The Hajnal Line and Gene-Culture Coevolution in Northwest Europe

North and west of a line running from Trieste to St. Petersburg, social relations have long conformed to the Western European Marriage Pattern, i.e., men and women marry relatively late; many people never marry; children usually leave the nuclear family to form new households, and households often have non-kin members. This pattern goes back at least to the thirteenth century and perhaps to prehistoric times. I argue that this environment of weaker kinship caused northwest Europeans to create communities based on shared moral rules, rather than shared kinship. Community members enforced these rules by monitoring not only the behavior of other members but also their own behavior and even their own thoughts. Initially, this new mindset did not have a genetic basis. Individuals acquired it within the bounds of phenotypic plasticity. Over time, however, a genetic basis would have developed through the survival and reproduction of individuals who were better at being socially independent, at obeying universal rules, at monitoring other community members, and at self-monitoring, self-judging, and self-punishing. These psychological adaptations-independent social orientation, universal rule adherence, affective empathy, guilt proneness-are moderately to highly heritable. Although they are complex, they required only minor evolutionary changes to evolve out of mechanisms that were already present but limited to specific behavioral contexts. Affective empathy, for instance, is a species-wide trait but usually confined to relations with close kin, particularly between a mother and her young children. An evolutionary scenario is proposed, and two questions discussed. Are these mental traits too complex to have evolved over a span of 30 to 300 generations? Are they too altruistic to be sustainable?

The Large Society Problem in Northwest Europe and East Asia

Kinship was the organizing principle of early societies, defining how people should behave toward each other. Social and economic activity was thus organized mostly among closely related individuals, a limitation that would keep societies from realizing their full potential as they grew larger. The "large society problem" has not been fully solved anywhere, but Northwest Europeans and East Asians have gone the farthest toward a solution. In general, the solution has been to weaken the relative importance of kinship and strengthen forms of sociality that can include everyone, and not just close kin. In particular, one must think and feel in certain ways, i.e., be susceptible to social norms that are absolute, universal, and independent of kinship; feel guilty after breaking social norms; feel empathy for non-kin; and orient oneself toward society. This mindset shows similarities and differences between Northwest Europeans and East Asians. Both groups adapted to a larger social environment by becoming more empathetic toward non-kin and more susceptible to universal social norms. Northwest Europeans became more individualistic while acquiring stronger internal controls of behavior (affective empathy, guilt proneness). East Asians became more collectivistic while acquiring stronger internal controls (cognitive empathy) and stronger external controls (shaming, family-community surveillance, inculcation of normative behavior).

“…The search strategy on PubMed and Web of Knowledge identified a total of 128 studies, of which 16 were duplicates. After the removal of 95 hits not fulfilling the inclusion criteria, 17 studies were finally included in the qualitative review of gene association studies focusing on MOH (22)(23)(24)(25)(26)(27)(28)(29)(30)(31)(32)(33)(34)(35)(36)(37)(38). The main characteristics of the identified studies are summarized in Table 1 between 2006 and 2015 by five research groups, four of which were located in Italy -including our group -and one in Japan, with sample sizes of MOH patients ranging from 22 to 227.…”

A systematic review and critical appraisal of gene polymorphism association studies in medication-overuse headache

et al. 2017

Purpose of review Medication-overuse headache is a secondary chronic headache disorder, evolving from an episodic primary headache type, caused by the frequent and excessive use of headache symptomatic drugs. While gene polymorphisms have been deeply investigated as susceptibility factors for migraine, little attention has been paid to medication-overuse headache genetics. In the present study we conducted a systematic review to identify, appraise and summarize the current findings of gene polymorphism association studies in medication-overuse headache. Methods A comprehensive literature search was conducted on PubMed and Web of Knowledge databases of primary studies that met the diagnostic criteria for medication-overuse headache according to the temporally-relevant Classification of Headache Disorder of the International Headache Society. Results A total of 17 candidate gene association studies focusing on medication-overuse headache were finally included in the qualitative review. Among these, 12 studies investigated the role of common gene polymorphisms as risk factors for medication-overuse headache susceptibility, six studies focused on the relationship with clinical features of medication-overuse headache patients, and four studies evaluated their role as determinants of clinical outcomes in medication-overuse headache patients. Conclusion Results of single studies show a potential role of polymorphic variants of the dopaminergic gene system or of other genes related to drug-dependence pathways as susceptibility factors for disease or as determinants of monthly drug consumption, respectively. In this systematic review, we summarize the findings of gene polymorphism association studies in medication-overuse headache and discuss the methodological issues that need to be addressed in the design of future studies.
