Cultural epigenetics

Integrating cultural evolution and behavioral genetics

The 29 commentaries amplified our key arguments; offered extensions, implications, and applications of the framework; and pushed back and clarified. To help forge the path forward for cultural evolutionary behavioral genetics, we (1) focus on conceptual disagreements and misconceptions about the concepts of heritability and culture; (2) further discuss points raised about the intertwined relationship between culture and genes; and (3) address extensions to the proposed framework, particularly as it relates to cultural clusters, development, and power. These commentaries, and the deep engagement they represent, reinforce the importance of integrating cultural evolution and behavioral genetics.

Ethology of the Freed Animal. Concept, Paradigm and Implementations to the Moral Status of Non-Human Animals

The essay focuses on the methodological and theoretical premises of an emerging research area with both ethological and (bio)ethical implications: the ethology of the freed animal (EFA). Unlike existing ethological fields, EFA does not focus on the observation of nonhuman (NH) animals in a natural condition of freedom, nor on situations of captivity. Rather, EFA consists of a comparative study of NH animals that are removed from a condition of captivity, from the status of “living tool” of human beings and from any form of exploitation – instead relocated in an environment fairly appropriate to their speciesspecific and individual characteristics. Ideal places for this study are animal sanctuaries and parks/reserves where a previously captive NH animal can be reintroduced in their natural habitat or, when this proves impossible, in a contest appropriate to their characteristics and needs. Even though EFA exists already, as a de facto practice of the personnel running sanctuaries and parks, the field still lacks a recognizable scholarly paradigm, and is not yet acknowledged at institutional/academic level, nor were its moral implications thoroughly discussed. Consequently, one important aim for such a field is the establishment of an active interaction between the two parties involved (researchers and sanctuaries/parks operators).

Managing health in inequitable contexts: Health capacities as integral to life course health development

Health behavior models are widely used in prevention research with children and adolescents; yet, many of these models were developed based on adult experiences and fail to consider the development of health constructs. The concept of health capacity development is a theoretical model of how health capacities, the health-related developmental sociocultural resources individuals use to regulate their coactions with their environments to sustain health, develop. Health capacities are formed through person-environment transactions and thus, are informed by, and help individuals manage, the opportunities and constraints situated in their environments. The extent to which health capacities support long-term adaptive health development varies; yet, health capacities may be leveraged for adaptative functioning. Grounded in the Life Course Health Development (LCHD) framework and the principles of Relational Developmental Systems (RDS) metatheory, the development of three health capacities, their role in managing person-environment coactions, and their potential for facilitating displays of resilient functioning in inequitable contexts are described. Implications of the model, its limitations, and avenues for future research are discussed.

Commentary: The Problems of Grouping All Adversity Into a Special Populations Label

"Special populations" refer to groups of people whose needs are not fully addressed by traditional health services delivery. Greater access to these services, or tailored services, must be provided to reduce inequities in physical and mental health-care systems. Many different groups have been identified as special populations. We comment on controversies regarding the use of the term special populations in health practice and policy. Applicable conceptual issues include intersectionality, unitization, definitional drawbacks, and looping effects. There is a need to make clear the challenges posed by use of this term (e.g., discrimination, workability). An approach that acknowledges the diversity of groups and accommodates them where necessary without discrimination and unequal treatment is needed.

Race and nutrition in the New World: Colonial shadows in the age of epigenetics

This paper addresses historical dimensions of epigenetic studies on human populations. We show that postgenomic research on health disparities in Latin America reintroduces old colonial views about the relations between race, environment, and social status. This especially refers to the idea - common in colonial humoralism and epigenetics - that different types of bodies are in balance and closely linked with particular local environments and lifestyles. These social differences become embodied as physiological and health differences. By comparing Spanish chronicles of the New World with recent epidemiological narratives on Mexican populations in social epigenetics (especially on obesity), we identify four characteristics that both share in distinguishing races, such as indigenous or mestizos from Spaniards or non-Mexicans: (i) Race is not intrinsic to bodies but emerges as a particular homeostatic body-environment relation; (ii) the stability of one's race is warranted through the stability of one's local environment and lifestyle, especially nutrition; (iii) every race faces specific life challenges in a local environment to maintain its health; and (iv) every race shows a unique social status that is closely linked to its biological status (e.g., disease susceptibility). Based on these similarities, we argue that currently in Latin America the field of epigenetics appears on the scene with a worrisome colonial shadow. It reintroduces long forgotten exclusionary and stereotypic perspectives on indigenous and mestizos, and biologizes as well as racializes social-cultural differences among human groups.

Bringing the Real World Into Developmental Science: A Commentary on Weber, Fernald, and Diop (2017)

This article examines the parent intervention program evaluated by Weber et al. (2017) and argues that there are scientific and ethical problems with such intervention efforts in applied developmental science. Scientifically, these programs rely on data from a small and narrow sample of the world's population; assume the existence of fixed developmental pathways; and pit scientific knowledge against indigenous knowledge. The authors question the critical role of talk as solely providing the rich cognitive stimulation important to school success, and the critical role of primary caregivers as teachers of children's verbal competency. Ethically, these programs do not sufficiently explore how an intervention in one aspect of child care will affect the community's culturally organized patterns of child care.

An Epigenetic Prism to Norms and Values

In this article, we ask to what extent the specific characteristics of epigenetics may affect the type of questions one can ask about human society. We pay particular attention to the way epigenetic research stirs debate about normative and moral issues. Are these issues implied by scientific evidence as an outcome of research? Or do moral and normative issues also shape how research is done and which problems it addresses? We briefly explore these questions through examples and discussions in (social-) scientific literature. In the final section, we propose an additional dimension and a refocusing of attention from issues of scientific evidence alone (asking what kind of evidence epigenetics produces and how it does so) to a broader picture on epigenetics as a mode of attention that encourages relational and process-oriented thinking with entities, values and scales that may not yet fit within conventional problem-frames that inform research funding and policy-making. We argue that the task of (post-)ELSI approaches is to take inspiration from the ecological complexity of epigenetics in order to bring more relations, relief and gradient in our ethical and political questions.

Disentangling life: Darwin, selectionism, and the postgenomic return of the environment

In this paper, I analyze the disruptive impact of Darwinian selectionism for the century-long tradition in which the environment had a direct causative role in shaping an organism's traits. In the case of humans, the surrounding environment often determined not only the physical, but also the mental and moral features of individuals and whole populations. With its apparatus of indirect effects, random variations, and a much less harmonious view of nature and adaptation, Darwinian selectionism severed the deep imbrication of organism and milieu posited by these traditional environmentalist models. This move had radical implications well beyond strictly biological debates. In my essay, I discuss the problematization of the moral idiom of environmentalism by William James and August Weismann who adopted a selectionist view of the development of mental faculties. These debates show the complex moral discourse associated with the environmentalist-selectionist dilemma. They also well illustrate how the moral reverberations of selectionism went well beyond the stereotyped associations with biological fatalism or passivity of the organism. Rereading them today may be helpful as a genealogical guide to the complex ethical quandaries unfolding in the current postgenomic scenario in which a revival of new environmentalist themes is taking place.
