To celebrate the 60th anniversary of the Japan Monkey Centre in 2016, we established a new annual prize: Primates Social Impact Award. Please read the announcement with the original video provided by the first winner showing the behaviors of chimpanzees.

Primates is an international journal of primatology whose aim is to provide a forum for the elucidation of all aspects of primates. The oldest primatological journal, Primates publishes original papers that advance the scientific study of primates, and its scope embraces work in diverse fields covering biological bases of behavior, socio-ecology, learning and cognition, social processes, systematics, evolution, and medicine. Contributions relevant to conservation of natural populations and welfare of captive primates are welcome. Studies focusing on nonprimate species may be considered if their relevance to primatology is clear. Original Articles as well as Review Articles, News and Perspectives, and Book Reviews are included. All manuscripts received are initially screened for suitability by members of the Editorial Board, taking into account style and ethical issues, leading to a swift decision about whether to send the manuscript for external review.

The Editor-in-Chief is Tetsuro Matsuzawa, Kyoto University.

Color figures are free in print and online

No publication charge for authors

The new cover of Primates features a young female chimpanzee named Joya using a pair of stones as a tool to crack open an oil-palm Nut. Photo taken by Anup Shah and Fiona Rogers in Bossou, Guinea.

She was born on September 2nd, 2004, and this event occurred in December 2010, when she was 6 years and 3 months old. The chimpanzees of Bossou use a pair of stones as a hammer and anvil to crack open the hard shell of the oil-palm nut to get at the soft, edible part within, the kernel. This is a cultural behavior unique to this community and is transmitted socially from one generation to the next. The chimpanzees acquire the skill at around 4–5 years old. The learning process involved is called ‘‘Education by Master-apprenticeship’’ (Matsuzawa et al., 2001).
