| Open AccessInferring language dispersal patterns with velocity field estimation
Reconstructing language dispersal patterns is important for understanding cultural spread and demic diffusion. Here, the authors use a computational approach based on velocity field estimation to infer the dispersal patterns of Indo-European, Sino-Tibetan, Bantu, and Arawak language families.

| Open AccessChanges in limiting factors for forager population dynamics in Europe across the last glacial-interglacial transition
Here, the authors use climate and resource availability, to statistically model the limiting factors in the dynamics of hunter-gatherer population densities in Europe between 21,000 and 8,000 years ago. They find that limiting factors varied spatiotemporally and the effects of these may be visible in the archaeological record.

| Open AccessProsociality predicts labor market success around the world
Previous research on the importance of prosociality is based on observations from WEIRD societies, questioning the generalizability of these findings. Here the authors present a global investigation of the relation between prosociality and labor market success and generalize the positive relation to a wide geographical context.

| Open AccessScale and information-processing thresholds in Holocene social evolution
The Seshat database has made it possible to reveal large-scale patterns in human cultural evolution. Here, Shin et al. investigate transitions in social complexity and find alternating thresholds of polity size and information processing required for further sociopolitical development.

| Open AccessClosing the gender gap in competitiveness through priming
Men are often more willing to compete compared to women, which may contribute to gender differences in wages and career advancement. Here, the authors show that ‘power priming’ - encouraging people to imagine themselves in a situation of power - can close the gender gap in competitiveness.

| Open AccessCooperation and the evolution of hunter-gatherer storytelling
Storytelling entails costs in terms of time and effort, yet it is a ubiquitous feature of human society. Here, Smith et al. show benefits of storytelling in Agta hunter-gatherer communities, as storytellers have higher reproductive success and storytelling is associated with higher cooperation in the group.

| Open AccessSocial image concerns promote cooperation more than altruistic punishment
Cooperation requires individuals to sacrifice individual rewards for group benefits. Here, Grimalda, Pondorfer and Tracer show in a foraging society of Papua New Guinea that social image building is a more powerful motivator of social cooperation than altruistic punishment.

| Open AccessDisease dynamics and costly punishment can foster socially imposed monogamy
Many human societies transitioned from polygyny to socially imposed monogamy as group sizes increased. Using a simulation model, the authors show that sexually transmitted infections impose heavier fitness penalties on polygynists as group size grows, enabling monogamists who punish polygyny to thrive in large groups.

| Open AccessCooperation is related to dispersal patterns in Sino-Tibetan populations
Dispersal is key to establishing patterns of cooperation. Here, the authors show that social organization is associated with levels of cooperation in Sino-Tibetan populations with strikingly different dispersal patterns.
