  1. When does matriliny fail? The frequencies and causes of transitions to and from matriliny estimated from a de novo coding of a cross-cultural sampleShenk, Mary K. - Philosophical Transactions of the Royal Society B, 2019 - 2 Hypotheses

    Researchers looked at 180 of the 186 societies in the SCCS for changes over time in lineage systems. The goal was to estimate the frequency of transitions away from and to matriliny cross-culturally, as well as explore the potential causes of these patterns / transitions. The study focused on two overarching research questions: 1. How common are transitions away from matriliny and how often do ‘reverse transitions’ to matriliny occur? 2. What causes transitions to or from matriliny? Overall, the study found that transitions away from matriliny have been quite common within the time frames covered by the ethnographic samples available, while transitions from another system to matrility have been rare. In answering the second question, the researchers report the highest correlation is between subsistence transitions (towards pastoralism, intensive agriculture, or a market economy) and lineage transitions (away from matriliny) as well as between higher levels of social complexity (measured by stratification, slavery, and population size) and lineage transitions (away from matriliny).

  2. A worldwide view of matriliny: using cross-cultural analyses to shed light on human kinship systemsSurowiec, Alexandra - Philosophical Transactions of the Royal Society B, 2019 - 10 Hypotheses

    This article tested multiple previous hypotheses for associations between matriliny and cultural traits typically associated with stability and loss (subsistence strategy, animal domestication, mating system, residence pattern, wealth transfer, and property succession). Combining both genetic and linguistic data, researchers formed a phylogenetic ‘supertree’ that includes 16 matrilineal populations. Using this dataset they performed various analyses to assess patterns of evolution of matriliny and matrilocality.

  3. Unilocal residence and unilineal descent: a reconsiderationKorotayev, Andrey V. - World Cultures, 2004 - 4 Hypotheses

    This study focuses on the development of unilineal descent, reviewing previous theories and testing additional factors to explain the relationship between unilineal descent and unilocal residence. Results suggest four key factors leading to a low association between these two variables: insufficient alternatives to unilocal residence rule, instability of communal composition, absence of sedentary settlement pattern, and small average community size. A model linking all variables from the paper is presented.

  4. Social Practice and Shared History, Not Social Scale, Structure Cross-Cultural Complexity in Kinship SystemsRácz, Péter - Topics in Cognitive Science, 2019 - 6 Hypotheses

    Researchers examined kinships terminology systems for explanations regarding specifically observed typology of kin terms for cousins cross-culturally. They explore two theories, the first relating to population size via bottleneck evolution, and the second relating to social practices that shape kinship systems. Using the Ethnographic Atlas within D-PLACE, 936 societies with kinship system information were studied. The findings did not suggest a relationship between increased community size and a decrease in kinship complexity, however the research does suggest a relationship between practices of marriage and descent and kinship complexity.

  5. The status of women in preindustrial societiesWhyte, Martin King - , 1978 - 23 Hypotheses

    This book is concerned with explaining variation in the status of women. The author, after measuring over 50 aspects of status, first concludes that status is not a unitary concept. Therefore the author looks at 10 different domains of status. Many traditional explanations are not supported; most support is found for the influence of social complexity which generally lowers female status.

  6. Cassava production and processing in a cross-cultural sample of african societiesRomanoff, Steven - Behavior Science Research, 1992 - 12 Hypotheses

    This exploratory study seeks to explain cassava production and processing in Africa by considering cultural, agronomic, and environmental data. After examining the descriptive results of the agricultural and social contexts of cassava use, the authors build upon Boserup's population density model (1965) to analyze their own hypothesized model of cassava's importance among the sampled societies.

  7. Economic Systems of Foraging, Agricultural, and Industrial SocietiesFrederic L. Pryor - , 2005 - 26 Hypotheses

    The second and third parts of this book classify the economic systems of foraging and agricultural societies in the SCCS based on correlations between their institutions of property an distribution. These economic types are then examined for relationships with other social, political, demographic, and environmental factors in order to draw tentative conclusions regarding the origins of the Agricultural and Industrial Revolutions. The fourth part of the book uses cross-national data to examine similar associations in industrial/service economies, and is not included here.

  8. Phylogenetic analysis of the evolution of lactose digestion in adultsHolden, Clare - Human Biology, 1997 - 4 Hypotheses

    The ability of adults to digest lactose is common only in populations of European and circum-Mediterranean origin, a distribution thought to be a result of genetic adaptation to drinking milk from domestic livestock. Two additional hypotheses have been proposed to explain the distribution of high lactose digestion capacity: (1) supplemental calcium in high-latitude populations prone to vitamin D deficiency and (2) maintenance of water and electrolytes in the body in highly arid environments. However, these hypotheses are confounded by the shared ancestry of populations whose lactose digestion capability has been tested. Therefore, the authors test all three hypotheses using a phylogenetic comparative method for 62 cultures.

  9. The biogeographic origins of novelty-seeking traitsGören, Erkan - Evolution and Human Behavior, 2016 - 2 Hypotheses

    The researcher looks for empirical evidence of natural selection as an explanation for worldwide variation in novelty-seeking behavior. Examining the relationship between variability in frequency of the DRD4 exon III 7-repeat allele variant (a variant theorized to stifle dopamine reception and thus encourage compensatory novelty-seeking behavior) and migratory distance from prehistoric humans' origin point in East Africa yields a positive correlation. After controlling for various biogeographic indicators, the researcher theorizes that presence of the DRD4 exon III 7-repeat variant provided an exploratory urge and evolutionary advantage to hunter-gatherers and pastoralists who migrated into unfamiliar environments.

  10. Kinship and polity in stateless societiesPaige, Jeffery M. - American Journal of Sociology, 1974 - 4 Hypotheses

    This article suggests a theory of the relationship between rules of descent and polity structure. The author suggests that “polity structure in stateless societies is a consequence of the presence or absence of cohesive factions based on lineage or family” (301). Two types of kinship ties produce different polity structures: cross-cutting ties, common in matrilineal societies, lead to political consensus; overlapping ties, common in patrilineal societies, lead to factionalism. Empirical tests support this theory.
