Anja Widdig is a scientist at the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany. Her research focuses on the behavioural and social structures of great apes, particularly chimpanzees and bonobos. She investigates how social relationships, hierarchies and environmental factors influence the behaviour and development of these animals. The aim of her work is to gain insights into the evolution of human behaviour. Her studies contribute to a better understanding of our origins and the development of social structures.
