Denial without evidence. Isn't that what you twitted Coulter about? So give us some evidence that natural selection is NOT a two-step process. In the meantime, I'm going to love you arguing with Ernst Mayr:
"The Two Steps of Natural Selection
Step One: The production of Variation. ...
Step Two: Non-random Aspects of Survival and Reproduction"
Ernst Mayr, What Evolution IS, page 119
That is another book you should add to your reading list.
Natural selection does not produce genetic variation, random mutation produces the variation.
"However, natural selection and genetic drift cannot operate unless there is genetic variation — that is, unless some individuals are genetically different from others. If the population of beetles were 100% green, selection and drift would not have any effect because their genetic make-up could not change."

Natural selection transforms existing species into new species. Over the course of generations.
No it does not. Natural selection only populates, or de-populates existing life forms within a population.
And here you are trying to split the 2 parts of natural selection. You are using "natural selection" only for the selection part. However, even here, you are admitting that selection is going to change the population and produce something new.
Quite the opposite. Natural selection will not change the form of the population, it will only increase, or decrease, an existing life form.
You are good at debating tricks. Of course, you just ignore facts when you do. However, what you said is pretty much what I said. The variation is going to introduce novelty. (I can site a bunch of papers documenting where this has been observed, with new traits appearing.) However, not all variation is due to mutations. Recombination and random movement of homologous chromosomes actually provide most of the variation in sexually reproducing organisms. Which shows that there can be a lot of variation, considering that each human has about 20 mutations.
The mechanism of change is mutation, according to UC-Berkeley.....

Which is why natural selection is a 2-step process.It could be a ten step process, natural selection still acts only on existing life forms either populating, or de-populating, dependent on other factors.
Just because the term is "natural selection", doesn't mean it means only selection! Tell you what, since you have never read Origin of Species, let's see how Darwin put both steps together in natural selection from the conception of the term. I'll bold where each step is:
"If, during the long course of ages and under varying conditions of life, organic beings vary at all in the several parts of their organization, and I think this cannot be disputed; if there be, owing to the high geometric powers of increase of each species, at some age, season, or year, a severe struggle for life, and this certainly cannot be disputed; then, considering the infinite complexity of the relations of all organic beings to each other and to their conditions of existence, causing an infinite diversity in structure, constitution, and habits, to be advantageous to them, I think it would be a most extraordinary fact if no variation ever had occurred useful to each beings welfare, in the same way as so many variations have occurred useful to man. But if variations useful to any organic being do occur, assuredly individuals thus characterized will have the best chance of being preserved in the struggle for life; and from the strong principle of inheritance they will will tend to produce offspring similarly characterized. This principle of preservation, I have called, for the sake of brevity, Natural Selection." [Origin, p 103 6th ed.]
Look at the last sentence. Darwin did not call the struggle and preservation (selection) "natural selection". He called the whole thing, including variation, natural selection.
Don't forget this.....
"“I think that there can be little doubt that use in our domestic animals strengthens and enlarges certain parts, and disuse diminishes them; and that such modifications are inherited”
What I gave you were sources that have the studies using the scientific method.
You've only made general sweeping claims with absolutely no evidence, based on the scientific method, for the 'how' of Darwinist evolution.
Or, in the case of Google scholar, actually are the evidence based on the scientific method. What do you think scientific publications are, anyway? They are the "actual evidence". That you won't even try to read them, but post this denial, shows that you are not interested in reality. If you won't look at the evidence when people point you right at it, then you are trying to peddle false witness.
And yet another example of a wordy generalized claim....but totally empty of any evidence, based on the scientific method, for the 'how' of Darwinist evolution.
Did those links use the scientific method. The ones I gave did. Since I'm not arguing against God, your argument is irrelevant. You did notice my faith, right?
And yet another example of a wordy generalized claim. "The ones I gave did" is nothing more than an empty and baseless claim. Actually post content.
I will give you a few examples.
Sorry, had to snip the study because the post was over the character limit.
Are you suggesting that the study establishes an experiment with absolutely no mutation present and all change was from natural selection?
