The self-domestication hypothesis (SDH) suggests bonobo psychology evolved due to selection against aggression and in favour of prosociality. This hypothesis was formulated based on similarities between bonobos and domesticated animals. This chapter reviews the first generation of quantitative research that supports the predictions of the SDH. Similar to domestic animals, bonobos are prosocial towards strangers, more flexible with cooperative problems, more responsive to social cues and show expanded windows of development relative to their closest relatives, chimpanzees. A preliminary comparison of bonobo and chimpanzee infants is presented that suggests that when hearing a stranger, bonobos have a xenophilic response while chimpanzees have a xenophobic response. The chapter explores why the work with bonobos has implications for theories of both human and animal cognitive evolution, and why bonobos will be central in studying evolutionary processes leading to cognitive change. L’hypothèse d’auto-domestication (SDH) suggère que la psychologie bonobo a évolué grâce à la sélection contre l’agression et en faveur de la prosocialité. Cette hypothèse fut formulée à partir de similarités entres les bonobos et les animaux domestiqués. Nous révisons la première génération de recherche quantitative qui soutient les prédictions du SDH. Comme les animaux domestiques, les bonobos sont prosociaux envers les étrangers, plus flexibles avec les problèmes de coopération, plus sensibles aux signaux sociaux, et montrent des fenêtres étendues de développement relativement à leur plus proche parent, le chimpanzé. Nous présentons une comparaison préliminaire des bébés bonobos et chimpanzés. Quand ils entendent un étranger, les bonobos ont une réaction xénophilique alors que les chimpanzés ont une réaction xénophobique. Nous expliquons pourquoi le travail des bonobos est impliqué dans les théories d’évolution cognitive humaine et animale, et pourquoi les bonobos seront au centre des études évolutionnaires des procès menants aux changements cognitives.
