As Alex says, it's simple economics. Nerve impulses work in the same way. If you pick up a hot object the nerves don't repeatedly say "it's hot, it's hot, it's hot", just "your hand is burning up damnit" and "hey, it's all cool now". In other words, they inform of change, instead of repeating information redundantly. |

It's probably more complex than that. The amount of energy required by a few neurons among the 100,000,000,000 in our body is such a little thing that it's not subject to significant selection pressure. Rather, the brain as a whole most likely adopted this kind of logic from the beginning of its evolution. |

So, if they fire once at dawn and once at dusk, and remain quiet during the night and day...how does the body know whether it is day or night? (or is that something completely different involving melatonin, etc) |

You know, I was wondering the same thing Aqua. o_O I have no idea tbh, lol, but I suppose it does have to do with hormones or something. |

I have been nocturnal before. For several months. It got to the point that the very moment I began to see any bit of sunlight dawning my body/mind was like "ok, time to sleep!" ...and the moment it would begin to get dark, I was awake and ready to go. It was strange, but I really enjoyed it. I would probably try to be nocturnal again if I didn't have school during the day. |

198.726% of people will not realize that this percentage is impossible given what we are measuring. If you enjoy eating Monterey Jack cheese, put this in your sig and add 3^4i to the percentage listed.
