The author has shaky premises. To wit: to wiring which leads to a retinal blind spot “can be described as one of evolution’s “greatest mistakes””.
No. “Mistakes” die. The fit survive.
Evolution naturally selects (pun intended) those adequate, viable and superior shifts in the genome which generate a superior physical structure (i.e., a better eye) because those shifts/mutations (call them what you will) permit more individuals with that altered genome to live, thrive and reproduce.
Just as the Creator envisioned.
None of us are even aware of the 'blind spot' because our remarkable brains fill in the blank.
I have come to believe evolution is a tool of the creator. The real unanswerable question is: Where and when did life begin? I do not believe life originated on earth.
RE: No. “Mistakes” die. The fit survive.
This is how it always sounded to me -— Nature selected and produced each species. The proof is that it did it. How do we know it did it? Because it did it.
Thus we have a question: `Why do some multiply while others remain suitable, dwindle, or die out?’ to which is offered an answer: `Because some are naturally fit to multiply while others remain stable, dwindle, or die out.
SURVIVAL OF THE FITTEST :
Why do certain individuals/species survive? Because they are the fittest. How do we know they are the fittest? Because they survive.
The “mistakes” idea is the Darwinist’s “god of the gaps”. They used to tout “junk DNA” as proof of evolution - until it was discovered that it isn’t “junk”. Now they have just moved on to something else.
BTW, there is no reason why God has to create things with features that we find satisfactory.
When you take a Peripheral Vision test, you focus on a fixed target directly in front of your eyes.
Eye movement capability renders the “blind spot being a mistake” theory irrelevant. The Brain figures it all out.
