Generalization Increases the Adaptive Value of Mate Choice Copying When Immediate Copying Is Costly
When assessing potential mates is costly, there will be selection for copying others. Mate choice copying, which is the increased chance of mating with another individual after observing them mating with someone else (i.e., individual-based copying), has been documented in several species, including humans. It is touted as an example of the influence of culture on animal and human mating, but alone it is unlikely to lead the cultural evolution of…
Pregnancy outcomes among evacuees of the Sinabung volcano, 2010–2018 (North Sumatra, Indonesia): A matched cohort study
OBJECTIVES: Exposure to natural disasters during pregnancy is associated with adverse birth outcomes and increased probability of female births. Nonetheless, relatively little work has been done on evacuations of women living in close vicinity to volcanic eruptions. We conducted a retrospective cohort study among women from villages near the Sinabung volcano in North Sumatra, Indonesia, which has been active since 2010. METHODS: We compared an "e…

Kinship intensity and the use of mental states in moral judgment across societies
Olfactory predator recognition in the brown mouse lemur ( Microcebus rufus ) in Ranomafana National Park, Madagascar
Predator odors such as urine and feces are known to elicit antipredator behaviors in prey including avoidance, fear, and curiosity. We measured how wild brown mouse lemurs ( Microcebus rufus ) responded to odors of mammalian, avian, and snake predators as well as nonpredator controls. The first experiment took place under controlled conditions in a laboratory where we recorded the occurrence of four behavioral categories (ignore, curiosity, alert…

Female status, food security, and stature sexual dimorphism: Testing mate choice as a mechanism in human self‐domestication
OBJECTIVES: Humans exhibit multiple anatomical and behavioral signatures of domestication syndrome, leading evolutionary-minded scholars to suggest Homo sapiens is a "self-domesticated" species. We examined one of three mechanisms proposed to explain human self-domestication-that is, intersexual selection against reactive aggression. We hypothesized that this process has been, at least in part, caused by context-dependent female preferences for l…
Ecology of Pair-Bond Stability
Small-scale societies exhibit fundamental variation in the role of intentions in moral judgment
Significance It is widely considered a universal feature of human moral psychology that reasons for actions are taken into account in most moral judgments. However, most evidence for this moral intent hypothesis comes from large-scale industrialized societies. We used a standardized methodology to test the moral intent hypothesis across eight traditional small-scale societies (ranging from hunter-gatherer to pastoralist to horticulturalist) and t…

Helper effects on breeder allocations to direct care
INTRODUCTION: Mothers receive childcare and productive assistance from allomaternal helpers in many societies. Although much effort has been aimed toward showing helper effects on maternal reproductive success, less has been directed toward highlighting the full range of potential effects on breeder behavior. I present a model of optimal maternal care with helpers, and tests of derived hypotheses with data collected among the Karo Batak-a group o…

Karo Batak Cousin Marriage, Cosocialization, and the Westermarck Hypothesis
Among the Karo Batak of North Sumatra, Indonesia, marriages between matrilateral cross cousins (impal) are the ideal, yet rarely occur. Further, ethnographic accounts reveal a stated aversion to impal marriage. These observations are consistent with Westermarck's "negative imprinting" hypothesis if impal are cosocialized. We present analyses of postmarital residence patterns from two studies of the Karo Batak. The analyses reveal that although in…
Resource Competition and Reproduction in Karo Batak Villages
Parental Supply and Offspring Demand Amongst Karo Batak Mothers and Children
The resolution of parent–offspring conflict (POC) might sway in favour of the offspring if the parent relies on offspring-supplied information about need. Here, three hypotheses from a resolution model of POC were tested using data on sickness histories and mother–infant interactions from 24 Karo Batak women and their young children from two rural villages in North Sumatra, Indonesia. First, as predicted, offspring with greater need (measured as …
