"A shark that can change color? Yes! Based on a new study of nanostructures in the skin of blue sharks (a species of requiem shark that inhabits open, deep waters), scientists now believe that these sharks can actually change color as they dive, better matching the water around them.
"Blue is one of the rarest colors in the animal world, and blue sharks get their striking blue color from nanostructures working together in their dermal denticles (a special type of skin design that looks like
teeth, which is why sharks feel like sandpaper). Guanine crystals reflect blue light, while melanosomes absorb other colors. Environmental pressures change the intensity of the effects of both of these structures. When sharks swim deeper, the nanostructures compress, making the sharks darker to camouflage in the deep. When sharks swim toward the surface, the nanostructures spread out, making the sharks lighter. When the denticles drift closer, they look bluer. When they drift apart, they can appear more green or more gold. These discoveries are inspiring thoughts on how to make color dyes that are nontoxic."
Now, sharks are believed by evolutionists to be some of the oldest organisms on the planet (predating trees and even the North Star in their worldview), first arriving in the oceans 400 million years ago. And, over the hundreds of millions of years, they’ve barely changed! They forgot to evolve! Yes, in the evolutionary worldview, in nearly half a billion years, earth saw massive changes to the temperature, topography, chemical makeup, and life forms in the oceans—but sharks forgot to evolve. What nonsense.
This new study highlights, once again, the complexity of God’s creation. Sharks didn’t evolve complex skin that is perfectly suited to their environment by chance, random processes 400 million years ago. Sharks, in all their complexity, were created by God on day five of creation week, along with the other swimming creatures." AIG
