One key question in social evolution is the identification of factors that promote the formation and maintenance of stable bonds between females and males beyond the mating context. Baboons lend themselves to examine this question, as they vary in social organisation and male-female association pattern...

They are briefly discussed here as a prologue to the main subject of this chapter, that is how evolution shapes primate birth sex ratios.In primates, age-specific mortality is generally higher for males than females, and males have shorter life expectancies than females (Fedigan and Zohar 1997...
Sex differences in human gregariousness Joyce F. Benenson, Sandra Stella and Anthony Ferranti Emmanuel College, Boston, MA, USA ABSTRACT Research on human sociality rarely includes kinship, social structure, sex, and familiarity, even though these variables influence sociality in non-human primates. ...
The data was collected from a review of the literature concerning the evolution of neurobiological factors of sexual behaviour in mammals. Several studies, in biology, genetics and neurosciences, have shown that some of these factors have changed over the course of evolution. In primates, ...
Because women are more likely than men to use social status as a criterion in mate selection, evolutionary theory has led to the hypothesis that higher proportions of males will be born to parents of high social status than to parents of low status. To date, the research that has tested th...
In contrast, in monogamous species where male competi- tion is less severe, the number of species with longer male longevity (4 species out of 9 species; 44%) becomes slightly more than a half (Fig. 2d)15. If we limit the data to primates, 5 species out of 6 exhibit longer female ...
It is therefore important to test for the existence of a payoff-biased strategy in non-human primates. Moreover, humanity’s success as a species depends on cumulative culture, and such a test could also allow us to better understand the evolution of cumulative culture because a payoff-biased...
