No.1 Doubt the fossil record.
Darwin’s theory has always been closely linked to evidence from fossils yet do they show the gradual changes that he predicted ?
Yes. Hence all the intermediate forms in the fossil record.
All the quotations out of context in the whole world won't make them go away.
Doubt No.2 Evolution by Mutation
Many scientists have noted that over time, the descendants of living things may change slightly. Charles Darwin called this process descent with subsequent modification. Such changes have been observed directly, recorded in experiments, and used ingeniously by plant and animal breeders. Seems plausible on the surface.
what is the evidence for mutations in evolution?
We can directly observe beneficial mutations occurring and spreading through a population by natural selection.
Doubt No.3 Evolution by Naturual selection
You don't explain what your doubt is.
did the finch's on the golapogolas islands prove that natural selection drives evolution? No they didnt. In the years following the drought, finches with smaller beaks again dominated the population. Thus, Peter Grant and graduate student Lisle Gibbs wrote in the science journal Nature in 1987 that they had seen a reversal in the direction of selection. In 1991, Grant wrote that the population, subjected to natural selection, is oscillating back and forth each time the climate changes. The researchers also noticed that some of the different species of finches were interbreeding and producing offspring that survived better than the parents. So even after all the small beaked finchs had died out, years later, they were back again...what does this show?
As the scientists you quoted said, it shows that the morphology of the finches was subject to natural selection. As in:
Grant wrote that the population, subjected to natural selection, is oscillating back and forth each time the climate changes.
Evolutionary theorist Jeffrey Schwartz wrote in 1999 that "natural selection may be helping species to adapt to the changing demands of existence, but it is not creating anything new.
Well of course not, that's what mutations do. Selection simply selects the best variants, hence the name.

Stuff Not Related To The TOE
Now i havnt even gone into the 'origin' of life debate which, according to science, is highly unlikely.
When did science tell you that? Only I was chatting to science down the pub the other night, and science told me something rather different.
Science told me that it is foolish and footling to try to calculate the probability of an event when you know neither the nature of that event nor the conditions under which it took place.
I'll be happy to add this later...the chance of life spontaneously generating is unbelievably improbably...so much so we could say it is impossible.
Show your working.

Re: Some facts that you may not be aware of
For purposes of debate, can transitionals be shown. Birds for example - are there real-life examples of dinosaurs to birds?
You've made 4032 posts on this forum, and you don't know the answer to that?
Let me give you a little hint.
YES.

im aware of that, but the point is that evolution is said to explain how the great variety of species developed, albeit slowly, and yet the fossil record does not show the supposed changes taking place.
Yes it does: all those intermediate forms, for example.
It shows fully formed and functioning creatures
Yes, of course. Because that's what the theory of evolution predicts that we should see, and the predictions of the theory are always correct.
as opposed to anything in its development stage.
What on Earth are you talking about? "As opposed to"?
Obviously an intermediate form is a fully formed and functioning creature, how else could it be transitional?
regarding the Archaeopteryx, the fossil has perfectly formed feathers and wings that are capable of flight. Also the wing and leg bones are thin and hollow which is what is found in birds today.
It also has gastralia, teeth, independent digits, no synsacrum, a pelvis unfused to its vertebrae, and no pygostyle. Putting it all together together, we find that it is an intermediate between feathered dinosaurs and modern birds.
It does not predate birds, because fossils of other birds have been found in rocks of the same period as Archaeopteryx.
Of course. And not one single modern bird.
Some even think that the animal is still alive today...
But the delusions of creationists are not evidence.
the fossil is apparently very similar to a fox like animal called a Hyrax in Africa.
Did you just call hyraxes "fox like"?
What is it with creationists? You're obsessed with biology, but you're not interested in it.
How long, how frickin' long, would it have taken you to look up the word "hyrax" on Google?
they claim to have found transitional fossils, true. In Darwins day he wrote in Ori/Spec There is another and allied difficulty, which is much more serious. I allude to the manner in which species belonging to several of the main divisions of the animal kingdom suddenly appear in the lowest known fossiliferous rocks. . . . The case at present must remain inexplicable; and may be truly urged as a valid argument against the [evolutionary] views here entertained"
And this was perfectly true in 1859, when he wrote it.
Since then, paleontologists have found masses of intermediate forms.
the Swedish botanist Heribert Nilsson has spent over 40 years in the research field and he wrote in his book 'The Synthetic Origin of the Species' 1953 p.1212
"It is not even possible to make a caricature of an evolution out of palaeobiological facts. The fossil material is now so complete that the lack of transitional series cannot be explained as due to the scarcity of material. The deficiencies are real, they will never be filled."
Granted that this was written in the 50's, but surely with thousands of scientists collecting fossils from all around the globe, they would have found many transitional fossils.
And, of course, they have. And the words of one Swedish non-paleontologist writing in the 1950s whom you've never heard of except that you found his name in a creationist quote mine will not magically make that fact disappear.
I used 'Darwins finch's' as an example because they were said to be a compelling example of speciation [the evolution of new species] but the fact that the population, subjected to natural selection, is oscillating back and forth each time the climate changes seem to be more better explained as the maintenance of adaptation. Whole populations of small beaked finshes died out, yet they came back again decades later! Think about it, the finches didnt go thru an evolutionary change. It wasnt speciation...it was adaption and because the small beaked finches began to be born again, it must have been the genes that was controlling the change, not natural selection or speciation or evolution. The finches did not change to a new species of finch.
That would be why no-one ever claimed that they did.
thats not entirely true
We could not have been created if we evolved. Its one or the other.
You are confusing the proposition that there is a creator with the proposition that he magicked the human species into existence by an act of special creation.

Another Dumb Creationist Quote Mine
A View of Life states: Beginning at the base of the Cambrian period and extending for about 10 million years, all the major groups of skeletonized invertebrates made their first appearance in the most spectacular rise in diversity ever recorded on our planet.(California, 1981), Salvador E. Luria, Stephen Jay Gould, Sam Singer, p. 649.
This is true. Therefore, I am utterly at a loss to know why you quote it.
Paleontologist Alfred Romer wrote: Below this [Cambrian period], there are vast thicknesses of sediments in which the progenitors of the Cambrian forms would be expected. But we do not find them; these older beds are almost barren of evidence of life, and the general picture could reasonably be said to be consistent with the idea of a special creation at the beginning of Cambrian times.Natural History, October 1959, p. 467.
This is laughably out of date and out of context.
Zoologist Harold Coffin states: If progressive evolution from simple to complex is correct, the ancestors of these full-blown living creatures in the Cambrian should be found; but they have not been found and scientists admit there is little prospect of their ever being found. On the basis of the facts alone, on the basis of what is actually found in the earth, the theory of a sudden creative act in which the major forms of life were established fits best.Liberty, September/October 1975, p. 12.
This is out of date, false when it was written, and ridiculous. Which explains why it was written by a creationist for a magazine distributed by the Seventh Day Adventists.
Carl Sagan, in his book Cosmos, candidly acknowledged: The fossil evidence could be consistent with the idea of a Great Designer.(New York, 1980), p. 29.
The way in which creationists ripped this phrase out of context to deceive you about what Sagan was saying should disgust you even more than it disgusts me --- because, after all, it is you to whom they are lying, and it is you whom they are deceiving.
---
Of course the fact that evolution has taken place is consistent with the idea of a Great Designer. That's just what Melindoor's been telling you. That's just what you've been denying.
What it is not consistent with is creationist fantasies.
ETA: Having seen the Sagan quote in greater context, as provided in the posts below, I see that Sagan explicitly says that the fossil record is inconsistent with the God of creationist fantasy, but not with "a designer of more remote and indirect temperament".

Re: peg, your understanding is flawed
Lots of people can't understand a God who would use evolution and death/suffering, and call it "very good".
The death and suffering exist anyway, even if you believe that God magicked them into existence.
That leaves your inability to accept that God might have used evolution. What's that phrase Jesus had about swallowing a camel and straining at a gnat?
In reality, evolution is the only support for atheism ...
Don't be silly. The pain and suffering to which you alluded are excellent arguments for atheism. The fact of descent with modification is not.
... which is why it is dogmatically defended.
This fails to explain why all those theist biologists think you're wrong about biology.
Try again. Why would biologists, irrespective of whether they're theists or atheists, think that you're wrong about biology?
Good luck figuring that out.
You only "allow" a God, if there is an acceptance of evolution, because evolution makes Him look weak and atheism look strong.
One could say the same about naturalistic explanations for thunder and lightning. That won't magically make those explanations go away, nor does it mean that those who advance these explanations are doing so in order to make Thor or Zeus or Jehovah "look weak".
I mean come on, it's entirely obvious.
The eternal cry of the man with all the evidence against him.

the point of Sagans quote was to show that he was acknowledging that the fossil record shows great design.
Except that he explicitly says that the fossil record is "inconsistent with an efficient designer". To pretend that he was trying to make any other point is dishonest.
The design in living things could not have come about by random mutations...
And that is certainly not what he said.
how can we look at the evidence of design, then say its all a result of slow random mutation
that makes no sense. Its contrary to the evidence that we see.
how can we look at the evidence of evolution, then say its all a result of God poofing animals out of the air by magic
that makes no sense. Its contrary to the evidence that we see.
---
And incidentally, what's this "we"? The evidence that we see, says the person who thinks that hyraxes are "fox-like".
You don't study biology. You study creationist quote-mines. Biologists study biology.

Re: peg, your understanding is flawed
the teaching of macroevolution is built upon the claim that mutations can produce not only new species but also entirely new families of plants and animals. But what has more then 50 years of research and experimentation with mutatins produced?
50 years' worth of evolution.
Are you aware that since the 30's biologists in general and geneticists and breeders in particular, tried inducing and selecting favorable mutations to attempt to produce new and better plants and animals?
Of course. This is why we have new varieties of domesticated plants and animals.
Almost all the mutants they produced died or were weaker than wild varieties.
Of course. This is what the theory of evolution predicts, and the theory always turns out to be right.
Wolf-Ekkehard Lnnig, a german scientist from the Max Planck Institute said
A creationist spouted creationist nonsense. So?
if the finches really did develop into a new species, as the theory suggests ...
It doesn't. Don't be silly.

I wasnt trying to pretend anything. He is clearly saying that he sees 'design' in nature.
No. So stop pretending that that's what he said.
and why does he say that?
He doesn't.
It is likely because he is biased towards evolution rather then design...
You're pretending that he says he sees design in all things ... and complaining that he's biased against design?
even though he acknowleges 'design' in living things.
STOP MAKING STUFF UP.
I can see that he is trying to say that the evidence for evolution does not imply a designed species, but thats exactly what the ToE is...its about slow undirected change as opposed to purposful design. He's using evolution to say that life shows something that has come from trial and error because he is interpreting things with evolution as the basis.
That paragraph could have made a whole lot more sense if it had different words in it.

Re: Some facts that you may not be aware of
I was hoping for a progression of species clearly outlining a lineage in part or full. Not particularly interest one species and an argument of relation based on similar morphology. Afterall, humans have eyes, and monkeys have eyes, but what would really convince me on a personal level, is a progression from a dinosaur to a bird, represented in many species. I believe it's fair to expect a few species, where we should expect hundreds.
I don't know how you calculated that "we should expect hundreds" --- like every other creationist who makes a numerical argument, you have forgotten to show your working --- but there are certainly many known intermediate forms between your standard theropod and modern birds. Some names that come to mind are Caudipteryx, Microraptor, Anchiornis, Archaeopteryx, Confuciornis, Hesperornis, Rahona, Iberomesornis, Patagopteryx ... and so forth. There's plenty there if you can just be bothered to look 'em up.

Reptiles are cold-blooded and heavy/solid, whereas birds are warm-blooded and very light.
Apart from the fact that what you're saying probably doesn't apply to all dinosaurs ---
You are arguing that birds can't have evolved from dinosaurs because birds are not the same as dinosaurs.
Do I wake or sleep?
THAT'S WHAT EVOLUTION MEANS. The descendants are different from the ancestors.
Really? no one ever claimed Darwin's finches as evidence of speciation?
except for a brochure published in 1999 by the National Academy of Sciences
A particularly compelling example of speciation [the evolution of new species] involves the 13 species of finches studied by Darwin on the Galpagos Islands, now known as Darwin’s finches.
the article specifically calls darwins finches an example of speciation.
And of course "Darwin's finches" are an excellent example of speciation.
You are trying to confuse two completely different ideas. If you are trying to do this deliberately, then shame on you for a disgusting liar.
If you have not understood the concepts that you are trying to discuss --- then shame on you for not trying to find out what you're talking about.
Shame on you, the person who thought that a salamander was a fish, shame on you, the person who stated that hyraxes were "fox like", and shame on you, the person who is currently posting abject nonsense about the Galapagos finches. SHAME ON YOU for talking garbage about biology without ever having taken the slightest interest in biology or learned anything about it. Shame on you. Shame on you.

Re: don't use quote mines!
if he didnt think there was design in nature, why say "The fossil evidence could be consistent with the idea of a great designer"
to me thats an acknowlegement of design even if he does believe in evolution.
Then I guess if I say that the way my socks keep going missing could be consistent with the idea of a magic sock-stealing fairy ... you would take that as an acknowledgment of the existence of a magic sock-stealing fairy?
If you lie about what Sagan meant, then you are, how can I put this ... lying about what Sagan meant.
It is true that by employing willful stupidity so gross as to amount to a psychosis, you can lie to yourself about what Sagan meant. This does not change what Sagan meant, nor what he said.
And why do you bother? Oh ... yes ... I remember why. It's because there is no evidence for creationism. Therefore, in order to pretend that there is, you have to recite lie after lie after lie after lie about what scientists think, so as to pretend that they said that there's evidence for creationism. This saves you the trouble of producing any such evidence, something that you are completely unable to do.

Re: Some facts that you may not be aware of
thats right because the only testimony of the fossil record shows the sudden appearance of new kinds of plants and animals
That is not true. Stop making stuff up.
much of the fossil evidence is showing something completely different If the process of evolution describe the constant change of living things why are there innumerable fossils found in ancient strata that, like the lungfish, are identifiable with modern species?
Because that is what the theory of evolution predicts, and the theory of evolution is always right.
why are there hundreds of insect fossils found in Mesozoic rocks similar to species of the same insects we have today?
Because that is what the theory of evolution predicts, and the theory of evolution is always right.
Surely evolution cant apply to some fossils but not others. If the theory is accurate, then there should be no exceptions to the rule and yet there are many.
There are none. That is something that you made up. Stop making stuff up.
