  1. ncbi request reprint Evolution in the social brain
    R I M Dunbar
    British Academy Centenary Research Project, School of Biological Sciences, University of Liverpool, Liverpool L69 7ZB, UK
    Science 317:1344-7. 2007
    ..This may explain why primate sociality seems to be so different from that found in most other birds and mammals: Primate sociality is based on bonded relationships of a kind that are found only in pairbonds in other taxa...
  2. pmc The evolution of the social brain: anthropoid primates contrast with other vertebrates
    Susanne Shultz
    British Academy Centenary Research Project, School of Biological Sciences, University of Liverpool, Liverpool, UK

    Philos Trans R Soc Lond B Biol Sci 362:649-58. 2007
    ..Finally, we consider the wider issue of how mammalian (and primate) brains evolve in order to localize the social effects...

    R I M Dunbar
    British Academy Centenary Research Project, Institute of Cognitive and Evolutionary Anthropology, University of Oxford, 64 Banbury Road, Oxford OX2 6PN, UK

    Susanne Shultz
    British Academy Centenary Research Project, School of Biological Sciences, University of Liverpool, Liverpool L69 7ZB, UK
    Biol Lett 2:505-8. 2006
    ..Thus, we provide evidence for the hypothesis that brain size evolution is potentially driven by selection for more sophisticated and behaviourally flexible anti-predator strategies...

    Susanne Shultz
    School of Biological Sciences, University of Liverpool, Biosciences Building, Crown Street, Liverpool L69 7ZB, UK

    R I M Dunbar
    British Academy Centenary Research Project, University of Oxford, Oxford, UK
    Proc Biol Sci 279:1161-7. 2012
    ..This pain-tolerance effect is due to laughter itself and not simply due to a change in positive affect. We suggest that laughter, through an endorphin-mediated opiate effect, may play a crucial role in social bonding...

    Proc Biol Sci 271:725-32. 2004
    ..These results reveal that it is necessary to consider anti-predator strategies in the context of a dynamic behavioural interaction between predators and prey...
  13. pmc Discrete hierarchical organization of social group sizes
    W X Zhou
    State Key Laboratory of Chemical Reaction Engineering, East China University of Science and Technology, Shanghai 200237, China
    Proc Biol Sci 272:439-44. 2005
    ..Such discrete scale invariance could be related to that identified in signatures of herding behaviour in financial markets and might reflect a hierarchical processing of social nearness by human brains...
