Take a break at lunch and learn about chimpanzee communication and relationships with Leakey Foundation grantee, Tufts University biologist, and director of the Kibale Chimpanzee Project Zarin Machanda. Zarin Machanda's research revolves around understanding the factors that shape the quality and development of social relationships among wild chimpanzees. Her work so far has focused mostly on the evolution of male-female relationships, male-male cooperation (especially cooperative hunting), and how chimpanzees use communication to mediate social relationships. Most recently, she has started a long-term project to study infant and juvenile chimpanzees and how they develop sex-typed adult behaviors. Zarin is the Director of Long-term Research at the Kibale Chimpanzee Project, an organization that for the last 30 years has conserved and protected the Kanyawara community of chimpanzees living in Kibale National Park, Uganda.
