Adam Brumm

Adam Brumm is not mentioned in any of the provided news articles. The articles focus on the discovery of potentially the world's oldest known rock art: hand stencils found in limestone caves on Muna Island, Indonesia. These stencils are estimated to be up to 67,800 years old. The discovery is newsworthy because it could rewrite the timeline of human creativity and symbolic thought. The handprints were found amongst more recent paintings and had gone unnoticed. The significance lies in the potential to understand the origins of human artistic expression and cognitive development. The research was conducted by Indonesian and Australian researchers, including Adhi Agus Oktaviana.
