通过化石记录的透镜,被子植物的多样化促成了白垩纪的陆地革命(KTR),在这场革命中,传粉者、食草动物和捕食者经历了爆炸性的共同多样化。分子测年研究表明,早期被子植物的进化没有记录在化石记录中。这种不匹配仍然存在争议。我们使用贝叶斯分子测年方法分析了来自644个分类群和52个化石校准的83个基因的数据集,以探索化石记录、分子钟模型、数据划分等因素的不同解释对被子植物分歧时间估计的影响。控制不同来源的不确定性表明,被子植物多样化的时间尺度比以前的分子测年研究所建议的要不确定得多。分子时钟与被子植物多样性的纯粹基于化石的解释之间的不一致可能是双方错误精确的结果。我们拒绝被子植物的后侏罗纪起源,支持被子植物早期历史神秘的概念,但这一历史可能多达1.21亿年,或少至2300万年。这些结论仍然与古植物学证据和一个更一般的KTR兼容,其中主要的被子植物类群在白垩纪后期分化,同时传粉者,食草动物及其捕食者的多样化。
Through the lens of the fossil record, angiosperm diversification precipitated a Cretaceous Terrestrial Revolution (KTR) in which pollinators, herbivores and predators underwent explosive co‐diversification. Molecular dating studies imply that early angiosperm evolution is not documented in the fossil record. This mismatch remains controversial. We used a Bayesian molecular dating method to analyse a dataset of 83 genes from 644 taxa and 52 fossil calibrations to explore the effect of different interpretations of the fossil record, molecular clock models, data partitioning, among other factors, on angiosperm divergence time estimation. Controlling for different sources of uncertainty indicates that the timescale of angiosperm diversification is much less certain than previous molecular dating studies have suggested. Discord between molecular clock and purely fossil‐based interpretations of angiosperm diversification may be a consequence of false precision on both sides. We reject a post‐Jurassic origin of angiosperms, supporting the notion of a cryptic early history of angiosperms, but this history may be as much as 121 Myr, or as little as 23 Myr. These conclusions remain compatible with palaeobotanical evidence and a more general KTR in which major groups of angiosperms diverged later within the Cretaceous, alongside the diversification of pollinators, herbivores and their predators.
