Good questions.
Quote: 1. How do you identify where error correction has occurred if it was successful, compared to no error requiring correction?
This is largely a matter of definition. You might argue
I strongly disagree. it's a matter of determining how something might be measured, not arguing over definitions and carefully defining your assumptions to make your model "work". The reality is that you can make any assumption you want but until you specify how to measure the event, the assumption cannot be tested. Assumptions are important - you can't invoke them like 'God' as some non-testable airy-fairy "thing out there" - it's got to be based on previous evidence and testable. In essence, for every assumption you invoke, you've got an underlying hypothesis that has to be tested in order to rigorously defend your analysis.
That's why statisticians bothered generating models which are free of assumptions of any particular distribution (such as normal), instead of doing it the easy way.
The analysis here uses the assumption that point mutations can occur at essentially any location on a gene.
Again, where is the technology to test what is actually happening? Error correction is really, really ephemeral. If you don't see the "expected" number of mutations (based on a complete genomic analysis??? this is getting expensive fast!), then your options are:
1. your expectation (ie assumptions) were wrong
2. error correction has occurred
3. some other mechanism is in play
4. some combination of the above
5. something you haven't thought of yet.
And there is NO WAY to shed light on which it is, until you find a way to MEASURE THE PHENOMENON.
Your response to my #2 above also invokes more assumptions than I'm at all comfortable with. Again, assumptions have to be based on prior evidence of SOME sort. Remember, an assumption is a hypothesis.
One of the major problems with your model as explained so far is that you dump a huge number of assumptions into a black box and don't appear have a mechanism to determine whether your observed outcomes are due to actually rejecting your hypothesis, to one (or many) of those assumptions being incorrect, or to your model not manipulating the data in a meaningful way.
As Forest pointed out, 'fitness' is heavily reliant on the immediate environment over time for an individual. One of the problems as I see it is a confusion over 'logical depth' - you are trying to look at a gross outcome (survival or reproduction - which one is not even clear) in order to test mechanisms which are occurring at a much, much smaller scale. This is akin to trying to examine the atomic structure of bricks by visiting a construction site.
