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.
I wonder how many people die each year due to their blind spot? I'm guessing probably none.
