Primates show diverse patterns of adaptive color and body size dimorphism produced by inter- and intrasexual selection. However, the specific microevolutionary processes that produce variation in secondary sexual characteristics remain largely unexplored in primates. Furthermore, sexual conflict theory predicts that female and male secondary sexual traits can coevolve in an antagonistic manner and promote speciation. This dissertation explores the microevolution of secondary sexual characteristics in mandrills (Mandrillus sphinx) and the macroevolution of these characters in anthropoid primates. I address the microevolution of mandrill facial coloration and body mass by estimating the heritability, phenotypic selection, and genetic evolution of these traits …

Intergenerational Embodiment Of Stress : How The Broader Sociocultural Environment Can Shape Child Growth And Development, Elizabeth A. Holdsworth

Childhood growth has been a means of identifying systemic, material inequalities within populations. The plasticity of growth is responsive to multiple environmental factors, most notably adequate nutrition, but also psychosocial stress. Psychosocial stress can be a function of the social and political economic ecology, reinforcing power hierarchies within societies. This dissertation proposes that childhood growth can also reflect inequality in the distribution of psychosocial stress exposure through mothers’ feelings of a chronically stressful environment conveyed through maternal-infant interactions.
