Which Paleolithic cave painting site prompted scholars to change their understanding of prehistoric art?

Altamira

Chauvet

Lascaux

Peche Merle

The best answer for this question would be:

Peche Merle

Because archaeologists had easily identified the wide skills and variety of the ages of the artists before. The art in the cave had a hypothesis of powerful beasts and men, describing the what kind of era it was in the past.
