Observations of savanna chimpanzees (Pan troglodytes verus) at the Fongoli field site in Senegal have changed what and how we think we know about chimpanzees. For instance, chimpanzees were believed to be “water-fearing”, but the Fongoli chimps demonstrate how this is not a trait shared by all of Pan troglodytes. What else can we learn from this unique community of chimps?
