Authors use genealogical data to investigate pair bond stability and reproductive skew across a sample of 80 small-scale societies. Results suggest that male reproductive skew and pair-bond stability are independent sources of cross-cultural variation in human mating patterns.

This study tests three hypotheses on the evolution of the human pair-bond: male-provisioning, male mating competition, and the defense of offspring from other males. Findings indicate that male provisioning and mating competition are factors in the development of the pair-bond. Additional findings indicate that alloparentling, polygyny, and equal contribution to subsistence by each sex contribute to the security of the pair-bond.

This article explores narcissism and child-rearing. The author presents a theory that, if a society’s structural pattern weakens the marital bond, the mother will be ambivalent toward the son who consequently will become narcissistic. This process would reinforce itself as it is repeated by each generation.

This study tests the relationship between mobility and technology among foragers, with the intent of applying findings to the archaeological record. In data analysis, mobility frequency is differentiated from mobility magnitude, and technological diversity is differentiated from technological complexity. Results suggest that mobility frequency is negatively associated with technological diversity while mobility magnitude is negatively associated with technological complexity.

Using both archaeological data from the Mesa Verde region and a Human Relations Area Files random sample of 25 worldwide societies, and another 10 from the American Southwest, the author looked to examine the relationship between changes in community size and settlements, agriculture intensification, and rules governing resource access. In particular the researcher wanted to examine the size of the group that controls the primary access to the main resource. After studying this global sample, the author takes an ethnographic look specifically at the Northern Anasazi in southewestern Colorado.

The author sampled 28 nonhierarchical, sedentary (at least partially), and demographically documented societies to examine the presence, size, and use of socially integrative facilities. Examing the ethnographic record from the Human Relations Area Files, the author looked to test the assumption that kivas were intended for communal ritual activity.

The dissertation in its entirety is an archaeological investigation of population aggregation among the Mesa Verde region Anasazi A.D. 900-1300. Chapters four and five of Adlers larger work focus on cross-cultural perspectives to inform discussion around resource access and community strength. Multiple different hypotheses were tested with different data sets, but the HRAF database and Standard Cross Cultural Sample were used throughout.

Researchers looked at four different demographic scenarios (altered mean vital rates (i.e., fertility and mortality), vital rate stochasticity, vital rate covariance, and periodic catastrophes) and their possible effects on the rapid population growth of contemporary human foragers and steady population decline of chimpanzees. They evaluated these variables and the various conditions that would favor a more sustainable zero population growth (ZPG) among 10 small-scale subsistence human populations (Agta, Ache, Hadza, Hiwi, Ju/’hoansi, Gainj, Tsimane, Yanomamo, Northern Territory Aborigines, and Herero) and five wild chimpanzee groups (Gombe, Kanyawara, Mahale, Ngogo, and Taï). The results state that the most effective modifications towards ZPG would include a combination of more than one of the four demographic scenarios tested, with the most realistic solution including both vital rate alteration and an increase in catastrophes.

While it is widely accepted that there are a multitude of variables that contribute to a society’s level of democracy, the authors of this study argue that the prevalence of consanguinity is one that is often overlooked. Using a sample of 70 nations, they tested the relationship between consanguinity (defined as marriage and subsequent mating between second cousins or closer relatives) and level of democracy (defined by both the Polity IV scale and the EIU Index) and found a significant negative relationship. Similarly, when controlled for a host of different variables in multiple regression analysis, the significant relationship between consanguinity and level of democracy held true.

This article seeks to reevaluate the widespread assumption that hunter-gatherers lack the longevity that people in the modern, industrialized world enjoy. Through modeling life expectancy, mortality, and other demographic trends among extant hunter-gatherer, gatherer-horticulturalists, and horticulturalists societies they are able to challenge this belief. The authors conclude that longevity is a "novel feature of Homo sapiens" and that seven decades seems to be the natural lifespan of a human.
