This has led to concern, exemplified in results from a recent survey conducted with members of the Cultural Evolution Society, that the field lacks 'knowledge synthesis', is poorly supported by 'theory', has an ambiguous relation to biological evolution and uses key terms (e.g. 'culture', 'social learning', 'cumulative culture') in ways that hamper operationalization in models, experiments and field studies. Although numerous review papers in the field represent and categorize its empirical findings, the field's theoretical challenges receive less critical attention even though challenges of a theoretical or conceptual nature underlie most of the problems identified by Cultural Evolution Society members. Guided by the heterogeneous 'grand challenges' emergent in this survey, this paper restates those challenges and adopts an organizational style requisite to discussion of them. The paper's goal is to contribute to increasing conceptual clarity and theoretical discernment around the most pressing challenges facing the field of cultural evolutionary science. It will be of most interest to cultural evolutionary scientists, theoreticians, philosophers of science and interdisciplinary researchers.}, keywords = {TRANSMISSION; Methods; theory; NATURAL-HISTORY; INDIVIDUALISM-COLLECTIVISM; anthropology; Language evolution; human gait; PROSOCIAL BEHAVIOR; cultural evolution; PUBLIC-GOODS; gene-culture co-evolution; gene coevolution; SUPERNATURAL PUNISHMENT}, year = {2024}, eissn = {2513-843X}, orcid-numbers = {Charbonneau, Mathieu/0000-0002-6786-8889; Kimbrough, Erik O./0000-0002-6495-0430; Scott-Phillips, Thom/0000-0002-9004-7093; Purzycki, Benjamin Grant/0000-0002-9595-7360} } @article{MTMT:34775448, title = {Sex ratios and gender norms: why both are needed to understand sexual conflict in humans}, url = {https://m2.mtmt.hu/api/publication/34775448}, author = {Hagen, R.V. and Scelza, B.A.}, doi = {10.1017/ehs.2024.3}, journal-iso = {Evolut.

Recently this theory has been extended to understand the resolution of sexual conflict in humans, but with mixed success. We argue that an underappreciation of the complex relationship between gender norms and sex ratios has hampered a successful understanding of sexual conflict in humans. In this paper, we review and expand upon existing theory to increase its applicability to humans, where gender norms regulate sex ratio effects on sexual conflict. Gender norms constrain who is on the marriage market and how they are valued, and may affect reproductive decision-making power. Gender norms can also directly affect sex ratios, and we hypothesize that they structure how individuals respond to market value gained or lost through biased sex ratios. Importantly, gender norms are in part a product of women’s and men’s sometimes conflicting reproductive interests, but these norms are also subject to other evolutionary processes. An integration of sexual conflict theory and cultural evolutionary theory is required to allow for a full understanding of sexual conflict in humans. © The Author(s), 2024.

As religious systems can bolster human relationships with a variety of mechanisms, the material insecurity hypothesis of religion posits that individual religiosity will increase under conditions of material insecurity. The bulk of the literature up to this point has been correlational and cross-national. Here, across 14 field sites, we examine the causal role that educational attainment and food insecurity play in religiosity. We find that years of formal education and food insecurity do not consistently contribute to individual religiosity cross-culturally. We conclude with a discussion of some theoretical and methodological implications. As a general workflow for cross-cultural causal research in the quantitative social sciences, the present work is a modest but necessary first step in reliably estimating causation in the material insecurity hypothesis of religiosity.}, year = {2024}, eissn = {2513-843X}, orcid-numbers = {Purzycki, Benjamin Grant/0000-0002-9595-7360; Bendixen, Theiss/0000-0001-5729-1281} } @article{MTMT:34668890, title = {US homicide rates increase when resources are scarce and unequally distributed}, url = {https://m2.mtmt.hu/api/publication/34668890}, author = {Mccool, Weston C. and Codding, Brian F.}, doi = {10.1017/ehs.2023.31}, journal-iso = {Evolut.

Almost all of these appeared in a narrow latitudinal band (the northern Subtropical Zone). I suggest that these developments were the result of a need to facilitate community bonding in response to scalar stresses that developed as community sizes increased dramatically beyond those typical of hunter-gatherer societies. Conditions for population growth (as indexed by rainfall patterns and the difference between pathogen load and the length of the growing season) were uniquely optimised in this zone, creating an environment of ecological release in which populations could grow unusually rapidly. The relationship between latitude, religion and language in contemporary societies suggests that the peculiar characteristics of the northern (but not the southern) Subtropical Zone were especially favourable for the evolution of large scale religions as a way of enforcing community cohesion.}, keywords = {LATITUDE; Holocene; Language evolution; pathogen load; Scalar stress}, year = {2023}, eissn = {2513-843X} } @article{MTMT:34296841, title = {Status-impact assessment: is accuracy linked with status motivations?}, url = {https://m2.mtmt.hu/api/publication/34296841}, author = {Durkee, Patrick K.

Position in hierarchies shows important links with fitness outcomes. Consequently, humans should possess psychological adaptations for navigating the adaptive challenges posed by living in hierarchically organised groups. One hypothesised adaptation functions to assess, track, and store the status impacts of different acts, characteristics and events in order to guide hierarchy navigation. Although this status-impact assessment system is expected to be universal, there are several ways in which differences in assessment accuracy could arise. This variation may link to broader individual difference constructs. In a preregistered study with samples from India (N = 815) and the USA (N = 822), we sought to examine how individual differences in the accuracy of status-impact assessments covary with status motivations and personality. In both countries, greater overall status-impact assessment accuracy was associated with higher status motivations, as well as higher standing on two broad personality constructs: Honesty-Humility and Conscientiousness. These findings help map broad personality constructs onto variation in the functioning of specific cognitive mechanisms and contribute to an evolutionary understanding of individual differences.}, keywords = {accuracy; Personality; Motivation; Individual differences; Status}, year = {2023}, eissn = {2513-843X} } @article{MTMT:34236458, title = {The cultural evolution of teaching}, url = {https://m2.mtmt.hu/api/publication/34236458}, author = {Brandl, Eva and Mace, Ruth and Heyes, Cecilia}, doi = {10.1017/ehs.2023.14}, journal-iso = {Evolut.

Some have argued that human teaching is a cognitive instinct - a form of 'natural cognition' centred on mindreading, shaped by genetic evolution for the education of juveniles, and with a normative developmental trajectory driven by the unfolding of a genetically inherited predisposition to teach. Here, we argue instead that human teaching is a culturally evolved trait that exhibits characteristics of a cognitive gadget. Children learn to teach by participating in teaching interactions with socialising agents, which shape their own teaching practices. This process hijacks psychological mechanisms involved in prosociality and a range of domain-general cognitive abilities, such as reinforcement learning and executive function, but not a suite of cognitive adaptations specifically for teaching. Four lines of evidence converge on this hypothesis. The first, based on psychological experiments in industrialised societies, indicates that domain-general cognitive processes are important for teaching. The second and third lines, based on naturalistic and experimental research in small-scale societies, indicate marked cross-cultural variation in mature teaching practice and in the ontogeny of teaching among children. The fourth line indicates that teaching has been subject to cumulative cultural evolution, i.e. the gradual accumulation of functional changes across generations.Social media summary: Teaching is an important means by which we transmit culture.
