"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. Filmed by researcher Patrick Mwika at Chimfunshi Wildlife Orphanage Trust." From: https://youtu.be/L0JIVNZeP9M |
