A grant has been awarded to Dr. Annalisa Berta at San Diego State University tosupport a collaborative project involving museum and university scientists in the reconstruction of evolutionary relationships among fossil and living species of baleen whales. Both anatomical and molecular data sets will be employed and the results of separate and combined analyses of these data sets explored. This study will add considerable new anatomical information from fossil baleen whales (especially characters from the skull and jaws) examined in various museum collections in the US, Europe, Australasia, and Japan. This framework will then be used to interpret the development of the unique filter feeding specializations of baleen whales, especially the evolutionary transition in feeding from tooth-bearing fossil species to baleen-bearing modern species. Few studies have investigated the interrelationships of baleen whales and the results are conflicting. This study will place modern baleen whale diversity in a historical context. Study of the past diversity of baleen whales in relation to times of global climate change may suggest conservation strategies for endangered modern species that may not have otherwise been considered. This project will provide training for both undergraduate and graduate students. Results of the study will be incorporated into exhibits about whale evolution planned at the San Diego Museum of Natural History.

圣地亚哥州立大学的 Annalisa Berta 博士获得了一笔赠款，以支持博物馆和大学科学家参与的合作项目，重建须鲸化石和现存物种之间的进化关系。将采用解剖学和分子数据集，并探索这些数据集的单独和组合分析的结果。这项研究将从美国、欧洲、澳大利亚和日本各博物馆收藏的须鲸化石（尤其是头骨和下颌的特征）中添加大量新的解剖学信息。然后，该框架将用于解释须鲸独特的滤食专门化的发展，特别是从带牙齿的化石物种到带须鲸的现代物种的进化转变。很少有研究调查须鲸之间的相互关系，而且结果是相互矛盾的。这项研究将现代须鲸多样性置于历史背景中。对过去须鲸多样性与全球气候变化时期关系的研究可能会提出对濒临灭绝的现代物种的保护策略，而这些策略可能没有被考虑到。 该项目将为本科生和研究生提供培训。 研究结果将被纳入圣地亚哥自然历史博物馆计划的鲸鱼进化展览中。
