can you explain how an organ that has 'lost its original function' is still useful...what do you mean???
For example, ostriches still use their wings for balance in running like we use our arms, even though the wings have lost their main function of flight.
Or consider blind cave crabs. They lost their eyes, but retain their eyestalks. Which are not completely useless, because if they lost their eyestalks they'd have a couple of holes in their heads.

the tonsils used to be routinely removed because they were believed to be vestigal.
What are they supposed to be vestiges of?
But in more recent years it was discovered that they actually play an important role in the immune system.
No.
Unlike other organs of the lymphatic system, the tonsils themselves are not proven to act as part of the immune system to help protect against infection. Some believe them to be involved in helping fight off pharyngeal and upper respiratory tract infections, but there is no conclusive evidence to that effect.
Even if they play a role, it can hardly be an important one.
Just because we dont know what an organs function is, does not mean that it doesnt have a function. Its just that we havnt learnt what it is yet.
It does imply that it must have a fairly minor role. If you can routinely cut it out and detect no effect on life expectancy, it can't be doing much.
Anyway, organs of the body are the area of doctors and medical scientists...evolutionists should leave them alone in my opinion.
I don't think we should ignore any evidence.

They are in the list of vestigals though as the the New World Encyclopedia states
What you need is a scientist stating that they're vestigial, and what they're vestiges of. Show me an organism in which they perform a much more important function than they do in humans, and then perhaps we'll know that they're vestigial. Prove, for example, that their homologues in monkeys are absolutely vital to the immune systems of monkeys.
What you have is an unsupported statement in a wiki for Moonies. The fact that a bunch of creationist loonies wish to deny that it's vestigial doesn't actually prove that it is.
The original concept was used as an evidence for evolution as my link above shows
Your link explicitly states that what you are pretending was "the original concept" was not, in fact, the original concept.
Peg writes:
The New World Encyclopedia writes:
He also made the important distinction in The Origin of Species (1859), that if a structure had lost its primary function, but still retained secondary anatomical roles, it could still be described as vestigial.
Did you not bother to read it?
Yet as more research went into these organs it was found that many of these 'so-called' vestigial organs were actually still functioning and served useful purposes.....so they go and change the meaning of what a vestigial organ is to mean an organ that can still be used in some minor way to what it was origiinally used for.
But this is absolutely untrue.
An organ serving for two purposes, may become rudimentary or utterly aborted for one, even the more important purpose, and remain perfectly efficient for the other [...] Rudimentary organs [...] are either quite useless, such as teeth which never cut through the gums, or almost useless, such as the wings of an ostrich. --- Darwin, Origin Of Species, Chapter 14
Ever since Darwin wrote the Origin Of Species evolutionists have been talking about exactly the same thing.
It is creationists who have been desperately trying to change the subject under discussion just like they lie about and distort every other concept in evolution.
---
Has it ever occurred to you that if there was really something wrong with the concept of evolution, then people could discredit it without lying about what it is?

This is actually a fair question. I think the trouble is that, while the non-functionaltiy of the structure was the basis of the definition of the word vestigial, ...
But it wasn't. (See my previous post.)
So, while the term vestigial is probably semantically inappropriate ...
But it isn't. A vestige of something is a remnant held over from the past, but not necessarily a completely functionless one. For example, the House of Lords would properly be called a vestige of the feudal system, but that doesn't mean that it doesn't do anything at all.

the list of vestigials that included tonisils was first made by a german anatomist Robert Wiedersheim as that new world encycolopedia article states.
Why do you think that what you just said is true, or that Wiederschiem was competent? Remember that the "New World Encyclopedia" is the Moonie alternative to reality.
Let me say again. If you want to prove that tonsils are vestigial, show me evidence that tonsils are vestigial.
They may very well be vestigial. But I want to hear it from scientists rather than Moonies.
I know that was a long time ago, but the point is that he based his data on Darwins ideas
Well, that's obviously not true. Darwin never mentioned tonsils.
and for a very long time the tonsils WERE considered usless because the scientific community accepted it...
And still no-one has found an important function for the tonsils.
But the mere fact that the tonsils appear to be useless does not prove that they are vestigial.
PROVE TO ME THAT THEY ARE VESTIGIAL. Some creationist babbling out unsubstantiated nonsense does not prove that tonsils are vestigial. PROVE that they are vestigial or shut up.
So this is the foundation for the whole idea of vestigial organs...
No, your gibberish and your quotations from people who think that Sun Myung Moon is God incarnate do not constitute "the foundation for the whole idea of vestigial organs".
Ihowever that does not make the whole vestigial theory true....it actually makes it worse because it contradicts the idea that these organs are leftovers.
Of course, this is not true.
If you will try to argue for this insane point of view, I shall put up a counter-argument. But if you just wish to spew out this insane drivel, then I can do no more than point out that it is wrong.
This is of course nonsense. And also it does not answer my question.
My question was, and still is, this: If there was really something wrong with the theory of evolution, couldn't creationists point it out WITHOUT LYING about the theory of evolution? If the evidence from vestigial features is no good, then couldn't creationist say so WITHOUT LYING about what biologists mean by "vestigial"?
Couldn't you guys prove your point WITHOUT LYING?

I gave you the name of the man who first listed them among the vestigial. His book was called The Structure of Man: An Index to His Past History'
no one is making it up. Perhaps you need to read a bit of the book to see that no one is lying....i've linked it for you.
No you have not.
Did you even look at your link?
You have linked to one page of a review of the book.
You have not linked to the book.
What you have not done is prove that the tonsils are vestigial. Before I believe that they are, I want proof.
And the page i've linked makes mention of darwins book 'decent of man' as a reference, not to tonsils but to the whole vestigial organ theory that Darwin proposed as evidence for evolution.
And you must now know perfectly well what Darwin meant by rudimentary organs.
Now prove that the tonsils are vestigial.
they play a role in the immune system...its been researched and the medical opinion is that they are a part of the working immune system.
Perhaps they play a minor role, though that has not been proved.
I'm not claiming they ARE vestigial. Im pointing out that many of the organs first identified vestiginal, have been proved false....the tonsils being one of them.
And you have no evidence whatsoever for what you claim to be "pointing out". Not a scrap of a shred of a scintilla of a shadow of evidence.
And we know that the tonsils play no important role in humans. So the only open question is whether they are vestiges of something that was important ancestrally. PROVE TO ME THAT TONSILS ARE VESTIGIAL.
if i'm lying, read the book
Which book?
The only link with which you have provided me is one page of a review of the book. Which does not mention tonsils at all.
IF YOU WANT TO PROVE THAT TONSILS ARE VESTIGIAL, THEN PROVE THAT TONSILS ARE VESTIGIAL.
It's a perfectly straightforward request that any biologist claiming that tonsils are vestigial would be able to answer. Because they wouldn't claim stuff before finding out about it.

And im not trying to prove that tonsils are vestigials...my argument is that they are NOT vestigials because modern medics are beginning to understand their function.
But:
(1) You have not quoted one single scientist saying that they are vestigial.
(2) You have supplied no evidence that they have a function.
(3) ABOVE ALL, as I have explained, and as the creationist site that you quoted explained, vestigial does not mean without a function.
they play a role in the immune system...is that system not important?
The immune system is important, but obviously the role of the tonsils in that system is not important.
you keep saying that but im not trying to prove that they are.
But would you at least try to prove that someone thinks that they are? Show me some scientist explaining why they're vestigial, and I might believe that they're vestigial. Or refuse to show me any scientist explaining why they're vestigial, and I won't believe that they're vestigial.
But you seem to want to have your cake and eat it. You want to say that scientists (whom you cannot quote) say that tonsils are vestigial, and that scientists (whom you cannot quote) say that they aren't. And so much for science, because it's been conclusively disproved by science.
