Color Change in Animals

So far, the only animal I've encountered that can change color is Hyla chrysoscelis, the Gray Tree Frog. Color change among animals is highly complex, and our understanding of it is unfortunately skewed by evolutionary theory. However, here are the basics: http://magma.nationalgeographic.com/ngexplorer/0210/articles/mainarticle.html

"Chromatophores change because the cells get a message from the brain." The question is, then, how does an animal know to change color? Sensory perception makes sense (if the temperature changes, etc.), and mood (the animal is frightened, it might change to ward off predators), as does instinct (the animal's brain might act out of the instinctual need for a mate, signalling to the skin's chromatophores to follow the "program" that God wrote into them). But what about changing color to blend in? According to this site, http://www.colormatters.com/color-matters-for-kids/how-animals-see-color, frogs might be able to see some colors at night, but basically they see color just as poorly as many other animals.

Evolutionists will tell you that animals adapt to situations and pass on those new traits/abilities to future generations (e.g. legs, higher intelligence, lungs, wings, camouflage, etc). I disagree with this. I believe that God gave certain traits and abilities to animals at the beginning, when He created them, and that they act according to what He programmed into them (like writing code for a computer). That's not to say that individuals can't adapt to an ever-changing world, but whole species, genera, and families? That's stretching it. Scientists must take into consideration the reality that animals react to information they receive from the countless stimuli in their environment. They don't do anything consciously, but instinctively. They aren't aware of their existence, of their appearance, of what's happening inside their bodies. They see (usually poorly), feel, smell, taste, and (sometimes) hear, and they react based on the pattern in their brains. If an animal isn't self-aware, it can't "evolve" through generations. Why would an organism want to leave the water and sprout legs? How could it communicate the need for camouflage? Why would our "primal ancestors" achieve higher intelligence and how would they know to do so?

Humans experience the same kind of chemical/electrical signals and stimuli and processes in their brains as animals, but with the added feature that they are self-aware. They don't have to act out of pure instinct. They can try to control their bodily functions and psychological reactions, just as they can assess and analyze their physical and mental state. And this isn't something that evolved; it's God-given.

In closing, here are 4 photos of our tree frog(s) with varying color and pattern:
