The world’s oldest boomerang is older than previously thought, casting new light on the ingenuity of humans living at the time.

The tool, which was found in a cave in Poland in 1985, is now thought to be 40,000 years old.

Archaeologists say it was fashioned from a mammoth’s tusk with an astonishing level of skill.

Researchers worked out from its shape that it would have flown when thrown, but would not have come back to the thrower.

It was probably used in hunting, though it might have had cultural or artistic value, perhaps being used in some kind of ritual.
