No, natural selection isn't a two step process.
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 only acts on an existing life form, it doesn't create new ones.
Natural selection
transforms existing species into new species. Over the course of generations.
The willy-nilly part of Darwinist evolution is random mutation.
Deer aren't born with longer or shorter fur because of natural selection. The longer or shorter fur was the result of random mutation and after that natural selection either populated, or de-populated, the deer with the longer or shorter hair.
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.
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.
It won't unless random mutation 'creates' deer with shorter fur. Without the 'creation' by random mutation, there's nothing to natural select.
Which is why natural selection is a 2-step process. 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.
I've heard this claim hundreds of times now. Not a single time has evidence been offered, based on the scientific method, for Darwinist evolution. 100% of the time it's been empty claim after empty claim...such as yours. Simply saying "the proof is out there" is worthless without actual evidence.
What I gave you were sources that
have the studies using the scientific method. 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.
LOL. Links are evidence? Well, I have (per google) 45,800,000 links which prove that God exists.
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?
I will give you a few
examples. But they are a molecule in the bucket compared to all the evidence out there. It won't make any difference to you, because you have already demonstrated how dishonest you are. But they may be interesting to the other readers.
New species by natural selection (in the lab):
G Kilias, SN Alahiotis, and M Pelecanos. A multifactorial genetic investigation of speciation theory using drosophila melanogaster. Evolution 34:730-737, 1980.
The experiment tested whether speciation happens due to natural selection or the neutral theory. The neutral theory of speciation states that a new mutation establishes the species, and then the environment changes the new species. Natural selection says, of course, that changes in a new environment due to natural selection will produce a new species. Species here are populations that don't freely interbreed and, when they rarely interbreed, the hybrid offspring have lower sterility and survivability in the environment than the parent species.
They captured 600 parents from a natural population in Cephalonia, Greece The population was expanded in the lab and then split into separate populations:
1C was kept at 18 degrees C and 43% humidity for the first two years and then at 14 degrees C and 43% humidity for 3 years. (the natural temperature in Greece was 25° C. So this is 40% lower temperature.
1D was kept at 25 degrees C and 90% humidity all 5 years.
These populations were fed cornmeal-sugar-agar. 1D is thus the control population in terms of temperature.
2C was given bread-agar and 2D given meat agar. Both kept at 25 degrees C and 90% humidity. Notice that the normal diet is cornmeal-sugar agar.
Each population started at 300 breeding pairs but was kept at about 1,100 individuals.
Drosophila have a generation time of 1 week. At the end of 5 years (2600 generations) 12 virgin males and females from each population were put in mating chambers and mating observed. Fitness measurements were number of eggs, number hatched, F1 and F2 fitness to live in the various environments. Nine enzymes controlled by single genes were studied by starch gel electrophoresis. These are common metabolic enzymes and I can give the names if required.
Also at the end, then went and caught more native flies from Greece as another control. IF neutral theory is correct, then 1D would be a separate species from the new caught flies.
RESULTS
Flies exhibited a tendency to mate with only those flies of the same population. The exception was 1D, which mated with fresh caught flies from the wild (there goes neutral theory). The tendency was not due to chance. Thus, flies from a common gene pool but kept in different environments show sexual isolation. (Mate preference is one of the isolating mechanisms of new species.)
There was significant reduction in F1 hybrid sterility. That is, taking F1 hybrids from 1C and 1D and breeding them with either 1C or 1D shows a high rate of sterility. The F1 hybrids can't get pregnant or cause a female to get pregnant. When F1 and F2 hybrids are placed in the special environments, their viability drops to only 15% of that of the parents in that environment. That is, the hybrids can't survive as well. However, the F1 hybrids from 1D and the new caught wild flies had no reduction in hybrid sterility or viability.
When the genes were analyzed 4 of the 9 genes were the same in all populations. The other showed a genetic difference of 3% between 1C and 2C, 1D and 2C, 1C and 2D, 2.5% between 1C and 1D. Note that the difference between the same genes in humans and chimps is < 1%.
CONCLUSION:
Three new species of flies evolved due to natural selection. Each of them had
new capabilities absent in the parents. One was a species that can live in a much colder climate. The other 2 now have new diets. So 3 species
never seen before. I suggest you remember the title of Darwin's book:
Origin of Species.
