The hunters did it.

This afternoon's issue of Science has the Report explaining how it was figured out (spores of fungi that thrive around big animals) and a Perspective giving a fuller explanation. Here's a tidbit from the Perspective. Short version is that Tim Flannery was more or less right:

The Australasian megafaunal extinction story now seems clear. Shortly after their arrival, small bands of hunters had a devastating effect on large animals, whether it was ∼41,000 years ago in Australia or ∼750 years ago in New Zealand (13). Any climate change at those times was modest and highly unlikely to affect the outcome. Fire and massive biome disruption followed human arrival in regions where there had previously been little or no fire, such as wet tropical Queensland and eastern New Zealand....

ABC have a nice story. Keep an eye on the dung, the spores and the charcoal. Really clever paleoecological research.

Jared Diamond wrote about this in his book Guns, Germs, and Steel. Everyone should read this book along with his other 2 - Collapse and The Third Chimpanzee. Collapse scared me.
