Mutations are always harmful. They are sometimes not fatal, but they are never an improvement. When genes are damaged or lost, the results are harmful. In speciation, genetic material that's already there emerges, and the new species is "specialized" - where you get the word "species" from. So because it's special it has less genetic material, it's more specialized. Doctors in medicine specialize or isolate themselves to one branch of medicine rather than take on the whole shebang. Same with species. They branch off from the parent kind. It happens suddenly, not over billions of years. It happens when God pulls the trigger so to speak.
Because the moths were there in the beginning. The white moths didn't turn brown because the Industrial Revolution made smoke and soot and made the buildings go from light colored to dark colored. There were already two different kinds of moths flying around. But when the buildings started to get darker, the darker moths fared better than the light ones did.
Well, God didn't program evolution. He just made everything the way it is, and as I say he put the species within the kinds, which we might refer to as "micro-evolution" and some people mistake for evolution -- (evolution meaning new genetic material is formed and simple creatures become more and more complex over ions of time, and plants turn into fish turn into reptiles turn into birds turn into mammals turn into people.)

Yes, a harmful mutation, an extra digit that gets in the way, doesn't work, and needs to be surgically removed. As I said, mutations are almost always harmful, never useful, and result in destruction or loss of DNA material, not new and additional material.
No, God didn't get lazy. If God was lazy he would not have created animals with a reservoir of many spare varieties packed within their genes. That's why those Hobbits were so small on that island, and the miniature elephants. God pulled the trigger, thought the little people would do well on this little island.

Assuming a mutation is beneficial (and you would agree that at least most mutations are not beneficial, yes? Otherwise people would be standing in front of x-ray machines all the time to get more mutations)
Why? Because the theory of evolution claims that brand new DNA and brand new genes are created by accident all by themselves.
But your examples of mutations are talking here about mutations of already existing genes.
We know from our own two eyes, from everything we know and observe in nature that's occurring now or ever has occurred, that this just is not the way it happens. All creatures are what they are, complete and functioning, except for creatures such as butterflys, which if caught in the two weeks of metamorphos in the pupa would appear incomplete or "messed up."
Evolution is a religion,
a belief based on theory that does not even agree with the known facts,

If the shortage of food drove the neck to change, would not the number of neck bones and joints be changeable also by such evolutionary processes? Of course the problem with this design would be a loss of flexibility, and would severely increase breakability if the giraffe received a blow to the head or neck.
Giraffe males fight for dominance over females by clubbing opponents with their massive heads and necks.This intrasexual combat is called “necking” through which larger-necked males gain the greatest access to estrous females and thus, have a greater contribution to the genetic makeup of the next generation.
The sparse fossil record ... gives some insight into the relative size of fossil giraffids (Samotherium) which show a leg length 83% that of the modern giraffe.The fossil records fail to show any parallel increase in neck length in relation to other body parts.
The bull determines a female's time of estrus by taking a sample of urine on his tongue which signals if she is ready to mate (Stevens, 1993). Also, females allow themselves to be urine tested more frequently by larger males. Therefore, males with the largest neck size will mate most often.

Makes sense, eh? I'm gonna continue on in my new style of asking "why?" questions here:

If giraffes were simply meant to be tall so that they could be "lookouts," as you put it, then why didn't their legs and torsos grow proportionally to further extend their height? Why did only their necks grow over millions and millions of years, according to the fossil record?

The reason for the discussion on the giraffe was Astronomer's invitation to discuss irreducible complexity. Do all the parts of the giraffe "need each other" in order to survive? In other words, there's more than just large necks here to consider. There's the special lungs, birthing process, special blood cells, arteries, special heart for a creature like the giraffe to be able to live, and if any of these things were to change the creature could not survive.

I don't believe in evolution AT ALL. I guess you know that. So I'm wondering why you speculate with me how or why the neck evolved, when I don't believe it did. Rather, God made the giraffe the way He did for His own reasons of which we can only speculate. But He did an awesome job in doing so.

I'm thinking this subject may be too difficult to communicate with anyone about. I truly believe God created the world and everything in it in six days just like Scripture said. I mean, I believe this. I feel like I can convince others of this also because to me it's so plain and obvious. So that's why I'm on this forum, to share this understanding and knowledge that I have.

People do have opinions and it's okay to have them, yes? I think I could convince people Creationism is true if I were allowed to proceed in a discussion to the end, and not get sidetracked. If I were to engage in a discussion with someone who was willing to take it to the end, I believe I could convince them that Creationism is true.

I know you are an atheist and you hate creationism and you hate all my opinions,
You need somebody to grab you by your big ears, drag you out to the woodshed and give you a good lickin' and make you stand in the corner.
