了解哪些因素推动了一个群体的进化成功是生物学中的一个基本问题。被子植物是植物中最成功的类群，具有辐射性和适应性。在被子植物中，豆科植物是这种成功辐射和适应的一个很好的例子。我们在这里调查了过去的气候变化，地理扩张和习惯转变的相互作用如何促进了豆科植物的多样化，豆科植物中最大的分支之一。使用一个全面的属级的三个质体标记，我们估计分歧的时间，推断习惯的转变，测试系统发育和时间多样化的异质性，并重建祖先的地理范围。我们发现，菜豆类谱系经历了两次戏剧性的积累。在渐新世晚期，至少有六个木本分支迅速分化，这可能是对渐新世晚期变暖和干旱的反应，也是亚洲、非洲和澳大利亚迅速开发新生态机会的结果。物种最丰富的谱系是草本植物，从中新世早期开始迅速多样化，这可能归因于干旱气候，沿着非洲、亚洲和美洲季节性干旱的热带森林的扩张。phaseoloid组提供了一个很好的案例，支持生态机会和关键创新的相互作用推动了进化成功的观点。
Understanding which factors have driven the evolutionary success of a group is a fundamental question in biology. Angiosperms are the most successful group in plants and have radiated and adapted to various habitats. Among angiosperms, legumes are a good example for such successful radiation and adaptation. We here investigated how the interplay of past climate changes, geographical expansion and habit shifts has promoted diversification of the phaseoloid legumes, one of the largest clades in the Leguminosae. Using a comprehensive genus-level phylogeny from three plastid markers, we estimate divergence times, infer habit shifts, test the phylogenetic and temporal diversification heterogeneity, and reconstruct ancestral biogeographical ranges. We found that the phaseoloid lineages underwent twice dramatic accumulation. During the Late Oligocene, at least six woody clades rapidly diverged, perhaps in response to the Late Oligocene warming and aridity, and a result of rapidly exploiting new ecological opportunities in Asia, Africa and Australia. The most speciose lineage is herbaceous and began to rapidly diversify since the Early Miocene, which was likely ascribed to arid climates, along with the expansion of seasonally dry tropical forests in Africa, Asia, and America. The phaseoloid group provides an excellent case supporting the idea that the interplay of ecological opportunities and key innovations drives the evolutionary success.
