* I am a devout Christian who believes the Bible to be 100% accurate
Well, let me ask you this, and this is an important question. Are you willing to consider that your belief may be wrong? That is, that the bible ISN'T 100% correct?
Because if you cannot be swayed from this possition, there is not point in a discussion.
* I believe in micro- but not macro- evolution
No such thing. What creationists call 'micro' and 'macro' are the same thing. Biologists make no such distinction.
* I am interested in recieving information which might serve to either prove or disprove evolution on the topic being presented.
Nothing can be proven 100%, but a hypothesis can be ruled out on the basis of evidence. Currently the evidence points toward evolution and fully contradicts creationism.
...but come on people!! Present at least a few decent facts or links to factual, studied evidence before pouring out your heart into an area you haven't even taken to research for yourself...
Are you refering to evolution? I see studies posted here every day. Many of our posters are actual scientists in the field. What are you talking about?
... If, as "assumed" by evolutionary scientists, the world is some billion years old and we, as non-designated species are in constant transition, with projected THOUSANDS of stages within our develpement, with a fossil record beyond belief to "supposedly" support such and ideal, are we unable, or incapable of presenting ANY SIGNIFICANT finds which would SCIENTIFICALLY prove that belief?
There are plenty of finds and there is plenty of evidence. What would you propose we find in order to convince you? i.e. what is YOUR standard of evidence?
And even if we do have a few scraps, why, if we are in constant transition, including the staggering collection of fossils stated earlier, are there so few in contrast? Shouldn't there be THOUSANDS of such fossils, just, if not better preserved than their respective ancestors and decendants?
Again, it is important to this topic that you please explain what YOU think we should see in the fossil record, and what YOUR standard of evidence is.

Re: Do it yourself!
I like this idea
At another forum I visited, users could earn/lose special badges that would apear in the poster info. box. It would basicaly label an individual as "troll, poster of the month, etc.".
Another suggestion.

Re: Please watch your language
Is that reasonable? Unless you are predisposed to accept Pakicetus as a whale ancestor, it does not seem reasonable to me. Other creatures also have the same similar teeth pattern, which could just as easily have been created of convergently evolved that way. Same goes for the increased cranial cavity. It is thought to be a precursor to whale skulls, but hey, it could just as easily not be.
The evidence is so scant as to be farcical, but with a straight face such creatures are presented as transitional.
Ya know, back when we had that row in the whale transitional thread I pointed out to you that whales, and packicitids share the same order.
The following animals also share the same order:
The only reason packicetus bothers you so much is because you don't WANT it to be true. You don't LIKE the idea that he is a primative whale relative.
Though you gladly accept the same taxanomic principles that place bears, dogs, and seals in the order caniformia. I find it highly susppicious that taxonomy ONLY bothers you when it is applied to extinct species.

Re: Please watch your language
And I pointed out where one of the leading researchers in the field in terms of whale evolution states publicly that Pakicitids are in the same suborder and are "whales" or cetaceans.
Unfortunately, you are too obstinate to learn anything first time around, but here's the link. Note: Seals are not in this suborder.
I never said seals are in the same suborder as whales, I said they are in the same suborder as dogs and bears. That's caniformia.
And the fact that the researcher places packicitids in the same suborder as whales only bolsters my point.
SEALS AND DOGS ARE IN THE SAME SUBORDER. They look nothing alike, they live in entirely different environments, yet YOU HAVE NO PROBLEM WITH THIS FACT.
You sir, are incorrect! The same taxanomic methodology that puts dogs and seals in the same suborder is the same methodology that places whales and pakicitids in the same suborder.
YOU JUST DON'T LIKE THE IMPLICATIONS OF THAT.

Randman Dodging (as usual)
Yaro, it is totally inconsequential to this debate that evos classify dogs and sea lions in the same suborder or order. Why you think that opinion has relevance, I don't know, but evidently you think it has merit.
It has merit because your whole basis for not likeing the packicitus/whale connection is pretty much: "They don't look the same to ME, those well trained scientists with decades of research under their belt, are all wrong."
I'm basically asking you how does that argument hold up when sea lions and dogs are in the same order as well. Why don't you apply the same logi? "Seals, dogs, and bears don't look the same to me. All those scientists must be wrong."
Essentially Order is a pretty broad taxanomic classification. You have a big problem when it comes to whales and paki, but not dogs and seals. Makes your possition suspect.
[Just say no to blink please]YOU JUST DON"T LIKE THE IMPLICATIONS SO YOU REFUSE TO ACCEPT THE CONCLUSIONS.[/Just say no to blink please]
In terms of process, not man-made classifications, the relevant issue involves groups that can interbreed, which I will label species for this post (although current definitions of "species" can vary widely from that).
Yes, unfortunetly whales and pakis were never designated the same species. They are in the same order. So your insistence on bringing them up all the damn time renders your point moot. No one is suggesting they could interbreed.
Moreover, the whole nation that similarities automatically involves relatedness via common descent is just a large, and totally unproven assumption.
Then how do you explain all the similarities in mamals? And why as you go back do we see half/half breeds?
A good example are monotreems, classified as mamals, but in a lot of ways they are very reptilian. They are related to very primative mamals.
They lay eggs, are virtualy cold blooded, don't have nipples rather secreet milk thrugh their skin, they have a skeletal structure closser to lizards than to mammals. How do you explain those similarities?
Anser: you can't without invoking magic.
ABE: changed subtitle.

Re: Majority Accomodates Themselves
Logically, micro and macro makes sense. There needs to be some term for designating between intra-species adjustments and bonafide transitional evolutionary progress. Why doesn't micro/macro fit this ticket?
Because 'species' is a blurry line in the sand. I charactarize it as a spectrum, it's a smooth gradation form one organism to another. Species is a humanly imposed deffinition which as I sayd can be fuzzy at times.
In other words, there is no 100% absolutely clear line in the sand. And the smae proceses that make your kids look different from you are the same processes that make a dog look different from a cat.
So the terms really don't mean anything. There is just evolution nothing more.
As Ned and mike pointed out, the terms when used by creationists, are essentially straw men. A way of impossing a false delinitaion where there is none.

Point taken mark24, but again, I think creationsists want to co-opt the term to mean something it doesn't.

Re: Majority Accomodates Themselves
Whatever the label and whatever propaganda you guys want to spout, there is clearly no spectrum of life, but discrete groups separated one from another. That's why a cat and dog cannot mate for example.
Well you see there randman, that's where you are wrong. Cat's and dogs differ up at the genus level. Tiger and Lion would be a better example and we all know they can mate.
In any case, species is a blurry line. From the wiki:
Definitions of species
The definition of a species given above as taken from Mayr, is somewhat idealistic. Since it assumes sexual reproduction, it leaves the term undefined for a large class of organisms that reproduce asexually. Biologists frequently do not know whether two morphologically similar groups of organisms are "potentially" capable of interbreeding. Further, there is considerable variation in the degree to which hybridization may succeed under natural and experimental conditions, or even in the degree to which some organisms use sexual reproduction between individuals to breed. Consequently, several lines of thought in the definition of species exist:
* A typological species is a group of organisms in which individuals are members of the species if they sufficiently conform to certain fixed properties. The clusters of variations or phenotypes within specimens (ie: longer and shorter tails) would differentiate the species. This method was used as a "classical" method of determining species, such as with Linnaeus early in evolutionary theory. However, we now know that different phenotypes do not always constitute different species (ie: a 4-winged Drosphila born to a 2-winged mother is not a different species). Species named in this manner are called a morphospecies.
* A morphological species is a group of organisms that have a distinctive form: for example, we can distinguish between a chicken and a duck because they have different shaped bills and the duck has webbed feet. Species have been defined in this way since well before the beginning of recorded history. Although much criticised, the concept of morphological species remains the single most widely used species concept in everyday life, and still retains an important place within the biological sciences, particularly in the case of plants.
* The biological species or isolation species concept identifies a species as a set of actually or potentially interbreeding organisms. This is generally the most useful formulation for scientists working with living examples of the higher taxa like mammals, fish, and birds, but meaningless for organisms that do not reproduce sexually. It does not distinguish between the theoretical possibility of interbreeding and the actual likelihood of gene flow between populations and is thus impractical in many instances of allopatric (geographically isolated) populations. For example, it is possible to cross a horse with a donkey and produce offspring, however they remain separate species”in this case for two different reasons: first because horses and donkeys do not normally interbreed in the wild, and second because the fruit of the union is rarely fertile. The key to defining a biological species is that there is no significant cross-flow of genetic material between the two populations.
* A mate-recognition species is defined as a group of organisms that are known to recognise one another as potential mates. Like the isolation species concept above, it applies only to organisms that reproduce sexually.
* A phylogenetic or evolutionary or Darwinian species is a group of organisms that shares an ancestor; a lineage that maintains its integrity with respect to other lineages through both time and space. At some point in the progress of such a group, members may diverge from one another: when such a divergence becomes sufficiently clear, the two populations are regarded as separate species.
* See also microspecies under apomixis, for species that reproduce without meiosis or mitosis so that each generation is genetically identical to the previous generation.
In practice, these definitions often coincide, and the differences between them are more a matter of emphasis than of outright contradiction. Nevertheless, no species concept yet proposed is entirely objective, or can be applied in all cases without resorting to judgement. Given the complexity of life, some have argued that such an objective definition is in all likelihood impossible, and biologists should settle for the most practical definition.
Species is hardly a line cut in stone, and many times species classifications have been changed, or merged. I belive it is disputed weather or not bonobos are the same species as chimpanzee for example.

Re: More species misconceptions
In reality, groups interbreed or reproduce within the same group.
To a large degree this is true, however there are many notable exceptions. Someone mentioned ring species earlier. And despite your belief that this is somehow rare, you would be incorrect. Such anomalies are found throughout the spectrum of biology.
Insects that change their sex, or have multiple reproductive cycles. For example, aphids sometimes reproduce viviparous or oviparous depending on the time of year.
Certainly, there are LIMITED exceptions where, for example, one can breed various plants together, but even there, there is still a discrete group involved. There is just some exceptions within that group.
BS. There is no such thing as LIMITED exceptions, the whole of the biosphere is an exception. You see things too black and white, the fact is every organism, group of organism, and individual is peculiar in it's own right. Taxonomy paints a very broad brush and isn't always perfect at capturing those intricacies.
I think if you were honest with yourself and took a step back to look at how groups of creatures are organized within different groups, you would see that the spectrum analogy is a poor one.
It isn't.
Where does squirrel end and where does squirrel begin?
For example, I know of no other species humans can breed with.
Do you?
Ya, chimps. It's highly likely we can interbreed, the only reason we haven't is probably for obvious ethical reasons.
If the spectrum claim was accurate, we should be able to mate with our nearest species.
Humanzee.
