Kin terms and fitness interdependence
Publication date: Available online 22 December 2018Source: Evolution and Human BehaviorAuthor(s): Dieter Steklis, Netzin Steklis, Olmo van den Akker, Athena Aktipis, Lee CronkAbstractAlthough genetic relatedness has been shown to be an important determinant of helping and other forms of cooperation among kin, it does not correspond well to the different types of kin designated by the kin terminologies used in human societies. This mismatch between genetic relatedness and kin terms has led some anthropologists to reject the idea that kin terms have anything to do with genetic relatedness or anything else biological. The evo...

Who punishes promiscuous women? Both women and women, but only women inflict costly punishment
Publication date: Available online 22 December 2018Source: Evolution and Human BehaviorAuthor(s): Naomi K. Muggleton, Sarah R. Tarran, Corey L. FincherAbstractAcross human societies, female sexuality is suppressed by gendered double standards, s. shaming, sexist rape laws, and honour killings. The question of what motivates societies to punish promiscuous women, however, has been contested. Although some have argued that men suppress female sexuality to increase paternity certainty, others maintain that this is an example of intrasexual competition. Here we show that both sexes are averse to overt displays of female sexual...

Common marmosets are sensitive to simple dependencies at variable distances in an artificial grammar
Publication date: Available online 1 December 2018Source: Evolution and Human BehaviorAuthor(s): Stephan A. Reber, Vedrana Šlipogor, Jinook Oh, Andrea Ravignani, Marisa Hoeschele, Thomas Bugnyar, W. Tecumseh FitchAbstractRecognizing that two elements within a sequence of variable length depend on each other is a key ability in understanding the structure of language and music. Perception of such interdependencies has previously been documented in chimpanzees in the visual domain and in human infants and common squirrel monkeys with auditory playback experiments, but it remains unclear whether it typifies primates in gener...

High consanguinity promotes intergenerational wealth concentration in socioeconomically privileged Krummhörn families of the 18th and 19th centuries
Publication date: Available online 1 December 2018Source: Evolution and Human BehaviorAuthor(s): Johannes Johowa, Kai P. Willführ, Eckart VolanddAbstractPrevious research has demonstrated that consanguineous marriage is a vector for socioeconomic inheritance and for the maintenance of family structure and property. On the basis of reconstituted families from the Krummhörn, Ostfriesland in the 18th and 19th centuries, we examine statistical correlations between ascertained inbreeding coefficients (F) based on family trees and socioeconomic status as well as the intergenerational transmission of landholdings. Semiparametri...

Explaining marriage patterns in a globally representative sample through socio-ecology and population history: A Bayesian phylogenetic analysis using a new supertree of human cultures
Publication date: Available online 15 November 2018Source: Evolution and Human BehaviorAuthor(s): Riana Minocher, Pavel Duda, Adrian V. JaeggiAbstractComparative analyses have sought to explain variation in human marriage patterns, often using predictions derived from sexual selection theory. However, most previous studies did not control for non-independence of populations due to shared ancestry. Here we leverage a phylogenetic supertree of human populations that includes all 186 populations in the Standard Cross-Cultural Sample (SCCS), a globally representative and widely-used sample of human populations. This represents...

Whether to have a second child or not? An integrative approach to women's reproductive decision-making in current China
Publication date: Available online 12 November 2018Source: Evolution and Human BehaviorAuthor(s): Jianghua Liu, Virpi LummaaAbstractThe transition to low fertility worldwide has led to introduction of diverse frameworks across disciplines to understand its causes and consequences. Previous attempts to compare the relative importance of the key factors influencing women's fertility decision-making largely focused on a single rather than multiple steps of decision-making—an important problem if different factors are associated with different steps. Furthermore, insufficient attention has been paid explicitly to husband's a...

The amplifying role of need in giving decisions
Publication date: Available online 8 November 2018Source: Evolution and Human BehaviorAuthor(s): Alexander F. Danvers, Joseph V. Hackman, Daniel J. HruschkaAbstractHamilton's rule predicts that altruism should depend on costs incurred and benefits provided, but these depend on the relative needs of the donor and recipient. Rewriting Hamilton's rule to account for relative need suggests an amplifying effect of need on relatedness, but not necessarily other relationship qualities. In a reanalysis of three studies of social discounting and a new replication, we find that relative need amplifies the effects of relatedness on g...

Sociosexuality, Testosterone, and Life history Status: prospective Associations and Longitudinal changes among men in Cebu, Philippines
Publication date: Available online 7 November 2018Source: Evolution and Human BehaviorAuthor(s): Lee T. Gettler, Patty X. Kuo, Stacy Rosenbaum, Josephine L. Avila, Thomas W. McDade, Christopher W. KuzawaAbstractSociosexuality is defined as an individual's interest in uncommitted sexual activity and can be measured in terms of both psychological orientations and behavioral expression. In socio-ecological contexts in which adults monogamously partner and cooperate to raise children, individuals with unrestricted sociosexuality are likely to prioritize mating/competition over committed partnering and parenting. Given the impo...

Emotion makes a difference: Induced sadness reduces preschool boys' sharing behavior
This study investigated how external negative emotional stimuli influenced 5–6-year-old children's (N = 98) sharing behavior. Children were asked to watch a video that induced either sad or neutral emotion and then share stickers simultaneously with poor and wealthy recipients. Compared to the neutral emotion condition, boys shared less, and offered more self-focused reasons for sharing after being induced sad emotions; girls however, shared equally, and provided self-focused and other-focused reasons equally in both emotional conditions. Results indicated that sadness increased children's tendency to defend their ow...

No evidence that facial attractiveness, femininity, averageness, or coloration are cues to susceptibility to infectious illnesses in a university sample of young adult women
Publication date: Available online 24 October 2018Source: Evolution and Human BehaviorAuthor(s): Ziyi Cai, Amanda C. Hahn, Weiqing Zhang, Iris J. Holzleitner, Anthony J. Lee, Lisa M. DeBruine, Benedict C. JonesAbstractPrevious reports that women with attractive faces are healthier have been widely cited as evidence that sexual selection has shaped human mate preferences. However, evidence for correlations between women's physical health and facial attractiveness is equivocal. Moreover, positive results on this issue have generally come from studies of self-reported health in small samples. The current study took standardiz...
