The real problem is that genetic mistakes accumulate.
That's not a problem. That's a survival mechanism.
If DNA wouldn't mutate, and if these mutations wouldn't accumulate, then species wouldn't be able to equip themselves against new threats in an ever changing environment and it would only lead to extinction.
Calling them "mistakes" isn't going to change that.
And once again, the problem with incest = lack of genetic diversity.
In the case of incest, there is not as good chance to fix genetic problems, because the material is too similar, has the same mistakes
"mistakes", aka mutations, have nothing to do with the fact of lack of genetic diversity.
How many times must it be repeated?
Sounds like you really have no clue what genetic diversity actually is and sounds even more like you don't want to know either.
If DNA has no mistakes yet, then there is no such problem.
Once again: mutation has nothing to do with diversity.
A population of a single breeding pair, by definition, has virtually no genetic diversity and is thereby doomed to extinction. No sexually reproducing species is able to overcome that.
In general, the viability threshold of a population is around 200 individuals (who, off course, can't be closely related to eachother). Anything below that is pretty much doomed to extinction due to lack of genetic diversity.
Your whole case about "corrupt DNA" has nothing to do with that. Nore is that even a thing. There's no such thing as "corrupt DNA".
You like to claim that mutation is a bad thing. If mutation wouldn't happen, the species would go extinct. Mutation is
crucial for survival in an ever-changing environment.
So, in a way, I think we agree
We most definitely, absolutely, do not. Not even remotely.
For starters you're still showing deeply rooted willful ignorance about what genetic diversity actually is...
And secondly, you keep on rambling about the nonsensical notion of "corrupt DNA" and "perfect genes". Neither makes any sense in context of genetics. They are non-issues. These are "invented problems" by creationists who have no clue what they are talking about and who are talking out of their behinds.
, but the key is not really the diversity
Except that it is.
Genetic diversity is crucial for the viability of any given population / generation.
Incest is a problem, because of the lack of genetic diversity.
, but the amount of genetic information that has errors.
No. This is mumbo-jumbo. It makes no sense and it is an invented problem - not an actual problem.
If the DNA is without errors, it is no problem genetically to have no genetic diversity.
You make zero sense. I don't even know how to respond to this any more. You are really insisting on being incorrect.
DNA copy process has systems that try to prevent mutations (mistakes in the process), because they are normally always harmful.
This is false. The vast majority of mutations are neutral.
A minority is harmful (they are quickly out of the genepool, as organisms with harmful mutations don't usually get to survive and reproduce).
Another minority is beneficial (these spread thoughout the genepool and achieve fixation, as organisms with those mutations have an advantage over their peers in terms of reproductive succes and overal survival).
The goal in the system is not to have mutations.
First of all, there is no "goal" in the "system". The "system" is a chemical process.
Secondly, regardless of "self repair" mechanisms, every newborn comes with a set of mutations. It's generally referred to as the "mutation rate" of a species. In humans, the mutation rate is about 55-ish.
That means that every human newborn has about 55 mutations in its DNA.
Off course, none of this has anything to do with the fact that lack of genetic diversity is what causes the problems in off spring that is the result of incest / inbreeding.
