This is simply not true Interbane. You refuse to recognize that decades long experiments with plants and crops throws up the law of recurring variation. The same mutations keep recurring.
As Jones points out in his talk in relation to the Cichlid fish family,what is observed are variations of recurring patterns based on permutations of a small number of primary characters. The same is true of teeth and even their different behaviours.
There are many species of cichlid but nothing changing from a cichlid to another kind of fish.
It's increasingly evident that variation can occur rapidly and even speciation. For this reason it is even more inexplicable that bacteria and fruitflies over huge numbers of generations do not change fundamentally or show indications of transformation into anything fundamentally different.
You now postulate acquired characteristics. Fair enough but even these are not fundamental changes to the essential nature of the animal.
You have to demonstrate that these minor changes amount to major changes over time. Bacteria, fruitfly,plant and crop experiments say no.
As Berlinksi points out in relation to finch beak shapes and sizes, there is a correlation with seasons and weather events ( e.g.droughts) and they alter back and forth. Nothing major and they remain finches.

Can you provide an example of macro-mutations doing anything of the kind? How would this work for the land mammal to whale transformations?

Regarding macro-mutations, do you have evidence of these? Why do you assume such a thing isn't merely the accumulation of many micro-mutations? Or a single micro-mutation with a large phenotypic effect?
You referred to environment related phenotypic change and now mutation generated large phenotypic change. There's a reason that major phenotypic change is not possible. Developing new body plans would involve changes at the early stages of development.
Here's the problem with this. It's a brief talk by Paul Nelson and I suppose the creationist source will be enough to put some off.

Phylogony? Morphologically based genealogical trees vary significantly from genome based ones. What molecular evidence?
Historical vestiges? Evolutionist myth of non functional vestigial organs and rapidly diminishing "junk Dna".
A failed prediction of the theory.

You certainly can't Interbane. Show me where biologists have described this evolution biochemically. They line up dubious and even discredited fossils as if these were proof of whale evolution.
You could a better job lining up dog fossils to "prove" the direct linear descent of the poodle from the great dane. It's a joke.

Wouldn't entire biological systems,respiratory,visual, audio, circulatory and on and on, have to change completely and in an integrated and co-ordinated way?
And mutational errors in transcription will perform this miracle?
Are you unaware this is an argument from incredulity? Mutational errors alone do not accomplish this. The culling of the environment selects between the mutations.
But mutations do occur in mutagenic clusters - mutation showers. There are buffers to mutations where areas of the genomic code more likely to result in a stillbirth or nonfunctioning organism mutate less than other areas.
You are not even close to getting to grips with the problem of integrated complexity. Are you suggesting entire biological systems changes can be accomplished instantly by a single mutation or a series of mutations? Back to the early developmental problem again.
So obviously I'm not going to convince you, and you are not going to persuade me to change my mind.
If you really want to investigate the very real problems with the whole macro story, Michael Denton's recent book "Evolution still a theory in Crisis" does a far better and more detailed job on this than I can.
