| Open AccessThe genetic legacy of the expansion of Bantu-speaking peoples in Africa
We gathered genetic data for 1,763 individuals from 147 populations across 14 African countries, and 12 Late Iron Age individuals, to trace the expansion of Bantu-speaking peoples over the past 6,000 years.

Archaeogenetic study of ancient DNA from medieval northwestern Europeans reveals substantial increase of continental northern European ancestry in Britain, suggesting mass migration across the North Sea during the Early Middle Ages.

| Open AccessTriangulation supports agricultural spread of the Transeurasian languages
A ‘triangulation’ approach combining linguistics, archaeology and genetics suggests that the origin and spread of Transeurasian family of languages can be traced back to early millet farmers in Neolithic North East Asia.

Innovative Homo sapiens behaviours 105,000 years ago in a wetter Kalahari
Human populations in the southern Africa interior were collecting non-utilitarian objects at around 105,000 years ago, suggesting that the development of this innovative behaviour did not depend on exploiting coastal resources.

Information gerrymandering and undemocratic decisions
In a voter game, information gerrymandering can sway the outcome of the vote towards one party, even when both parties have equal sizes and each player has the same influence; and this effect can be exaggerated by strategically placed zealots or automated bots.

Credibility-enhancing displays promote the provision of non-normative public goods
A field study and three experiments demonstrate that people who engage in rare (non-normative) prosocial behaviours will be more effective advocates for those behaviours than people who merely praise the virtues of these prosocial behaviours.

Post-invasion demography of prehistoric humans in South America
South America was the last habitable continent to be colonized by humans; using a database of 1,147 archaeological sites and 5,464 radiocarbon dates spanning 14,000 to 2,000 years ago reveals two phases of the population history of the continent—a rapid expansion through the continent at low population sizes for over 8,000 years and then a second phase of sedentary lifestyle and exponential population growth starting around 5,000 years ago.

Ritual human sacrifice promoted and sustained the evolution of stratified societies
Phylogenetic methods were applied to a cross-cultural database of traditional Austronesian societies to test the link between ritual human sacrifice and the origins of social hierarchy—the presence of sacrifice in a society stabilized social stratification and promoted inherited class systems.

Moralistic gods, supernatural punishment and the expansion of human sociality
Using economic games, the authors examine the role of religion in the persistence of human cooperation; individuals who claim that their gods are moralizing, punitive and knowledgeable about human affairs are more likely to play fairly towards geographically distant co-religionists.

The ontogeny of fairness in seven societies
An analysis of when children develop a sense of fairness (receiving less or more than a peer) is compared across seven different societies; aversion to receiving less emerges early in childhood in all societies, whereas aversion to receiving more emerges later in childhood and only in three of the seven societies studied.

Inequality and visibility of wealth in experimental social networks
Wealth inequality and wealth visibility can potentially affect overall levels of cooperation and economic success, and an online experiment was used to test how these factors interact; wealth inequality by itself did not substantially damage overall cooperation or overall wealth, but making wealth levels visible had a detrimental effect on social welfare.

Business culture and dishonesty in the banking industry
According to popular opinion, unethical business practices are common in the financial industry; here, the employees of a large, international bank are shown to behave, on average, honestly in a laboratory game to reveal dishonest behaviour, but when their professional identity as bank employees was rendered salient, the prevalence of dishonest behaviour increased.

Experimental evidence for the influence of group size on cultural complexity
A dual-task computer game played by groups of different sizes is used to show that cultural evolution (the maintenance or improvement of cultural knowledge) strongly depends on population size; in larger groups of players, higher cultural complexity and cultural trait diversity are maintained, and improvements to existing cultural traits are more frequent.
