Sign language in primates

Sign language in primates refers to the use of manual gesturing as a form of communication among certain species, particularly in experiments with apes and monkeys. Researchers have taught primates like chimpanzees and gorillas to use signs or symbols to express needs, thoughts, or emotions, similar to how humans use sign language. These studies aim to understand cognitive abilities and social interactions in primates, revealing their capacity for language-like communication. While not as complex as human language, these forms of communication demonstrate that primates possess the ability to convey meaningful messages through gestures.
