I believe it was studied in aiptasia because it is an easy organism to work with. I worked in a lab at a graduate school this summer where a masters student was working with the professor to study autism using yeast cells.. Obviously yeast cannot be autistic. Researchers are using drosophila (a type of fly) as a model for cancer research. I don't think aiptasia has much to do with it. And yes, there is a lot more to be worked out. I was just throwing out some of my understanding of the situation.
