So full fledged macro evolution is falsifiable ?

Evolutionary change is not a theory, it is an observation. Species can be identified in rock sediments that are no longer alive and that differ markedly from creatures living today.
Genetic evidence helps to map the relationship between species. Farmers breed a range of animals and enthusiasts breed dogs or pigeons (but not often the combination of these).
The flu virus changes and mutates repeatedly and we can observe how one strain prospers and others fade.
We know evolution happens, we can map the genealogy and the common ancestors of every living species and many extinct ones. And since we know it happens and can map its progress through time and we can correlate evolution with environmental changes in the history of the planet, then the idea of belief or non belief does not really arise. It is a brute fact.
What remains is the need for an explanation - it is obviously posssible you idiot since it has obviously happened and obviously continues to happen. Talk to the Dodo about it. Talk to a pigeon fancier about it.
Talk to a health worker dealing with a newly antibiotic resistent strain of an infectious disease about it.
Give us a biblical account of drug resistent disease or a biblical explanation of the consequences of feeding antibiotics to farm animals.

I raised this point in a different thread where it was ignored, but maybe you would like to give it a whirl. Suppose we take the micro-evolution hypothesis and assume it is valid. Then, for each species, there must be a part of their DNA that can change and a part that is immutable, otherwise the DNA cannot "remember" that it should only change "a littl ...[text shortened]... mechanism is this segment of DNA protected from mutations?

Yep. "Full-fledged macro-evolution," i.e. evolution is a perfectly falsifiable theory.
I was listening to another Unbelievable? podcast the other day which featured a debate between ID proponent Michael Behe and ID opponent Keith Fox – both are biochemists. During the discussion Behe talked about the longest running lab experiment to test the effects of Darwinian evolution on E. coli. Professor Richard Lenski has been growing trillions of E. coli over more than a decade and he has produced tens of thousands of generations.
According to Behe, the net effect of natural selection and random mutation on the E. coli has been mostly to break biological systems that were already in place. No new complex systems have been formed by Darwinian evolution in the experiment.
Keith Fox agreed with Behe’s assessment of the experiment, but claimed that it did not prove anything about the limits of Darwinian evolution to produce complex new biological systems (which is a central claim of Darwinists). Behe asked Fox, “If this experiment doesn’t prove anything about Darwinian evolution, then what kind of lab experiment could falsify Darwinian evolution?” Fox’s answer: none.
According to Fox, lab experiments can never replicate the natural selection pressures that E. coli or any other organism face in the natural world. These pressures can not be simulated in a lab. It seems that the mechanisms of random mutation and natural selection must be assumed – they cannot be falsified by experimental biology.
What we have here is an unfalsifiable theory. No matter what experiments are run to test Darwinian evolution, the results can never, according to Fox, disprove its ability to generate new biological systems. Aren’t scientific theories supposed to be falsifiable? Am I missing something?

Originally posted by FetchmyjunkClearly not since evolution is a theory of how species change over time and creation is a somewhat vague term which could refer to the origin of any particular species or the Earth or for that matter the universe.
In your opinion are creation and evolution mutually exclusive?
Originally posted by sonshipNo actually, they don't. Dogs are descended from wolves and clearly did not remain wolves.
The dogs stay dogs. The pigeons remain pigeons.

Originally posted by twhiteheadI don't agree that categories like mammal or bird are something arbitrarily imposed on the animal kingdom by biologists. They reflect features of the animal which are consistent between species within the groupings. So a mammal is a mammal because the females suckle their young, which is why the Echidnas and Platypuses are categorized as mammals despite laying eggs. Further genetic evidence has been used to improve the groupings between species. So, although it is undeniable that the categories have been invented by man they do reflect actual properties of the beings they categorize.
No actually, they don't. Dogs are descended from wolves and clearly did not remain wolves.
Pigeons could be bred to be doves given that size is the main differentiator.

But they are still mammals and birds I hear you cry. Well, yes, if you look for a larger category, you will always find one. But we have to re ...[text shortened]... about the animal itself or whether it evolved or to what extent it evolved. Nothing whatsoever.
Originally posted by KellyJayI see. So if I understand your response correctly, you do think that there is such a segment of DNA - coding for the "base type" - that is immune to mutations. How do you explain that we have, in fact, observed the possibility of mutations occurring anywhere in DNA?
In creation life was started and we go from there, the base type of codes were in place the
second the creature was created. From there it can move the needle a little nothing more.
There doesn't have to be a "memory" to stay true to the types of life, the barriers I
described that hinder massive changes enough would hinder a micro life turning into a
dog over a very long period of time.
Originally posted by DeepThoughtYou will note that I made no such claim.

Pigeons and doves constitute the bird family Columbidae, which includes about 310 species.
Originally posted by sonshipWhat kind of lab experiment could falsify evolution? For instance one could take those E-coli and track their reproduction for a very long time. The theory of evolution in the modern synthesis would predict that: a) mutations occur in their DNA, which is what we observe and that b) over time, the E-coli will adapt to their environment, which is also what we observe, as we find brand new features in those E-coli strands - as opposed to the claim in your copy-paste. If nothing happens to the E-coli and they just keep reproducing with the same DNA even when waiting a very long time then that would be good evidence there is something wrong with the theory of evolution.
My own bolding.
