The foundation of the theory of Evolution CAN be called a fact. The foundation of the theory of evolution is the fact that allele frequrncies in a population change over time.
I dont believe it can be, and yet according to the evolution theory, it magically happened...somehow.
The theory of evolution says nothing about the arisal of the first life form, it only comes into play after life has formed.
now, im no scientist, but that doesnt sound very scientific to me.
That's becasue you are wrong.
So no one has observed any mutations that have created a new species
You said life-forms, not species.
yet thats how ALL species came into existence...thru gradual 'decent with modification' & 'mutations' & 'natural selection'
It is. Notice how you said gradual. So, you can;t have an entirely new species getting born to a now existing species, that wouldn't be gardual.
So again, the theory is relying on an unproven, unobservable, unrepeatable phenomenon that apparently magically happens...i thought science was about evidence in the sense that it can be 'proven, observed & repeatable?
Again, that's because you are wrong.
Yes your talking about the Urey/Miller experiment from over half a century ago. They did well in producing some amino acids in their flask.
Indeed they did.
But since that time no one, after 50 years of trying, have produced anything any more substantial then that.
You'll have to excuse me for not knowing the exact daetails, but I believe you are wrong, ther have been numerous experiments done, and they all confiremed the Urey-Miller experiment, and even refined it. Like I said I can't provide the details, so you'll have to ask someone else to provide them for you. By no means take my word for it though.
They are still trying to work out how DNA and RNA even work together let alone how they 'evolved'
How DNA evolves is very well known. How it originated maybe not (don;t know about it anyway) but taht has nothing to do with evolution.
yet it magically happened and apparently the (unprovable) primordial soup was responsible for it.
Nothing to do with evolution. Everything pertaining to this has to do with abiogenesis.
/can anyone see why many people do not believe in evolution?
Yes, because they've been told lies about it, and don;t understand what it really says.
However, if you are interpreting 'evolution' to mean gradual changes in a species to provide a great variety within that species, then i can agree with it, because genes do create great variety
What is the mechanism that stops it going over the species boundary?
the parrot family for instance has a huge variety and they proably did all develop into their separate types within that family through 'evolution'
So, would you say the "parrot species" has a different ancestor then the "chicken species"?
Humans too.... such a huge variety exists among us
Actually, we are VERY similar.
Dogs
Horses
Cats
the variety within a species is endless... to me, this is probably the most likely 'evolution' senario
So, why does it stop when getting to the "species level"? In fact, the evolution of new species has been observed, so no matter what you answer here, you're allready wrong.

Re: Occams razor...
Ive spent most of my life struggling with the existence of God.In some ways it would be easier to conclude he aint there.For a fair period of my life i lived it like he isnt.I have an enquiring mind.And believe not to trust everything i read and hear.Im a doubting thomas.Its served me well so far.
So, do you doubt the bible? If not, why not? There isn't exactly much evidence for most of the claims it makes.
Older than 6000 years.Id hazard a guess and say 3- 4 billion years old.By definition im not actually a fundamentalist or a creationist in the strictest sense of the word.I also believe parents have the right to choose whats taught to their children in schools and shouldnt have anything forced upon them that they dont agree with.
So, if parents don't agree with the fact that the earth is round, should their children not be taught this? What about the holocaust? There are people who deny it happened, should their children be taught it didn't happen?
Im not part of any intelligent design movement.I dont read creationist websites as i think they have some things wrong as well,starting with the age of the universe.
May I then ask how you came about your erroneous view of evolution?
Of course.
Then why do you dismiss it out of hand?
But lets be realistic here.
I am.
This debate has participants that are so firmly entrenched in their particular set of beliefs that nothing short of God whupping atheists upside their heads or absolutely irrefutable evidence that there aint a God would change our varying views.
First of all, I hold no beliefs, I base my views on facts.
Second, if there's no evidence for something, I'm not going to call it a fact. If god would have been very clear about his existence, and left evidence everywhere, he could count me in. The simple fact of the matter is, he didn't leave a single shred. Now, when we look to evolution, there's overwhelming evidence for it, despite your denying it. Now I ask you what conclusions should I draw from these two givens?
The evidence would have to be extremely compelling.
It is. The fact you reject it, or don't understand it (evidenced by the fact you called homo habilis a chimp) doesn't change this.
In some ways this website has NOT changed anyones view but has given each sides view an airing anyway.
As it should. It's not the websites fault some people have their eyes closed to The Truth (tm).
I believe there is a God.
What makes you think evolution is not compatible with god? It's perhaps not compatible with a literal reading of genesis. But genesis could've been a lie by men about god. And the writers of genesis are now burning in hell. What makes you think that god and evolution are incompatible?

Re: The theory of evolution contains no magic. That's the "other side's" theory.
Peg writes:
this is very true and i appreciate the point your making here. I've never undertaken any science studies so i'm obviously not speaking from experience.
If you haven’t ever done science, then how can you critisize it?
But its certainly not arrogance that makes me disbelieve evolution.
You don’t know anything about it by your own admission, yet you think you know more? How is that not arrogance?
if anything, arrogance is seen alive and well in evolution with such sayings as ”All competent scientists believe evolution. All intelligent people believe it. Only the uneducated and the ignorant don’t believe it.’
While I do object to those statements, as they have far too much finality to it, they are basically true. So, why should we not proclaim the truth?
This is a form of intimidation and mental bullying, almost being forced to believe it without questioning it
Not at all, question it all you like, but don’t dismiss evidence because you don’t like it, come up with legitimate reasons for it.
even though the theory has changed and there are many different schools of thought.
Of course the theory has changed, so has every other theory out there. Why do you trust the theory of gravity, yet not the theory of evolution? The theory of gravity has changed far more then the theory of evolution ever has. And there aren’t really that many “schools of thought”within evolution.
From what your saying above, only people involved the the study of evolution can understand it.
Of course they’re the only ones who can understand it. How can you understand something you haven’t studied?
If thats the case then surely you must understand why anyone who doesnt study might doubt its validity, because how can they understand something they have not personally studied?
Which is why I keep telling people to study it. Not understanding something is fine, claiming that you do understand it when you don’t isn’t.
Is it even reasonable to expect every person to study evolutionary science?
No, but those that don’t shouldn’t tell everyone that they do uinderstand it.
Likewise, is it reasonable to expect those of us who dont study, to simply accept the results of those who do study?
Unless you want to study it and prove them wrong, why shouldn’t you accept it? Do you have any indication they are unreliable?
this is quite a dilemma, yes? Lol
Not really, no.
im sure evolutionists are as committed to their ideas about the origin of life just as much as creationists are committed to their belief in a creator.
They’re not. If evidence is found that contradicts it, the theory will be changed to fit it, or, if that is not possible, an entirely new theory will be made.
both are a matter of faith if you get to the nitty gritty of it.
No, only creationism is, since it has no evidence for it.
Evolution has not given an answer for the origin of the first living cell or how lifeless chemicals came alive or how genes shape the form of living things .... or how lifeless chemicals came alive or how genes shape the form of living things ....
Which is not what evolution is about. Do you doubt gravity because it hasn’t answered the question where matter comes from?
these are all a matter of faith in that "it must have happened" even though we cant replicate it, or observe it.
Actually, it’s just different studies that occupy themselves with those question, go critisize them if you have a problem with what they claim, not evolution.
for someone like me, who has not studied evolution personally and who believes in a creator, this is a HUGE hurdle.
I can understand, but since you don’t know enough about it, how can you claim it is false?
Also, could the creator not have used evolution to get the result we see today?
On one hand evolution says that all living things in existence came from an original single celled organism or a primordial soup (???) ...or perhaps landed here in the form of bacteria on the back of a metorite...
No it doesn’t, that’s abiogenesis, or in the last case, panspermia.
The odds are infinitesimally small that any of this could have happened.
How do you know?
I dont have to be a scientist to know that life only comes from pre existing life, and yet, if i dont believe in evolution, then im an arrogant uneducated fool.
That also has nothing to do with evolution.
Well you see this is where i dont have a problem with 'evolution'
How can you disagree with something you know nothing about?
as i said im willing to accept that within a particular species, there is a huge variety and its quite reasonable to accept that species have diverged or branched out through 'evolution' aka 'genetics'.
Evolution is not AKA genetics, they’re two completely different studies. However genetics did confirm the predictions of evolution. Further, what would make the changing halt at the species level?
The problem i see in what you are saying is that, the feline at some stage is linked to the hyena... but is that really likely? What is the evidence for such a link?
Genetics.
Even Darwin expressed concern over gaps in the fossil record which failed to produce any transitional links.
Of course, in the 150 years since Darwin, there have been no further discoveries in the fossil record . ..Oh wait, there have been.
Actually the fossil record has shown the sudden appearance of fully formed and complete species over and over again.
Of course, incomplete organisms can’t survive.

Re: The theory of evolution contains no magic. That's the "other side's" theory.
Peg writes:
no, its because evolution is based on the premis that species all decended from a common ancestor
Peg, it isn't based on that. It's based on the fact that allele frequency in a population changes over time.
this implies that it originated from an original source...from a primordial soup where life sprang to life...where simple molecules 'developed' into complex ones, they came to life somehow and developed into all the life we have on earth today.
No it doesn't, that has nothing to do with evolution. Life could've been made by aliens, god whatever you can think of, after that evolution took over.
THAT is why i take exception to evolution.
But it has nothing to do with evolution.
Life only comes from pre existing life...this is fact and all smart scientists know it.
This is wrong, where did the original life form come from, if it can only come from other life?
This is probably why most have steered clear of placing 'origin of life' & 'evolution' in the same sentence.
The reason they steer clear of it is because they are two completely different things.
Perhaps someone should have told Darwin to change the title of his book from 'Origin of the species' to 'Species of Evolution'
But evolution IS the origin of species, not the origin of life.
that would make more sense.
Not really, since evolution IS the origin of all species.
I am happy to accept evolution. Actually i do...to a point... only to the point where the origin of life is involved.
Then you accept it completely, because it has nothing to do with the origin of life.
If evolution insists that each species came from some other species, then this is not in line with what we see in nature.
Yes it is, speciation has been observed, both in nature and in labs.
Each species continues to produce its own kind - in great variety - I accept this and i accept genetics.
But it's not true, as pointed out, speciation has been observed. And a "kind" is not the same as species, or, if it is, new kinds have been ovserved to evolve.
But this crossing of species does not happen.
Yes it does.
They have not successfully cross bred anything of a differnt species, have they?
Why would they need to do that? The definition of a species is organisms that can produce fertile offspring together, if they cant do that they're not the same species. And, to make it even more confusing, two different species CAN produce offspring sometimes, do mules ring a bell?
How likely is it that the amino acids thought to have formed in the atmosphere would drift down and form an “organic soup” in the oceans? The same energy that would split the simple compounds in the atmosphere would most likely decompose any complex amino acids that formed in the atmosphere. Ultra violent light is used to kill bacteria, not grow it!
i've read that there are over 100 amino acids, but only 20 are needed for life’s proteins, yes? And they come in two types, yes?
Now here's the problem, if they formed at random, as in a theoretical organic soup, it is most likely that half would be of one type and half would be of the other type. Yet, of the 20 amino acids used in producing life’s proteins, ALL are of the same type.
the odds of this happening would be like me having a huge jar of blue and red jelly beans, mixing them all up and putting my hand in to pull out a handful that are all the same colour! What are chances of that happening????
All very nice questions, but they have nothing to do with evolution.
Thats pure conjecture. if you look at the bones of many creatures you'll see similarities, it cannot be proved that these bones evolved to produce a new species.
What the hell are you talking about? where does it say that? You see, this is the problem Peg, because you haven't studied evolution, you have all these things in your head that evolution doesn't claim happens, yet you think it does say this. Now, if you don't study it, yet continue to say it says this, you do indeed come off as ignorant of the theory, because basically, you are. There's nothing wrong with being ignorant about something, but when told time and again you are wrong on something, yet refuse to study the subject, it becomes a problem.
In effect, evolution went backward”something that theoretically it is not supposed to do.
How do you know it's not supposed to do that, you haven't studied it, and judging by your comments, you don't even know what it says.

Re: Macro-evolution sans fossils!
Hello Wardog, and welcome back. Just a few quick points. Ask if you want me to elaborate,
wardog25 writes:
Here is the problem with those results when you try and compare them to the evolutionary model: As an example, assume that 10% of the mutations that are passed on are "beneficial" mutations (EXTREMELY generous from the numbers I've seen). That would mean 90% are benign (they give no advantage or disadvantage).
Instead of benign, I'd use the word neutral. Benign means good, yet something with no effect can't be said to be good, right?
{ABE}As Percy pointed out in Message 290 your use of the wrod IS correct. I retract this statement.
Not only does the human body seem almost perfectly designed, it's even organized and symmetrical.
It's far from perfectly designed, nor is it symmetrical.
Why would mutation care about those things?
It doesn't, that's why it isn't. But far from mutation making our body shape, you forget the other mechanism involved, natural selection.
As a final note, I would like you to provide the sources for your statements. As they are now,, they are nothing but assumptions, and all I have to do is say they aren't true, and we're on equal footing again.

surely this statement implies that something 'non-living' came to life.
Yes, if life can only come from life, then it should always have existed, this is abviously not the case, so it must've come from something that wasn't "alive". Whether it was poofed into existence or through chemical processes, it wasn't always there.

Huntard writes:
But evolution IS the origin of species, not the origin of life.
which implies what i said initially, that evolution is about the origin of life.
No it doesn't. What part of "evolution is NOT about the origin of life" don't you understand?
Lets face it, if everything came from something else, then it must go right back to nothingness
That's why I said that life can't just come from other life.
just like the universe...at some point the universe came into existence from 'non-existence'
Not necesarily, but this could be the case, yes.

Re: The theory of evolution contains no magic. That's the "other side's" theory.
how can evolution and origin of life not go hand in hand in light of what you are saying
Because evolution doesn't care how life began, it could've been any way you can think of. God could've done it, it could've been chemical processes, but so far we don't know, and for evolution, it doesn't matter. We do have some indication that chemical processes could be responsible, but not yet a fully developed theory. So for now, I'm sticking with: "I don't know".
I understand that you are saying they are separate issues, one being how species developed/evolved, the other, how life began
Ok, good. That's a very important step.
and yet, if you follow the evolutionary chain, they all lead you back to an original source... what came before the original source?
I have no idea. Nor is it important for evolution. It's likely we will never know what came before, but that we're going to find out how it could've happened. But for now, a definitive answer is lacking. This however does not mean that you can discard evolution any more then you can discard nuclear physics, gravity and a whole bunch of other scientific theories that don't explain the origins of the things rthey are describing, but do describe how these things work.

Peg writes:
thank you huntard,
No problem, here to help and all.
i agree with what you are saying, hence, as i've said before, i accept evolution to a point...to the point of where one species begins and ends
But speciation has been observed to happen, both in the wild and in a lab. By speciation, I mean that descendants from a parent population are unable to breed with other descendants from the same parent population and that they vary genetically. Speciation in bacteria is measured somewhat differently I believe, but I don't know a lot about that.
I think it is also fair that evolutionists should not be so quick as to rule out completely the idea of a universal God/Creator
Perhaps not, but the problem is that there is no evidence for such a being existing.
if as you say, a definitive answer to the origin of life is lacking, then we cannot rule out an intelligent designer altogether.
As the first cause for the original life, no, we can't (yet ). As a cause for every single species, yes, we can.

granted, 'lower' is a bad use of wording ....all life is complicated and amazing.
I should have asked why gorillas and orangutans and monkeys are still around today....why didn't they all evolve?
Because they were perfectly suited to survive in the environment they were in, just like crocodiles, who didn't evolve much either for millions of years.

Hello again Peg.
Peg writes:
perhaps i'm asking for something that does not exist?
Yes. We don't know every single organism that ever lived, and the farther back you go, the harder it is to get the organisms. Especially when there aren't any "hard" parts to fosilize. So, when we get to single cell life, that will probbaly never be found. I of course mean the ancestral single cell life, I know there are "modern" single cell organisms, but they are probably very different from those earliest lifeforms.

That's not ALL evolution is though, again you forget natural selection, that's a very big part of the whole.
thats a little different to the evolution of one species into a new kind of species
No it isn't. Speciation has been observed.
i dont believe that at all because if that were true, then we should be able to replicate it or we should see it
We can't replicate everything that ever happened, as others have pointed out quite well.
Peg, if you want my advice, take Modulous's offer. I think you'll learn a lot from him. Just remember, that evolution happening and being true has NOTHING to do with there being a god or not. It is only contradictory to a literal reading of the bible, which you don't do anyway.

Re: how do we measure 'inferiority'?

what proof do evolutionists provide to support the claim that natural selection chooses beneficial mutations to produce new species?
Proof? Nothing. Evidence however, that's plentifull.
in 1999 a brochure by the National Academy of Sciences (NAS) in America says: “A particularly compelling example of speciation [the evolution of new species] involves the 13 species of finches studied by Darwin on the Galápagos Islands, now known as Darwin’s finches.”
these finche's were studied in the 70's by Peter and Rosemary Grant who discovered that after a year of drought, finches that had slightly bigger beaks survived better than those with smaller beaks. these findings were assumed to be significant apparently because the size and shape of the beaks is a primary way of determining the 13 species of finches.
they estimated that if droughts occur about once every 10 years on the islands, a new species of finch might arise in only about 200 years.
ok so it seems that evolution might have a point with this example
Except that in the years following the drought, finches with smaller beaks again began to dominate the population. In the science Journal Nature 1987 a Peter Grant and graduate student Lisle Gibbs wrote that they had seen “a reversal in the direction of selection.”
So it seems the finch's were not becoming a new species at all but rather the population was being affected by the climate changes.
And what in this is NOT evidence of natural selection at work? First because of the drought the beak size increases, then when everything returns to normal, the larger beaks aren't necessary any more, and they gradually return to what they were before. Natural selection if I ever saw it.
