I wasn't sure if I should post a thread at the David Icke(Lizard conspiracy proponent)forum about the primitive brain. If I read correctly, part of what they believe is not that people are lizards but that they are dominated by their primitive brain in a negative way.
ie the brain our very distant ancestors had as lizards which in human brains is the limbic system(I think) which deals with primitive emotions like love and fear and sex and this is the part of the brain that runs the heart and hormones and other chemicals.
I have read that we evolved from salamander, I dont know if they are lizards or not, I kind of newt.
Anyway I just wondered what the importance of the fish as a symbol for Christianity. I mean the salamander evolved from fish so maybe the fish symbol is referring to the primitive brain. But not in a bad way as the Ick people might think.
