Uncommon Descent Serving The Intelligent Design Community

Liu Bolin is almost as good as nature


Here. Or here.

And he did it all by natural selection acting on the random mutation of mindless neurons in his brain. Just like those insects.

But not like anyone else.

Just happens. Believe or else.

Caribbean Reef Squid: A Conundrum for Neo-Darwinian Evolution? - by Melissa Cain Travis - February 20, 2013 Excerpt: A spectacular example of a creature that seems to utterly defy naturalistic explanation is the Caribbean reef squid, known by the scientific name, Loliginidae sepioteuthis. These highly intelligent cephalopods (the broader animal category that includes squid, octopuses, and cuttlefish) utilize a stunningly sophisticated mode of communication that is based upon lightening-fast changes in the colors, patterns, and textures they exhibit in their skin. The squid have dynamic structures in their skin called chromatophores that are used to cause these changes. The squid also has special structures that reflect or absorb incoming sunlight to help form all the various skin colors and patterns. The iridescent areas are called iridophores. In less than 30 milliseconds (yes, milliseconds!!), and in response to a visual cue, the squid can purposefully change its color and pattern to communicate with another squid, court another squid, stun their prey, or to try and ward off or confuse a potential predator. Many of the color/pattern displays include certain arm postures, as well. The squid can manipulate its color/pattern display in order to make it appear to move across their body. http://sciencereasonfaith.com/caribbean-reef-squid-a-conundrum-for-neo-darwinian-evolution/ bornagain77

And of course Darwinists have no clue how this amazing ability came about:
Mechanism behind squids' and octopuses' ability to change color revealed: Biomemetics This Time: Tunable Photonic Materials - July 26, 2013 "Initially, before the proteins are consolidated, the refractive index -- you can think of it as the density -- inside the lamellae and outside, which is really the outside water environment, is the same. There's no optical difference so there's no reflection. But when the proteins consolidate, this increases the refractive index so the contrast between the inside and outside suddenly increases, causing the stack of lamellae to become reflective, while at the same time they dehydrate and shrink, which causes color changes. The animal can control the extent to which this happens -- it can pick the color -- and it's also reversible. The precision of this tuning by regulating the nanoscale dimensions of the lamellae is amazing."
And here is a more technical description, from the journal paper:
"Squids have used their tunable iridescence for camouflage and communication for millions of years; materials scientists have more recently looked to them for inspiration to develop new “biologically inspired” adaptive optics. Iridocyte cells produce iridescence through constructive interference of light with intracellular Bragg reflectors. The cell’s dynamic control over the apparent lattice constant and dielectric contrast of these multilayer stacks yields the corresponding optical control of brightness and color across the visible spectrum. Here, we resolve remaining uncertainties in iridocyte cell structure and determine how this unusual morphology enables the cell’s tunable reflectance. We show that the plasma membrane periodically invaginates deep into the iridocyte to form a potential Bragg reflector consisting of an array of narrow, parallel channels that segregate the resulting high refractive index, cytoplasmic protein-containing lamellae from the low-index channels that are continuous with the extracellular space. In response to control by a neurotransmitter, the iridocytes reversibly imbibe or expel water commensurate with changes in reflection intensity and wavelength. These results allow us to propose a comprehensive mechanism of adaptive iridescence in these cells from stimulation to color production. Applications of these findings may contribute to the development of unique classes of tunable photonic materials." What we see here is a beautiful design consisting of a sequence of highly complex, intricate and finely-tuned mechanisms, molecules and structures allowing these organisms to precisely control their image. There is no scientific evidence that such optical technology arose from random mutations as evolutionists believe. Evolutionists like to call upon natural selection as a sort of natural designer, but that does not help for such intricate designs as these. http://darwins-god.blogspot.com/2013/07/biomemetics-this-time-tunable-photonic.html

Caught by cameras fitted with yellow-colored filters, fish such as the flathead (Cociella hutchinsi), found in the tropical Pacific Ocean, become show stoppers.
