Final answer:
Neanderthals displayed evidence of culture through their use of tools, language, and symbolic behavior.
Step-by-step explanation:
Neanderthals displayed evidence of culture through their use of tools, language, and symbolic behavior. The Neanderthals' tool industry, known as the Mousterian tool industry, was more technologically advanced than that of previous hominins. They created flake tools by striking flakes from cores, resulting in smaller and sharper tools.
While there is still debate about the extent of Neanderthal language, archaeological evidence suggests that they had the cognitive abilities necessary for language. Language likely emerged as part of a complex set of social and cognitive skills, similar to the abilities required for tool making.
Neanderthals also engaged in symbolic behavior, as seen in the burial of their dead, the creation of art, and the use of pigments for body ornamentation. These behaviors indicate the presence of a cultural and symbolic system.
