The benefits of sociality: understanding the relationship between cooperation, cognition and fitness

点击翻译按钮获取中文摘要

Cooperation may present unique cognitive challenges. Individuals perform behaviours that provide fitness benefits to others, exposing themselves to risk. The need to monitor the behaviour of group members, recognise suitable cooperative partners, and make corresponding behavioural adjustments to maximize the benefits of cooperation, may therefore be an important driver of social evolution. The relevance of understanding the relationship between cognition and cooperation is in how it affects the fitness of individuals and the stability of cooperation. This project aims to unveil this relationship by conducting one of the first comprehensive studies of the selective benefits of cognitive ability in a wild, cooperative bird species.
