Boom-boom-krak-oo – Campbell’s monkeys combine just six ‘words’ into rich vocabulary
Many human languages achieve great diversity by combining basic words into compound ones – German is a classic example of this. We’re not the only species that does this. Campbell’s monkeys have just six basic types of calls but they have combined them into one of the richest and most sophisticated of animal vocabularies.
