Another one from New Scientist. Although it should come as little surprise, scientists investigating a cave in Australia, where dozens of fossils have been found, have concluded the the continents megafauna were wiped out by man. An extract:
Australian megafauna died out roughly 40,000 years ago, and Prideaux says the discovery that they survived in an arid environment undermines one of two popular theories for what killed them off - namely, that ice-age aridity was responsible. That leaves the second theory, which suggests that the giant kangaroos and wombats were wiped out by the actions of humans, either through habitat destruction or hunting, says Prideaux.
That conclusion is supported by other discoveries by teams led by Prideaux in the Naracoorte caves in south-eastern Australia. Fossils here showed that many species of megafauna survived the recent ice ages - except the last one, which occurred after humans had arrived
The more we learn about prehistoric man and his impact on the environment, the more we realise that the rest of nature had no real defence against our species greatest strengths: intelligence and communication. Mammoths, dodos and ginormous wombats. They had no chance really.Go Top
