    • COMING PALMTALK CHANGES - PLEASE READ   02/14/2017

      In the coming week (probably beginning this weekend), several major changes will be occurring with PalmTalk. The result will be short periods of complete closure, or of limited viewing (that is, no posting - but viewing still possible). These changes are major and unexpected complications are always a possibility. So, please be patient and bear with us. For those interested, the first phase will be a migration of the entire site to a new more powerful server. After this is completed, a major upgrade to the newest version of the forum software will then be attempted. It is hoped that these improvements, along with some new configurations of various parameters made possible with the new server capabilities, will result in an elimination of some error messages and glitches which have been plaguing various tasks and viewing recently. As with any upgrade there will probably be some new and/or changed features, or ways of viewing and/or using the forum. I anticipate these will be minor, and as always if there is anything confusing or needing explanation, we will set up a topic to discuss them.

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.
