This research will unravel the evolutionary history of a complex parasite-host system, specifically, ant species that are parasites of the colonies of other ant species. This parasite-host system has evolved many times across ant species, but it is unknown how this convergently evolved behavior has affected speciation patterns in the social parasites. The project uses an integrative approach that includes (i) reconstructing the speciation patterns and the evolutionary history of ant social parasites using genetic data from ant genomes; (ii) unearthing the global biodiversity of ant social parasites using new methods to biodiversity discovery to effectively delimit species and revise the classification of ant social parasites across the ant tree of life; (iii) deciphering the genetic mechanisms underlying the formation of new social parasite species. In summary, this project integrates several approaches to understand organismal evolutionary biology, exploring how parasitic lineages originate repeatedly.Understanding the origin and maintenance of biological diversity is a major goal in evolutionary biology. Speciation by evolving reproductive isolation in allopatry is well accepted. However, theoretical and empirical studies have established that reproductive isolation can evolve in sympatry, in the absence of geographical isolation. Empirical evidence for sympatric speciation has been accumulating from studies of ant inquiline social parasites. Inquiline parasites inhabit the living space of other species. The social parasites of ants are other ant species, often closely related, that are highly specialized brood parasites. The parasitic species exploit their hosts’ social organization to selfishly maximize their individual reproductive output. In contrast to other species that evolved via sympatric speciation, the diverse assemblage of ant social parasites is a promising and underutilized system for comparative study because at the moment approximately 390 ant social parasite species are known from 34 genera. The high number of independently evolved parasite species provides unique conditions for comparative research exploring the ecological circumstances and the genetic mechanisms associated with the independent evolutionary origins of ant social parasites. This project integrates research, education, and outreach, and will therefore benefit society in general. Graduate and undergraduate students will be trained in organismal evolutionary biology in both the laboratory and the field, and novel undergraduate field biology classes will be developed at Arizona State University (ASU). Collaborations with colleagues in South America and Europe will facilitate the international exchange of students and long-term enhancement of a global scientific community. The outreach program will (i) train teachers at elementary, middle, and high schools with high percentages of under-represented and disadvantaged groups in the Phoenix Metro area, (ii) integrate community colleague students into teaching and research activities at ASU, (iii) use social parasites as a tool to start a conversation about controversial or socially loaded metaphors in science, and (iv) offer student workshops to integrate social and brood parasitism research across the animal kingdom.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.

这项研究将揭示一个复杂的寄生-宿主系统的进化历史，特别是蚂蚁物种是其他蚂蚁物种殖民地的寄生虫。这种寄生-宿主系统在蚂蚁物种中已经进化了很多次，但这种趋同进化的行为如何影响社会寄生虫的物种形成模式还不清楚。该项目采用一种综合方法，包括㈠利用蚂蚁基因组的遗传数据重建蚂蚁社会寄生虫的物种形成模式和进化历史; ㈡利用生物多样性发现的新方法发掘蚂蚁社会寄生虫的全球生物多样性，以有效地界定物种，并修订蚂蚁生命树中蚂蚁社会寄生虫的分类;（iii）破解形成新的群居寄生虫物种的遗传机制。总而言之，这个项目整合了几种方法来理解生物进化生物学，探索寄生谱系是如何重复起源的。理解生物多样性的起源和维持是进化生物学的一个主要目标。物种形成的进化生殖隔离在异地是公认的。然而，理论和实证研究已经确定，生殖隔离可以在同域中进化，在没有地理隔离的情况下。同域物种形成的经验证据已经从蚂蚁群居寄生虫的研究积累。隐翅虫寄生于其他物种的生存空间。蚂蚁的社会寄生虫是其他蚂蚁物种，通常是密切相关的，是高度专业化的育雏寄生虫。寄生物种利用宿主的社会组织自私地最大化其个体生殖产出。与同域物种形成的其他物种相比，蚂蚁社会寄生虫的多样性组合是一个有前途的和未充分利用的系统进行比较研究，因为目前大约有390种蚂蚁社会寄生虫已知来自34属。大量的独立进化的寄生虫物种提供了独特的条件比较研究探索的生态环境和遗传机制与独立进化起源的蚂蚁社会寄生虫。该项目整合了研究、教育和推广，因此将造福于整个社会。研究生和本科生将在实验室和现场接受生物进化生物学培训，亚利桑那州立大学（ASU）将开发新的本科现场生物学课程。与南美和欧洲的同事合作将促进学生的国际交流和长期加强全球科学界。外展计划将（一）培训教师在小学，初中和高中与凤凰城大都会地区的代表性不足和弱势群体的比例高，（二）整合社区同事的学生到教学和研究活动在亚利桑那州立大学，（三）使用社会寄生虫作为一种工具，开始对有争议的或社会加载的隐喻在科学对话，和（iv）提供学生研讨会，以整合整个动物王国的社会和育雏寄生研究。该奖项反映了NSF的法定使命，并已被认为是值得通过使用基金会的智力价值和更广泛的影响审查标准进行评估的支持。
