The “Eye’s” have it
One of the challenges to the belief in evolution is the eye and the systems involved in eyesight. The principle is referred to as Irreducible Complexity and using vision as an example, eyesight involves the simultaneous development of the eye, optic nerve and brain to make sight possible. However, on Cosmos, the Journey of the Imagination, this is not a problem. Beginning of course with tons of time, we’re to imagine an environment where a very simple organism has a mutation which enables it to suddenly sense light. Now assuming one mutation could allow the detection of light, other simultaneous mutations would be necessary to allow the organism to “see / interpret” that light such as a connection / conduit to its brain. The probability of 3 simultaneous positive mutations occurring is only on in a billion trillion (only is of course a tongue in cheek expression). The show even provides a simulated split screen view to show how the light might have appeared to the organism.
From this early start we’re to accept that additional mutations eventually resulted in the development of the human eye (one organ, but composed of many systems: cornea, iris, muscles, retina stem, rod and cone cells, fluid, etc.,), the optic nerve to carry the signal to the brain where the image can be read as sight. Other examples of Irreducible Complexity can be observed in a single human cell or in an animal such as the woodpecker or giraffe.
From a biblical standpoint, there is one miracle that Jesus performed that demonstrated beyond the shadow of a doubt that He is the Promised Messiah. In the Old Testament it was foretold that the Messiah would heal the blind. It was not until Jesus earthly ministry that a person born blind from birth was given their sight (See John chapter 9 for more details). Even today with all the technical advances restoration of eyesight is just becoming possible by small circuits designed by intelligent designers. Of all the aspects of creation the ability to see is one of the great demonstrations of our Creator. Jesus said, “I am the light of the world. If you follow me, you won’t have to walk in darkness, because you will have the light that leads to life.” (John 8:12)
