Mark,
It is evolution, not necessarily adaptive evolution, but it is evolution. Neutral theory & genetic drift are non-adaptive, are in no way related to fitness, yet are still evolutionary mechanisms.
Only in the loosest possible sense of the word evolution (i.e. change over time). Certainly not in the sense of The Theory Of Evolution. What makes the theory useful, powerful and compelling is Natural Selection, any definition of evolution that misses that out is missing the point.
Yes, genetic drift and neutral genetic change occur and any general theory of evolution must take account of the; but they are not in themselves evolution. Thus JIM's statement "evolution can be aptly defined as the change in allele frequency over time" is false.

Mr Jack,

I agree that natural selection makes evolution compelling, but it isn't the whole story. There are both morphological & genetic characters that don't owe their prevalence to ns. It is still change over time, still evolution. Even your own examples change over time.
I think you are wrongly equating evolution with adaptation (in a pure sense). If butterflies with a particular wing vein pattern are replaced by another wing vein pattern, it is evolution even if drift or the founder affect was causal. Meaning drift & neutral theory can be the chief agents of evolutionary change for particular characters in some cases. You can't write this off as not being evolution.
Certainly not in the sense of The Theory Of Evolution.
Certainly is! They are synthesised as a part of the ToE, they can't be separated from modern evolutionary understanding. Pick up any modern evolutionary textbook.
If evolution is based on heredity, & the basic unit of that process is the gene, then allele frequency over time is a perfectly valid definition for evolution. Ultimately even macroevolution is explainable with this definition (lots of micro). It is a bit reductionist, I'll grant you, but valid nonetheless.
As far as I can see, the only real falsifying data would be non-allelic DNA having a phenotypic affect, & that very much depends on how you define gene or allele.

Mark,
I think I've overstated my point. You are correct: change in allele frequency over time is part of evolution. However, I think any definition of evolution (in the sense of the theory of evolution) which fails to mention Natural Selection has missed the point.
While you are correct in stating that adaption and Natural Selection are not the only parts of Evolution, they are the only parts which are capable of producing the finely tuned, adaptive and complex organisms we see around us.
If evolution is based on heredity, & the basic unit of that process is the gene, then allele frequency over time is a perfectly valid definition for evolution. Ultimately even macroevolution is explainable with this definition (lots of micro).
Not so. Large scale evolutionary change, particularly adaptive change, requires a coherent mechanism for change. ToE provides this with Natural Selection. Mere 'change' is no explanation.
Regards,
Mr. Jack

I guess what we need to find out is whether JIM meant to define the Theory of Evolution, which you and others have aptly defined/described, or the word evolution (biological, that is).
They are separate entities, are they not?

Mr Jack,
Large scale evolutionary change, particularly adaptive change, requires a coherent mechanism for change. ToE provides this with Natural Selection. Mere 'change' is no explanation.
I agree, but it can all be reduced to a "change in allele frequency". The mechanisms are unimportant to the definition, that's the job of the more expansive expositions. Even if certain mechanisms are more important under certain circumstances than others. A definition of evolution needs to be as short as possible, & as encompassing as possible. Natural selection, drift, etc. all do the same thing, they change the frequencies of alleles. It doesn't matter how complex a thing that ns can come up with, ultimately, at the reduced level all it's doing is changing allele frequencies. Looking at it the other way, complex morphological & chemical change is achieved by changing allele frequencies over time (plus naturally occuring variation, of course), so what's wrong with pegging the definition at the common genic level? I don't see how this is false.

Mr Jack says:

You're absolutely right. 'Evolution' should be defined by the observation of this change in allele frequency, but I don't think anyone's claiming that this definition explains anything. As an analogy, I think 'the colors of the visible spectrum' is an adequate description of a rainbow. However, the mechanisms of molecular structure and optical refraction are necessary to explain the phenomenon.
Natural Selection is what explains changes in allele frequency, etc., and Darwin's Theory of Evolution by Natural Selection is the framework for understanding the patterns of change we see in the intricate complexity of life on Earth.

Re: Engineering special: take whatever it has at that point.
"The change in allele frequency over time" isn't a summary of evolution, and it isn't an explanation; it's a definition, in that it delimits what counts as evolution (as far as biology is concerned). Any process that involves the change in allele frequency over time is evolution, and any that doesn't isn't. Thus neutral genetic drift is considered part of evolution -- whether you think it's interesting or not is up to you, but it's still evolution. Phenotypic changes that aren't associated with changes in allele frequency (like the increasing height of humans in developed countries over the last 100 years) are not evolution.
This does not mean that all of evolution can be reduced to changes in allele frequency, and it also doesn't mean that the definition is perfect. Speciation is an important part of evolution, but it cannot be described solely in terms of allele frequency changes, and in fact need not involve any change in frequency at all.
When people object to evolution, of course, they're seldom objecting to allele frequency changes. What they're objecting to is common descent (something that involves allele frequency change but does not necessarily follow from it), and the explanation of change in terms solely of natural processes (mutation, natural selection, drift, etc).

A questionable Darwinian Sentence
The problem "with that Said", namely "hearing" a "darwinist" 'say' or rather NOT BE ABLE TO SAY IN A WAY THE popular public "hears" means even that if Provine, or in this case Mayr said "to me" BRAD MCFALL (of take any writing of Carl Zimmer for that matter on evolution) (a me who has spent all he can to understand the verbiage and acutal discussion in EVOLUTIONARY BIOLOGY) UNDER EVEN the topic "The Evolutionary Synthesis as Unfinshised Business" both "Even Wright did not come to grips with the problem of the multiplication of species in his shifting-balance theory, nor with the macroevolutionary problems generated by speciation" and "Despite their tendency to think in terms of phenotypes, they eventually came to view the genotype as a system of gene interaction - that is, they recongized the cohesion of the geneotype - and tended from the very begining to deal with evolution hierarchially." while THE NEXT PARAGRAPH opens with the sentence "BY NO MEANS ARE ALL CURRENT INTRA-DARWINIAN CONTROVERSIES REMNANTS OF THE OLD GENETIST-VERSUS- NATURALIST FEUD." This leaves me completey open to the possiblty that even nothing the evolutionary author could have intended with all this information that it adheres TO ANYTHING at all. It may with a certain "parsing" of the first two quotes I lifted ONLY IF THE FIRST opening paragraph sentence whent UNWRIITEN. BUT I HAD TO GO TO UNIVERSITY TO EVEN UNDERSTAND THE ENGLISH NEEDED TO SEE THIS IN PRINT!!
The problem is that there is ONLY a small insular elite community of evolutionary biologists which is like the Plumber Union with respect to form-making. We all need plumbers if we do not want to abort whats in the drain but if it rains in spain we dont want only the plumber on the plane but this enlightend group speaks for ALL of us biologically speaking. SOOOOOO, if it is unfishised, if we dont know how the bones are acutally really articulated, why must I be shunt off to the no man's land of Layzell's go and look biogeography for I can agree with Mayr that speciation uses simultaneous (not Some wacky relativity metaphyics I some times have to press here when you guys arent listening) "geography" and 'genetic changes of population effect'. I have looked at this down to the letter and still some pin points so it must be my turn now. I am not Job. And still most here feel I but produce "verbiage". The thread head simply wanted us to do away with it totally. I guess if I didnt care I would drive to this place as well.

Re: Engineering special: take whatever it has at that point.
Excellently well put. There are a myriad of mechanisms available for explaining the change in allelic frequency whether you are looking at the microscale (mutation, recombination, drift, etc) or macroscale (natural selection, character displacement, ecological release, adaptive radiation, sexual selection, founder effect, density compensation, the "island effect", etc) which taken together can create related species as different as Elephas falconeri and E. maximus - the former being the world's smallest (now extinct) elephant at only a meter tall.
Don't confuse defnition with mechanism.

The view in question is quite orthodox. Your lack of education on the topic is painfully obvious when you question this. The common ancestor might be said to be an ape, but is not a chimpanzee or gorilla or any other ape alive today. Does than answer your question?

Hehe. That is a mess of replies. As for Darwinists, I believe they are largely dead. There is no cult of personality around Mr. Darwin, great though he was. He was a groundbreaker but his work was incomplete and sometimes even wrong. That's science for you. We update and change ideas as the evidence motivates us.
quote:

You can't understand it, which is not surprising. It is obvious that you have not educated yourself sufficiently to justify an objection. You don't have to agree, but your disagreement is hollow and meaningless until you understand the relevant concepts.
quote:

Actually, what is hollow is your incessant appeals to incredulity. Brilliant scientists may be wrong in certain areas of speculation, but their methods have been refined for centuries to detect flaws in reasoning or methods.

I think the word you're looking for is "deduction." Unfortunately, one can only deduce from nature what one already believes about a deity. Funny how the only people you ever hear claiming that nature will lead us to God are the ones who have already been led to him by other means....

Are you saying that the long list that you posted is evidence of a fish evolving from humans, that is what you said if not implied.
Technically, I do not dispute the existence of the evidence you posted, I marvel over the fact that people , smart people have taken the time to discover and itemize these things. Yes this is science, but the simple issue is what does it mean and the leap of your final conclusion is what I and many others dispute. Being a creationist I credit a Creator initiating the process due to the sole fact that such creation could not be so amazing unless there was an intelligent Being behind it. This is a deducement I realize, but science deduces a lot of things especially the existence of celestial bodies.

Actually, that "humans came from apes" (as we know apes today) is a creationist misconception of evolution. Present-day apes and present-day humans evolved from the same ancestors - *both* have diverged. I like how TalkOrigins puts it, in response to someone asking "If we are decended from apes, why are there still apes around?":
" The question is rather like asking, "If many Americans and Australians are descended from Europeans, why are there still Europeans around?" "
quote:
What is that common ancestor ?
Pick your "ape". Family trees don't all branch off at one point. Organisms are constantly having genetic deviation, but are kept together by niche. When niches diverge, the species becomes reproductively isolated, and cladogenesis (the splitting of a species) occurs. Most splits die out in the long run, but a few become quite successful, and diverge many times further. The common ancestor between ourselves and (insert "ape" here) is the point where that particular split occurred. The real challenge is to get a fossil species along the exact lineage, and not a sister species (although you can still see the evolutionary pathway even if you end up with sister species fossils at a given point)
quote:
Also, I am surprised at the lack of response to your reply by other Darwinists. What is your response when they vehemently disagree with what you said in the reply I am responding to ?
We agree with him. We didn't evolve from apes. We evolved from their ancestors.

I would encourage you to take a course to learn the basics of paleontology. Just like in forensics you can learn a lot from a crime scene based on "incidentals", you can learn an awful lot from a bone.
For example, we can tell which of our ancestors walked upright, which were quadropeds, and which were in-between. I'm sure you just assume that it's pure speculation when you hear it, right? Again, there's that knowledge gap: for a bipedal species, the sockets for the leg bones will need to be putting their pressure parallel to the spine, while for a quadroped they need to apply pressure perpendicular. Thus, you can look at the sockets to see where pressure is being applied and how they are free to rotate, and determine how the animal typically walked.
There are literally thousands of different things you can determine by looking at a well-preserved skeleton. This is where "study" comes in, and why it takes years of college and years in the field to become a competent paleontologist.
quote:
It just seems like they will conclude anything and everything but God.
You do realize, I assume, that the original paleontologists were creationists? As the fossil record was uncovered, however, there were some significant concerns. Species, no matter where in the world you looked, were always sorted into layers. The sorting was completely irrelevant to size and shape. Why, for example, would you always find grasses above trilobytes? It made no sense. So, a theory was developed.
Evolution, right?
No. "Multiple creations".
They were so set on seing the work of God in the world that they proposed a theory that was pretty much accepted, that God had actually made "multiple creations", and then destroyed all of creation and made new versions that looked similar to older versions.
However, they kept having to increase the number of creations over and over, and the graduations between species kept getting smoother. Eventually, it was only a matter of time before evolution was formalized and accepted.
quote:
They can DEDUCE like crazy except the one deducement that God requires which is that what is made was deliberately made so that one could deduce that a Creator made it. {Romans 1:20}
Unfortunately, unless God is a prankster, all of the scientific fields keep running into data that contradicts that.
Why, Willowtree, did God create only isotopes on earth that have half-lives longer than a few hundred million years (i.e., will have dissapeared by 4.5 billion years) or are part of a decay sequence? What reason would he have to do that? We can create, and see created elsewhere in the universe, these "missing" isotopes. But they're all gone here.
Why would God sort the fossils as such, so as to force scientists into at first accepting multiple creations, and then finally evolution?
Why would he match up radioisotope dating - even if you believe that they're all in error (despite confirming each other) - to dates that confirm the "missing isotopes"? In fact, due to radioisotopic dating, Geologists were arguing that the Earth was old even when physicists were insisting that it was impossible. The sun, they said, could not be billions of years old. Why? They didn't know about fusion at the time, so the model that they proposed for how the sun worked involved only gravitational collapse (which powers young stars). And yet, the geologists were completely convinced, based on radioisotope dating, that the earth was billions of years old, despite another branch of science stating otherwise. Then, fusion was discovered, and yet another piece of evidence came into play: the sun matches up exactly in composition with how it would be if it had been undergoing fusion for 4 1/2 billion years.
Why did God create stars that are billions of light years away? I'm sure you're thinking, "How do we know they're that far away?" Here's 26 completely different methods, all of which just happen to confirm each other. Some have been in use since ancient times; some are more recent. Again, it's the reason why it takes years of college before you can understand just *why* scientists are so convinced as to the realities of the universe: everything fits.
Why are there no stars with contents that indicate that they'd be older than 14 1/2 billion years? It's quite possible - indeed, many observed stars could keep burning for tens of billions of years more. But none are older than this - there's a sharp cutoff. Why?
Yes, God could have created light en-route from stars that are billions of light years away, and made all stars look as if they're a range of ages from zero to 14 1/2 billion light years old. God could have sorted fossils in the ground from no conceivable method, and rigged all of the minerals in the planet to give false dates. He could have stripped the planet of all isotopes that would decay completely on a multi-billion year old earth, just to finish off the gag.
But why? Is God a prankster?

Logical fallacy: argument from authority.
I know nothing of Richard Milton and his credentials are very much in question here. Even if he were a freaking Nobel Prize winner, it would be bad form to assert that something is true just because he believes it. You had better have an understanding of the facts behind his supposed belief if you want them to mean anything here. At the very least, you need to paraphrase the facts he cites, and tell us why they are relevant.

Only a very small portion of the earth surface environments that have existed are still resting near the surface today. Only a few of those saw the right conditions for fossils to be preserved. Only a few of those have been explored. Need I continue?
We are lucky we have anything (pray tell, how many modern humans do you expect will end up fossilized?) and what we have still tells us that there have been many distinct species of primates with varying degrees of the qualities that distinguish us from other apes. Cranial capacity and upright locomotion are two of the major ones, and there are fossils which simultaneously follow both these continuua (and which correlate to radiometric dating of the fossils) between us and chimp-like organisms. Tentativity dictates that we refrain from calling this a direct line of descendants. It appears that the lines have branched and many have ended in nothing, and there are probably many missing fossils. However, the general trend of selection over the millenia has favored the change from australopithecines to modern man. Try the thread "A Line of Skulls for Mike the Viz" if you want to know more.
