Chimpanzees have their own language — and scientists just learned how they put "words" together
Few animals appear to be able to communicate with a range as complex and intricate as humans. Those language skills may exist in a limited capacity in our nearest evolutionary neighbors, the great apes, many of whom have been trained to communicate via sign language by human researchers. Yet while sign language is communicated physically, researchers did not believe that great apes possessed their own comparable, complex spoken language.
