How do you define the word Evolution?

Polyploidy sounds like anything but beneficial to an organism. The fact that it can't interbreed with nonpolyploids is sure evidence that it has nothing to do with speciation but only genetic dysfunction. It's absurd for anyone to think for half a second that it could be the solution to the inevitable loss of genetic diversity by evolutionary processes. Oh and it IS inevitable. I've probved it logically dozens of times, but it ought to be provable easily enough by observation and DNA testing of a series of daughter populations.

Besides, if macroevolution is impossible with one genome, how could it become possible with two of the same?

Typo. Should be "proved."

I guess you guys just can't see how laughable the idea is that inability to interbreed is the definition of speciation. The usual situation must be a condition of genetic reduction to depletion which in itself could be the cause of inability to interbreed, just by genetic mismatch, the furthest possible thing from anything deserving the term "speciation." It's really astonishing how you all go on talking about absurdities with a straight face.Oh, and "probed" was a typo, I meant "proved."Edited by Faith, : No reason given.

Sorry, my premises are ironclad and never disproved. Loss of genetic diversity is the necessary condition for evolution of new phenotypes. This is demonstrated all the time in domestic breeding, and although in nature it's often not as streamlined, mere population splits and reproductive isolation bring about the same conditions. This produces new phenotypes by losing the alleles for other traits. The logic is impeccable and the only reason it isn't recognized is the devotion to the false ToE which pretends loss of genetic diversity is not necessary to evolution. Speciation is not macroevolution no matter how the ToE insists that it is. In reality it isn't and can't be. At best it is a new "species" or subspecies or variation of the Kind. Since loss of genetic diversity is necessary to produce it, each new species has less genetic diversity than the last, and after a series of such population splits it's no wonder if ability to interbreed has been lost by simple genetic mismatch. Not speciation in the sense of macroevolution which is nothing but a wishful fantasy of the ToE.As for polyploidy loss of ability to interbreed with other populations is just another form of genetic mismatch. The whole idea of "speciation" as defined by loss of ability to interbreed is sheer absurdity.And again, mutations can only vary what the gene does, they can't produce anything newer than another fur color or the like. To get evolution beyond the Kind would require major changes in the structure, completely new genetic material. Mutations can't do that.Edited by Faith, : No reason given.Edited by Faith, : No reason given.

No, I argue rightly that any additional genetic diversity must be reduced or lost to produce a new phenotype. Evolution requires it.Edited by Faith, : No reason given.

You've observed no such thing. And I define the Kind as the boundary at which genetic diversity has been reduced to the point that no further evolution is possible.Edited by Faith, : No reason given.

If you mean by "overall diversity" the genetic diversity in the Kind as a whole, yes of course, and I point that out when I think of it. My argument is about what happens as necessary result of evolutionary processes, selection and isolation in particular. Evolution is what requires reduction of genetic diversity. All forms of it do, even drift, but I usually focus on the faster versions such as population splits which can occur over a matter of years.Sorry I've missed nothing that would destroy my argument.

No, I'm not leaving them out, I've accounted for them.

No, it IS the selection that produces the new phenotypes. It doesn't matter what the source of the genetic material is. Most of it is built in and not produced by mutations but it doesn't matter. You cannot get a new phenotype unless you lose the genetic material for other phenotypes. This is wlel known in domestic breeding and the same thing has to happen in nature whenever you get a new species from a population split.

That's pure wishful fantasy. The production of new species is a lot faster than the ToE says, and you don't get beneficial mutations at any rate that would make a difference. And if you did there couldn't ever be a stable domestic purebred and the cheetah would long since have been rescued from its genetic depletion. It doesn't happen, it's sheer theory/fantasy.Edited by Faith, : No reason given.Edited by Faith, : No reason given.

Breeding and ring species are excellent examples.

To get the black pocket mice does mean losing the alleles for the light colored ones and vice versa. The same thing happens with the famous moths. The genetic material for the other color is still present here and there in the population so that they can switch back when the selective pressures change. If you're arguing for mutations that show up just in time to save the sinking ship you're talking Lamarck not Darwin.Edited by Faith, : No reason given.

Mostly it's not mutations at all, you're assuming it's mutations when it's nothing but built in alleles in new combinations. Darwin's elaborately varied pigeons were all the result of new combinations of built in alleles.

Breeding has changed since they recognized the dangers of genetic depletion. They used to not worry about it so they could be as extreme as they wanted in selecting for the desired type. Now they incorporate genetic diversity to avoid the most drastic consequences.Ring species have to lose genetic diversity from population to population just as has to happen with developing breeds. New gene frequencies including a loss of traits from the former population bring out the new phenotypes. It can't happen any other way. And since each new population is formed as a daughter of the former population the genetic diversity keeps getting reduced until the last in the series may be just about genetically depleted, and in any case is genetically changed enough to be unable to interbreed with former populations. It blows the ToE to smithereens for anybody who is really thinking.
