What evidence is there for language use among early hominids?

Evidence for language use among early hominids includes the presence of a descended larynx, which is important for producing a wide range of vocal sounds, as well as the discovery of symbolic artifacts like cave paintings and figurines. Additionally, studies of the brain structure of early hominids suggest an increased capacity for language processing. Archaeological findings of complex tools and evidence of social cooperation also support the idea that early hominids likely communicated through some form of language.
