Abang the Orangutan makes a stone tool, a film by Dr Richard Wright, ca. 1972

This film of Abang, an Indonesian Orangutang, was made by Dr Richard Wright in the early 1970s to explore the stoneworking capabilities of apes. His work was followed a decade later by the famous experiments with Kanzi, a captive bonobo. Special thanks to Richard for giving us permission to host this historically important video.
