Ancient stone tools have been discovered on an island near where the Indonesian "hobbits" were found, suggesting that another group of early humans may have lived in the area around 1 to 1.5 million years ago. The discovery sheds new light on the region's human history, but the identity of these early humans remains a mystery. The find may also have implications for the understanding of the "hobbits" themselves, although the exact nature of these implications is not clear.
