Chimpanzee cultures are mainly constituted of tool-using behaviors. For instance, communities in West Africa crack nuts with stones, while chimpanzees in Central Africa use several sticks in a row to access bee nests. In the Ugandan community of Sonso (Pan troglodytes schweinfurthii), none of these behaviors are present. Despite their small toolkit, the Sonso chimpanzees recently started displaying a novel behavior, moss-sponging (manufacturing a sponge from moss to drink water, pictured), adapted from their existing knowledge. Network-based analysis showed that this behavior spread through social learning, solving a long-lasting controversy in the chimpanzee culture debate, namely, whether chimpanzees exhibit social transmission of new behaviors or not. See Hobaiter et al.
