Haha, thanks for the laugh! You clearly don't know what you're talking about thumbsup.gif
laugh.gif I must agree laugh.gif

Thanks pyramidial for a good early morning laugh, helps to wake up laugh.gif If you really want to I will explain natrual selection to you in length and in detail but there's nothing really to say that hasn't been said already...One thing is for sure though, it does not imply intelligence in any way, it is not an active or conscious process, it just mean the organisms that are better adapted (say they have longer necks so can get to food easier or have an anatomy which enables them to run faster to escape predators) have greater chances of surviving and therefore reproducing, passing their genes onto the next generation resulting in the evolution of certain traits that are beneficial for the organisms survival.


You have misunderstood.

I never said NS implied intelligence; we know the concept is billed as blind and mindless. What I said was that selection is a synonym for intelligence since it takes some kind of intelligence to choose. Therefore, **natural** selection is a logical impossibility because the same has no mind or intelligence. Darwinists do the selecting for nature since it is not alive and has no mind. IDists credit the Landlord.

religion results in blind following, you follow what your tolod and don't question, yet those who did are the reason that we have what we do today. natural selection is the weeding out the week and sick so the strong adn healthy can continue to reproduce and make a species succesful. really i have nothing to say frogfish already hasn't. if you think my witing skilss are bad,wah, then obviously your private cristian school is poorly educationg you, i can write, but don't care about spelling when on the computer, and had you gotten a good education, you would have known what the hell you're talking about.

The word 'selection' has a unique definition for use in the field of biology, you can look it up if it bothers you so much.

Not that it matters at all, it's just a pointless matter of semantics.

No i think you misunderstand the concept of natural selection. Nature is NEVER assumed to make choices,it is assumed to be 'blind and mindless' all the way through, hence there is no 'logical impossibility', noone makes any decisions, natural conditions determine which organisms survive, there is no element of choice anywhere in the entire concept. You are arguing on the base of a word you think is wrongly used, that does not mean the process does not exist, that is like arguing someone wrongly called a mouse an elephant, therefore it does not exist. Do you see the flaw in that logic?
Darwinists do the selecting and defy nature? Can you elaborate, how and what exactly do they select? And why do they defy nature?

I see evolution as "intelligent design". It is almost as a guiding hand is in it's process. Sort of like a "leveling drift" in genetics with a "Driftmaker" behind it.
Just my opinion. Nobody has to agree.

the name doesn't define the meaning. all your arguments so far have only showed a blind following to creationism and a lack of thought about your argument, truly a case agianst "intelligent design" in itself.



and its not just your culture, just about all the fossils are dated before 6,00 years old. not includin the rocks and stone tools of cavemen and the micrawaves that , in theory, are reminents of the big bang itself, nt saying its not real (i am just saing that the big bang is a theory) way to much evidence supporting evoluiton to even leave the posibility of creationism. now i ask you, what do you say to that? that yes natural seletion is impossible, okay, then continue to ignore the logic of others that do not believe in waht you do just like the cristian church has been doing for hundreds of years.

See the way, I figure there are so many different theories and religions on how to be 'saved' if I choose the wrong one, seeing there is ONLY ONE TRUE WAY, I'll be bummed anyway, so I'd rather believe in reason and facts than blindly following a couple of old books and stories that might as well be fictional thumbsup.gif

In answer to your questions
1) I never said they where unsuccessfull, but it likely when all life was unicellular there would be a much greater level of competitive pressure on the organism.

This is speculation and cannot be tested... a nice bed-time story.
QUOTE
2)Predatation, competition, mutation within colonial organisms or during reproduction.
3)Because they arn't dying out and are everywhere, literally everywhere.

Are you saying that at present there isn'tt one condition on earth that is suitable for multi-cellular organisms to evolve from single-celled organisms, even when you nor anyone else know what these conditions are.
Nice-bedtime story with a touch of circular reasoning...
QUOTE
4)See 2). They are well adapted to there environment and they are everywhere, we can not observe all of them either. It may also evolve into a different species of unicellular organism. It could be that a multicellular form is not as advantagous. This would mean if it did evolve it would not survive. I'm not this is empirically testable however, as I stated early evolution is not a fast process so testing such a theory would be a very long and difficult thing to test.

So at present this is a nice story to tell without any factual basis...

QUOTE
Could I ask what niches are available to a unicellular organism if it became multicellular, I could probably guarantee that the niche is in fact not available.

Ditto 3-billion years ago... An attempt at circular reasoning?

QUOTE
why do they change? becsue of competition! becouse if they don't they will not be a successful species, becsue if they don't there species will go extinct, THATs why animals evolve, THATis why there are so many chiclids in lake Tanganyika! you want proof? that lake is living proof of evolution! chiclids are evovling SO fast, we can't even count them, in 100 years, so many new specises have evolved, they evolved to fast to study! nowm where the hell is my 250 grand?hmmm? anyone?

Are you saying competition is less now than 3-billlion ago and that that is the reason why single-celled organisms are not evolving into multi-cellular organisms at present? Can't see how anybody can prove this... Otherwise I would classify this as circular reasoning.

There is absolutely no proof that those Ciclids evolved/adapted because of random mutations. Phenotypic plasticity is probably what happened seeing that it happens so fast. Meaning it is only a reshuffling of active and inactive genes, which is only adaptation. Don't count on them adapting to get wings, lungs or feet anytime soon or the next billion years... You will need new information in the genome for that, not reshuffling of the genome. Can anyone provide an example of an animal gaining new genetic information (not a loss of function) through random mutation, it would be really interesting to study?

QUOTE
Brand new information about what could have influenced the evolution of multicellular life! http://www.plos.org/press/pone-02-02-janhunen.pdf

Nice article. However after reading it I can't help but get the feeling that it is entirely based on speculation. "Could"ť (3 times) and "probably"ť (7 times) are not words that one often sees in cancer research and medicine articles, and when these words are found, the assertions are testable in vitro or in vivo. Imagine an anti-cancer drug probably working but there is no way to verify its efficacy; no-one would buy into that theory.
The theories presented in the article can only be verified by finding life on planets with slightly more massive and short-lived stars. At present I don't buy into this theory and one shouldn't proclaim it as fact. A nice exercise for one's imagination and story-telling ability, the article seems to be pushing for funding to look for life in planetary systems with short-lived stars. A waste of money at the present moment (in my opinion) because it is untestable and cannot be verified (by all means try to make it a testable theory). Maybe test in future when star-travel is possible.
So at the moment I would classify this as a nice bed-time story.


QUOTE
Evolution can only work with what is already there

How did it get there in the first place?
QUOTE
it takes great expanses of time for something to evolve so far that it no longer resembles it's ancestor and even then you will usually still have vestigial features that they inherited from their ancestors.

Any vestigial features in humans you know of?

QUOTE
Possible exceptions, random mutations that change the animal drastically but are favourable and are maintained in the population as this individual now has an adaptive advantage and hence gets to reproduce more successfully but even then, an animal does not change into something entirely different.

Any example of this happening? Not looking for a loss of function as result of mutation, those are the only examples I can find.

Your wrong pretty much all the way through there.
You don't understand evolution, you answers show that, go check it out properly. Evolution is not just an over night thing. It takes a very long time, even a "fast" evolution takes a long time. Evolution is scientific theory becuase it is testable, if you choose to be ignorant that is your problem.

Yes and we have new so many ciclid species from just phenotypic plasticity, that would not lead to changes in diet, feeding pattern size, etc. Why would fish develop wings, lungs etc are you just trying to show your lack of comprehension towards evolution and ecological niches and competition?

And when life started there where niches that where ecological niches that where not filled, hence animals that could adapt to take advantage of these did and evolved after time into new species.

I won't bother with a link because it is clear you will ignore it because it might show your wrong (oh wait I bet your expert in biology and hence know far more about it than those who study this!)

Do you have a wisdom teeth to creat dentist?

Quote from: MacGregor, A.J., 1985. The Impacted Lower Wisdom Tooth, Oxford University Press, New York, p. 3.
QUOTE
Evidence derived from paleontology, anthropology, and experiment indicates very convincingly that a reduction in jaw size has occurred due to civilization. The main associated factor appears to be the virtual absence of inter proximal attrition, but initial tooth size may have some effect. Jaw size and dental attrition are related and they have both decreased with modern diet. Jaws were thought to be reduced in size in the course of evolution but close examination reveals that within the species Homo sapiens, this may not have occurred. What was thought to be a good example of evolution in progress has been shown to be better explained otherwise.

Maybe dentists evolved due to civilization... w00t.gif

2) Are you saying that the colon is also a vestigial organ only to give us colon cancer? The human appendix have bona fide functions.

QUOTE
Do you have a tail bone for fun?

3) No, several muscles converge from the ring-like arrangement of the pelvic (hip) bones to anchor on the coccyx, forming a bowl-shaped muscular floor of the pelvis called the pelvic diaphragm. The incurved coccyx with its attached pelvic diaphragm keeps the many organs in our abdominal cavity from literally falling through between our legs. Fun hey...

Firstly evolution in microorganisms has been observed, it has even been observed in Drosophila spp. Artificial speciation in Drosophila
This is not phenotypic plasticity, this is evolution forming an man made species. Done by selective breeding. Same can be said about the domestic sheep Ovis aries.
Evolution speeds up during mass extinction events. In micro organisms. The development of anitbiotic resitance is a form of evolution and has been shown in many bacterial species. Adding antibiotics to bacterial populations has a similar effect to a mass extinction event on a small scale. How to test and observe this, you look down a microscope. - Look at google scholar or pubmed for plently of papers on this.
Speculation does not have evidence, the is an overwhelming amount of evidence for evolution and speciation. I never said it was known exactly however.
Why would a cetacean develop fins, better for swimming and there are vestigal features of the animals skeleton that show this as well as DNA barcoding that clearly links them to there nearest relatives the Artiodactyla, the family, which include goats, hippos, pigs etc. There are also clear corolations between Sarcopterygii fish and tetrapods. This shown within the fossil record and again through DNA barcoding. Such things are seen through developmental biology and the vestigal features shown on developing embryos of many species including us.

FYI vestigal features don't have to have no purpose currently, however it is fair to say that you wisdom tooth article continues to show it is a vestigal feature because our behaviour as a species has evolved and the has not been any use found for a human appendix yet. The coccyx may support muscle but it is still the vestage of a tail.

Maybe creationists can provide you with a theory just as plausible as evolution's magical abiogenesis. There isn't a lot you can prove in evolution theory that happened millions of years ago, except look at skeletons. I think the comment from the evolutionist Lord Solly Zuckerman some time ago about anthropology will make you think and start not to blindly believe: “...it is legitimate to ask whether much science is yet to be found in this field at all.".

Antibiotic resistance is a form of adaptation by the bacteria, whereby mutations occur in the DNA leading to bacterial proteins that cannot interact with the antibiotic and the bacteria survive. The altered protein is less efficient, as a result of mutation, in performing its normal function and in an environment without antibiotics, the non-mutant bacteria are more likely to survive because the mutant bacteria cannot compete as well. No new information is added as is required in evolution of molecules to man.
We are currently struggling to get rid of a Penicillin/Streptomycin bacteria in our cell cultures. Evolution theory isn't helping here, just good old science.

Really who does not believe evolution/adaptation? It is all around us. Just more observable evidence is needed to prove the extrapolation that everything came from molecules. It is funny how creationists and evolutionists agree that all organisms adapt, but creationists choose to believe that everything was magically created and then adapted, and evolutionists believe that everything magically came from molecules, magically became more complex and then adapted.

Wrong, this would not form a new species. Looking different is not the same as speciation. Polar bears btw have have hair like fibre optics, their colouration represents there environment around them, their hairs is actaully not coloured at all.

Erm DNA barcoding is science. Hence it is used in scientific papers and is used in phylogenies of animals as used by the IUCN. Not all scientists may like it, that does not however stop it being scientific. Iti is not speculation however, it is provable and repeatable.

What is the function of the appendix in humans then? Vestigal feature can still have function as previously stated. As regards to that statement a change because a change in lifestyle IS STILL EVOLUTION AND STILL MAKES THE WISDOM TEETH VESTIGAL.
Evolution does not claim molecules magically became complex and adapted, it shows a mechanism for speciation through things we know, like genetic drift. mutation, reproductive isolation.
It has been proven that you can make naturally occuring amino acids. Which are a basis for biological organisms.

Maybe a barking neutron with two electrons less than a fruit-basket decided to give amino-acids a conscience so that they willfully decided to replicate and form functional proteins just for the heck of it, and then life randomly started.

Vestigal feature can still have function as previously stated.

With reasoning like that, i might as well reason that my nose is a vestigial structure as well.
From http://www.talkorigins.org/faqs/vestiges/a...#misconceptions with a few modifications.

How would we know if the nose is not vestigial?
Whether the nose has a function of some sort or not has no direct bearing on whether it is a bona fide vestige. However, at least three possible observations would help negate the conclusion that the human nose is vestigial, using either the evolutionary or the typological definitions of vestigiality:

(1) if the human nose were actually as well developed as, say, the nose of a prosimian or New World monkey; Nope, its vestigial
(2) if the human nose contributed significantly to smell recognition during mate selection; Nope,not as much as in prosimian or New World monkey, therefore it is vestigial
(3) if we could demonstrate via phylogenetic or systematic methods that the human nose and other primate smelling apparatus were not structurally homologous as side branches from the face. Nope, can't, therefore it is vestigial

An additional possible observation would contradict the conclusion of vestigiality by the evolutionary definition:
(4) if phylogenetic methods indicated that no predicted ancestors of humans ever had a large adapted nose for smelling purposes (i.e., that a large, smelling apparatus is actually a derived primate character, not a primitive one). Nope, haven't sen that before, so there you have it, the human nose is obviously a vestigial structure according to sound evolutionary definition.
Pfff, laughable.

Another study found that 84% of patients with leukemia, Hodgkin's disease, cancer of the colon, and cancer of the ovaries had an appendectomy, while only 24% of healthy individuals in the study had an appendectomy.

The function of the appendix was never to break down plant matter (cellulose specifically) as it can't do that. Only bacteria can digest cellulose. You won't find any cellulose digesting bacteria in any appendix, doesn't matter which animal, as the secretion of antibodies from the appendix targets the cellulose digesting bacteria. You are confusing it with the large cecum in herbivores, which do not have an appendix. Chimpanzees do not have an appendix, yet evolutionary postulations would have us believe that a tailed mammal without an appendix gave rise to a (common ancestor) monkey with a tail but still without an appendix, which then gave rise to an ape without a tail but with an appendix, and then on to man where the appendix is supposedly vestigial but with well characterized functions. Is coming or is it going?

If you base your philosophy on life on a theory then you are probably on shaky ground.
How are you going to falsify the theory. If you are unable to falsify the theory then the theory isn't very scientific.

Scientists are starting to understand intracellular mechanisms with great detail with the help of RNAi, DNA microarrays and proteinarrays. All of which are observable, repeatable and testable science. You really can't observe, test or repeat conditions that supposedly happened millions of years ago. You can try but without 100% accuracy, and you will never really know how big your margin of error will be when you do try. That is not science, but educated speculation. That is just another way of saying "Brilliant story man...!".

Well first of all lets get all our apples and oranges in the correct baskets here.

Severe intrauterine growth restriction with reduced uterine blood flow was diagnosed at 21 weeks and intrauterine death occurred at 24 weeks of gestation. Postmortem examination revealed a 4-mm caudal appendage which contained no vertebrae on radiography.

This so-called "human tail vestigial" is actually a dorsal cutaneous appendage as a result of defects of closure of one or more vertebral arches, which may be associated with malformations of the spinal cord, nerve roots, congenital fibrous bands, lipomas, and congenital cysts. It is a defect in development, not a return to our "ancestral form", and is a marker for spinal dysraphism.
Donovan DJ, Pedersen RC. Human tail with noncontiguous intraspinal lipoma and spinal cord tethering: case report and embryologic discussion. Pediatr Neurosurg. 2005 Jan-Feb;41(1):35-40.
The so-called "tail" during development actually has a function. During development, the spine is at first longer than the body because the muscles and limbs do not develop until they are stimulated by the spinal nerved. So the spine must grow and mature enough that it can send out the proper signals for muscles, limbs, and internal organs to begin their growth. For this reason, the spine at first is bigger than the limbs, but later the arms and legs become largest. It is therfore not a useless "vestigial tail".

What about body hair and male nipples?

Exactly how does evolution explain male mammal nipples? According to evolutionary theory, the male/female differentiation evolved much earlier than mammals are supposed to have evolved from reptiles. That is, there were allegedly already males and females long before females evolved breast-feeding. Incidently, male nipples have a function during development. Mammalian embryos contain characteristics of both sexes at first, because they all have basically the same genetic information, and this information is expressed as efficiently as possible as the embryo develops. For example, in all human embryos, at first both the müllerian duct system (female) and the wolffian duct system (male) develop, because both sexes have the genetic information for these structures (a features creationists term "design economy" and "efficient embryological development"). The subsequent differences are the result of designed chemical signals that control the expression of the information. E.g., a gene set usually found on the Y chromosome controls the levels of testosterone and dihydroxytestosterone (DHT) secretion. Above a certain level, these hormones suppress the development of the müllerian duct system and promote the wolffian duct system, so the embryo takes on masculine characteristics. Below a certain hormone level, the opposite happens, and the embryo takes on female characteristics. Male nipples respond to these higher levels of androgens. Nipples aren't evidence for evolution (how does evolution explain it?) and not evidence against creation.

According to evolution theory, human hair is useless and humans won't have hair in a few generations as it is vestigial and useless.
However:
Human body hair, which covers almost the entire body, has a functional advantage over other mammal hair in that it has a high degree of touch perception, which occurs when a hair is moved or bent.
Hair on top of your head covers the spot where about 40% of heat dissipates. Fine body hair also plays an important role by extending the boundary layer, preventing excessive skin loss.
When you perspire, or sweat, the hairs grasp the sweat and keep it near you. This will keep your body cooled.

There is no consensus on what the atmosphere was like 3 billion years ago. Some say oxidized form, some say reduced form. DNA does not replicate by itself... You are right, it does replicate itself through a very complex mechanism that does need RNA, DNA, proteins and a temperature and pH regulated environment.

My thoughts on the origins of life:
Science tries to explain origin of life in a naturalistic manner, but can't at the moment (abiogenesis), although it is believed that the fossil record points out that it is a given, which is not scientific.
Creationism explains life as the result of purposeful design created by a creator. Non-naturalistic, although as indirect evidence they will point to the genetics as a code and that all codes requires a creator, as well as as irreducible complexity. Some creationists believe that the fossil record also prove creationism, and that it is just a matter of interpreting the evidence in the "correct" manner.
Both belong to the realms of philosophy at the moment in my opinion.

For the moment i like science.

It is a defect in development, not a return to our "ancestral form", and is a marker for spinal dysraphism.
Donovan DJ, Pedersen RC. Human tail with noncontiguous intraspinal lipoma and spinal cord tethering: case report and embryologic discussion. Pediatr Neurosurg. 2005 Jan-Feb;41(1):35-40.
The so-called "tail" during development actually has a function. During development, the spine is at first longer than the body because the muscles and limbs do not develop until they are stimulated by the spinal nerved. So the spine must grow and mature enough that it can send out the proper signals for muscles, limbs, and internal organs to begin their growth. For this reason, the spine at first is bigger than the limbs, but later the arms and legs become largest. It is therfore not a useless "vestigial tail".
Since all animals with hands and feet have those during development, why would it be vestigial? Hox genes (unique to each animal) control the breakdown of these structures by inducing apoptosis.

You survive without a stomach as well...
Why not? Should we go through the exercise of why the stomach is vestigial as well?

My apologies, i was referring to New world monkeys.
An article i pasted as reference earlier if you read carefully.
Even though it is a separate structure. Guess the appendix is as much associated with the cecum as the small intestine is.

Exactly how does evolution explain male mammal nipples? According to evolutionary theory, the male/female differentiation evolved much earlier than mammals are supposed to have evolved from reptiles. That is, there were allegedly already males and females long before females evolved breast-feeding. Incidently, male nipples have a function during development. Mammalian embryos contain characteristics of both sexes at first, because they all have basically the same genetic information, and this information is expressed as efficiently as possible as the embryo develops. For example, in all human embryos, at first both the müllerian duct system (female) and the wolffian duct system (male) develop, because both sexes have the genetic information for these structures (a features creationists term "design economy" and "efficient embryological development"). The subsequent differences are the result of designed chemical signals that control the expression of the information. E.g., a gene set usually found on the Y chromosome controls the levels of testosterone and dihydroxytestosterone (DHT) secretion. Above a certain level, these hormones suppress the development of the müllerian duct system and promote the wolffian duct system, so the embryo takes on masculine characteristics. Below a certain hormone level, the opposite happens, and the embryo takes on female characteristics. Male nipples respond to these higher levels of androgens. Nipples aren't evidence for evolution (how does evolution explain it?) and not evidence against creation.

According to evolution theory, human hair is useless and humans won't have hair in a few generations as it is vestigial and useless.
However:
Human body hair, which covers almost the entire body, has a functional advantage over other mammal hair in that it has a high degree of touch perception, which occurs when a hair is moved or bent.
Hair on top of your head covers the spot where about 40% of heat dissipates. Fine body hair also plays an important role by extending the boundary layer, preventing excessive skin loss.
When you perspire, or sweat, the hairs grasp the sweat and keep it near you. This will keep your body cooled.

There is no consensus on what the atmosphere was like 3 billion years ago. Some say oxidized form, some say reduced form. DNA does not replicate by itself... You are right, it does replicate itself through a very complex mechanism that does need RNA, DNA, proteins and a temperature and pH regulated environment.

Ah, the RNA world hypothesis, very interesting. The best hypothesis so far but with enormous, near impossible, hurdles to overcome. Do hope they come to a conclusion sooner rather than later.

Changing of pre-existing genetic information? Mendelian genetics?
Life must be there to survive such conditions. Which conditions are you referring to?

My thoughts on the origins of life:
Science tries to explain origin of life in a naturalistic manner, but can't at the moment (abiogenesis), although it is believed that the fossil record points out that it is a given, which is not scientific.
Creationism explains life as the result of purposeful design created by a creator. Non-naturalistic, although as indirect evidence they will point to the genetics as a code and that all codes requires a creator, as well as as irreducible complexity. Some creationists believe that the fossil record also prove creationism, and that it is just a matter of interpreting the evidence in the "correct" manner.
Both belong to the realms of philosophy at the moment in my opinion.

For the moment i like science.

This could continue on for ever like this. So we should agree to disagree are that is all we are likely to agree on in relation to this matter and if I continue, I continue to use this as a good excuse not to work.

Or we can both agree on facts if you want. Feel free to point out were i was factually incorrect.

I will contend the following as "fact":

The modern synthesis of Neo-Darwinism says that: natural selection and random mutation = evolution from single-celled organisms to man. Natural selection plays a part in "choosing" the fittest randomly. However mutation only leads to degradation of intracellular systems, and i cannot see how single-celled organisms "degraded" into the complexity of life we see today, no matter how long it takes.

2) The level of complexity in organisms have to be present before evolution/adaptation can take place. There is no mechanism (currently) how DNA molecules can assemble through natural processes. Believing it can (atm) is pure faith.

3) Recapitulation is a myth.

4) Most, if not all of the icons of vestigiality is myth. (How about a thread to discuss this?)

BIG CHANCE TO WIN $250,000 AND PROVE THERE IS NO GOD!!!!!!!!!!!!!!

I have a standing offer of $250,000 to anyone who can give any empirical evidence (scientific proof) for evolution.* My $250,000 offer demonstrates that the hypothesis of evolution is nothing more than a religious belief.

Observed phenomena:

Most thinking people will agree that..

A highly ordered universe exists.
At least one planet in this complex universe contains an amazing variety of life forms.
Man appears to be the most advanced form of life on this planet.
Known options:

Choices of how the observed phenomena came into being..

The universe was created by God.
The universe always existed.
The universe came into being by itself by purely natural processes (known as evolution) so that no appeal to the supernatural is needed.
Evolution has been acclaimed as being the only process capable of causing the observed phenomena.

Evolution is presented in our public school textbooks as a process that:

Brought time, space, and matter into existence from nothing.
Organized that matter into the galaxies, stars, and at least nine planets around the sun. (This process is often referred to as cosmic evolution.)
Created the life that exists on at least one of those planets from nonliving matter (chemical evolution).
Caused the living creatures to be capable of and interested in reproducing themselves.
Caused that first life form to spontaneously diversify into different forms of living things, such as the plants and animals on the earth today (biological evolution).
People believe in evolution; they do not know that it is true. While beliefs are certainly fine to have, it is not fair to force on the students in our public school system the teaching of one belief, at taxpayers’ expense. It is my contention that evolutionism is a religious worldview that is not supported by science, Scripture, popular opinion, or common sense. The exclusive teaching of this dangerous, mind-altering philosophy in tax-supported schools, parks, museums, etc., is also a clear violation of the First Amendment.

How to collect the $250,000:

Prove beyond reasonable doubt that the process of evolution (option 3 above, under "known options") is the only possible way the observed phenomena could have come into existence. Only empirical evidence is acceptable. Persons wishing to collect the $250,000 may submit their evidence in writing or schedule time for a public presentation. A committee of trained scientists will provide peer review of the evidence offered and, to the best of their ability, will be fair and honest in their evaluation and judgment as to the validity of the evidence presented.

If you are convinced that evolution is an indisputable fact, may I suggest that you offer $250,000 for any empirical or historical evidence against the general theory of evolution. This might include the following:

The earth is not billions of years old (thus destroying the possibility of evolution having happened as it is being taught).
No animal has ever been observed changing into any fundamentally different kind of animal.
No one has ever observed life spontaneously arising from nonliving matter.
Matter cannot make itself out of nothing.
My suggestion:

Proponents of the theory of evolution would do well to admit that they believe in evolution, but they do not know that it happened the way they teach. They should call evolution their "faith" or "religion," and stop including it in books of science. Give up faith in the silly religion of evolutionism, and trust the God of the Bible (who is the Creator of this universe and will be your Judge, and mine, one day soon) to forgive you and to save you from the coming judgment on man’s sin.

*NOTE:

When I use the word evolution, I am not referring to the minor variations found in all of the various life forms (microevolution). I am referring to the general theory of evolution which believes these five major events took place without God:

Time, space, and matter came into existence by themselves.
Planets and stars formed from space dust.
Matter created life by itself.
Early life-forms learned to reproduce themselves.
Major changes occurred between these diverse life forms (i.e., fish changed to amphibians, amphibians changed to reptiles, and reptiles changed to birds or mammals).
Answers to Commonly Asked Questions about the $250,000 Offer

Students in tax-supported schools are being taught that evolution is a fact. We are convinced that evolution is a religion masquerading as science and should not be part of any science curriculum. It has nothing to do with the subject of science. There are at least six different and unrelated meanings to the word “evolution” as used in science textbooks.

Cosmic evolution- the origin of time, space and matter. Big Bang.
Chemical evolution- the origin of higher elements from hydrogen.
Stellar and planetary evolution- Origin of stars and planets.
Organic evolution- Origin of life from inanimate matter.
Macroevolution- Origin of major kinds.
Microevolution Variations within kinds- Only this one has been observed, the first five are religious. They are believed, by faith, even though there is no empirical evidence to prove them in any way. While I admire the great faith of the evolutionists who accept the first five I object to having this religious propaganda included in with legitimate science at taxpayer’s expense.
Even a quick review of a typical public school textbook will show that students are being deceived into thinking all six types of evolution above have been proven because evidence is given for minor variations called micro-evolution. The first five are smuggled in when no one is watching.

This deception is a classic case of bait and switch. One definition of evolution (such as “descent with modification”) is given and the others are assumed to be true by association. The first five meanings are believed by faith, have never been observed and are religious. Only the last one is scientific. It is also what the Bible predicted would happen. The animals and plants would bring forth “after their kind” in Genesis 1.

Many have responded to my offer of $250,000 for scientific proof for evolution. The terms and conditions of the offer are detailed very clearly on my web site www.drdino.com. Here are some answers to some commonly asked questions.

The offer is legitimate. A wealthy friend of mine has the money in the bank. If the conditions of the offer are met, the money will be paid out immediately. My word is good.
The members of the committee of scientists that will judge the evidence are all highly trained, have advanced degrees in science as well as many years of experience in their field. For example: there is a zoologist, a geologist, an aerospace engineer, a professor of radiology and biophysics, and an expert in radio metric dating to name a few. They are busy people and do not wish to waste time on foolish responses. Nor do they wish to waste time arguing with skeptics and scoffers who seem to have nothing else to do than ask silly questions when they really don’t want answers (so far this has been the typical response to the offer). I will not reveal their names for this reason. Any legitimate evidence will be forward to them and they will respond. At that time they may identify themselves if they choose. The merit of the evidence presented and the reasonableness of their response does not depend on who they are.
Evidence of minor changes within the same kind of plant or animal does not qualify as evidence and will not be sent to the committee to waste their time. For example, doubling the chromosome number of a sterile hybrid does not add additional genetic information; it duplicates what is already present in the parent plant. Because of the absence of additional genetic information the resultant plant can't be classified as different or new species. The plant may differ in a number of ways - bigger, vigorous as observed in any polyploid plants. Such easily recognizable phenotypic changes have confused many. Some evolutionists have jumped to the conclusion that a new species has been evolved. The key is that no new genetic information has been added. Even a new “species” is not proof for evolution as the offer calls for. See the conditions of the $250,000 offer on the web site. Some have insisted on a precise definition of the word “kind”. The Bible defines “kind” as those that are able to “bring forth” or reproduce. Those animals that were originally able to reproduce were of the same kind. There may be diversity now, 6000 years later, that could cause some varieties of the original kind to not be able to reproduce now. For example, I understand that rabbits from Alaska cannot breed with rabbits from Florida yet they are still the same kind of animal. It is obvious that a dog and a wolf are the same “kind” of animal (they are currently classed as different “species” yet are inter-fertile-- hmmm, what is the precise definition of “species”?) where a dog and a fish are not. While there may be some blurry areas that would be worthy of research in defining the original kinds, rather than muddy the issue with these type questions it would be wise to focus on the obvious cases like the dog/fish comparison. These are obviously different “kinds” of animals. So, for the sake of clarity, prove the dog and the fish evolved from a common ancestor. The honest scientist would be wise to admit that no evidence exists that could begin to prove the dog and the fish have a common ancestor. He may believe that they are related but that is not science and that is my point in the offer. Some believe this type of evolution happens but it should not be presented to innocent students as a “fact”. Further, it certainly is not evidence that the other four definitions of evolution have occurred.
The idea that the majority of scientists believe in the theory is not evidence either. Majority opinion is often wrong and must be corrected. History is full of examples.
Anonymous letters will be ignored.
Rather than simply sending in scientific evidence for evolution, some have wasted lots of their time and mine sending letters demanding to know who is on the committee, what bank account the money is in, asking Bill Clinton type questions about the definition of words like “is”, etc. When I do not respond the way they want me to they post notices on their web sites claiming that I owe them the money or that the offer is a sham! It is obvious they are using the Red Herring tactic to draw attention away from the fact that they have no evidence to support the religion of evolution. I tell everyone who inquires, if you have some evidence, send it in, don’t beat around the bush. Give us the best you have on the first try please to save time.

Many have offered evidence of microevolution and assumed that the other 5 meanings of the word are somehow magically connected. They don’t seem to realize that they are blinded to the obvious. Treat the $250,000 offer as a lawyer would treat a ‘who-done-it’ case. It is your job to prove that what is being taught to our kids as fact (all six meanings of the word evolution above), is indeed a fact. If this cannot be done then it should be admitted that evolution is a religion but not a science. Some say it is unfair to define evolution including the origin of the universe. They say it only has to do with “change in gene frequency over time.” All you need to do is read your local textbook and see that all 6 meanings of the word are part of what is taught as evolution theory. If these nay Sayers are agreeing that it should not be included then they should help me get it out of the books, if they are genuine.

Over the years I have heard many evolutionists say, “Evolution is a theory like gravity is a theory. Don’t you believe in gravity?” They repeat this mantra as if repetition will make it true. Their example is silly of course. We can all observe gravity every moment of our lives. We can do tests and experiments to verify the theory of gravity. No one has ever seen an exception to it. By the same token, no one has ever observed evolution nor been able to demonstrate any evolution beyond minor variations within the kind. To try to make evolution science by associating it with theories like gravity is ridiculous.

Nearly all responses to my $250,000 offer go something like this: “Of course no one can prove evolution, can you prove creation?” This response is what I expected and wanted. Neither theory of origins can be proven. Both involve a great deal of faith in the unseen. So my next logical question is: “Why do I have to pay for the evolution religion to be taught to all the students in the tax supported school system?” Since all taxpayers are being forced to pay for evolution to be taught exclusively in public schools and evolutionists have had the last 130 years and billions of dollars in research grants to prove their religion, the burden of proof is on them to supply proof of their theory.

I do not have time or interest in getting involved in long e-mail debates, but I will talk to anyone by phone or debate with any qualified scientist (even a panel of evolutionists) in a public forum at a university, on radio or TV, as long as there is equal time for each position not each person. If you call, please have a list of topics to discuss or questions to ask and feel free to record the conversation if you like. Just inform me that you are recording please. I hope this response is satisfactory.

I have taught for years that evolution is nothing but a religion mixed in with real science. Many have been duped into believing in it. There is no evidence that any plant or animal ever can or did change to any other kind or creature. It is time that intelligent people the world over began to admit that the king has no clothes! There is no evidence for changes between kinds of animals. The Bible teaches that God made them to “bring forth after their kind.” This is all that has ever been observed. The same Bible teaches that everyone will face the Creator one day to be judged for everything they have said, done or thought. I recommend that everyone prepare for that day by taking advantage of God’s mercy and forgiveness afforded through the free salvation offered to any who will confess their sin and receive Jesus Christ as their Lord. If you are interested in learning more about becoming a Christian, please call me. I travel a lot but always take time for calls when I am in the office. I am most often in Wednesday through Friday at 850-479-3466. Check my itinerary on my web site for my location if you need to talk with me while I am out speaking. If possible, attend a seminar. Seminars are free and we always have a question answer time for those who attend.

Sincerely,
Kent Hovind

I believe GOD created evolution and set the World up to be a crap shoot, there is evidence for the World being a crap shoot in the New Testament from the direct quotations of JESUS which are in red in my King James Bible. JESUS was asked who sinned if a house fell down and killed the people inside, the answer JESUS gave was that no one sinned. This means that sh** happens and the World is a crap shoot if you are in the wrong place at the wrong time bad things can happen to you through no fault of you own. GOD gave free will which means he does not interfere in the World unless it changes the outcome that he has set up. And if you think the World is only 6000 years old, this does not come from the Bible the Bible gives no age of the Earth the 6000 years old idea came from the writings of a Catholic Monk in the Middle Ages. You might find that you have more understanding of the Bible if you get what I have which is program that takes the King James Bible words of the Old Testament and shows you what the original Hebrew worlds were that were translated and shows the Hebrew dictionary meaning or meanings of the words. There is evidence in Genesis for evolution using the Hebrew dictionary meaning of the words "Let the earth bring forth" and "And the Spirit of God moved upon the face of the waters" which is real bad translation because in the Hebrew dictionary it is more like a hen sitting on eggs waiting for them to hatch. I also am a Christian but GOD can do anything so there is no reason to say that he did not create evolution.

Sorry, no offence is meant by my abresiveness, it is just stress (well with some people). I'm also dyslexic and it seems a waste of time to worry about unsing a spell check on an internet forum (and there are far worse spellers than myself).

1) I disagree on the grounds that it is possible to have mutation that does not degrade, it is however improbable. However not improbable enough to have never happenend as you can assume that can not have happenend once. It is not the only method that could have led to change either.

2) There is no known method, however there is evidence enough to suggest it did happen and hence it is not just faith.

3) In its original idea yes, however the original theory has altered from it 19th century version

4) Some some are not so, and some are debatable.

I can do the stegosaur and cryptozoological arguements with out looking information up or at least not much. With you I can not however. But you put together a well thought out arguement which makes a nice change. I really do have a deadline to meet though sad.gif I have to decline the invitation however for the thread unless of course you want to debate otters.

I'm not sure why exactly you two are debating Recapitulation.

QUOTE
Modern biology rejects the literal and universal form of Haeckel's theory. Although humans share ancestors with many other taxa (roughly, fish through reptiles to mammals), stages of human embryonic development are not functionally equivalent to the adults of these shared common ancestors. In other words, no cleanly defined and functional "fish", "reptile" and "mammal" stages of human embryonal development can be discerned. Moreover, development is nonlinear. For example, during kidney development, at one given time, the anterior region of the kidney is less developed (nephridium) than the posterior region (nephron).

The fact that contemporary biologists reject the literal or universal form of recapitulation theory has sometimes been used as an argument against evolution by some creationists. The argument is: "Haeckel's hypothesis was presented as supporting evidence for evolution, Haeckel's theory is wrong, therefore evolution has less support". This argument is not only an oversimplification but misleading because modern biology does recognize numerous connections between ontogeny and phylogeny, explains them using evolutionary theory without recourse to Haeckel's specific views, and considers them as supporting evidence for that theory.

Unfortunately, some older editions of textbooks in the United States still erroneously cite recapitulation theory or the Haeckel drawings as evidence in support of evolution without appropriately explaining them as being misleading or outdated. Because the actual scientific theory is difficult to explain in layman's terms, expressions of doubt about evolution that point to the flaws in Haeckel's arguments typically go unchallenged in popular media.


Here's another quote from the same article about some of the modern observations.

QUOTE
Generally, if a structure pre-dates another structure in evolutionary terms, then it also appears earlier than the other in the embryo. Species which have an evolutionary relationship typically share the early stages of embryonal development and differ in later stages. Examples include:

The backbone, the common structure among all vertebrates such as fish, reptiles and mammals, appears as one of the earliest structures laid out in all vertebrate embryos.

The cerebrum in humans, the most sophisticated part of the brain, develops last.

If a structure vanished in an evolutionary sequence, then one can often observe a corresponding structure appearing at one stage during embryonic development, only to disappear or become modified in a later stage. Examples include:

Whales, which have evolved from land mammals, don't have legs, but tiny remnant leg bones lie buried deep in their bodies. During embryonal development, leg extremities first occur, then recede. Similarly, whale embryos (like all mammalian embryos) have hair at one stage, but lose most of it later.

The common ancestor of humans and monkeys had a tail, and human embryos also have a tail at one point; it later recedes to form the coccyx.

The swim bladder in fish presumably evolved from a sac connected to the gut, allowing the fish to gulp air. In most modern fish, this connection to the gut has disappeared. In the embryonal development of these fish, the swim bladder originates as an outpocketing of the gut, and is later disconnected from the gut.
