Despite the extraordinary diversity of behavior across the animal kingdom, the genes and molecules that contribute to such natural diversity are largely unknown. In this thesis, I leverage the dramatic divergence in behavior between two closely related species of deer mice (genus Peromyscus) to investigate the genetic, cellular, and neuroendocrine basis of behavior. In chapter 2, I show that the monogamous oldfield mouse (Peromyscus polionotus subgriseus) has evolved a novel cell type in the adrenal gland that expresses the enzyme AKR1C18, which converts progesterone into 20α-hydroxyprogesterone (20α-OHP). I then demonstrate that 20α-OHP is more abundant in oldfield mice than in the closely-related promiscuous prairie deer mouse (P. maniculatus bairdii) and that it increases monogamous-typical parental behaviors when administered to both monogamous fathers. Using quantitative trait locus mapping in a cross between these species, I discover interspecific genetic variation that drives expression of the glycoprotein tenascin N and ultimately contributes to gain of adrenal AKR1C18 expression in oldfield mice. In chapter 3, I investigate the genetic architecture underlying the striking difference in exploratory behavior between prairie deer mice and oldfield mice. Through congenic fine-mapping, I identify a 15-Mb locus that strongly contributes to species differences in exploratory behavior. I then investigate the potential contributions of one of the 18 genes in the locus, Olfm4, which harbors cis-regulatory variants that drives its expression in the oldfield hypothalamus. Taken together, my research advances our understanding of the genetic and molecular causes that drive rapid behavioral divergence between species.
