Recent advances have provided a wealth of molecular data with which to build phylogenies and study evolutionary processes. Morphology, however, remains fundamental for reconstructing how organisms have changed and evolved through time. Indeed, it is usually the only kind of data yielded by fossils. However, a large gap exists between genomic and phenomic data limiting our ability to use either to evaluate evolutionary hypotheses. For example, which aspects of morphology are in accordance with molecular data and can be used to reliably reconstruct major evolutionary events? Do genetic innovations such as gene and genome duplication events match morphological innovation, integration or radiation? This project aims to address these outstanding questions by collating and integrating genetic, morphological, and morphometric datasets from across the tree of life. The combined datasets will not only provide a tool kit with which to better reconstruct morphological phylogenies but also to better evaluate the nature and tempo of evolutionary processes.

最近的进展提供了丰富的分子数据，用于建立系统发生和研究进化过程。然而，形态学仍然是重建生物体如何随时间变化和进化的基础。事实上，这通常是化石提供的唯一一种数据。然而，基因组和表型数据之间存在巨大差距，限制了我们使用这两种数据来评估进化假设的能力。例如，形态学的哪些方面与分子数据一致，可以用来可靠地重建主要的进化事件？基因和基因组复制事件等遗传创新是否与形态创新、整合或辐射相匹配？该项目旨在通过整理和整合来自整个生命之树的遗传、形态和形态测量数据集来解决这些悬而未决的问题。合并后的数据集不仅提供了一个工具集，可以更好地重建形态系统发生，而且可以更好地评估进化过程的性质和速度。
