'Hobbit' island's deeper history
Long before a 'hobbit' species of human lived on Indonesia's Flores island, other human-like creatures colonised the area. That much was clear.
But scientists have now been able to date their presence to at least one million years ago - some 120,000 years earlier than previously recognised.
The team reports the discovery of these humans' tools in the journal Nature.
The group says the finds bring a new dimension to our understanding of the history of Flores.
Lead author Adam Brumm told BBC News that the location and circumstances of the tools' preservation meant human occupation of the island could extend deep into the past.
