Repeated effectiveness in surviving.
I believe sirch was more focusing on the “introduces” not “perpetuates” part of the question.
My evidence for this is a lack of the words “perpetuate” “communicate” or “repeat” in the quote.
DNA sequences are echos. Effective “echos” reach our ears (survive, multiply, etc.) Now, where did the introduced noise come from?
How does "surviving" produce information to direct a cell in becoming part of what it will end up being?
