A team of researchers from the CNRS Institute of Cognitive Sciences at University Claude Bernard in Lyon, France, and the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany, has for the first time identified distinct mother-offspring attachment types in wild chimpanzees (Pan troglodytes verus) in Taï National Park, Côte d'Ivoire. Drawing parallels with human psychology, the study provides compelling evidence that wild chimpanzee infants, like human children, develop critical secure and insecure-avoidant attachment patterns to their mothers. However, unlike humans and some captive chimpanzees, wild chimpanzees did not exhibit disorganised attachment characterised by high rates of aggression. This raises new questions about how this type of attachment may be shaped by survival and modern environmental pressures.
