“The mutation caused them to turn on their dna”
or the DNA switched on and off and appears to man’s understanding as a mutation, but in reality is the grand design of our great God and Savior Jesus Christ.
I’m guessing that the oil eating bacteria were/are constantly reproducing (or whatever bacteria do!) and many of them have the plastic eating DNA in them. But - before plastic came around, they just died.
Like the “adaptation” of the white moths to the dark moths in England - the pollution on the light-colored trees and the moths “adapted” dark colors.
And later, once the pollution was gone and the trees were their natural lighter color again, the moths “adapted” and “became” light colored.
It is the same type of moth - it’s just that the white ones got eaten quickly, and the dark ones survived to reproduce more. And now, the light ones survive and the dark ones get eaten. The only thing that changed was the NUMBER of light vs. dark moths.
