As we know from human appearance, physical variation is essential for recognizing individuals. Recognition of individual appearance in animals can have consequences for choosing a mate, and consequently the trajectory of a species' evolution, as well. On the one hand, evolution is typically believed to reduce the variation of individual appearance within a species. On the other, evolution has been shown to favor individuality when it promotes recognition. This project seeks to better understand these seemingly contrasting consequences of evolution through experiments with paper wasps, insects commonly used to study the evolution of behavior. The research will focus on a paper wasp species with highly individual facial patterns, and investigates how facial variation is encoded in its genes, how it is maintained, and to what extent natural selection favoring individuality contributes to divergence of populations to create new species. This project will also promote science education through a collaboration with the Sciencenter of Ithaca, NY and the local state park system.The proposed work will study the selective and demographic processes shaping patterns of diversity in a uniquely tractable paper wasp. The color patterns of Polistes fuscatus wasps mediate individual recognition among co-nesting queens and show dramatic variation both within and between populations. Previous work has demonstrated that the color pattern diversity in P. fuscatus is the result of selection for individuals to advertise their identity and facilitate recognition. The extreme color pattern diversity, relatively simple genetic architecture of color variation, small genome size and abundant populations make these wasps ideal for addressing fundamental questions regarding the maintenance of phenotypic and genetic diversity in recognition systems. This powerful system will be used to investigate four major topics using a combination of comparative, population and functional genomics approaches coupled with detailed phenotyping of specimens: (1) What is the genetic architecture of individual identity signals? (2) How do phenotypic diversity and genetic architecture interact to determine patterns of genetic diversity? (3) What are the roles of selective and demographic forces in shaping patterns of phenotypic diversity? (4) Does selection on recognition systems lead to the maintenance of variation or rapid turnover in diversity across time and space?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.

正如我们从人类外表中知道的那样，身体差异对于识别个体至关重要。对动物个体外观的识别可能会对选择配偶产生影响，从而影响物种的进化轨迹。 一方面，人们通常认为进化会减少物种内个体外观的变异。另一方面，进化已被证明在促进认可时有利于个性。 该项目旨在通过纸黄蜂（通常用于研究行为进化的昆虫）进行实验，更好地理解这些看似截然不同的进化后果。 该研究将重点关注具有高度个性化面部图案的纸黄蜂物种，并研究面部变异如何在其基因中编码、如何维持，以及有利于个性的自然选择在多大程度上导致种群分化以创造新物种。该项目还将通过与纽约州伊萨卡科学中心和当地州立公园系统的合作来促进科学教育。拟议的工作将研究形成独特易驯化纸黄蜂多样性模式的选择性和人口统计过程。马蜂的颜色模式介导了共筑蜂王之间的个体识别，并且在种群内部和种群之间表现出巨大的差异。先前的工作表明，P. fuscatus 的颜色图案多样性是个体选择的结果，以宣传其身份并促进识别。极端的颜色图案多样性、相对简单的颜色变化遗传结构、较小的基因组大小和丰富的种群使这些黄蜂成为解决有关识别系统中表型和遗传多样性维持的基本问题的理想选择。这个强大的系统将用于研究四个主要主题，结合比较、群体和功能基因组学方法以及详细的标本表型分析：（1）个体身份信号的遗传结构是什么？ (2)表型多样性和遗传结构如何相互作用来确定遗传多样性的模式？ (3) 选择力和人口统计力在塑造表型多样性模式中的作用是什么？ (4) 识别系统的选择是否会导致跨时间和空间的多样性的维持或快速更替？该奖项反映了 NSF 的法定使命，并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，被认为值得支持。
