Episode 52: How to Study an Endangered Species

What is it like to study an endangered species like chimpanzees, knowing they may go extinct within your lifetime?

Leakey Foundation grantee Dr. Zarin Machanda is a co-director of the Kibale Chimpanzee Project, a long-term field study in Uganda. This study was started by primatologist Richard Wrangham in 1987, and project members have collected daily records of the chimps there ever since.

These notes hold the life stories of around 150 chimpanzees, and this long-term data is a powerful way for scientists to understand chimpanzees–and ourselves.

Support Long-Term Field Research

The Leakey Foundation’s Primate Research Fund helps keep long-term primate studies going no matter what. We provide emergency funding to projects facing a gap in their usual funding - or other emergencies that threaten their ability to collect data.

During the pandemic we have had more applications than ever so we need your help. We are trying to raise a total of $25,000 for this fund. Every donation up to that total amount will be quadruple-matched. Any amount helps! Click here to learn more and donate.

Why are humans the way we are? One way to answer this question is to look to our closest cousins, the chimpanzees. Join Assistant Professor of Psychology and Anthropology Alexandra Rosati of the University of Michigan and Assistant Professor of Anthropology and Biology Zarin Machanda of Tufts University as they examine the world of chimpanzees, including chimpanzee social lives, ecological context, and how they think and solve problems.
