Using linguistic trees as models of population history in combination with ethnographic data on kinship, the authors of the present study reconstruct post-marital residence rules of early Austronesian societies. Analyses include a Markov-chain Monte Carlo comparative method implemented in a Bayesian phylogenetic framework.

This paper builds on previous Austronesian dispersal research that indicated rituals and social complexity gave rise to each other, by examining if marital residence and initiation rites co-evolved during the dispersal. Using a phylogenetic test and initiation data from 79 societies, the authors found evidence that female and male initiation rites co-evolved during the dispersal and were most stable when both initiation rites were present. The authors also suggest that proto-Austronesian society probably lacked initiation rites and such rites only developed later.

This article investigates which sexual behaviors are tabued (tabooed) and the frequency and severity of their punishments. Results indicate that incest, abduction, and rape are more frequently tabued, and that frequent tabuing is associated with more severe punishment. Human and supernatural agency in punishment is also examined.

How is the evolution of language shaped by speaker population size? Through comparative data analyses of 153 language pairs from the Austronesian, Indo-European, and Niger-Congo language families, the authors find that the influence of population size on language evolution is not the same in the three language families. Only in Indo-European languages did a smaller population size of language-speakers significantly predict more word loss.

This paper investigates the relationship between marital residence and warfare. The author evaluates two theories proposing opposite causalities: one, that internal warfarecauses patrilocality; the other, that residence comes first and influences type of warfare. The author presents a new model emphasizing the role of population size in determining type of warfare, which in turn affects marital residence. However, the role of migration in determining marital residence is also considered.

Researchers examine post-marital residence patterns across five language phylogenies encompassing 371 ethnolinguistic groups. These language families are the Austronesian (Island Southeast Asia and the Pacific), Bantu (Sub-Saharan Africa), Indo-European (Eurasia), Pama-Nyungan (Australia), and Uto-Aztecan (Western USA and Mesoamerica). Contrary to the study's predictions, post-marital residence patterns did not evolve in similar ways across geographical regions but at a pace specific to its lineage.

Textor encapsulates cross-cultural findings on marital residence relating to cultural, environmental, psychological, and social phenomena.

Previous research has found that words are replaced faster in language vocabularies the less the word is used, whereas words that are used more frequently endure longer. Drawing from this theory, the authors of this article propose two questions: 1) Is the rate of replacement for Indo-European kinship terms correlated with their usage frequency? 2) How does this relationship differ between kinship terms and core vocabulary? Using phylogenetic comparative methods to analyze 10 kinship categories from 47 Indo-European languages, the authors find that more frequently used kinship terms tend to be replaced at a much slower rate than less frequently used words. Furthermore, this relationship between word replacement rate and usage frequency is stronger for kinship terms than it is for core vocabulary terms.

This study tests an adaptational theory of military organization. Test of the relationship between population, residence type and military organization are presented; findings support the hypotheses.

This chapter offers an exploratory study that examines the relationships between several culture characterstics, including child socialization practices, social structure, and food production, and mind-altering drug use in non-literate societies. All hypotheses were supported.
