“It was very difficult and quite gruesome to watch,” said Pruetz, a professor of anthropology at Iowa State University. “I couldn’t initially make sense of what was happening, and I didn’t expect them to be so aggressive with the body.”
Pruetz has witnessed many things since establishing her research site in 2001. She was the first to document chimps using tools to hunt prey. However, what she observed in 2013 was different. Pruetz and her research team documented the chimps’ behavior after discovering the body of Foudouko, a former leader of the Fongoli community, who was exiled from the group for five years.
