Recent findings, made by Griffith University researchers, show that early hominins made a major deep-sea crossing to reach the Indonesian island of Sulawesi much earlier than previously established, based on the discovery of stone tools dating to at least 1.04 million years ago at the Early Pleistocene (or ‘Ice Age’) site of Calio.
Title is a bit misleading (my emphasis)
“This discovery adds to our understanding of the movement of extinct humans across the Wallace Line, a transitional zone beyond which unique and often quite peculiar animal species evolved in isolation,” Professor Brumm said.
“It’s a significant piece of the puzzle, but the Calio site has yet to yield any hominin fossils; so while we now know there were tool-makers on Sulawesi a million years ago, their identity remains a mystery.”
