the BBC today has an article showing that many scientists are debunking the idea that the mass extinction of megafauna in the pleistocene - like mammoths and sabretooths and cave hyaenas and giant sloths and the like - was not the work of meat-happy hominids, but rather of climactic change.
speaking of the practicalities of the matter, dr stephen wroe of the university of sydney observes,
There is not a single stone-spearpoint in Australia until, at the very earliest, about 15,000 years ago - long after anyone thinks the megafauna went extinct.good point, steve.You try taking out a two-to-three-tonne wombat with a pointy stick.
the picture is of aforementioned wombat, namely diprotodon optatum.
