Re: THOSE FINCHES
Darwin collected what he regarded as 9 finch species during his voyage on Beagle 1831-1836). These finches were classified as sparate species based on their beak shape, size, colour, feeding etc. darwin's argument sounded so good, no-one bothered to test it by seeing if they were really separate and could not interbreed and produce fertile offspring. Now it has been discovered that Darwins finches can interbreed and produce fertile offspring if given the opportunity, so they are really one species, and provide no evidence for the evolution of new species, and never have. This historic first and foundational evidence for Darwin's theory turns out to be false.
You seem strangely confused about what Darwin claimed about the Galapagos finches.
(1) Darwin did not claim that they were reproductively isolated, or that they weren't: so this is not something that he could conceivably have been wrong about.
(2) Darwin barely mentions the Galapagos finches in the Origin of Species. Here is the complete text of the Origin of Species. If you will search through it, you will find three uses of the word "finch", none of them references to the Galapagos finches. And yet you claim that they were the "foundational evidence" for his theory!
(3) Darwin does however make a passing reference to the "birds of the Galapagos", not mentioning finches or giving any details, in the section of chapter II entitled "DOUBTFUL SPECIES":
The forms which possess in some considerable degree the character of species, but which are so closely similar to other forms, or are so closely linked to them by intermediate gradations, that naturalists do not like to rank them as distinct species, are in several respects the most important for us [...] Many years ago, when comparing, and seeing others compare, the birds from the closely neighbouring islands of the Galapagos Archipelago, one with another, and with those from the American mainland, I was much struck how entirely vague and arbitrary is the distinction between species and varieties.
The fact that these finches, which were classed as separate species by creationist zoologists, can in fact interbreed, therefore proves his point.
---
In addition, there is one error in your post that you could have figured out for yourself, despite your ignorance of Darwin. You claim that "no-one bothered" to check that they were interfertile. Then how do you suppose you know that they are?
All creatures adapt but they don't evolve into another creature. Adaption is the built in ability of living creatures to cope with changes in their environment. The same goes for humans, the different skin colours were all in-built so that the sons of Noah and their generations adapted to the various climates as they spread across the globe.
You don't know much about biology, do you?
Incidently Darwin was still a creationist when he came off the Beagle, but later was influenced by the infamous X-club of humanists.
The X Club was founded in 1864. Darwin published the Origin of Species in 1859.

Re: THOSE Creationists!
Seriously I wouln't discredit Darwin, I believe in Evolution -WITHIN A SPECIES. Dogs have always been dogs, elephants have always been elephants, etc. With all the "millions" of years surely there would be thousands of fossil finds of intermediary forms.
There are.
Never mind human bones, -sorry for going off course a bit but how does population fit an evolutionary timescale.
As your question is off topic, perhaps you would be best advised to use the forum search to find one of the threads in which creationist gibberish about population growth is blown to pieces. It is, in my opinion, in the top three dumbest creationist arguments, and that's saying something.

Re: THOSE Creationists!
Mutations cause the downgrading of a species, not an upward progression and tends to eventually eliminate it.
See Evolution -A theory in Crisis by Michael Denton.
Ten years or so after Denton wrote Evolution - A Theory In Crisis, he realized that he was wrong and admitted it publicly. See Michael Denton, Nature's Destiny:
It is important to emphasize at the outset that the argument presented here is entirely consistent with the basic naturalistic assumption of modern science - that the cosmos is a seamless unity which can be comprehended ultimately in its entirety by human reason and in which all phenomena, including life and evolution and the origin of man, are ultimately explicable in terms of natural processes. This is an assumption which is entirely opposed to that of the so-called "special creationist school". According to special creationism, living organisms are not natural forms, whose origin and design were built into the laws of nature from the beginning, but rather contingent forms analogous in essence to human artifacts, the result of a series of supernatural acts, involving the suspension of natural law. Contrary to the creationist position, the whole argument presented here is critically dependent on the presumption of the unbroken continuity of the organic world - that is, on the reality of organic evolution and on the presumption that all living organisms on earth are natural forms in the profoundest sense of the word, no less natural than salt crystals, atoms, waterfalls, or galaxies.
However, I believe that your nonsense is off-topic --- this thread is for you to be wrong about transitional species. If you wish to be wrong about genetics, start another thread.

Re: Mutation drives transitions ?
Thanks for the detailed analysis, you cannot conclude my evidence as all wrong, as you are biased from an evolutionary viewpoint just as I am biased from a Creationist viewpoint.
There is an old proverb to the effect that the thief thinks that everyone steals.
The fact that you know that you are biased does not mean that everyone else is.
The problem of the incredible complexity of some creatures on the lower branches of the evolutionary tree of life vanishes if you abandon the assumption that they evolved.
The problem is, in fact, solved by pointing out that they evolved. It is not solved by attributing it to magic.
The entire tree of life has been built on the assumption that evolution entails increasing complexity.
What utter nonsense.

Re: Kind of The Point ....
The bits of that which are comprehensible are wrong.
As most of your blunders are too old and stale to have any interest, could you expand on the nonsense in the last paragraph? It's not clear what mistake you're trying to make, but it's possible that it's a new one and might have some entertainment value.
Thanks.

Re: Kind of The Point ....
Your just making the claim that because everyone has a nose then all share a common ancestor with a nose.
No.
I'm talking about actual real anatomical bits and pieces that should be left over from millions of years of endless evolution.
Yet Zilch.
Actually, there's lots of them. In the real world, you know, the one you didn't make up in your head?
As you yourself are about to admit in the case of whales.
Marine mammals are clearly land creatures that adapted to the seas.
so indeed they kept remnants of this reality.
Yet again however evolution believers use these marine mammals as case in point that evolution is true.
in fact it makes a damning case against it.
A case of evolution so undeniable that you yourself admit it ... is damning evidence against evolution?
I have asked you to expand on this. It seems like it could be a whole new kind of creationist crazy.

Re: Kind of The Point ....
Again. The marine mammals show clearly anatomically and otherwise physically/socially great evidence of once having been among the land creatures on land.
So evolutionism uses these few cases to make a greater case of evolution being true and undeniaable.
In fact that was your point.
Yet the few cases prove the poverty of the greater case.
not even 0.01`% of creatures have remnants of past bodies.
This is, of course, not true.
if evolution tries to prove evolution by vestigial bits then it proves its not true by the absence of them.
A line of reasoning.
But not a good one, for two reasons. First, you are simply, flatly wrong about the prevalence of vestigial features.
Secondly, the theory does not predict that everything should have vestiges of everything in its line of descent. What it predicts is that those features which appear vestigial should be consistent with the line of descent (as ascertained by the other evidence). That is, it divides vestigial features into two classes, the possible and the impossible --- it in no way implies that any such feature is necessary.
A challenge to the theory would involve finding a feature in the "impossible" class.

Re: Kind of The Point ....
Yet all other creatures don't seem to have evolved in any way and sure enough they no bits and pieces of foregone bodies.
All other creatures do seem to have evolved and sure enough they are made up of "bits and pieces of foregone bodies".
But these bit and pieces are usually not vestigial because they usually haven't lost function.
If you're descended from monkeys, and monkeys have legs, does that mean that you can or should have vestigial legs? No, 'cos you're still using them to walk on. Whales can have vestigial legs because they're descended from animals with legs and they're not using them.
If you're descended from monkeys, and monkeys have teeth, does that mean that you can or should have vestigial teeth? No, 'cos you're still using them to eat with. Duck billed platypuses can have vestigial teeth because they're descended from animals with teeth and they're not using them.
If you're descended from monkeys, and monkeys have eyes, does that mean that you can or should have vestigial eyes? No, 'cos you're still using them to see with. Blind cave fish can have vestigial eyes because they're descended from animals with eyes and they're not using them.
If you're descended from monkeys and monkeys have tails, does that mean that you can have a vestigial tail? Yes, and you do, it's called a coccyx.
Every animal is composed of "bits and pieces of foregone bodies", but most of these are not vestigial because they are still performing their original function.
The only case in which you could even hope to find a vestigial feature is where there has been loss of function. Even then, at least one of three conditions must be met. Either
(1) The feature still has some function.
(2) The burden on the organism is so slight as to be invisible to natural selection.
(3) The loss of function is so recent that natural selection has not yet removed the feature.
This said, there are of course lots of examples of vestigial features --- but only in places where the theory of evolution predicts that we're likely to find them.

Re: Kind of The Point ....
I'm saying marine mammals did switch from land to sea but not from evolution by selection/mutation.
Rather instant adaptation by innate triggers.
If it was instant adaptation, why are there all those intermediate forms?
Further they are amongst the few creatures showing in their bodies there was a change.
But this is not actually true.
so this makes a case for evolution of having not happened as otherwise all creatures should show heaps or some remnants of previous body types.
See my previous posts.

Re: Kind of The Point ....
Your point is obscure.
Let me reiterate mine.
The theory of evolution tells us which vestigial features are possible under which circumstances, and which are impossible. The theory is always correct. This is evidence supporting the theory.

Exceptio Probat Regulam
It's like you're taking the old saying "The exception that proves the rule" literally. Exceptions don't prove rules, they test them, which is what the old saying originally meant before the meaning of the word "prove" evolved.
No, it's from the Latin legal maxim exceptio probat regulam in casibus non exceptis --- the exception proves the rule in cases not excepted.
For example, if you read that William IV granted the Royal Navy the right to drink the Loyal Toast sitting down, you can (correctly) deduce that the normal thing is to drink it standing up; because there would be no need to single out sailors and say that they could sit down unless this was an exception to a rule saying that people in general should stand up.

Re: Kind of The Point ....
If you say its few then name the percentage relative to fossil/living creatures.!
Well, for example, all mammals possess vitellogenin (egg yolk) genes; only echidnas and duck-billed platypuses actually use them, of course. In non-monotremes they survive as vestigial pseudogenes. So that's 99.82% of mammal genera at a single stroke, with vestigial features in every cell in their bodies (except red blood cells, which have no nuclei).
There are no intermediate forms.
Yes there are. If you wish to deny that they are transitional forms that's another thing, but that they are morphologically intermediate is unquestionable. They therefore constitute evidence for an evolutionary transition.
If you have any evidence for your saltation hypothesis now would be a great time to produce it.

Re: Exceptio Probat Regulam
my point is that creatures do not have anatomical evidence of having once different types of bodies showing a different lifestyle.
And your point is completely wrong.
Yet if evolution was true they should be crawling with bits and pieces.
See post #140.
All the evidence shows that animals are made of of ancestral bits and pieces. But for very very very obvious reasons not all of these bits and pieces are vestigial.

Re: Kind of The Point ....
NO. You can't say egg-yolk genes is a vestigial thing. Who says its not important for many reasons.
Which reasons?
this is about ACTUAL vestigial remnants.
And the genes ACTUALLY exist.
What percentage of living/fossil critters have such vestiges?
I say next to none.
And you are wrong.
If evolution was true this would be impossible .
A billions pieces , at the least, should be counted in the anatomical etc bodies of biology.
Show your working.
There is no evidence for intermediates. Just evidence of creatures in stages interpretated as intermediate. I say they were all living together in different niches. They were all suited. it was quick. Like the Amazon today. Diversity of biology easily accounts for claims of intermediates. So marine mammals are just a part of a living continuim .
You are still confusing intermediate forms and transitional species. There are definitely intermediate forms. This is evidence for evolution, since it is what we would predict in the light of evolution.

Re: Exceptio Probat Regulam
Having a like body plan between creatures is not evidence of heritage.
Yes it is, since it's what that hypothesis would predict.
Its a reality that few creatures have anatomical remnants of previous body realities ...
Well, no it isn't.
But as I have pointed out, it is our expectation that comparatively few of these should be vestigial.
Saying all our bones are repackaged previous body realities is just speculation. Its not proving anything to someone already denying the presumptions.
But saying that this ought to be the case if the ToE is true debunks your argument.
As I said, the fact that you are descended from monkeys and monkeys have legs does not mean that you should have vestigial legs. You should just have legs. The ToE does not predict that every remnant should be vestigial. Most of them should be fully functional, since you can't build a working animal entirely out of vestigial features.
Where are the vestigial bits from such evolution?
In the places where the theory of evolution actually predicts that we should find them.
Why are marine mammals being used to demonstrate evolution when they demonstrate the poverty of it regarding remnants.?
But they don't. Obviously the fact that marine mammals have vestigial features does not in any way imply that (for example) platypuses don't.
