Typified by obligate group living and reproductive division of labor, eusocial behavior is considered the apex of animal social organization. Within a eusocial colony, a single or subset of individuals (queens) perform all reproductive duties while others (workers) forgo their own reproduction and undertake tasks related to brood care, nest maintenance, or resource acquisition. This profound and ecologically impactful behavioral transition has arisen at least 19 times in animals. Remarkably, nearly one fourth of known evolutionary origins of eusociality have occurred within a genus of sponge-dwelling snapping shrimps called Synalpheus. However, why and how eusociality evolved in these aquatic animals remains unclear and the answers to these questions may reveal potential universal requirements or consequences relating to advanced social complexity. This project seeks to reconstruct the evolutionary relationships between species in this genus to identify morphological and genomic changes that are associated with the transitions to advanced sociality. The project will generate open access resources that will be used to test potentially universal “laws” related to social evolution across animal lineages. The project will also support numerous research opportunities for undergraduate students as well as educational content for K-12 schools and web-based channels.The project will generate genomic and phenotypic data spanning about 130 species of Synalpheus snapping shrimps worldwide. These data will be used to 1) reconstruct a dated phylogeny of Synalpheus taxa using phylogenomic methods; 2) evaluate the relationship between eusociality and molecular evolution; and 3) recover morphological preadaptations and consequences of eusociality. Genomic data will be sequenced through targeted enrichment of previously published and newly developed probe sets. Morphological data will be generated through traditional microscopy and X-ray based micro-CT-scanning of closely related species spanning different social organizations. Both genomic and phenotypic data will be analyzed using phylogenetic comparative methods enabled with initial phylogenetic products. Project activities will identify patterns of molecular evolution between eusocial and non-eusocial species to test hypotheses suggesting that social organization affects rates of molecular evolution via demographic effects such as reduced effective population sizes and increased generation time. Through 3D morphometric analyses, the project will work to uncover morphological preadaptations to eusocial origins, impacts of social behavior on morphological evolution, and putatively contingent or deterministic pathways toward convergent phenotypic syndromes.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.

以专业的群体生活和生殖分工为代表的，Eusocial行为被认为是动物社会组织的顶点。在一个社会群落中，一个或子集（皇后区）执行所有生殖职责，而其他人（工人）忘记了自己的复制品，并承担与育雏，巢穴维护或资源获取有关的任务。这种深刻和生态影响的行为过渡至少在动物中产生了19次。值得注意的是，在称为Synalpheus的赞助商扣虾属的属中发生了几乎四分之一已知的Eusociality进化起源。但是，为什么以及如何以及如何在这些水生动物中演变的欧洲社会性尚不清楚，这些问题的答案可能会揭示与先进的社会复杂性有关的潜在普遍要求或后果。该项目旨在重建该属中物种之间的进化关系，以确定与先进社会性过渡相关的形态和基因组变化。该项目将生成开放式访问资源，该资源将用于测试与跨动物的社会进化有关的潜在通用“法律”。该项目还将为本科生以及K-12学校和基于Web的渠道的教育内容提供众多研究机会。该项目将生成大约130种全球Synalpheus snapting Shrimps的基因组和表型数据。这些数据将用于1）使用系统发育方法重建过时的Synalpheus税的系统发育； 2）评估欧洲社会性与分子进化之间的关系； 3）恢复界面性的形态前序和后果。基因组数据将通过对先前发表的探针集的靶向富集进行测序。形态学数据将通过传统的显微镜和基于X射线的微分离扫描，这些物种跨越不同的社会组织。基因组和表型数据将使用最初的系统发育产物实现的系统发育比较方法进行分析。项目活动将确定界面和非共同社会物种之间分子进化的模式，以检验假设，这表明社会组织会通过人口统计学效应（例如减少有效的人口规模和增加的生成时间）影响分子进化的速度。通过3D形态计量学分析，该项目将致力于揭示对界面起源的形态学序列，社会行为对形态学进化的影响以及推定的偶然性或确定性途径促成融合表型综合综合症。该奖项颁发奖项，反映了NSF的法定任务，并通过评估了Intelligia cr Intelligial and Intellitial and Inthernitial and Inthernitial的支持。
