Cultures vary widely in regards to beauty standards for female body fat: while industrialized nations typically prefer thinness in women, ethnographic reports indicate that plumpness is valued in many small-scale societies. Here the authors evaluate several hypotheses that relate variation in female body fat preference to variation in socioecology such as food storage, climate, male social dominance, valuation and restriction of women's work, and female stress during adolescence.

This study is a comprehensive analysis of female and male genital mutilation/cutting (FGM/C and MGM/C) practices, including their history and socio-ecological correlates, using a phylogenetic cross-cultural framework. It employed two global ethnographic samples, the Ethnographic Atlas (EA) and the Standard Cross-Cultural Sample (SCCS), and two subsets of the phylogeny (supertree) of human populations based on genetic and linguistic data, to investigate the variables that may have led to the introduction of these practices, and to determine where and when they may have originated. The study suggests that MGM/C probably originated in polygynous societies with separate residence for co-wives, supporting a mate-guarding function, and that FGM/C likely originated subsequently and almost exclusively in societies already practicing MGM/C, where it may have become a signal of chastity. Both practices are believed to have originated multiple times, some as early as in the mid-Holocene (5,000–7,000 years ago). The study posits that GM/C co-evolves with and may help maintain fundamental social structures and that the high fitness costs of FGM/C are offset by social benefits, such as enhanced marriageability and social capital.

This article presents codes for adolescent initiation ceremonies in the standard cross-cultural sample. Commonly held assumptions about initiation ceremonies were not supported. Article focuses on differences between male and female ceremonies. Statistically significant correlations between the codes are indicated.

This article focuses on the relationship between premarital sexual behavior in childhood and adolescence. New measures and ratings of sexual behavior are presented. Findings supp ort the prediction that sexual behavior in childhood correlates with sexual behavior in adolescence in societies where there is an emphasis on continuity from childhood to adolescence.

This article explores the association between father-son relationships and bridewealth. Bridewealth becomes an instrument through which male parents impose their will on their male offspring. The hypotheses are supported by the results presented.
