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.

The authors examine the relationship between magico-religious practitioner type and socioeconomic variables in order to present a typology of magico-religious practitioners. Three bases for magico-religious practitioners are discussed in terms of selection procedures and activities. Several hypotheses are empirically tested, and descriptive generalizations derived from analyses are presented.

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.

Expanding on the author’s previous findings, this article examines the social and economic variables that may explain the cultural evolution of religious practitioners. With a 47 society sample, the author found that subsistence activities and socio-political conditions predict magico-religious practitioner types (sorcerers/witches, priests, shamanistic healers, mediums, healers, shaman/healers, and shamans) with the strongest results being from subsistence and political organization. He then used these findings to theorize about the biogenetic bases of religion in societies.

In the present study, Peregrine tests two perspectives regarding social resilience to climate-related disasters: 1) that societies with more inclusive and participatory political structures (corporate political strategies) are more resilient to climate-related disasters, and 2) that societies with tighter adherence to social norms are more resilient to climate-related disasters. Results support the notion that societies with greater political participation are more socially resilient to catastrophic climate-related disasters. Because these results are justifiably generalizable across multiple historical and cultural contexts, Peregrine's findings are a useful contribution to aid in disaster response policy decision making.

"This paper presents an exploratory attempt to solve the problem of how to infer traits for which no direct material evidence remains." The author suggests that the archeologically defined community pattern can predict several sociocultural traits. Results support this hypothesis.

The author builds upon previous research (Winkelman 1998) to further elucidate the cross-cultural predictors of institutionalized human sacrifice. The author considers a range of ecological factors and political variables, particularly geopolitical dynamics and intra- and inter-group relations. Other factors were explored, including social complexity and social structures. The author identifies the lack of an effective superordinate political authority as a main determinant in similar behaviors contemporarily (e.g. suicide bombers, beheadings, public brutality in civil war).

This study tests the relationship between population pressure and social evolution in agricultural societies. The author predicts that population pressure will be positively related to the evolution of descent, political integration, and class stratification. Results support this prediction.

This article uses the Standard Cross-Cultural Samples to test the relationship between disease and economic growth among sub-Saharan African societies. The authors suggest that a higher disease prevalence limits social integration and economic development since pre-colonial times. The variable measuring economic growth is the complexity of large or impressive structures. The hypotheses are that 1) pathogen stress is negatively correlated to the presence of complex buildings, and 2) pathogen stress is positively correlated to increased ethnic diversity. The results support both hypotheses, and there are additional results, like 1) the negative correlation between pathogen stress and current income per capita and 2) the negative correlation between the increased ethnic diversity and current income per capita. Overall, this article shows the robust relationship between disease and economic development.

This article proposes that ground plans may be used as a criterion for determining the relative permanence of settlement patterns in archaelogical societies. Results suggest that impermanent settlements and small community size are significantly associated with circular ground plans and that permanent settlements with larger community sizes are significantly associated with rectangular ground plans.
