448. Your Interesting Topic Of The Day #1
Last night Kristin and I got talking, God knows how, about chameleons and their ability to change their color to match their surroundings. We both were completely ignorant of how it was done, though the why we pretty much assumed was based on needing to blend into their environment as a means of protections against the various big things that lurk with a nice chameleon dinner on their minds. My hypotheses, which was maybe concurred (you'd have to ask her) by Kristin, was that chameleons were privy to sort of using visual stimulation to alter their own physicality, citing certain human instances of visual stimulation that causes real physical reaction, like arousal, disgust or excitement as precedent for this being something that happens in nature. Now, obviously I'm not a scientist* and on further research it turns out I'm completely wrong, not only on how it's done, but why it's done. Chameleons change color as an expression of their condition, be it psychological or biological or whatnot, e.g.** a frightened chameleon might go orange, while an embarrassed chameleon might turn blue. Like how humans turn red when they get embarrassed, except less to do with blood. Nothing to do with blood at all actually, but with these things called chromatophores which are specialized color cells. On the outer layer they have xanthrophores and erythrophores, which contain your yellow and red pigments, while the inner layer has a bit of iridophores, which extract the blue part of light and reflect it, tossing the rest of roy g biv to the curb like a used up whore. The three colors combine, like they do on your television set, to manipulate the way our eye (and any other eye for that matter) sees whatever the chameleons biological instinct dictates. So oddly enough, against popular misconception, chameleons do not change to melt into their surroundings, they change in a combination lock-esque complexity, according to their psychological state of being, their biological state of being, the way light strikes them and on the odd occasion how horny they are, though we'd say that fits in with biological/psychological state of being. This has been your interesting topic of the day. I hope it hasn't bored you.
*i am a scientist, actually.
**which is anglicising Latin, by the way ...it should be g.e., but lets not bog down science with grammar, shall we?
