Then, some stone tools found on the Indonesian island of Sulawesi predate the arrival of modern humans to the area by more than 60,000 years—but researchers aren’t sure who made them. The perplexing artifacts, announced in Nature magazine, are most likely between 118,000 and 194,000 years old, though some may be even older. The keen-edged flakes of stone were excavated from an ancient river floodplain in southwest Sulawesi, near the present-day village of Talepu. Some ev
