Do humans prefer altruistic mates? Testing a link between sexual selection and altruism towards non-relatives (2008)
Journal Article
Phillips, T., Barnard, C., Ferguson, E., & Reader, T. (2008). Do humans prefer altruistic mates? Testing a link between sexual selection and altruism towards non-relatives. British Journal of Psychology, 99(4), 555-572. https://doi.org/10.1348/000712608X298467

Humans are often seen as unusual in displaying altruistic behaviour towards nonrelatives. Here we outline and test a hypothesis that human altruistic traits evolved as a result of sexual selection. We develop a psychometric scale to measure mate pref... Read More about Do humans prefer altruistic mates? Testing a link between sexual selection and altruism towards non-relatives.
