Uh-huh, and God gave us a tailbone that looks an awful lot like the ones our ape relatives have just for the purpose of shitting.


Yeah, and you skin looks and feels an awful lot like pig's, so which one of your relatives is a pig?


My great-great-great (however many greats you need to go back a few million years) grandpa. Our skin performs the same function as a pig's skin, so it makes sense that a deity would have given both similar skin. What doesn't make sense is that a deity would have given humans and apes a similar, but slightly different, bone that serves an entirely different purpose in each.


What's to say that the actions of God should make sense to you or any of us?

Well, if he made us in his image, I guess He does.

If evolution is so great in predicting things of the past and fossils provide a record of events, how come there are no gradual changes in bones found?
Quote

Because the occurance of naturally occuring fossils compared to the number of larger organisms that have lived is so statistically small that is unlikely to find any direct chain.


And if The world was created 10,000 years ago with Adam and Eve, why were there native americans in eastern PA 10,000 years ago?  That's one heck of a walk (and swim, the Artic land bridge was from 13,000 to 40,000 years ago).

They believe the Earth is 6000 years old, not 10,000, and probably believe that the dating of such early North American artifacts is fallacious, despite the fact that if such dating methods were nearly so fallacious as they claim (i.e., rates of radioactive decay were so much faster in the past that all the decay we see now happened in only 6000 years), the Earth would be a radioactive, unliveable cinder.

Quote from: "troubadour"

-In Leviticus among many laws there is one that instructs to wash your hands after you take a dump or handle something dead. In the same 18-century, after the discovery of microorganisms, all hospitals implemented mandatory rule about washing hands before any procedures. Again how would people who "faked" the bible know about microorganisms?


Was not Moses raised in Egypt?  Read up on the ancient Egyptians and their almost obsesive cleanliness.  They went so far as to shave their bodies and heads to prevent lice.

To say that washing equates to a knowlege of germs, rather than an understanding of the benefits of washing, is just silly.  The Dark and Middle Ages had many examples of lost knowlege.  A person who could swim was considered evil and being rejected by the water, hundreds of years after Archimedies.  Washing was looked on as bad, and was thought to cause disease.  That one follows through to the modern age, how many times have you been told not to go out with a wet head, or you will get sick?

I could as easily claim the the ancients knew of DNA, look at the caduceus.  Two snakes coiled around each other in a double helix, used a symbol of healing, the Staff of Asclepius is also related to medicine and is a single helix (RNA?).  A study of ancient cultures does indicate that they knew much about health that had been lost (the lost knowlege is why the Dark ages are called that).  

The Renaissance was a "Rebirth", a rediscovery of what had been lost.

The supernatural can, of course explain anything- but homologous and vestigial structures are better explained by common descent.


You think so? I already told you the function of coccyx in your body, and I think it is very important one. BTW animals, like apes, have a vertebra that has the same function as coccyx in human body. The only difference is that apes have more vertebrae after coccyx which form a tail that has different function than coccyx. And the fact that the functions are the same can be explained by a common design.

Are there any other structures in your body that you think you don't need?

I'm a man, and I have nipples, and an appendix, and hair on my body, and ear lobes, and had to have my wisdom teeth removed because my jaw was not big enough to accommodate them.  

Just a few quick examples of gross anatomical relics.

I try to give the benefit of the doubt and go with the long estimate, since at 6,000 years there is the question of several ancient cultures that predate.

Yes, something like that. He also made us dependent on natural resources, food, water, air, and many other things that we came to enjoy.

And don't forget that we were made in the image of God, so it is also possible that during creation God was recreating His own body in all the details.

He also made them Male and Female,

So why do they become both:

[quote'"http://news.yahoo.com/s/ap/20060906/ap_on_sc/intersex_fish"]The worrisome fish were first found in a West Virginia stream in 2003. Now, scientists are finding male smallmouth and largemouth bass with immature eggs in their sex organs at testing sites dotting the region.

Last month's testing at three tributaries emptying into the Potomac revealed that more than 80 percent of all male smallmouth bass found were growing eggs, according to Vicki S. Blazer, a fish pathologist with the        U.S. Geological Survey.

At a testing site in Washington, seven of 13 male largemouth bass showed some kind of unusual feminine characteristic, Blazer told The Washington Post. Six of the seven tested positive for a protein used to produce eggs and three actually carried eggs.


Either the males carried the female genes as evolution would support, or a few chemicals modify the genetics of a creature adding features that would not normally express.  Now if that sort of thing would continue for generations who knows what would happen...I wish I could think of a word to describe it..A word that would describe a change in a creatures genetics, producing something slightly different from it's parent.

Dude! That is not at all what I believe.



So, what do you believe?


Quote

I meant macroevolution as speciation, not common descent. THERE. ARE. NO. KINDS. They do not exist. They are fiction. No one has ever demonstrated what a "kind" is or what blocks evolution from occuring at that level. Lots of small changes =  big change, and no one has ever shown what prevents lots of small change from accumulating into big enough change to break the "kinds" barrier, nor for that matter has anyone shown where the "kinds" barrier is.


Of course they kinds exist. You have to stop thinking in terms of evolution. Two animals are the same kind if they can produce offspring.


Quote

Now, please address the points in my last post. If evolution cannot create information, how is that any given species expresses far more genetic variation than could possibly have been contained in only two representatives?


Dogs have 78 chromosomes with average 100K genes on each strand. That’s 7.8 million genes. So, how many unique combinations of genes can 2 dogs produce? Total of 15.6 mil genes we are selecting 7.8 mil

15,600,000!/(7,800,000!(15,600,000-7,800,000)!) = X dogs with unique DNA from just 2 dogs, where X is around 51 billions if not more. (I approximated the answer because numbers were too large to be calculated in Excel)

So I think you have enough DNA material to populate Earth from 2 representatives.

Quote

If the geographic strata are caused by "hydraulic sorting" how is it that many light animals, including a number of flying creatures, are closer to the bottom, and many heavy animals are on top?


Hydraulic sorting is not a precise process, some deviation from average result will occur, besides don't forget that it was a storm that shook everything pretty heavily, and produced currents that could have deposited lighter animals deeper and visa versa.


Quote

If evolution can work within "kinds" but not beyond them, and humans and apes are totally separate "kinds", how is it that the genetic difference between humans and chimpanzees is smaller than the genetic difference between a number of animals that are supposedly in the same "kind"?


Well, that is simply not true. Apes have 24 pares humans have 23 pairs, so already you have 2 chromosome less than a chimp, so no matter how much of a difference you'll have within those 23 pairs, chimps will still have one more pair. Now it is true that DNA of a human is about 95% similar to a chimp's DNA, but so what? Power point' code and Excel's code is about 90% similar too, does that mean both of those progs evolved from a Morse code? NO! It just means they had the same programmer. Same as Humans and chimps have the same creator.

Your nipples, shockingly, can produce milk after a month of stimulation, don't believe me - review some medical literature.

Hair on your body is important for thermoregulation of your body.

Appendix is a home for a special kind of bacteria that help you in digestion, well, in actuality, bacteria digests the food and than you digest and reabsorb the bacteria.

According to Bible pre-flood people were bigger that we are now and had a lifespan of 300-400 years. Bigger people means bigger jaws, longer lifespan means wisdom teeth will grow later in life, say at 20-40 years old.

And what's wrong with ear lobes? It is the bottom part of your ear arch, you think you don't need it?

You asked what parts don't I need. Not what part do not have purpose.

biblically it is the woman's job to care for the baby, why should a man have the equipment?

Where is the fossil evidence of longer lived or larger people?  All of the early man fossils I've seen are smaller, but with larger jaws.  Smaller peolpe with bigger jaws..Kind of goes against your statement.  Also Bigger poeple, bigger teeth bigger jaws, if proportional there is no reason for wisdom teeth problems.  And even if your conjecture that earlier people developed later were true, it would still tend to be proportional.

By the way, I was 35 when I had my wisdom teeth removed, well within your "20 to 40" year range.

The amount of disgestion that occurs in the appendix of a human is minimal, A pig on the othe hand has a fully developed one.

oops forgot...earlobes, need them? Nope, just a flap of skin below the cartilage.  No purpose.
And finally, Why does the bible go into so deep of a detail about Joseph's linage when it tells us that Jesus was not his son? (and therefore not of the house of David).

You use a much smaller definition of "kinds", then, than most Creationists. Two animals that can produce offspring (specifically, offspring that can themselves produce offspring) is not a "kind", it's a species. And evolution of new species from a single population has been observed many times, both in the laboratory and in the wild (see http://talkorigins.org/faqs/faq-speciation.html). If that's your definition of "kind", then evolution certainly can produce new ones! Other Creationists, however, use wildly varying definitions of "kinds". If "kinds" are so distinct, and there's no gray area in between, why can't Creationists agree on what they are?

Your calculations are far, FAR too simplistic. We're not talking about unique combinations of genes, but specific genes. For instance, the eight humans on the ark could have carried at most 16 alleles for every genetic locus, but the total number of unique alleles for some loci in the human species can be several hundred (some of the HLA genes, for example, have over 400 alleles in the human genome)! This means brand-spanking new genes.

The geographic strata absolutely could not have been laid down by a flood. If an imprecise process created the layers we see today, we would expect to see at least a few trilobites in the Cenozoic and hominids in the Paleozoic! Yet species appear in the strata, last, then disappear- they occupy a certain number of layers and are found nowhere else.

Biologists don't simply look at the average genetic similarities, they look for which genes are shared between species. For instance, it was long predicted from genetics that whales had evolved from land-dwelling mammals, but no transitionals had yet been found. A testable prediction of this hypothesis was that transitionals should demonstrate how the cetacean ear evolved from an ear suited to the land to an ear suited to the water. And guess what? They found transitionals that showed exactly that. Early whale ancestors, the pakicetids, had the same type of ear as land mammals. Then, the protocetids, which came about five million years later,  still had the land-suited sound transmission system, but had a primitive version of the system found in modern whales as well! And over the next few transitional whales, the land-suited system disappears and the sea-suited system further develops. Prediction resoundingly confirmed. There are literally hundreds of evolutionary predictions just like this.

This is completely false.  In fact there are plenty of examples of gradual changes.  The best example is with humans - there is a great example of evolution from our ancestors to our current form - especially in human skulls.  Anti-evolutionary people often get confused because scientists, for simplicity sake, drew lines as what's classified as homo sapian sapian and what is classified as homo sapian erectus (and the other levels of evolution prior to this) however a quick glance at the skulls of early homo sapian sapians shows a clear progression consistant with carbon dating showing a gradual change in the bones to be what we are today.

Erlier, I outlined 3 conditions for fossils to become evidence (gradual change traced over millions of fossils, strict cronological order of fossils, and direct descend, meaning yonger bones are direct offspring of older bones), if this research complies with those conditions, I'll look at it, if not, why bother? You can't make conclusions about land animal turning into whale based on a ears of half dosen bones.

There are. Evolutionists work with a preconception that humans did not exists before dinos, so whenever human fossils are found they get dismissed as burial grounds of some tribe. There was one site (I think it is a national park somewhere in mid USA) where human tracks were found with dino's tracks, but since it does not sit well with the theory, it got dismissed. The explanation was that there existed a dinosaur with human-like feet.

What I mean is, why are there no human fossils found in the lower strata? If all the fossils were placed there at once, you would think that there would be some human fossils mixed in the lower areas. But human remains are only found near the top.

There were many supposed sights, but after the tracks were more closely scrutinized they were found to be decidedly not human (some were even fake).

No! Where did I mention rocks?? It has been demonstrated how many of the basic parts of living organisms could have assembled themselves on the early Earth, requiring nothing more than the conditions that we already know existed (a reducing, low-oxygen atmosphere, lots of organic molecules, heat, etc.). Stanley Miller and Harold Urey showed that amino acids could assemble themselves, given these conditions; Sidney Fox showed that amino acids could assemble themselves into polypeptides, which are essentially simple proteins, and that these could assemble themselves into reproducing "microspheres". Other research has shown that even very short strands of RNA can copy themselves. There are gaps, but absolutely no need for divine intervention.

So you keep saying, but "cats" are not a distinct clade. The lines between taxa are actually quite blurry. Saying a cat will never produce a non cat is like saying that continually adding 0.001 to 1 will never produce 2. And additionally, humans are more closely related to chimpanzees than some types of cats are to some other cats- yet humans and chimps are different "kinds".

No. There are zero anomalies. It would be far too great a coincidence to suppose that all fossils just 'happened' to fall into a group of layers and appear nowhere else.

Don't you know the story that is in all the textbooks. "First Earth was full of molten lava, then lava cooled down and rain filled the oceans, where life began as a simple single cell organism" So, you do come from a rock if you believe in evolution.

Here are a couple of points on Miller-Urey Experiment, assuming you know the process and apparatus they used:
-methane and ammonia concentrations were selected for the sole purpose of trying to create organic molecules.
-methane-ammonia atmosphere would prevent life rather than create it. It would actually destroy any organic molecules the moment they formed, if it were even possible for them to form.
-ultraviolet light would destroy ammonia more quickly than it could form.
-amino acids which have been formed in an electric discharge, have rapidly moved from the site of their formation and accumulated in an adjoining vessel, if they weren't they would have been destroyed even faster than they were formed.
-substances formed in the atmosphere could not so rapidly leave the realm of their formation because for something this small it takes three years to move from the stratosphere to the surface.
- they produced barely 2 amino acids out of 22 needed for life and even the ones they produced were R-form amino acids, whereas for life to exist you need L-form acids as well as D-form sugars, which no one has been able to produce.

And another big point. Even if you can create life in the lab it would prove that you need intelligence and sophisticated technology to create life, and not a couple of goo drops on a rock and a lightning.

All the amino acids necessary for life have been produced in subsequent experiments- as well as all the DNA and RNA bases- and many of them in fact exist in space, so we can be absolutely confident all the amino acids and all the bases would have been present no matter what the atmosphere was like. Further experiments simulated wildly varying atmospheric conditions and stil produced complex organic molecules.

A reducing atmosphere would indeed destroy most modern forms of life, but many simple modern organisms DO survive in reducing environments. That the early Earth's atmosphere was a reducing one relatively similar to that simulated in the Urey-Miller experiment, within a broad range, is supported by geological evidence.

What are your sources for such statements?

Oh yes, and if it is true about amino acids produced in the lab, it doesn't mean it can spontaniously happen in the wild.

Reducing nature of early atmosphere: http://news-info.wustl.edu/news/page/normal/5513.html

Either way it doesn't much matter, many of the amino acids necessary for life have been found in space, for crying out loud (one meteorite contained over 90 million amino acids, including nineteen of those used in modern organisms- source: http://chemport.cas.org/cgi-bin/sdcgi?APP=ftslink&action=reflink&origin=npg&version=1.0&coi=1:CAS:528:DyaE3MXisVCnsg%3D%3D&pissn=0028-0836&pyear=1983&md5=cb8b015f54156458fa2be8cdca44789f), so we can be certain beyond doubt that all the amino acids would have been present. Further, your statement that only 2 amino acids were formed, and that life needs both left-handed and right-handed amino acids, is completely false. The experiment formed thirteen of the twenty-one amino acids necessary for life, and produced left- and right-handed acids in roughly equal quantities; most living organisms, however, use only left-handed amino acids (source: http://www.science.siu.edu/microbiology/micr425/425Notes/14-OriginLife.html, scroll down to "the Miller Experiment"). Additionally, examination of the genes that are considered "oldest" shows that the amino acids formed by the experiment are the most common in those genes (source: http://mbe.oupjournals.org/cgi/content/full/19/10/1645).

Since amino acids exist in space, the point is moot. But the experiments try as well as a possible to mimic conditions on the early Earth. Further, the Urey and Miller obtained their results in only one week; imagine what could happen in a few hundred million years!

So you believe that you come from a rock from outer space.

I already explained to you why Urey-Miller Experiment is irrelavant. And you keep repeating your millions of years thing, I don't believe Earth is milions of years old, so those arguments don't work on me.

And I just explained why it is very relevant, because all the points you raised were wrong.

Considering alot of our history in that time period comes from the Bible, I hope you don't mean to say that its entirely fictional.

A few things...

Quote from: "googleSearch"
Are there any other structures in your body that you think you don't need?

Once again explain WHY men have nipples, why humans have appendices, hair (nope, not needed for thermoregulation, or else there wouldn't be perfectly healthy 98.7 degree people walking around totally hairless), uvulas, wisdom teeth and tonsils. Head hair I'll let you have, I'm referring to body hair.

This actually ties into your claim that creationism can explain anything that evolution can. Evolution has explanations for those things, now I want to hear  creationism's.

Oh, and is there also an explanation for dating methods that perfectly align with the predicted chronology of the evolution of life on Earth?

Also, one of the explanations for the Jews surviving that final plague God sent down was their obsessive practice of food storage; they recognized that leaving it out attracted rats, and that there was some connection between rats and sickness. Recognition of a connection is not evidence of knowledge of microbiology. If they did have that kind of knowledge, it wouldn't have been difficult for them to have taken some moldy bread and developed a primitive form of penicillin.

One last thing, do you truly understand the Theory of Evolution by means of Natural Selection? Because I don't think you do.

You should read up on Darwin's Finches. If evolution wasn't possible, then we wouldn't see the wide variety of dogs we see, and if animals have some "program" (for lack of a better word, not to be taken and misconstrued for some retarded "God putting a computer together" analogy) that can allow that much change, then what's to prevent it from changing even more, possibly into something considered to be a new species, given millions of years (into the future from now, not the age of Earth, which is a wholly different point you're mistaken about)?

Hair is needed for thermoregulation, look it up in any anatomy book. Don't forget that we were created to live in Eden and be naked all the time, so body hair plays important role in thermoregulation. And I bet whose perfectly healthy 98.7 degree people don't walk around naked, do they? Uvula plays important role in articulation of the sound of the human voice to form the sounds of speech. Tonsils catch incoming germs, which cause infections. As of the rest - I already explained earlier in the thread.

Look, why don't you take an anatomy book and read up on specific functions of parts of your body. If you think you don't need those parts, go ahead and remove them, for all I care, and while you are at it you can also remove you arms and legs, because you can survive without them. Because that’s what you people think, if you can survive without it - it's vestigial.

Microevolution happens, it is observable, I got no problem with that one, it is the "one fish turning to a dog" I have a problem with.
First, all those variety of dogs already had all the genes for looking different from each other. So it is a simple job of turning those genes you need on or off. So there is a bound of what you can get from breeding dog to a dog - you get a dog. If there were no bound than KFS would be growing 7ft. chickens with 6 legs and 4 wings by now.
And second, you people keep feeding me with this millions of years stuff, I'm a young Earth creationist, I don't buy you millions of years.
