Other recent discoveries include a glowing protein in jelly fish that allows surgeons to illuminate cancerous tissue while they operate to remove it.; and a starfish  called the brittlestar, coated with tiny lenses that act as a collective "eye,"  which engineers are using as a model for creating sensors and guidance systems. 

Randy Kochevar, a marine biologist, described the brittlestar as incredible:

"We're looking at these things that are not known to be visual animals yet we're finding these fiascinating optical properties that are built into their bodies."

In his book Superforce:The Search for a Grand Unified Theory Of Nature, Australian Astrophysicist Paul Davies asks us to consider these insightful questions: 

If nature is so "clever"  as to exploit mechanisms that amaze us with their ingenuity, is that not persuasive evidence for the existence of  intelligent design behind the universe?  If the world's finest minds can unravel only with difficulty the deeper workings of nature , how could it be supposed  that those workings are merely a mindless accident, a product of blind chance?

The giraffe

Being a rather tall person myself (6'6") there are not many beings I look up to - except at the zoo, where I was surprised to find myself looking up - way up!  - to a bunch of giraffes!  Despite their height - up to 18 feet - they could run very gracefully (unlike me!) . I wanted to find out more about this unusual animal.


One thing I learned is 
that the giraffe needs a
 powerful heart to pump blood up its long neck to the brain.

If we want to believe in evolution, let's imagine that the very first giraffe manages to evolve the two-foot-long heart it needs to get blood up a neck so long. Its heart is now so powerful that as the giraffe bends its head down, the increased blood pressure is more than enough to burst the blood vessels in its brain.

So this first giraffe must be intelligent enough to realize that an improvement is needed and then set out to somehow grow an incredibly complex organic structure to fix the problem.
  
And it must do so within a matter of days - before it dies of thirst or brain damage - or else this new species will shortly be extinct. (Of course how would it know an improvement was needed unless it had first had a brain hemorrage?  And then it wouldn't know anything. It would be dead.)

Through evolution, which is imagined to consist of mindless, totally random accidental chance processes occurring over long periods of time, the creature manages to quickly devise a protective mechanism to prevent it from blowing its brains out when it gets its first drink of water.

Dr. Jobe Martin describes this amazingly detailed solution :

As the bull bends its head down ...., valves in the arteries in the neck begin to close. Blood beyond the last valve continues moving toward the brain. But instead of passing at high speed and pressing into the brain and damaging or destroying it, that last pump is shunted under the brain into a group of vessels similar to a sponge.... The brain is preserved as the powerful surge of oxygenated blood gently expands this "sponge"  beneath it.

However, from this mechanism another problem arises. A lion creeps up and prepares to kill the spotted prey. The giraffe quickly raises its head and, without something to compensate for the reduced blood flow passes out . It got up too fast , generating low blood pressure and diminished oxygen content in the brain. The lion eats a hearty meal, and the giraffe, were it alive, would realize that it had better evolve some mechanism to re-oxygenate its oxygen-deprived brain!  We all know that animals that have been eaten by a lion don't evolve anything, even though evolutionists would have us believe that creatures evolve the necessary-for-life improvements as they  are needed for survival.

But the giraffe survives! ... as he begins to raise his head, the arterial valves open . The sponge squeezes
its oxygenated blood into the brain ; the veins going down the neck contain some valves, which close to help level out the blood pressure, and the giraffe can quickly be erect and running without passing out and becoming lion lunch.


And it does all of this automatically. The giraffe is another amazing creature that defies the theory of evolution. Do you really think there's any way the giraffe could have gradually evolved and developed its special features randomly over time, as evolution demands?

Remember, if there is even one creature that could not have evolved, then there must be a Creator.
