I’m sure the thinking is that art appearing in both Europe and Indonesia suggests that they both inherited it from their common ancestors in Africa.
But when the earliest art was thought to have been European, the idea that art originated in Europe and spread from there via cultural diffusion was considered a reasonable hypothesis. Now that earlier art has been found outside Europe, the flip scenario—that art spread from Indonesia to Europe via cultural diffusion instead of shared ancestry—isn’t even mentioned.
