Many models of primate behavior and evolution have relied heavily on the generally well-studied baboon genus. However, the relatively understudied Kinda baboon exhibits unique physical and social traits compared to other baboon species, suggestion a wider variety of reproductive strategies that should be considered in baboon models. This project will collect new data on the Kinda baboon to understand the evolution of their unusual biology, facilitating future comparative studies into the evolution of mating system diversity among primates including our own hominin lineage. This project will facilitate the training of graduate and undergraduate students in multiple aspects of research including field data collection and processing, computational methods, and laboratory work. The project will support international research collaborations, science outreach to students and local communities, conservation efforts, and data dissemination through various media. Kinda are the only baboon species for which we lack detailed biological data, and are an excellent species on which to test predictions of evolutionary models in primatology. Kinda baboons have a unique suite of characteristics, including reduced sexual dimorphism and male-driven intersexual social relationships, suggesting that baboons exhibit more variation in their reproductive strategies than previously thought. This project will test the hypothesis that compared to other baboons, Kinda baboons evolved traits indicative of weaker direct, and stronger indirect, male-male competition. This project has two major objectives, to: 1) characterize the mating system and types of reproductive competition observed in a population of Kinda baboons; and 2) characterize the consequences of these characteristics for female sexual signaling. We will achieve this through: i) the characterization of female reproductive life-history; ii) hormonal assessment of reproductive profiles; iii) the calculation of female reproductive synchrony and male reproductive skew; and iv) the reliability of female sexual signals in advertising female fertility. Since data on these parameters exist for other baboon populations, we will be able to compare our results to those of other baboon taxa. This project will result in the first detailed longitudinal dataset on wild Kinda baboon reproduction, particularly in relation to physiology and sexual signaling. The project will facilitate future comparative studies into the evolution of mating system diversity among primates and other animals. Further, exploring the behavioral and life-history correlates of reduced sexual dimorphism, a characteristic observed in Kinda baboons and also in hominins, will provide important insights into the evolution of hominin reproductive strategies and the selective pressures leading to the derived suite of modern human traits.

许多灵长类动物行为和进化模式都严重依赖普遍研究的狒狒属。但是，与其他狒狒相比，相对研究的狒狒比其他物种表现出独特的物理和社会特征，建议在狒狒模型中应考虑的多种生殖策略。 该项目将收集有关狒狒的新数据，以了解其异常生物学的演变，从而促进了未来的比较研究，包括灵长类动物之间的交配系统多样性的演变，包括我们自己的人类谱系。该项目将促进研究生和本科生在研究的多个方面的培训，包括现场数据收集和处理，计算方法和实验室工作。该项目将通过各种媒体支持国际研究合作，对学生和当地社区的科学宣传，保护工作以及数据传播。 Kinda是我们缺乏详细生物学数据的唯一狒狒物种，并且是测试灵长类动物进化模型的出色物种。 Kinda Baboon具有独特的特征，包括减少性二态性和男性驱动的两性社会关系，这表明狒狒的生殖策略表现出比以前想象的更大的变化。该项目将检验以下假设，即与其他狒狒相比，有点狒狒发展出了表明直接弱且间接较强的男性竞争的特征。该项目有两个主要目标，to：1）表征在狒狒种群中观察到的交配系统和类型的生殖竞争； 2）表征这些特征对女性性信号的后果。我们将通过：i）女性生殖生活历史的特征； ii）生殖谱的荷尔蒙评估； iii）计算女性生殖同步和雄性生殖偏斜的计算； iv）女性性信号在广告女性生育中的可靠性。由于存在针对其他狒狒种群的这些参数的数据，因此我们将能够将我们的结果与其他狒狒分类单元的结果进行比较。该项目将导致有关野生狒狒繁殖的第一个详细纵向数据集，尤其是在生理和性信号方面。该项目将促进未来的比较研究，以了解灵长类动物和其他动物之间交配系统多样性的演变。此外，探索降低的性二态性的行为和生活历史的相关性，在有点狒狒和人类中观察到的特征，将为人类生殖策略的演变以及导致现代人类特征的派生套房的选择性提供重要见解。
