AbstractThe cultural evolutionary processes outlined by Singh illuminate why ritualized behaviors aimed at controlling unseen forces and overcoming fear are common in warfare among many small-scale societies. They also suggest an explanation for the development of ritual specialists for war who are distinct from war leaders.

Abstract Behavioral genetics and cultural evolution have both revolutionized our understanding of human behavior—largely independent of each other. Here we reconcile these two fields under a dual inheritance framework, offering a more nuanced understanding of the interaction between genes and culture. Going beyond typical analyses of gene–environment interactions, we describe the cultural dynamics that shape these interactions by shaping the environment and population structure. A cultural evolutionary approach can explain, for example, how factors such as rates of innovation and diffusion, density of cultural sub-groups, and tolerance for behavioral diversity impact heritability estimates, thus yielding predictions for different social contexts. Moreover, when cumulative culture functionally overlaps with genes, genetic effects become masked, unmasked, or even reversed, and the causal effects of an identified gene become confounded with features of the cultural environment. The manner of confounding is specific to a particular society at a particular time, but a WEIRD (Western, educated, industrialized, rich, democratic) sampling problem obscures this boundedness. Cultural evolutionary dynamics are typically missing from models of gene-to-phenotype causality, hindering generalizability of genetic effects across societies and across time. We lay out a reconciled framework and use it to predict the ways in which heritability should differ between societies, between socioeconomic levels and other groupings within some societies but not others, and over the life course. An integrated cultural evolutionary behavioral genetic approach cuts through the nature–nurture debate and helps resolve controversies in topics such as IQ.

This article offers a new perspective on the century-old discussion of sacral rulers in the history of religions generally, and pre-Christian Scandinavian religions specifically, namely the application of a cultural evolutionary theoretical framework based on the work of Robert N. Bellah. In doing this, the article opens the possibility of wider typological comparisons within this paradigm and suggests a nuancing of Bellah’s typology with the addition of the category of ‘chiefdom religion’. This is utilised in the main part of the article, which features a comparison between the figure of the sacral ruler in pre-Christian Scandinavian and pre-Christian Hawaiian religions through an analysis of: 1) the position of the ruler in society, cult, and ideology; 2) the societal structure in which these religions are found; 3) the idea of a ruler sacrifice; 4) incestuous relationships and their ideological implications; and, finally, 5) the idea of a double rulership. Following this comparison, the perspectives in and the usefulness of cultural evolutionary theories in the history of religions are briefly evaluated.

Culture is a human universal, yet it is a source of variation in human psychology, behaviour and development. Developmental researchers are now expanding the geographical scope of research to include populations beyond relatively wealthy Western communities. However, culture and context still play a secondary role in the theoretical grounding of developmental psychology research, far too often. In this paper, we highlight four false assumptions that are common in psychology, and that detract from the quality of both standard and cross-cultural research in development. These assumptions are: (i) the universality assumption , that empirical uniformity is evidence for universality, while any variation is evidence for culturally derived variation; (ii) the Western centrality assumption , that Western populations represent a normal and/or healthy standard against which development in all societies can be compared; (iii) the deficit assumption , that population-level differences in developmental timing or outcomes are necessarily due to something lacking among non-Western populations; and (iv) the equivalency assumption , that using identical research methods will necessarily produce equivalent and externally valid data, across disparate cultural contexts. For each assumption, we draw on cultural evolutionary theory to critique and replace the assumption with a theoretically grounded approach to culture in development. We support these suggestions with positive examples drawn from research in development. Finally, we conclude with a call for researchers to take reasonable steps towards more fully incorporating culture and context into studies of development, by expanding their participant pools in strategic ways. This will lead to a more inclusive and therefore more accurate description of human development.

AbstractThis essay discusses Cecilia Heyes’ groundbreaking new book Cognitive Gadgets: The Cultural Evolution of Thinking. Heyes’ point of departure is the claim that current theories of cultural evolution fail adequately to make a place for the mind. Heyes articulates a cognitive psychology of cultural evolution by explaining how eponymous “cognitive gadgets,” such as imitation, mindreading and language, mental technologies, are “tuned” and “assembled” through social interaction and cultural learning. After recapitulating her explanations for the cultural and psychological origins of these gadgets, we turn to criticisms. Among those, we find Heyes’ use of evolutionary theory confusing on several points of importance; alternative theories of cultural evolution, especially those of the Tomasello group and of Boyd, Richerson and Henrich, are misrepresented; the book neglects joint attention and other forms of intersubjectivity in its explanation of the origins of cognitive gadgets; and, whereas Heyes accuses other theories of being “mindblind,” we find her theory ironically other-blind and autistic in character.

AbstractShamans, including medicine men, mediums, and the prophets of religious movements, recur across human societies. Shamanism also existed among nearly all documented hunter-gatherers, likely characterized the religious lives of many ancestral humans, and is often proposed by anthropologists to be the “first profession,” representing the first institutionalized division of labor beyond age and sex. In this article, I propose a cultural evolutionary theory to explain why shamanism consistently develops and, in particular, (1) why shamanic traditions exhibit recurrent features around the world; (2) why shamanism professionalizes early, often in the absence of other specialization; and (3) how shifting social conditions affect the form or existence of shamanism. According to this theory, shamanism is a set of traditions developed through cultural evolution that adapts to people's intuitions to convince observers that a practitioner can influence otherwise unpredictable, significant events. The shaman does this by ostensibly transforming during initiation and trance, violating folk intuitions of humanness to assure group members that he or she can interact with the invisible forces that control uncertain outcomes. Entry requirements for becoming a shaman persist because the practitioner's credibility depends on his or her “transforming.” This contrasts with dealing with problems that have identifiable solutions (such as building a canoe), in which credibility hinges on showing results and outsiders can invade the jurisdiction by producing the outcome. Shamanism is an ancient human institution that recurs because of the capacity of cultural evolution to produce practices adapted to innate psychological tendencies.

Cultural evolutionary theory and human behavioural ecology offer different, but compatible approaches to understanding human demographic behaviour. For much of their 30 history, these approaches have been deployed in parallel, with few explicit attempts to integrate them empirically. In this paper, we test hypotheses drawn from both approaches to explore how reproductive behaviour responds to cultural changes among Mosuo agriculturalists of China. Specifically, we focus on how age at last birth (ALB) varies in association with temporal shifts in fertility policies, spatial variation and kinship ecologies. We interpret temporal declines in ALB as plausibly consistent with demographic front-loading of reproduction in light of fertility constraints and later ages at last birth in matrilineal populations relative to patrilineal ones as consistent with greater household cooperation for reproductive purposes in the former. We find little evidence suggesting specific transmission pathways for the spread of norms regulating ALB, but emphasize that the rapid pace of change strongly suggests that learning processes were involved in the general decline in ALB over time. The different predictions of models we employ belie their considerable overlap and the potential for a synthetic approach to generate more refined tests of evolutionary hypotheses of demographic behaviour.

Abstract Half a century ago, Uriel Weinreich, William Labov, and Marvin Herzog laid out a programmatic vision for the study of language change. This included establishing five fundamental problems for the field and a radical shift from a focus on idiolects to a focus on population-level change (grounded in their concept of orderly heterogeneity). They also expressed an explicit desire to see an integrated evolutionary study of language change. In spite of this, the newer fields of language evolution and cultural evolution make little contact with the field of sociolinguistics that emerged out of their work. Here we lay out a program, grounded in their five problems, for a more integrated future. We situate each problem in modern sociolinguistics and identify promising points for theoretical exchange, making comparisons with Tinbergen’s four questions, which play a similar role in the evolutionary sciences. Finally, we propose cultural-evolutionary experiments for making empirical progress.

AbstractCultural evolution research is the study of how cultural traits (e.g., beliefs and behavioral patterns) stabilize, change and diffuse in populations, and why some cultural traits are more “attractive” (i.e., more likely to spread) than others. As such, cultural evolution is highly relevant for the emerging “science of science communication” (SSC) in that it can help organize and guide the study of science communication efforts aimed at spreading scientifically accurate information and inspiring behavioral change. Here, I synthesize insights and theory from cultural evolution with central findings and concepts within the SSC with the aim of highlighting the inherent, but underexplored, consilience between these two fields. I demonstrate how cultural evolution can serve as an unifying framework for the SSC and how, conversely, science communication can serve as a fertile testing ground for applying, exploring, and advancing cultural evolutionary theory in a real-world setting that matters. Lastly, I highlight merits and limitations of previous applications of cultural evolution to science communication and conclude with some particularly outstanding questions that emerge at the intersection between cultural evolution and science communication research.

China has maintained strong relationships with many African countries, and Ghana is one such country. While the two countries have normally enjoyed good friendly relations, concerns over the involvement of Chinese citizens in small-scale mining in Ghana threaten the cordial relationship between the two countries. There is evidence of a cultural evolution and a gradual shift from a culture of enthusiastic reception of local people to the Chinese in the area of mining to one of cold reception to Chinese interests in mining communities. There is also evidence that this cold reception to Chinese miners is stimulated by non-state actors led by the media and inspires in Ghana a new paradigm of more rational engagement with China at the political level, although challenges still remain.
