The order Zingiberales is a diverse group of economically and ecologically important tropical plants including banana, gingers, bird-of-paradise, and canna. This project examines the genetic, morphological, and ecological evolution of Zingiberales over geologic time scales. Morphological data from living and fossil species will be combined with DNA data to reconstruct evolutionary relationships among species and the timing of important evolutionary events. The geographical distribution of living and fossil species and changes in their ecology through time will then be examined to understand how these plants have adapted to different regions and climates through time. The integration of multiple lines of evidence from fossil and modern data is needed in order to understand evolutionary drivers and responses, current and historic biodiversity, and how modern ecosystems have been formed; all of which give us insight to the current patterns of biodiversity and the ability to predict future evolutionary patterns and ecosystem processes. The Zingiberales serve as a model for this type of study due to their ecological importance today and the presence of an extensive fossil record. In addition, because they are tropical and subtropical plants, they will help us understand the biology of a warming world.

Zingiberales订单是一组经济和生态上重要的热带植物，包括香蕉，金黄色，天生鸟和Canna。该项目研究了Zingiberales在地质时间尺度上的遗传，形态和生态演化。来自生物和化石物种的形态数据将与DNA数据结合使用，以重建物种之间的进化关系和重要的进化事件的时间。然后，将检查生物和化石物种的地理分布以及其生态变化，然后检查其生态分布，以了解这些植物如何适应不同地区和随着时间的流逝。为了了解进化驱动力和反应，当前和历史的生物多样性以及如何形成现代生态系统，需要从化石和现代数据中的多种证据整合；所有这些都使我们深入了解当前的生物多样性模式以及预测未来进化模式和生态系统过程的能力。 Zingiberales由于今天的生态重要性和广泛的化石记录而成为此类研究的模型。此外，由于它们是热带和亚热带植物，因此它们将帮助我们了解温暖世界的生物学。
