  1. Folktale transmission in the arctic provides evidence for high bandwidth social learning among hunter–gatherer groupsRoss, Robert M. - Evolution and Human Behavior, 2016 - 4 Hypotheses

    The myths, legends, and folktales of nearby groups tend to more alike than those of more distant groups. Three competing models attempt to explain this distribution of cultural traits: (1) vertical transmission, (2) horizontal transmission, and (3) independent innovation. The authors examine 18 Arctic hunter-gatherer groups to quantify the extent to which geographic distance, cultural ancestry, and effective population size predict overlap in folktale inventories.

  2. Post-marital residence patterns show lineage-specific evolutionMoravec, Jiri C. - Evolution and Human Behavior, 2018 - 1 Hypotheses

    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.

  3. Kinbank: A global database of kinship terminologyPassmore, Sam - PLoS ONE, 2023 - 2 Hypotheses

    Kinbank is a global database of 210,903 kinship terms derived from 1,229 spoken and signed languages. The authors created Kinbank as a tool to help explain recurring patterns across cultures through kinship terminology. They illustrate its usefulness by addressing two questions as an example: 1) Is there gender bias in the phonological structure of parent terms? and 2) Did bifurcate-merging terminology and cross-cousin marriage co-evolve in Bantu languages? Using a Bayesian phylogenetic approach, the authors find support for the first question, but none for the latter.
