Discuss the implications of the discovery of Chauvet Cave’s naturalistic depictions of animals

Please provide the best answer for the statement.

The ideal response would include the following:
Before the discovery of Chauvet, historians divided the history of cave painting into a series of successive styles, each progressively more realistic. But Chauvet’s paintings, by far the oldest known, are also the most advanced in their visual naturalism.
Art historians now tend to agree that, even from the earliest times, human beings chose to represent the world naturalistically or not, with the choice representing not lack of skill or sophistication but expressive intent or cultural values.
This upsetting of earlier assumptions about linear progression in sophistication suggests that we question our assumptions when we are inclined to equate earlier cultures with more primitive values and skills.
