It's the first predator brain they've found, and it opens up an absolutely fascinating field of evolutionary speculation, summarized in the conclusion:->

I have suggested a mechanism that can do a great deal of its own planning, and the mechanism is in the cell/cell community (of which, of course the genome is a part). Perhaps you can explain why you believe in a “system” but not in a mechanism that can do its own planning.-We need a definition of your cell communities' abilities. I view the cells as run by the genome rather automatically; the genome of course resides in the cells, but is expressed differently in different cells. You make it seem as though the cells can manipulate, of their own volition, the major codes of the genome to make major changes. Who is running the show, the genome as I envision it, or the cells running changes in the genome? All we see at this juncture in research is minor variation created by organisms. The gaps in evolution are so complex cells have to have guidance, which must be in the genome.
