1 jan 23000 ano antes da era comum - invention of the boomerangs

Descrição:

Boomerangs are strongly associated with Australia’s Aboriginal people, but were actually used as hunting weapons throughout Europe and Africa. Most boomerangs do not come back when thrown.

The oldest boomerang yet, 23,000 years, was made from a mammoth tusk and discovered in a cave in Poland (Nature, DOI: 10.1038/329436a0).
