Hello, AV1611VET. I have been following you for many years, and I hope I can finally engage in conversation with you.
Now, it might help if you think of how DNA is replicated. DNA is an acid made up of little building blocks that act like the code for how to build a living thing. You need a whole set for every cell in your body (and there are quite a few cells-- many trillions in fact!)
I'm sure you know that cells split-- Creationists and Evolutionists can agree on that
Every time our cells split, they need to make a new set of DNA. The process itself is tricky, but the code is broken up into chunks and reformed in each cell. This process is not perfect.
Going from STOP -> STOOP is a mistake. It is not a willful addition of information. Somewhere in that tangling and untangling, breaking apart and reforming that goes on when DNA is replicated, a mistake was made and a chunk was added. Sometimes, people even have whole extra chromosomes as well. These are all errors in the duplication process.
This is almost always bad, as we can see from people born with extra chromosomes. Often, these extra chromosomes make it impossible for a fetus to develop as the genetic code makes no sense. This happens with cells as well; if a cell has a changed set of DNA, it may not be able to survive, or it may even develop into cancer.
Yes, they are almost always bad and our system has a way of deleting mistakes.
Very rarely, the mistake might be beneficial. Now, we don't need to get into the nitty-gritty. We don't have to argue about whether or not a duck can grow extra arms or a cat can sprout wings. Understanding the basics would help you understand why these things do not happen.
Yes you do need to get into the nitty gritty because evolutionists use examples like immunity as examples of beneficial mutations which are never going to change a deer into a whale. Your best example in drosophila where after 35 years, comparable to 12,000 human years, did not fix an allele in the population for accelerated development. How less likely is it going to occur in the wild.

What's more the drosophila that did display accelerated development lived shorter lives, weighed less and were less resistant to starvation.
Your classic sweeps are rare, if they happen at all.
Subtle shifts, not major sweeps, drove human evolution
So let us just focus on one teeny-tiny bit of the whole puzzle: mistakes made when replicating DNA. We can agree that they happen, no? Again, let us not worry about the larger implications. I would simply like to explain, as fully as you would like, that bits of DNA can be lost, changed, or added.
No, duplications, are just that..duplications of same for a start. The difference between a deer and a whale amounts to more than gene duplications as is the difference between a chimp and human. Secondly the evidence is that duplications are disadvantageous, similar to the majority of mutations eg trisotomy21. There is no evidence to suggest that say the opposite occurs such as duplications that cause lets say exceptional ability or some advantage.
Does gene duplication provide the engine for evolution?
Further to that, and most importantly your researchers have no idea really what goes on with gene duplications and changes in function. It is all speculative and at times a wish list. Wiki speaks to the list of theories around gene duplication. Many theories in fact demonstrates conclusively that scientists do not know and can only speculate. The point being the latest flavour of the month means little.

Evolution is full of hopeful claims and theories that really never amount to anything.
Do you have any questions?
