Actually, it's both. If you don't understand that mutations can and do add information to the genome, then you do not understand evolution.
I understand the proposed evolutionary method, dont worry. I do understand evolution and you must get tired of people saying this but this is truly what I believe there is a big difference between Micro-evolution and Macro-evolution. Evidence that mutations change a species over time is not in contention. The theory that species change into another kind of species, thus explaining the vast complexity of life is what is in contention.
The most commonly used debating tool that I have come against is people arguing microevolution and then assuming victory. Sometimes they thought they were arguing for macroevolution but actually they hadnt progressed from within species variation. This is thankfully not going to happen here, I trust.
Well, the bacterial flagellum was the case held up by creationists as the kind of "posterboy" for irreducible complexity, and is often held on it's own as "proof" of irreducible complexity.
So, aside from the flagellum or the eye - both of which have been proven to not be irreducibly complex - can you provide any more examples of supposedly irreducibly complex biological systems?
Well, I have just had a quick read of the proposed proof the blood clotting cascade is reducibly complex by the fact that one of the proteins is missing in whale. Is that it? Surely Im missing something that doesnt actually address the issue. Can you attached the best counter argument against the blood clotting cascade being irreducibly complex this is the one that I understand best (although it has now been 8 years since I studied in detail!)
The supposed proof that the flagella is reducibly complex by the fact that there is a similar very complex TTSS. But then where I have read it states that 40 proteins missing! 40 proteins! That is an awful lot!
No, it doesn't. "Proven" means simply "demonstrated to be true". It is as proven that the sedimentary layers of the earth's crust were formed over long periods of time as it is proven that gravity is the force that keeps us all from floating into space.
This is not true at all. You need to choose a better example. Sedimentary rock layers forming over millions of years not observable.
Gravity is force that keeps us from floating into space observable and repeatable.
Try again.
But that's not what it's based on. Again, look into geochronology. There is a multitude of evidence that all points to the same clear conclusion. You have yet to present anything that refutes that evidence other than your own personal opinion that "what happened in the past cannot be known". Like it or not, we can still test it. It has been tested, and discovered to be true.
The whole issue of radio-isotope dating is a whole other thread. I have looked at the geochronology issue. In order for these to be reliable, we need to know certain things that we can not know for certain there will always be assumptions with error bars, some may be significantly large.
I did, and found it is all loaded with the exact same logical fallacies as above. You ignore the evidence and just accuse us of "assuming" all the time. It's just a prolonged argument from ignorance.
I am not ignorant. I merely disagree with you, there is a difference. I know the majority of your arguments, some better than others.
This is a complete contradiction of your previous statement: "To assume that what happens now is definitely what happened in the past is an error."
Just because layers of rock can be formed by a volcano does not mean they all were, nor does it do anything to refute the mountains of evidence that they were formed over long periods of time.
This is not a complete contradiction what I am suggesting is that we have observed sedimentary rock layers being formed and it did not take a long time. Therefore, it is wrong to assume that it MUST take a long time. The issue of whether the sedimentary rock layers took millions of years essentially goes on to the reliability of the dating techniques essentially. And I suspect that is where the discussion will lead us sadly.
And how does the fact that they are "retrospective" do any harm to their conclusions? Science is about finding out the truth through carefully observing the facts in front of us - and those facts have all unanimously lead to the same conclusion. Your argument requires us to ignore this evidence purely on the basis that "it's not observed". It's a tired argument from ignorance.
You do like the word ignorance dont you?
Anyway, again, you still are not getting my overriding point that you must make assumptions to extrapolate data back in time. It is inevitable. That is what we must do. We just have to be aware that we must be more humble about our conclusions. If you start with the wrong assumptions and then apply them to the data, you will ALWAYS come to the same conclusion. You can then run it millions of times and think that your conclusion is correct due to sheer weight of numbers. That is not how science works. That is how science is humbled by later generations.
