Chimpanzees Show Grooming Handclasp (2 of 2) (VIDEO)

Max-Planck-Gesellschaft

Caption

At the beginning of the video two chimpanzees engage in the palm-to-palm handclasp with their left arms, then transition to the same style with their right arms. About a minute and a half later, two chimpanzees near the building start handclasping in the same palm-to-palm style. This is Zsabu (the alpha male) and Noel. Palm-to-palm is the most frequently used style in this community.
