Human large-scale cooperation as a product of competition between cultural groups
Nature Communications, 2020 The authors here show that readiness to cooperate between individuals from different groups corresponds to the degree of cultural similarity between those groups.

Frontiers in Ecology and Evolution, 2022 The buff-tailed bumblebee Bombus terrestris presents two distinct colony phenotypes in which some colonies already start producing males very early in the season, while others switch to producing sexuals much later in the season, and specialize mainly in

Social dilemmas in an online social network: the structure and evolution of cooperation [PDF]
, 2007 We investigate two paradigms for studying the evolution of cooperation--Prisoner's Dilemma and Snowdrift game in an online friendship network obtained from a social networking site.

Social evolution in mammals [PDF]
Science, 2021 Mammal societies Although a few types of structures prevail, social systems among mammals are relatively varied. New techniques, from monitoring to genetics, have allowed for a deeper understanding of this variation, how it is related to the environment, and how it has evolved.

Dental Anthropology, 2006 Described are observations on Batak foods, tooth use, oral hygiene, and resulting wear and oral pathology in dental casts of 29 Batak ranging from 15 to 49 years of age. Commonly consumed foods are roughly 80 percent plant, and 20 percent animal products.

Frontiers in Ecology and Evolution, 2022 The social mole-rats of the family Bathyergidae show elaborate social organisation that may include division of labour between breeders and non-breeders as well as across non-breeders within their groups.

Sociality, Evolution and Cognition [PDF]
Current Biology, 2007 Variations in brain size and proportions can be linked to the cognitive capacities of different animal species, and correlations with ecology may give clues to the evolutionary origins of these specializations. Much recent evidence has implicated the social domain as a major challenge driving increases in problem-solving abilities of mammals.

Morphological and population genomic evidence that human faces have evolved to signal individual identity. [PDF]
, 2014 Facial recognition plays a key role in human interactions, and there has been great interest in understanding the evolution of human abilities for individual recognition and tracking social relationships.

Evolving Social Networks via Friend Recommendations
, 2015 A social network grows over a period of time with the formation of new connections and relations. In recent years we have witnessed a massive growth of online social networks like Facebook, Twitter etc. So it has become a problem of extreme importance to

Uncertainty about social interactions leads to the evolution of social heuristics
Nature Communications, 2018 Humans are known to use social heuristics to make intuitive decisions on whether to cooperate. Here, the authors show with evolutionary simulations that social heuristics can be an adaptive solution to uncertainties about the consequences of cooperation ...
