使用系统发育的方法来测试假设在大规模上，在物种采样和相关的物种特征和发生数据方面，并做到这一点与严谨，尽管所有随之而来的挑战是至关重要的，以解决许多广泛的问题，在进化和生态。然而，这种方法的应用经验系统的阻碍挥之不去的一系列理论和实践的瓶颈。该社区仍在努力应对如何开发物种水平的挑战，全面抽样的遗传学和相关的地理和表型资源，使全球范围的分析。我们说明了困难和机遇，使用玫瑰状花序作为案例研究，认为组装生物多样性数据，是规模适当的，因此全面和全球范围内，需要测试全球规模的假设。综合全面的生物多样性数据集的分支，如蔷薇科植物将是关键，以了解起源和当今的进化和生态动态的被子植物。
Using phylogenetic approaches to test hypotheses on a large scale, in terms of both species sampling and associated species traits and occurrence data-and doing this with rigor despite all the attendant challenges-is critical for addressing many broad questions in evolution and ecology. However, application of such approaches to empirical systems is hampered by a lingering series of theoretical and practical bottlenecks. The community is still wrestling with the challenges of how to develop species-level, comprehensively sampled phylogenies and associated geographic and phenotypic resources that enable global-scale analyses. We illustrate difficulties and opportunities using the rosids as a case study, arguing that assembly of biodiversity data that is scale-appropriate-and therefore comprehensive and global in scope-is required to test global-scale hypotheses. Synthesizing comprehensive biodiversity data sets in clades such as the rosids will be key to understanding the origin and present-day evolutionary and ecological dynamics of the angiosperms.
