I recall having a conversation on this some many years ago on another thread where evolutionists argued that ANY actions of people (including breeder's purposefully choosing) are 'natural' and therefore akin to 'natural' selection.
But what's amazing is how many people leapt in here in the first place to distance Darwin from this tautology - as if they're aware that it's embarrassing
The other night I told an astronomer that the phrase "The Sun is shining in the sky" was a tautology. He scoffed at me and said, "Look up at the sky now: the Sun is not there!"
But I looked at him bewildered. "Surely you see that large bright disc in the sky, same as I do!"
"But why, that's the Moon!"
"No, good astronomer, that's the Sun. Since by definition a Sun is anything that is shining in the sky, the idea that something which is shining in the sky is shining in the sky is a tautology. I'm afraid all your vaunted astronomical knowledge is good for nothing."
He muttered and went away calling me insane. I have no idea why.

Montalban, by
the scientists' own definitions of fitness, less fit traits can outcompete more fit traits.
Of course your own silly definition of fitness makes "survival of the fittest" a tautology, just as anyone with too much time and too little life can make "the Sun is shining in the sky", "all who call on Jesus will be saved", and "anyone who does not believe in evolution is ridiculous" tautological by a suitable redefinition. You have every right to speak Montalbanese; just don't expect your protestations to carry much weight with the people who are actually working hard to do real science.

As for breeding and natural selection, here's a question for you.
You are a pineapple breeder who has discovered a novel gene with two alleles,
dry and
wet that controls the juiciness of pineapples. In a dry region such as Mexico, pineapple plants that are heterozygous (i.e. having one
dry and one
wet allele) produce moist, juicy fruit; but plants with two
dry alleles produce shriveled and shrunken pineapples, while plants with two
wet alleles produce pineapples that are so bloated that they cannot be transported without leaking juice all over the place.
Because pineapples are hard to pollinate manually, you can only control the breeding of pineapples by getting rid of undesirable plants after they have fruited.
What strategy would you use to breed these Mexican dry-wet pineapples, and what genotypic structure do you expect to see in the Mexican population over the long run?
At the same time, when you introduce this gene to pineapples grown in a moist region, such as Florida, you find that pineapples which are homozygous for the
dry allele produce fruit which are just right. Heterozygous pineapples produce bloated fruit, and pineapples homozygous for
wet simply explode when they are ripe!
What strategy would you use to breed these Florida dry-wet pineapples, and what genotypic structure do you expect to see in the Florida population over the long run?
For bonus points, figure out the natural-selection analogy to this example. Hint: it would be completely unethical to actually experiment on the distribution of these alleles in the relevant population.
