Historical censuses of Inuit (Canadian and North Alaskan Eskimos) often contain highly male-biased juvenile sex ratios that have been interpreted as evidence of female infanticide. We use model life tables to estimate elements of historic Inuit population structure missing from the censuses themselves and use these estimates to examine the major explanations for Inuit sexratio bias found in the literature. The argument hat sex-ratio bias is primarily an artifact of incorrect age assessment due… 
Why so many Agta boys? Explaining ‘extreme’ sex ratios in Philippine foragers
The results are not supportive of female infanticide or neglect, and instead suggest an adaptive mechanism, acting in utero as a response to male-biased juvenile mortality, following Fisherian principles of equalising parental investment.
The Evolutionary Demography of Sex Ratios in Rural Bangladesh
In this chapter, we use evolutionary models of sex ratio variation to examine offspring sex ratios in Matlab, Bangladesh, from the 1960s to 2010, during which time sex ratios have shown a decreasing
Preference for sons and sex ratio in two non‐western societies
The results suggest either that despite the social valorization of male progeny no differences in parental care according to sex occur, or that their magnitude is not great enough to contrast the survival of sons and daughters.
Gender and Risk in a Matrifocal Caribbean Community: A View from Behavioral Ecology
Matrifocality is a feature of Caribbean communities in which mothers and adult daughters often form the household core. I argue that daughter-biased parental care underlies matrifocality. Parental
Sexual dimorphism in stature and women's work: a phylogenetic cross-cultural analysis.
The following cultural variables were tested for their association with sexual dimorphism: sexual division of labor, type of subsistence, and polygyny, and all the traits were found to be associated with phylogeny, indicating that they are inherited from mother to daughter populations.

Results are interpreted as competition between same-sex siblings for parental investment, in the form of their father’s herd, which is more intense between sons than daughters as parental investments are greatest in males.
Sex preference for children in a Meifu Li community in Hainan, China
Sex preferences for children are contingent on institutional and economic contexts, including family system. While the patrilineal joint family system of the Han Chinese tends to devalue daughters,
Brothers and sisters
Data from the Kipsigis of Kenya are used to test two models for how parents invest in offspring, the Trivers-Willard and local resource competition/enhancement hypotheses, and to bring to bear on the question of why sex preferences are so muted in Africa.
Greco-Roman Sex Ratios and Femicide in Comparative Perspective
Is it possible to demonstrate that ancient Greeks or Romans disposed of newborn daughters in ways that skewed sex ratios in favor of males? Epigraphic, papyrological, and archaeological evidence


Population, Warfare, and the Male Supremacist Complex
A demographic analysis of 561 local band and village populations fro m 112 societies found that male-supremacy social patterns were overwhelmingly predominant and that this male supremacy complex
Trivers-willard rules for sex allocation
A quantitative model of sex allocation is presented to investigate whether the simple “rules of thumb” suggested by Trivers and Willard (1973) would really maximize numbers of grandchildren in human populations and shows that sex-specific infanticide will almost never achieve the goal of maximizing expected numbers of grandparents.
Infanticide and fertility among Eskimos: a computer simulation.

Eskimo beliefs regarding the effects of infanticide on fertility are in accord with the results of research on the relation of fertility and lactation, and the present computer simulation indicates that Eskimo populations could sustain a rate of 30% female infanticides and still survive.
