“However, without your being able to describe some mechanism that prevents such small changes from accumulating indefinitely, there is nothing that prevents such changes eventually becoming what you might label “macro-evolution””
I don’t think so. You need to show me that additional information is ADDED to replication information without harm to the life form. Small changes within a species is NOT macro-evolution no matter how many times it happens. Time isn’t the friend you infer it to be.
Additional information is added via the selection process. The individuals that die vs. the ones that survive to reproduce are like a software "if" statement, that in combination with random gene mutations acts to add information to the gene pool. Happens all the time. Drug resistance is a classic example where literally new information is added to the overall gene pool of a pathogen because of the "if" statement of the drug used against it.
I know, you guys call that "micro-evolution" which is not a term that's scientifically recognized. But even a "micro" amount of information added is still information added, so your argument is baseless.
False!
Information does not need to be "added." It only needs to be changed. That is the definition of evolution -- change in the genome through time.
