Australien hat sich aus einem UNESCO-Klimabericht über bedrohte Reiseziele streichen lassen, wie die australische Ausgabe des „Guardian“ am Freitag berichtete. Jüngste Erfahrungen zeigten laut dem australischen Umweltministerium, dass negative Kommentare über den Zustand von Welterbestätten den Tourismus beeinträchtigen. (Quelle: Guardian) Australische Wissenschaftler zeigen sich besorgt über diese Politik. Ihrer Meinung nach ignoriert diese Intervention die ökologische Bedrohung des Great Barrier Riffs.

Australia was one of the earliest regions outside Africa to be colonized by fully modern humans, with archaeological evidence for human presence by 47,000 years ago (47 kya) widely accepted. However, the extent of subsequent human entry before the European colonial age is less clear. The dingo reached Australia about 4 kya, indirectly implying human contact, which some have linked to changes in language and stone tool technology to suggest substantial cultural changes at the same time. Genetic data of two kinds have been proposed to support gene flow from the Indian subcontinent to Australia at this time.Full report can be found here.

We report evidence for the world’s earliest ground-edge axe, 44–49,000 years old. Its antiquity coincides with or immediately follows the arrival of humans on the Australian landmass. Ground/polished axes are not associated with the eastward dispersal of Homo sapiens across Eurasia and the discovery of axes in Australia at the point of colonisation exemplifies a diversification of technological practices that occurred as modern humans dispersed from Africa. Ground-edge axes are now known from two different colonised lands at the time humans arrived and hence we argue that these technological strategies are associated with the adaptation of economies and social practices to new environmental contexts.Full report can be downloaded here.
