Our preliminary survey of the expressed sequences of planula stage Acropora millepora appears to turn upside down several preconceived ideas about the evolution of animal genomes.........Acropora and human sequences are often surprisingly similar.
For example, the A. millepora EST dataset contains homologs of many bilaterian genes whose specialized functions are associated with highly differentiated nervous systems. These include genes with vertebrate, but no known invertebrate, counterparts .....This complexity is particularly surprising given the morphological simplicity of the coral nervous system...
The complexity of the Acropora genome is paradoxical, given that this organism contains apparently few tissue types and the simplest extant nervous system consisting of a morphologically homogeneous nerve net.

The authors of this study state that their findinds are "paradoxical" due to inconsistency between the organism's "simplest extant organism" and it's genetic complexity. They state this "complexity is particularly surprising given the morphological simplicity of the coral nervous system", and go as far as to claim their findings appear "to turn upside down several preconceived ideas about the evolution of animal genomes."
The authors are evolutionists themselves. My questions to start this off are:
What preconceived ideas do they think appear to have been overturned?
Why do they think their findings are "particularly surprising" and "paradoxical"? What specific facts are they referring to?
What specific genetic complexity are they referring to and how did it get there? For example, they discuss at length comparisions between the human genome and some others, and they draw conclusions about the theoritical common metazoan ancestor.
Note: Please do not request any creationist or ID explanations for the facts presented in the study as I have been warned that will not be allowed. We are discussing what the findings are, how they appear to overturn preconceived ideas of the evolution of animal genomes, and what all that entails. So we will be working within the given assumptions of universal common descent, evo dating techniques, etc,.... for sake of argument.
