Please stop with the "serious convesation" FUD. Structural differences are no barrier to functional equivalence. Transcription factors are proteins that activate or inhibit the transcription rate of other genes, including those of other transcription factors. They do form complex regulation networks that are isomorphic to neural circuitry. Edit: re. ocelloid, I know you didn't literally mean vision. The structure of the retinal body and adjacent organelles suggests that it is more than a focused, single pixel cam that would be used for simple phototropism, which implies that it is tied to a more complex processing apparatus.
