Toshisada Nishida
About
Toshisada Nishida was a Japanese primatologist who established one of the first long term chimpanzee field research sites. He was the first to discover that chimpanzees, instead of forming nuclear family-like arrangements, live a communal life with territorial boundaries. His discoveries of the medicinal use of plants by wild chimpanzees helped form the basis of the field of zoopharmacognosy.
