The AIG should be talking up this research.  When I visited their 
creation museum in Kentucky they had an exhibit claiming that 
continental drift had occurred within the year of the global flood (the 
current continents moved thousands of miles to their current positions 
within a year during the flood.  Another claim was that there were giant 
living rafts of vegetation (small islands) floating around at the time 
and all the animals, like marsupials, got back to Australia to where it 
had moved during the flood on these giant rafts of vegetation.  I guess 
none of the carnivores were eating meat at this time and all the pairs 
of herbivores made it back to places like Australia and the Americas 
with devine assistance.  The ones that went back to antarctica didn't do 
so well.
