Tube rempli de beurre de cacahuète donné à une femelle adulte babouin

Tube filled with peanut butter given to an adult female baboon. The baboon then manipulates this tube with both hands to remove the food. This experiment is used to measure the baboons’ manual preferences. It demonstrated that they are predominantly right-handed, in the order of 61%. These baboons live in an enclosure near Rousset, in the Bouches-du-Rhône (France).
