Chimpanzees' Decade-Long Stone-Throwing Behavior Studied in Guinea-Bissau
Le lancer de pierres est un comportement rare, possiblement culturel, observé chez quatre groupes de chimpanzés sauvages d’Afrique de l’Ouest. Des scientifiques sont allés les observer en Guinée-Bissau pour déterminer ce que ces animaux tentent de communiquer par ce geste. Deux d’entre elles racontent.
Scientists are investigating a peculiar and persistent behavior observed in four wild chimpanzee groups in West Africa: the throwing of stones at specific trees over more than ten years. This stone-throwing is considered a rare behavior, potentially indicating cultural transmission within the chimpanzee communities. Researchers traveled to Guinea-Bissau to study these chimpanzees and decipher the meaning behind this action. The study aims to understand what the chimpanzees might be communicating through this repeated gesture. Two researchers involved in the project share their experiences and findings. This research could shed light on complex chimpanzee communication and social learning.
