Collaborative Research: Paleozoic echinoderms as model systems for the study of evolutionary modes Unraveling the drivers of evolution in the fossil record is critical for understanding how organisms occupy new morphologic, ecologic, and geographic spaces. This information, gleaned from the geologic past across climate perturbations, is vital for understanding and predicting how evolution will operate across the biodiversity and climate crises today. The research team will focus on groups of ancient echinoderms, marine invertebrates (e.g., sea stars) that were globally widespread through Earth’s history. This group is vastly understudied and, as such, analyses conducted on the group will provide critical insight into animal response to Earth systems perturbations. New organismal forms appear through shifts in developmental timing, called heterochrony. What is unclear is how shifts in climate, organism biogeography, and ecology affect heterochronic shifts. This research uses a holistic approach via multiple analyses, addressing changes in ecology, biogeography, and heterochrony through extreme climate events that occurred hundreds of millions of years ago, to explore aspects of organisms’ evolutionary history and long-term consequences.Database, museum, and literature data will be used jointly within phylogenetic frameworks to develop understanding of the evolutionary dynamics (i.e., changes in rates of evolution, heterochrony, biogeography, ecology) of extinct echinoderms. The chief merit of this research is the integration of multiple variables within a phylogenetic context to quantitatively understand broader patterns of evolution through abiotic change on Earth. This project will train the next generation of museum curators, educators, and researchers, and provide open-access information about echinoderms. Training will be conducted through undergraduate summer workshops on museum research techniques. Open access information about the echinoderm clades studied in this project will be published on the Digital Atlas of Ancient Life’s paleontology open access textbook. Echinoderm resources, created through this project and from previous works, will be collated on a WikiProject into one central hub for current and future echinoderm paleobiology researchers.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

协作研究：古生​​代棘皮动物作为研究模式的模型系统，用于研究化石记录中进化的驱动因素对于理解生物如何占据新的形态，生态和地理空间至关重要。这些信息是从整个气候扰动中的地质过去收集的，对于理解和预测当今生物多样性和气候危机的进化将如何运作至关重要。研究小组将专注于古老的棘皮动物，海洋无脊椎动物（例如，海星），这些群体在全球范围内广泛存在于地球历史上。该小组被广泛理解，因此，对该组进行的分析将提供对动物对地球系统扰动的反应的批判性见解。新的有机形式是通过发育时机的转移来出现的，称为杂音。尚不清楚的是气候，生物地理学和生态学的转变如何影响异缘转移。这项研究通过多次分析使用整体方法，通过发生的极端气候事件来解决生态学，生物地理学和杂音事件的变化，而极端的气候事件发生在数亿年前，以探索生物体的进化历史和长期后果的各个方面。数据库酶，博物馆，博物馆和文献数据将在类似框架中共同使用。杂物，生物地理，生态学），灭绝的棘皮动物。这项研究的主要优点是将多个变量整合在系统发育环境中，以定量地了解地球上的非生物变化，从而定量了解更广泛的进化模式。该项目将培训下一代博物馆策展人，教育者和研究人员，并提供有关棘皮动物的开放访问信息。培训将通过博物馆研究技术的夏季本科讲习班进行。有关该项目研究的棘皮动物进化枝的开放访问信息将在古代古生物学开放访问教科书的数字地图集上发布。通过该项目和以前的工作创建的棘皮动物资源将与Wikiproject合作，以作为当前和未来的Echinoderm古生物学研究人员进行一个中心枢纽。该奖项反映了NSF的法定任务，并被认为是通过基金会的智力优点和广泛的影响审查审查的审查标准来通过评估来诚实的支持。
