Quote:
Why would a species that is doing so much for its own survival (everything) be happy with evolving into not existing by becoming something completely different ? The emphasis should be placed on life as a force and not a collection of indivdual species.



I dont think animals or plants make a conscious effort to go extinct. Its just bad luck that they live in a time when some toxic environmental change has their number on it. 99.9999% of species that ever lived are extinct. Thats a scary prognosis for anything.
WHY? -I dont buy your "conscious decision "belief , everything lives in the plesure of geology, so we cannot predict for "life in general" . WE can predict for spcific animals when we see their niche degrading so that their numbers begin to plunge. For animals that evolve, I believe that a specific minimal amount of time is required so that several generations can "do something different" with theor equipment. If you look at Galapogos finches, it seems to be a matter of available food resources. Certain finches have developed beak types that fit the newl;y offered foods, and the beaks just became modified via the same genetic response that described their original beak shapes.
I would look up the evolution of "Sabre toothness" to get a more exhaustive review of present thinking

I dont think we know exactly what happened. I would call that process ABIOGENESIS, not evolution. Once the first cell appears, then were talking evolution. Thats pretty mush what science says. As I said, I dont make the rules of the game.

Why do you never understand the argument ? That is my argument. If several species are all tied to rain forests and the rain forest dies out, then there are several species down the gurgler. Having multiple species and their very specific dependancies, is worse for a family than to have one species which is dependant on very broad requirements.

Quote:

So to you an amoeba is just as complex as a human ? Have you been reading some leftist version of biology or are you pre-empting what you think will be an ID argument by an anti-IDer ?

Quote:

Perhaps that is because I didnt say it. I didnt even suggest it. I am saying it is major flaw in evolution to suggest there is a mechanism whereby species change to survive without mentioning that by changing they cease to survive. An explanation of that conflict would do well to promote understanding of evolution.

Quote:

FYI, that amount of time is believed to be around 3-5,000 yrs on an average.

Thank you, but I am very familiar with the evolution and re-evolution of sabre cats . Your whole attitude of recommending reading for me I find very condescending. If it continues, I can recommend several good books on how to collect rocks.

Quote:

So the process of survival for chemicals that are the basis for life is of no concern to evolutionists. Chemicals that use other chemicals for their protection/survival is not the forerunner of evolution let alone evolution itself ? This process by which life thrives is dependant on a classification process invented by man ? Or perhaps evolution was there affecting which chemicals would react and still be stable enough to enable life to develop. Perhaps the process occurred and then its application arose. Like gravity in deep space....it doesnt need matter/energy to exist but its affect is more discernable with the prescence of matter/energy.

@Ionus,
It has now become obvious that Io has been acting the "good cop" to fm's "bad cop" in the power game on behalf of "left functionalism" which represents a takeover of the state by the lower-middle-class to which they both so self-evidently belong and attempt to represent. Just as the real middle-class took over from the aristocrats in the 18th and 19th centuries so the lower-middle-class now seeks to supplant it and introduce centralised and rationalised social control based on the temptation that we will all be "led to safety" if we accept the rhetoric and the structures it calls into being and expands.

That is the key to understanding the debate on this thread, and the other one. Such a transformation, which we can all see everytime some petty "expert" appears, usually in a uniform of one sort or another, to invade our lives, reduce our freedom and stifle the natural creative and entrepreneurial spirit. The dead-hand of bureaucracy with well paid jobs for all who toe the line. Such a key subsumes and explains all the rest and is grounded in the overall political economy.

All the rhetoric of benevolence is of little significance and derives entirely from the dynamics of the key transformation being attempted and which can only be halted by its own internal contradictions resulting in a financial meltdown. The notions of the generation of capital and the stabilty of the system have been lost sight of.

That is obvious from the focus of both Io and fm on peripheral technicalities such as we are now witnessing and their refusal, presumably grounded in either fear or ignorance of what they are about, to discuss whether what they are proposing will work and will benefit society.

And I am not even saying it won't. I am merely asking that they justify it and the fact that they turn away from the question with alarming alacrity, and eagerly dive into any one of the vast range of esoteric byways at their disposal, a species of Ignore, strongly suggests that the question "will it work?" makes them insecure. Which is, at the least, grounds for suspicion that they don't know whether it will work or not, or, what is even worse, they have not even considered the matter. We are being asked to take their word for it despite Robert Burns.

Does it even work in relation to their own stated objectives? Will their own idealised objectives bear fruit given that the lower-middle-class can hardly be blessed with much more than an average IQ of 100 due to its size and is guaranteed to be pursuing its own interests with each section of the bureaucracy in battles for supremacy and even survival.

That Io and fm are now in a cosy relationship after their initial vicious spats demonstrates that no particular fundamental principle motivates their positions and that the new starter, Io, has been tamed and brought into the fold tempted by opportunities to strut his stuff.

He's an anti-IDer and that's all there is to it and my advice to him is to get fully onside anti-ID, with Ms Forrest, and knock off pretending he can arbitrate the two sides because he can't. It's a seminal issue. All that he can expect from having a foot in both camps is that his legs get further and further apart leaving his sensitive spots exposed.

The professional class rule society. They took over whilst the social classes thought it was a struggle between themselves.

You are wrong if you think there is a social class struggle out there. The lawyers, doctors, bankers, etc all have their hierarchy and good machines rise to the top. There is no social struggle left. You are in your 100 yr old books and need to look around. Politicians are dummies...they rely on academics and professionals to tell them what to do. The professionals control their own.

That's what I was talking about.

And I don't think politicians are dummies. What's the use of saying "good machines rise to the top" without saying what "good" is. The safe pair of hands rise to the top in bureaucracies. We know what "good" is politically in a functioning democracy. Media is also advised by academics and professionals to tell it what to think and how to present the academic and professional viewpoint. No Prime Minister's Questions under parliamentary privilege.

You just confirmed all I said.

If that was your argument, you need to work on your skills at developing it. Firt
Why would all the species of a genus be clustered in the same niche? The whole point of multiple species is that the genera have evolved several "Answers " to the adaptation problem. Its a mathematical fact that more species of a genus means that the genus is able to better wether these violent changes of the environment. EO Wilson has estimated that, based upon "latitudinal gradient laws", over 300000 species of beetles alone exist on the planet. No doubt, each one is microadapted and several have probably gone extinct since Wilson documented them.

Unlike you, I feel quite confident and secure in my skin. I wouldnt feel the least bit threatened about you serving up some texts on rock collecting. I find these kinds of books quite useful for the locality information.

I merely suggested that you read Raup to get an exhaustive review of your sticking point. (WE hqave neither space nor facilities here, and I feel that Id be letting something out )

Quote:

Im not sure that your use of "no concern" is accurate. Lets say that , the SPECIFIC theory has nothing to do with abiogenesis. Also, Im not sure that the molecules were "adapting" (if they were theyd be proto life already.

Theres too much workd being done in so many fields that its impossible for any one person to spread themselves out thinly . I have a single discipline and I only read into others that have value to my area of work. I dont follow whats going on in abiogenesis. If you wish to insist that I should be personally involved to be a better geologist, Id say that you have no idea about what the pile of **** I already have to carry around and use so that I can earn my meals and reputation.
I have colleagues who work in molecular bio and organic synthesis of life and I usually see them on holidays or get preprints of an article that someone submitted to NATURE. Im curious , but not too involved. Verstehen?

What an utterly ridiculous thing to say. Is that how kids will be taught to express themselves if anti-ID comes to power? Lord help us. It's even inconsistent with anti-ID philosophy which is that the more "work", not defined of course, the better and that thin spreading is ideal for confusing the voters.

@Ionus,
What you are doing Io is allowing the case to be conducted as it was at Dover. The prosecution sets the agenda and the defence tries to deal with that and nothing else completely ignoring, for professional and personal reasons, that it has an agenda of its own. Such a strategy lost at Dover and will lose anywhere else.

There are no half-measures or neutral grounds. You are either for atheism and the eradication of religion from the socialisation process or you are not. And if you are not you are for ID. End of story.

And if you are for anti-ID join your esteemed colleagues on here and get on message. It is worth your while in that case to read back on their contributions so you can get the hang of it.

BTW--On the NFL broadcast on Thankgiving Day there was a sequence dedicated to the troops abroad. It ended with "God bless you all." Perhaps the NFL, which doesn't piss-ball about with words, tests are objective, is basically religious in orientation.

That would be a turn up eh? The religious are objective and the atheists are as subjective as they can manage without it looking too obvious to the under 10s and the senile.

Excerpts from a recent essay on teaching evolution:
Quote:
Why Are There Still Monkeys?
(William Eric Meikle and Eugenie C. Scott, Evolution: Education and Outreach, December 2010).

Popular misconceptions about evolution seem to have a life of their own. Some of the most common ones have persisted for decades, despite all efforts to correct them. Some of these ideas seem to be firmly embedded in American culture—or sometimes to have even deeper roots in the Western historical tradition. They are passed on from generation to generation, typically outside of formal and informal educational institutions. These are not necessarily or distinctively creationist misconceptions. Rather, they are simply very common among students and the general public, regardless of what their beliefs may be about whether evolution has occurred. Educators need to be aware of and ready to counter such common misconceptions. Unless they are explicitly pointed out and debunked, they will persist, coexisting with standard concepts of evolution that may be learned in the classroom.

When talking to the general public or school groups about human evolution, we have found that if you discuss evolution or answer questions about it long enough, one particular question will inevitably be asked. That question, of course, is “If humans evolved from monkeys, why are there still monkeys?” This is sometimes phrased in terms of “apes” instead of “monkeys,” but the technical differences between these groups of primates are irrelevant to the significance of the question being asked and the unspoken assumptions that underlie it. Besides, it is not at all clear that most of the public can tell the difference between an ape and a monkey, as illustrated by the numerous portrayals of “monkeys” in the media by chimpanzees. One of us has described this question as “probably the second most common question I get on talk radio.”
.
When first encountering this question, it may not be clear how to respond. Why shouldn’t there still be monkeys? What is the questioner thinking? After repeatedly confronting this question in various guises, we have recognized that it derives from a mistaken view of evolution shared by many people, including students. Its persistence among the general public suggests that many retain this view even after instruction in evolution.

The “why are there still monkeys” question reflects an interpretation of evolution as a series of progressive steps, from simple to complex. It sees modern organisms, whether living species or other groups, as representatives of the ancestral “stages” or “steps” of evolution, or even as the still-surviving ancestors themselves. This popular misconception often includes the unspoken assumption that the appearance of descendants must coincide with, if not result in, the disappearance of ancestors. One must change into the other, without any coexistence of the two. The unconscious model of evolution that appears to be the default mode for a great many people thus seems to be both linear and anagenetic.

What is missing from this view of evolution is the crucial role of branching or splitting in creating the tree of life. Perhaps the easiest way to introduce a more accurate model of the relationships of contemporary species is through the analogy of human family categories, and especially that of “cousins.” Students often don’t recognize that they have two classes of relatives in their own families, lineal and collateral. The progressive, ladder model of evolution highlights only the lineal relatives: grandparents, parents, children, grandchildren, etc. However, collateral relatives such as cousins, aunts, nephews, and so forth are also family members. In any large extended family, it is likely that the majority of relatives will be collateral rather than lineal ones. So too in the extended family of all living things.

The notion that living species are cousins, and neither ancestors nor descendants of each other, is one of the most important understandings for students to acquire. This relationship results from the branching nature of evolution and reflects common ancestry. Those who ask why there are still monkeys implicitly conceive of the relationship of monkeys, apes, and humans as a lineal one where monkeys evolve into apes, and apes evolve into humans. This is incorrect on many levels, of course. First, it usually pictures living monkeys and apes as part of this linear trajectory, instead of ancient apes and monkeys. Second, ancient monkeys didn’t evolve into apes. Monkeys from the New World are only distantly related to humans and apes, but even Old World monkeys didn’t evolve into apes. Apes and Old World monkeys descended from a more generalized anthropoid common ancestor that lacked the derived traits of either monkeys or apes. Sometimes scientists refer to the common ancestors of modern apes and humans as “apes,” though it would be clearer to students if we were more careful to distinguish such ancestors from living forms, perhaps by consistently referring to them as “fossil apes.”

**************************************************

So how should teachers and professors respond when confronted with the question, “if humans evolved from monkeys, why are there still monkeys?” Sometimes this and other questions about evolution are encountered in a fleeting context where there is not quite enough time to explain the full scope of evolutionary biology! The briefest possible response would be to emphasize that evolution deals with common ancestors. It is not that humans descended from apes and that apes descended from monkeys; rather, humans and apes share a common ancestor, and it is more recent than the common ancestor they both share with monkeys.

If you are in a classroom situation where you have a bit more time, use the analogy of a human family tree. It is no more correct that humans descended from apes and that apes descended from monkeys than that you descended from your siblings who in turn descended from your cousins. No one would ask, “If you evolved from your cousin, why is your cousin still here?” The question “if humans evolved from monkeys, why are there still monkeys?” is equally absurd to an evolutionary biologist.

Where it is possible to use diagrams or other illustrations, you can reinforce the point by noting that genetic information supports the genealogical relationships of the primates as more or less distant cousins: apes and humans are genetically closer to one another than they are to monkeys, just as an individual shares more genes with a sibling than with a cousin.

As with all misconceptions, this one will not be laid to rest without making students grapple with the conflict between their misconceptions and the scientific data. And of course, misconceptions remain resistant to change without the repeated reinforcement of accurate science. In this context, it is critical that teachers present evolution not as a linear sequence but as a branching and splitting pattern of lineages, with the end products being cousins.

This the most pernicious misconception, and we've seen it here again and again. People seem to be offended, too, that it is said that we are descended from "monkeys." Of course, nobody who knows what they are talking about says it. I've seen it so often in people who come here to do the hit and run thing.

Yes. That's why I made it. And it isn't just my position. Anybody who thinks religion has a useful role to play in society must give it some sort of status in schools. As the teaching of evolution to adolescents undermines religion and has little use what are the arguments for it. Those interested in this tiny corner of science have as much material as they could wish for. Why push it onto those not interested in it and on those opposed to it?

How would atheists inculcate discipline when its source is secular and subject to electoral revision? Such conditioning can easily be seen to be in the interests of the conditioners. Which, in view of the 70 years post school world, cannot afford to be revised and thus electoral revision becomes questionable. One would need a high degree of continuity.

But there is also the possibility that a secular definition of discipline imposed by the class benefitting from it will breed increased deviancy and thus create more jobs for other "experts" in social control mechanisms who are sure to come from the same class as that of the conditioners. Lower-middle-class job and power expansion.

I don't think science or evolution theory have anything to do with your promotions wande. I think they are politically and economically motivated. And they are not even good at it.

Setanta cannot mean me. I don't run. He hits and then uses Ignore. Or has done and not yet repented. That's basic "hit and run".

So who does he mean? I've not seen anybody saying we are descended from monkeys on here for months. Maybe years.

Nor have I seen for a very long time anybody asking why monkeys are still here.

His argument about nobody knowing what they are talking about saying those things is entirely circular because he defines knowing what they are talking about the way he wants. Thus meaningless.

And it is worrying for anti-ID that he seems unaware that circularities are meaningless.

It is a series of steps. Whether they are "progressive" is another matter. Where the authors are mixed up is conflating in their own minds what is happening within the organic structures with the categories the species have been placed into by people like themselves for the sake of simplicity and management of their subject. The actual animals are continuously evolving in real time by a series of "steps" some of which contradict others.

Quote:

I would describe that sentence as ridiculous. It can only have been written by someone who can't handle the language. I presume "shouldn't" is a typo.

The organisms, apart from man, don't recognise those categories.

Good luck to any teachers who follow that up. Tough luck on the kids.

I think the real reason most people think we are descended from monkeys, for those who do, is our profound similarity to them. That explains our fascination with them.
