I agree with it in principle, if not to the exact details. I don't need to have 100% of the details worked out any more than evos do. The evidence is that there is a known history of animals coming to Australia. In fact, much of the article agrees with evos on how animals migrated to other parts of the world. The difference being the time frame.
Too many times I have been drawn into arguements over what is or isn't a prediction. You and I will not agree on anything here. As for evolution's vaunted "predictive power", I have yet to see an evolutionary prediction that preceded what was predicted. It is more like the WTS claiming to have predicted that Jesus came in 1914.
