of over 3000 described species with a nearly global distribution. They are a particularly significant component of northern temperate ecosystems and are critical pollinators in natural and agricultural settings. Despite their ecological and evolutionary significance, our knowledge of the evolutionary history of Andrenidae is sparse and insufficient to characterize their spatiotemporal origin and phylogenetic relationships. This limits our ability to understand the diversification dynamics that led to the second most species-rich genus of all bees, Andrena Fabricius, and the most species-rich North American genus, Perdita Smith. Here, we develop a comprehensive genomic dataset of 195 species of Andrenidae, including all major lineages, to illuminate the evolutionary history of the family. Using fossil-informed divergence time estimates, we characterize macroevolutionary dynamics, incorporate paleoclimatic information, and present our findings in the context of diversification rate estimates for all other bee tribes. We found that diversification rates of Andrenidae steeply increased over the past 15 million years, particularly in the genera Andrena and Perdita. This suggests that these two groups and the brood parasites of the genus Nomada Scopoli (Apidae), which are the primary cleptoparasitic counterparts of Andrena, are similar in age and represent the fastest diversifying lineages of all bees. Using our newly developed time frame of andrenid evolution, we estimate a late Cretaceous origin in South America for the family and reconstruct the past dispersal events that led to its present-day distribution.
