Extensive adaptation for the care of young infants has been a major, defining characteristic of human and non-human primate evolution. In fact, despite obvious differences in patterns of infant care in humans and other primates, many of the biological factors underlying variation in parenting behavior are probably very similar in humans and other anthropoid primates. Research on the biological causes and consequences of variation in parenting behavior in non-human primate species, especially those phylogenetically closest to humans, i.e. Old World monkeys and apes, can yield new perspectives, information and insight into the origins of variation in human parenting.Endocrine correlates and fitness consequences of variation in mothering behavior will be investigated for 45 females of known behavioral and demographic history in five groups of wild yellow baboons (Papio cynocephalus) in Amboseli, southern Kenya. Using patterns of behavior, noninvasive fecal hormone sampling, and the Amboseli long-term database, this study will examine the extent to which (1) differences in the mother-infant relationship are predictable from differences among mothers in the profiles of four steroid hormones over late pregnancy and early lactation and (2) differences in the mother-infant relationship predict variation (a) in mothers' future reproduction and (b) infant survivorship.This project builds on and considerably extends previous research on this topic in non-human primates, which have primarily been constrained to a few individuals of a few species, captive populations, one or two hormones, and invasive hormone sampling. This project represents one of the first rigorous investigations of the biological forces underlying variation in mothering behavior in a wild nonhuman primate population. In focusing on one of the most socially complex and closely related animal models, this project will enhance our understanding of human origins and yield new information and insight into the origins of variation in human parenting while avoiding many of the logistical and ethical difficulties often entailed in studying humans. Furthermore, this study will enhance our understanding of variation in the mother-infant relationship in wild populations and will make important contributions to a comprehensive analysis of life-history variation in wild primates.In supporting this project, NSF is supporting a major part of the Ph.D training of the co-PI, Nga Nguyen, a first-generation Vietnamese American and the first of her family to receive post-secondary school education. Nguyen has received sponsorship for her research in Kenya through the Institute of Primate Research (IPR), National Museums of Kenya. Nguyen will present preliminary findings of her study in Kenya at IPR and will produce a variety of technical publications spanning several appropriate disciplinary areas, including behavioral ecology, behavioral endocrinology, and biological anthropology. A section of the publicly available Amboseli Baboon Project website (www.princeton.edu/~baboon) will be devoted to this project.

广泛的适应照顾年幼的婴儿一直是人类和非人类灵长类动物进化的主要特征。事实上，尽管人类和其他灵长类动物在照顾婴儿的模式上存在明显差异，但导致养育行为差异的许多生物学因素在人类和其他灵长类动物中可能非常相似。研究非人类灵长类物种，特别是那些在遗传学上与人类最接近的物种，即旧大陆的猴子和猿，养育行为变异的生物学原因和后果，可以产生新的观点，信息和洞察的起源变化，在人类养育。内分泌相关和健身后果的变化，在母亲的行为将被调查的45名女性的已知行为和人口在肯尼亚南部的安博塞利，五群野生黄色狒狒（Papio cynocephalus）的历史 利用行为模式、非侵入性粪便激素采样和安博塞利长期数据库，本研究将探讨（1）母婴关系的差异在多大程度上可从母亲在妊娠晚期和哺乳早期四种类固醇激素谱的差异中预测;（2）母婴关系的差异预测（a）母亲未来生殖的变化和（B）婴儿存活率：该项目建立在以前关于非人类灵长类动物这一主题的研究的基础上，并在很大程度上扩展了这一研究，这些研究主要局限于少数物种的少数个体、圈养种群、一两种激素和侵入性激素采样。该项目代表了对野生非人灵长类种群中母性行为变化背后的生物力量的第一次严格调查。在专注于最复杂的社会和密切相关的动物模型之一，这个项目将提高我们对人类起源的理解，并产生新的信息和洞察人类养育的变异的起源，同时避免了许多后勤和伦理上的困难往往在研究人类。此外，这项研究将提高我们对野生种群中母婴关系变化的理解，并将为全面分析野生灵长类动物的生活史变化做出重要贡献。在支持这个项目的过程中，NSF支持了第一代越南裔美国人Nga Nguyen的博士培训的主要部分，她是她家族中第一个接受高等教育的人。Nguyen通过肯尼亚国家博物馆灵长类动物研究所（IPR）获得了她在肯尼亚的研究赞助。Nguyen将在IPR上展示她在肯尼亚研究的初步发现，并将出版涵盖多个适当学科领域的各种技术出版物，包括行为生态学、行为内分泌学和生物人类学。 公开的安博塞利狒狒项目网站（www.princeton.edu/baboon）将专门介绍这一项目。
