First, someone stated something about dogs and wolves being able to breed and alluded this to something having to do with evolution. I would like to point out that wolves are still dog kind.

by this logic, humans could have come from apes. both humans and apes are primate kind, and related by over 98% DNA similarity.

if you start with a primate kind creature (say a chimp) why can't you end up with another primate kind creature (say human)?

using your logic, it is clear that humans descended from apes, another primate kind animal.


Since neither Creation or Evolution can truly be scientifically proven (if you question this you don't know the definition of science) both are belief systems about the past based on a certain interpretation of the evidence we have today, in other works it is a faith based world view.

no, sir.

evolution can be disproven. creationism can not. thus, creationism is not within the realm of science and evolution is.

evolution is based on facts and data, and the interpretation thereof. it has nothing to do with faith.

it is a theory that explains the facts as we know them. as the facts change, the theory will change, and that's what makes it science.
 
Lamont, sorry I mis-quoted you. And I probably do need better reading skills!

Soggy, I will send a note to the speaker who gave the lecture with the names he quoted. I realize that vertical change is evolution and that is what is not seen, just changes within a certain kind.

As I will go back and find the specific references concerning the transisional fossils I would ask you to also provide your reference to the lots and lots of them that you site.

It is interesting that you refer to the Cambrian Explosion as it is when from out of almost nowhere there are all these fully mature fossils of various kinds but no transisional ones. You would think that there would be some kind in this same strata for all the supposed millions and millions of years that these fossils cover but there aren't.

You say "What we know is that species evolve over time and eventually can become new species. " I would like you to state or site specific evidence that one species has turned into another.

And what I mean by proving it scientifically was that per the definition of scientific theory you can demonstrate what it is you are trying to prove repeatedly. Here is the definition from Wikipedia - Science in the broadest sense refers to any system of knowledge attained by verifiable means.[1] In a more restricted sense, science refers to a system of acquiring knowledge based on empiricism, experimentation, and methodological naturalism, as well as to the organized body of knowledge humans have gained by such research. In this most basic sence you can not prove evolution as you can not do it in experimentation or observe it in nature right now.

I look forward to you reply!

Warthaug:
However, it isn't that simple. In your example evolution should occur very fast, as you have a small population (so mutations spread quickly) and strong selective pressure (i.e. 0.1% survival). This could drive the formation of a new species much more quickly (several hundred, to thousands of generations). But with ~0.1% survival, I'd expect extinction to be a more likely outcome of your experiment.

But I would end with the same statement I made last time - evolution does not have to lead to new species. There are many possible outcomes, from speciation, to extinction, to remaining the same species for a very, very long time.

Bryan

Perhaps it wasn't a well defined example using the clown fish. But you defined strong pressure selection which was my point....perhaps 1 or 2% survival? :D
Would it be possible to monitor changes in DNA in each generation bred under the pressure, using PCR? One could record changes over say, 10 generations and exrtrapolate that in XXX many more generations, we would now have only 90% common genes? (in 10,000 years?) and thus a non compatible breeding capacity with parent stock DNA?
Evolution does not HAVE to lead to new species but it had to have many times.
My whole reason for this question is, as you can guess, is that if this is how new species develop, then it's happening right now in some animals. It must be. And just because a new species came to be, the parent stocks weren't necessarily wiped out. Perhaps only separated. But this is the big question that Creation asks. At some point, literally overnight, the offspring of a parent strain, changed enough that their babies born could not breed with the original parent strain where their parents still could, which perhaps, on another continent which had no selective pressure, or less, still exist.
 
AevnsGrandpa:

no sir, you are incorrect.

first, evolution can not be proven. it can only be disproven.

second, there is an overwhelming set of data that supports the theory of evolution. while new facts may change details as to how we understand evolution, the theory of evolution itself has surived countless scientific challenges over the years.

but you know what? if tomorrow we find some facts that show that evolution is wrong, i'll be the first one to say evolution is wrong.

that's what science is all about.

We have, multiple times.

"No" transitional ones is completely false and is claim made over and over again. It is *wrong*.

Read the links in this section on fossils to find out why you are totally wrong. It is incredibly annoying that creationists continue to lie about this.
http://www.talkorigins.org/indexcc/list.html#CC300

You would think that there would be some kind in this same strata for all the supposed millions and millions of years that these fossils cover but there aren't.

Well, no. The conditions for fossils to form are rare and finding those fossils is even rarer. Transitional animals only exist for short periods of time, thus the odds of them being fossilized is very low. Even with all this, we have transitional fossils.

You say "What we know is that species evolve over time and eventually can become new species. " I would like you to state or site specific evidence that one species has turned into another.

Please read the dang thread...it has been done to death.

Yes we can. It has been experimentally tested in labs. Before perpetuating more lies, please go back and read the thread, especially Warthaug's posts as he does this for a living.

explain the following for me:

roughly 20 million years ago there were no primates

roughly 17 million years ago, we start to see primates

where did the primates come from?
 
Hi H2Andy,

So your saying that because creationism is a "faith based" view of the evidence that it can not be disproven and therefore not science? That doesn't make sense to me. We all have the same evidence right now here on the earth to look at and from our view or belief of the past and how the present came to be we interpret what the evidence means based on that view or belief. How we interpret the evidence has everything to do with our preceptisions (sp?) on what we think happened.

it is a theory that explains the facts as we know them. as the facts change, the theory will change, and that's what makes it science.
What facts are changing? Are they facts if they change or speculations?

AevnsGrandpa:
Last time I posted this thread was only at 192 pages!

I just read back a few pages and noted a few things I would like to bring up.

First, someone stated something about dogs and wolves being able to breed and alluded this to something having to do with evolution. I would like to point out that wolves are still dog kind.

Perhaps you should re-read what I wrote there, as you obviously missed the point. The point there was the evolution can occur without the formation of a new species. Evolution lead to the difference between dogs and wolves, but they are still the same species.

As for the rest of it - you should have read back a little farther, as we covered the "kind" issue about a week back. "Kind" is useless as a scientific criteria as it is too subjective, and too prone to redefinition, to be useful for any sort of comparison.

In the previous example humans/chimps and horses/donkeys were used as examples - with someone claiming the first were not of the same kind, while the second were of the same kind. However, the genetic, structural, biochemical and immunological similarity between chimps and humans is far, far greater then the similarity between horses and donkeys. So that persons definition of "kind" clearly represents a personal opinion, rather than an objectively definable criteria. If donkeys and horses qualify as "kind", then by quantifiable standards (i.e. scientific standards), humans and chimps are also of the same "kind".

AevnsGrandpa:
What some may say is evolution is nothing of the kind (no pun intended) There is a huge amount of "horizontal" variability with in the different species (kinds) which gives us everything from wolves to poodles, but they are still just dogs.

Do you even know what evolution is defined as? It is simply, and succinctly, the change in the genetics of a population over time. Nothing more, nothing less. And those changes have been observed time and time again.

Don't forget - scientific theories are just our explanations of the FACTS which we observe. That life (and its genetics) change over time is an absolute, undeniable FACT. Each and every FACT we have recorded agrees with evolution, and no other theory which explains these FACTS has been proposed, either here, or in the wider world. You have to either provide a better explanation of those FACTS, or show those FACTS to be false, to disprove evolution. Not one creationist, in the past 300-odd pages (or for that matter, in the last 150-odd years), has done either.

AevnsGrandpa:
I just attend a very well done conference on this subject and per quotes from leading evolutionary scientists there has yet to be found any intermediary fossils found in the fossil record.

And who is this scientist? What research have they done in the field of evolution? On what topic? Where are their studies published? I think we all know the answer to this - none.

After all, any "leading evolutionary scientist", or for that matter, anyone who's ever walked into a museum, knows that claim is a load of horse huey. Literally thousands of transitional fossils are known, and recorded in both the scientific and layman's literature.


AevnsGrandpa:
Thus we have no vertical change, one species to another,

Wrong, again. There are over 2000 speciation events recorded within the scientific literature. Your claim that the formation of new species has not been observed is out of date - by 101 years. That's right, the first speciation event was observed in 1905. You may even have the product of that event in your garden - the evening primrose is the product of that speciation event.

AevnsGrandpa:
but lots of horizontal change due to adaptability and natural selection (which is not evolution).

Actually, it is evolution. Creationists like to redefine what evolution is for some reason. But rather then demonstrating what evolution is, all they demonstrate is their ignorance of evolutionary theory, and for that matter, science in general.

I'll repeat it again, as hopefully repetition will drive the point home - evolution is the change in a populations genetic makeup over time.

Here's a few other definitions, from reputable sources:

"change in the gene pool of a population from generation to generation by such processes as mutation, natural selection, and genetic drift" - dictionary.com

"A progressive distancing between the genotype and the phenotype in a line of descent." - Stedmans medial dictionary

"he way in which living things change and develop over millions of years, or a gradual process of change and development" - Cambridge dictionary

Evolution is a scientific theory. You can redefine it all you want, and claim that your definition is true or false. But at the end of the day evolution is what the scientific definition says it is - too be blunt about it, your personal opinion of what evolution is means nothing.

AevnsGrandpa:
Since neither Creation or Evolution can truly be scientifically proven (if you question this you don't know the definition of science)

That you make this statement shows that you do not understand science. Before you get all excited I should point out that I am a scientist. I do medical research for a living. I publish scientific papers, in scientific journals. I teach science to university students. I have lived in the world of science for over a decade - science puts food on my table, pays the rent, and even buys my SCUBA gear. And I can say, without reservation, that evolution is scientific in nature, a valid scientific theory, and while we're on the topic, one of the strongest scientific theories from the point of view of supporting evidence.

Lamont,

I'm sorry you have gotten into annoyed at me, while I have read many pages of this thread, I have not been able to keep up with it and read all 392 pages. If I am asking or stating things that you have heard before and have to repeat you message before, I'm sorry.

I will look over the web site you had and try to surf through the postings that Warthaug has put up.

Jeff
