Department of Anthropology, University of California Los Angeles, Los Angeles, California 90095, USA
Curr Biol 17:R50-1. 2007..Conflict is a fact of life in social species. New data from birds enhance our understanding of how and why evolution has favored mechanisms to resolve disputes and manage conflicts... - Behavior. Who are more helpful, humans or chimpanzees?Joan B Silk

Department of Anthropology, University of California, Los Angeles, CA 90095, USA
Proc Biol Sci 272:859-64. 2005..The results do not support predictions derived from either model of facultative sex ratio adjustment, and we conclude that there is currently no evidence that baboon birth sex ratios are adjusted in an adaptive manner... - Social bonds of female baboons enhance infant survivalJoan B Silk
Department of Anthropology, University of California, Los Angeles UCLA, CA 90095, USA
Science 302:1231-4. 2003..Our results are consistent with the evidence that social support has beneficial effects on human health and well-being across the life span.

Department of Anthropology, University of California, Los Angeles, CA, USA
Philos Trans R Soc Lond B Biol Sci 364:3243-54. 2009..There are good reasons to suspect that these processes may complement the effects of kin selection and amplify the extent of nepotistic biases in behaviour... 
Strong and consistent social bonds enhance the longevity of female baboonsJoan B Silk
Department of Anthropology, University of California Los Angeles, CA 90095, USA
Curr Biol 20:1359-61. 2010..These data extend our understanding of the adaptive value of social bonds in baboons and complement a growing body of evidence that indicates that social bonds have adaptive value in a range of taxa, from mice to humans [9, 14-19]...- Male chimpanzees exchange political support for mating opportunitiesKimberly G Duffy
Department of Anthropology, University of California at Los Angeles, Los Angeles, CA 90095, USA

Department of Biology, Duke University, Box 90338, Durham, North Carolina 27708, USA
Nature 425:179-81. 2003..As support in agonistic disputes is likely to contribute to rank acquisition and protect juveniles from injury and stress, this can be considered true parental care... - Reconsidering the null hypothesis: Is maternal rank associated with birth sex ratios in primate groups?Gillian R Brown
Sub Department of Animal Behaviour, Department of Zoology, University of Cambridge, Madingley, Cambridge CB3 8AA, United Kingdom
Proc Natl Acad Sci U S A 99:11252-5. 2002..These findings indicate that presently we cannot reject the null hypothesis that maternal dominance rank is unrelated to birth sex ratios...
