Who says nothing exciting happens in South Australia?

For hundreds of millions of years life on Earth was prokaryotic. Bacteria thrived and was the only form of life. The environment was relatively stable. Until one day a 5 kilometre wide asteroid hit South Australia creating a crater 90km in diameter with an impact of an estimated 5,200,000 megatonnes of TNT. This asteroid, named the Acraman Asteroid, and the soil and dust ejected as a result had an extreme impact upon atmosphere and the biosphere, changing the global environmental status quo. This change has been argued recently to be the major selective pressure that triggered the Cambrian explosion and all ‘higher’ life – eukaryotes and ultimately us – to evolve.

So as I said in the title, who says nothing exciting happens in South Australia?

And on a completely unrelated topic there was an awesome doco on last night on the Pygmy Elephants of Borneo.  It was filmed exactly where I saw a herd of 30 just on 6 months ago. What an amazing trip that was!
