“Seeing” Is Believing!
Charles Darwin, in The Origin of Species, admitted he struggled with this evidence. He said: “To suppose that the eye with all its inimitable contrivances for adjusting the focus to different distances, for admitting different amounts of light, and for the correction of spherical and chromatic aberration, could have been formed by natural selection, seems, I freely confess, absurd in the highest sense,” (1859, p. 170).
In this specific context, it can be said: Seeing Is Believing! Can the reality of human vision be attributed to a random process or natural selection even with mutations?
I delivered five sermons on evidences a few years ago. The series was geared toward young people and parents. Several mentioned how powerful just this single piece of evidence is. From the source indicated below, I read this:
The Human Eye
The human eye is enormously complicated – a perfect and interrelated system of about 40 individual subsystems, including the retina, pupil, iris, cornea, lens and optic nerve.
For instance, the retina has approximately 137 million special cells that respond to light and send messages to the brain. About 130 million of these cells look like rods and handle the black and white vision.
The other seven million are cone shaped and allow us to see in color. The retina cells receive light impressions, which are translated to electric pulses and sent to the brain via the optic nerve.
A special section of the brain called the visual cortex interprets the pulses to color, contrast, depth, etc., which allows us to see “pictures” of our world. Incredibly, the eye, optic nerve and visual cortex are totally separate and distinct subsystems. Yet, together, they capture, deliver and interpret up to 1.5 million pulse messages a milli-second! It would take dozens of … supercomputers programmed perfectly and operating together flawlessly to even get close to performing this task.
Logically, it would be impossible for random processes, operating through gradual mechanisms of natural selection and genetic mutation, to create 40 separate subsystems when they provide no advantage to the whole until the very last state of development and interrelation.
How did the lens, retina, optic nerve, and all the other parts in vertebrates that play a role in seeing suddenly come about? Because natural selection cannot choose separately between the visual nerve and the retina.
The emergence of the lens has no meaning in the absence of a retina. The simultaneous development of all the structures for sight is unavoidable. Since parts that develop separately cannot be used, they will both be meaningless, and also perhaps disappear with time. At the same time, their development all together requires the coming together of unimaginably small probabilities.
Think of how powerful this evidence is … that we carry in our heads!
