The olive colobus: the hidden grammar of a little-known monkey

How does the olive colobus, a small primate from the Ivorian forests, manage to convey complex messages despite a limited vocal repertoire? A study conducted by the University of Neuchâtel reveals that this discreet monkey combines its two types of calls, "A" and "B", according to precise rules, creating sophisticated communication. A discovery that could shed light on the evolution of linguistic complexity in primates, and perhaps even in humans.
