You have posted quite a lot - in fact, more than anyone else. Therefore, you have provided more clues about yourself and your mindset than anyone else here has.
Do you think obsessing about what I’m like suggests something about you?
I could offer some comments about what I can see and what I know about you from your posts.
Wouldn’t it be great if we spent a little less time focusing on those motes in the eyes of others? Just a suggestion.
Do you have a spiritual director or a regular confessor that you work with to improve your spiritual life?
Yes. I go to a rather small parish, and we aren’t all that sophisticated as to have personal spiritual trainers. He’s my priest, and my friend. Will that meet your requirements?
If so, you might mention to him that fellow Catholics in this friendly discussion have complained about your attitude.
I guess it would be only fair to mention that it’s folks who object to the church’s teaching on the acceptability of evolution, one of whom is promoting Krishna Consciousness “science” as an alternative to evolution. Do you think that would be an important thing to add?

Barbarian on the practice of obsessing with ad hom:
It just confirms what your messages have already told us.
I’m not sure if I’m included in “us”
Anyone who cares to observe the behavior.
What do you think your messages have told us about yourself?
That I’m not inclined to go with “Krishna consciousness” for one thing. For another, that I accept the Church’s teachings on science.

Things like that. What do you think your rather obsessive interest in my personal life says about you?
 
Barbarian, your position on issues would be better respected by those you hope to convince, if you treated those people with respect instead of ridicule and contempt.
Perhaps if each of us acted in a charitable way, there wouldn’t be a problem, um? I’m thinking that “You’re the problem, and I’m not” isn’t the best way to go. Just a suggestion.
I have no horse in this whole evolution / ID / creationism race.
I see the denial, but your behavior is more eloquent.
It appears as though you cannot stand to have anybody disagree with you - the expert.
Perhaps you’re a little out of joint, because the evidence didn’t turn out the way you wanted? Do you think you’d get a little more respect if you dealt with the evidence, instead of how angry the Barbarian makes you?
Perhaps it is your worldview and pride that is threatened.
I don’t think counter-accusations are going to do you any good at this point. If you can’t bring any evidence to the table, going ad hominem isn’t going to help you.

It just makes things worse for you. Get over your hurt feelings and try to put a cogent argument together.
 
Do you think obsessing about what I’m like suggests something about you?
I don’t see any “obsessing” in this case. I was responding to a post from someone else who was discussing your on-line personality so I didn’t even raise the topic.
Wouldn’t it be great if we spent a little less time focusing on those motes in the eyes of others? Just a suggestion.
There is a time and place for fraternal correction or just simple interest in the welfare of the other person. Certainly, I’ve read more writing from you than anyone else on this topic (evolution)-- you project your personality in every post and there are many posts. To suggest that people should also take no interest or concern in your own personal life at all is unreasonable. You’re a human being and we’re Christians here (mostly). We’re taught to care about the other person and not merely treat the person as an anonymous post-generator of some kind.
Yes. I go to a rather small parish, and we aren’t all that sophisticated as to have personal spiritual trainers. He’s my priest, and my friend. Will that meet your requirements?
Ok, thanks. It’s the perennnial spiritual teaching of the Church that we should seek spiritual direction whenever possible. Certainly, in a small parish it’s not always possible. But there might be a monastery in driving distance or a parish with more priests. In any case, you used a somewhat depreciating term “personal spiritual trainers” to make it sound like this is an extravagance or an unnecessary thing. The lives of the saints teach us that spiritual direction (that’s the official term for it) is essential for growth and it’s only a very rare few saints who didn’t have a spiritual director. This is similar to a regular confessor – or your parish priest who is a friend.
I guess it would be only fair to mention that it’s folks who object to the church’s teaching on the acceptability of evolution, one of whom is promoting Krishna Consciousness “science” as an alternative to evolution. Do you think that would be an important thing to add?
Yes, I do. It’s important to try to find out if the people who are compaining are the ones who are wrong or if you are (or perhaps both are). This can be hard to do by yourself, and that’s where a confessor or director will help. I’m not a neutral observer so you’ll probably dismiss what I will say, but I agree with some others here about your attitude. Again, you will probably disagree but I really do not think this has anything to do with your scientific ideas or philosophical views. Like Ricmat, I’ve disagreed and argued with many people on a variety of subjects including this one and I’d just characterize your attitude as condescending and having contempt for the people you oppose. You might say that I am guilty of the same thing and if so, I apologize and I will try to improve.
That I’m not inclined to go with “Krishna consciousness” for one thing.
This is a good example. It’s a very defensive reply with a touch of anger and attack. But more importantly, I wouldn’t say that the first thing your posts tell me is that you’re not inclined to go for Krishna consciousness. I actually see no indication that you’re interested in that topic, for or against. You don’t write much of anything about your faith that I can see. You’ve actually used a ridiculing term for the concept of spiritual direction. So again, I wouldn’t say that you’re primarily about being opposed to New Age theology. As I see it, you’re primarily about “your science”, whatever that is. You’ve put that in a Catholic context and that’s good – but science is really your passion and first interest (nothing wrong with that as long as it doesn’t replace God). But then after that, your posts say very loudly that you have anger and contempt for “creationists”. This is very obvious. You mention creationists in posts where there was no need to mention that term. It’s repeated sometimes several times in a single post.
For another, that I accept the Church’s teachings on science.
Ok, that’s fine but it’s not really a distinguishing characteristic as I see it. It’s like someone saying that they accept the Church’s teaching on mathematics. You have written quite often about the Church’s teaching on science, but I don’t think you’ve every really put those teachings in context of binding authority or theological status. Some of what the Church says about science is not given at the level of doctrine. Some is merely given as opinion which can change.

But all that said, I agree that the Church’s teaching are a serious concern for you and that does come through in your posts.
What do you think your rather obsessive interest in my personal life says about you?
Well, you’ve used the word “obsessive” twice in this post so I think you believe that my interest in your spiritual life is more than I should have. I don’t know if anyone else thinks that because this is really the first time I’ve asked these questions of you.

That said, I don’t think these (now two) posts on this topic are “obsessive”. Again, I’m involved in many Catholic apologetics discussions (on other boards) and it is very common and expected that one person should be interested in the spiritual welfare of the other. We should pray for each other and hope the best for salvation.

In my view, the person (personal life) is more important than the scientific view that the person may hold. The science will pass away. But the person is an eternal thing. The spiritual life is what is lasting and permanent. Our words will echo through eternity – they’ll be held for our salvation or our loss. So, I think it’s important to help one another on the path of salvation in whatever way we can.
 
I think most of this tit-for-tat personal stuff if off topic.
(unless, of course, that’s what the thread is about!!)

If you make a comment here or there, it’s one thing, but …

If you do have a legitimate beef (but not on Fridays now 😉 :cool: 😉 ), how’s about we just take it to one of the mods, instead of dragging it all over threadspace.
 
I don’t see any “obsessing” in this case. I was responding to a post from someone else who was discussing your on-line personality so I didn’t even raise the topic.
It just seems odd that when we start getting down to the evidence, you want to change the subject to the terrible Barbarian. It looks bad, that’s all.

Barbarian suggests:
Wouldn’t it be great if we spent a little less time focusing on those motes in the eyes of others? Just a suggestion.
There is a time and place for fraternal correction or just simple interest in the welfare of the other person.
And here, I was thinking you were just trying to change the subject. And you were thinking only of my welfare…

Barbarian on inquisition about his spiritual life:
Yes. I go to a rather small parish, and we aren’t all that sophisticated as to have personal spiritual trainers. He’s my priest, and my friend. Will that meet your requirements?
In any case, you used a somewhat depreciating term “personal spiritual trainers” to make it sound like this is an extravagance or an unnecessary thing.
Let’s just say that the parish priest has been the source of guidance for generations of my family, and we never thought he was less than adequate for that purpose.

Barbarian on his critics:
I guess it would be only fair to mention that it’s folks who object to the church’s teaching on the acceptability of evolution, one of whom is promoting Krishna Consciousness “science” as an alternative to evolution. Do you think that would be an important thing to add?
Yes, I do. It’s important to try to find out if the people who are compaining are the ones who are wrong or if you are (or perhaps both are).

Telling me that I should follow Krishna’s “science” is personally offensive to me. Go figure. I don’t care if you are personally arrogant or not. I’d like to keep this argument on the evidence.

Barbarian observes:
That I’m not inclined to go with “Krishna consciousness” for one thing.
This is a good example. It’s a very defensive reply with a touch of anger and attack.
Notice that Wolseley repeatedly refused to tell us about it, but wanted us to “buy the book.” It’s hardly surprising that I mentioned it, when I found out from where his ideas came.

Why would it be surprising to get some criticism for pushing that kind of thing on a Catholic board?
But more importantly, I wouldn’t say that the first thing your posts tell me is that you’re not inclined to go for Krishna consciousness. I actually see no indication that you’re interested in that topic, for or against. You don’t write much of anything about your faith that I can see.
Then you haven’t been listening. But perhaps you’re only interested in one thing here.
You’ve actually used a ridiculing term for the concept of spiritual direction.
As I said, I come from people who always thought the local priest was for spiritual direction. We’re simple folk.
So again, I wouldn’t say that you’re primarily about being opposed to New Age theology.
It’s not “new age”; it’s quite old. And it’s wrong. And you should avoid it, too.
As I see it, you’re primarily about “your science”, whatever that is. You’ve put that in a Catholic context and that’s good – but science is really your passion and first interest (nothing wrong with that as long as it doesn’t replace God). But then after that, your posts say very loudly that you have anger and contempt for “creationists”.
Nonsense. I’ve praised a number of them, like Harold Coffin and Kurt Wise, for their faith and integrity. I have contempt for those who lie and hide their true motives behind “ID.”

Barbarian observes:
For another, that I accept the Church’s teachings on science.
Ok, that’s fine but it’s not really a distinguishing characteristic as I see it. It’s like someone saying that they accept the Church’s teaching on mathematics.
I wasn’t aware that there was a teaching on mathematics. There is St. Tom’s argument that God can’t make a non-Eucilidian triangle, but that’s obviously not true.
You have written quite often about the Church’s teaching on science, but I don’t think you’ve every really put those teachings in context of binding authority or theological status. Some of what the Church says about science is not given at the level of doctrine. Some is merely given as opinion which can change.
Maybe so. But criticism of the Church’s position here, goes beyond the limits for Catholics.

Barbarian asks:
What do you think your rather obsessive interest in my personal life says about you?

It seems odd, since it appears out of the blue, and off-topic.
 
If you do have a legitimate beef (but not on Fridays now ), how’s about we just take it to one of the mods, instead of dragging it all over threadspace.
Well said, and sorry for responding as I did. From now on, I’ll not respond to that kind of thing, (I should have ignored it from the start)
 
Rossum and/or Zian -

You seem like reasonable people to discuss things with, so I have a question that perhaps you can help me with. This has to do with instincts, and/or behaviors.

I’m familiar with the standard evolutionary explanation of how physical characteristics are transmitted, and how they evolve (after all, it’s all I heard for over 50 years). But I’m not familiar with the standard evolutionary explanation of how instincts evolve, or how they are transmitted to the next generation. My guess is that you’ll say that “it’s in the genes”, or “it happens with random mutations and natural selection exactly like physical characteristics”, but, if that’s not the case, could you give me a short explanation and/or some links?

Note: this has nothing to do with creationist web sites, etc. I don’t remember reading anything about this anywhere, so I haven’t been “misled.”

Thanks in advance.

I can see that, you are asking a perfectly reasonable question. Regurgiposts are usually easily recognisable.

Not a problem.

As each generation dies for whatever reason the next generation will have more of the mutation because of that 0.1% advantage. Do a compound interest calculation for two bank accounts, one at 5.0% and one at 5.1%. See what happens after a hundred years. The difference is equivalent to the reproductive advantage of the mutation over 100 generations.

I personally agree more with ricmat, although
I also agree the use of the words “selection kills” albeit not wrong, might be too general. Along with “killing”, natural selection also “prevents” other
mutation from occuring, it seems, and therefore actually “prevents” evolution from occuring.
Darwin’s different species of finch’s would be, in my opinion, an example of this. It seems that the diversity of species existed due to the “lack of environmental constraint” instead of environmental pressure such as predators (There were no mammals and few reptiles on the islands.)

Therefore, it seems that the finch’s were changing because of a “lack of natural selection” at first, until migration to other different
islands started to isolate the different species. This geographical natural selection, which enabled distinct island populations to arise, stiffled, killed or prevented other species to evolve.

Now, while this has nothing to do with the random/non-random mutation argument, it does involve a problem I have with natural selection being the “arrow of evolution”. If the whole world would be a perfect environment, evolution would be much easier to study, not because of natural selection, but because of the lack of it.

Most of the time, it does. It’s called “stabilizing selection,” and during times of constant environment, it tends to dominate over directional or disruptive selection.

On the other hand, during times of change, natural selection produces new allele frequencies by selectively removing some alleles and differentially encouraging others.

No, that’s wrong. What happened was an example of disruptive selection. The finches that arrived on that island were one species, but because of limited resources and unlimited reproductive capacity, the competion for different food sources caused evolution to produce specialized forms. We can see that happening in a number of places in the world now. Would you like to learn about some of them?

There would be no evolution if such a thing were possible. But it’s not. Things always change, and with them, selective pressures. In any given environment, there are always species undergoing changes in selective pressure.

Although I don’t have much problems with the above, I believe that I would differ with the interpretation involved. During “great environmental changes” a greater number of mutants seems to occur. However, would this be due specifically to the environmental changes as being the cause in itself, or whether it is due to the organism reacting, as a defense mechanism, in order to survive? It seems that neo-darwinsm cannot explain why a greater number of mutants would exist.

I fail to see any competition involved within the environment the Galapagos Islands was able to offer. What I would be able to understand would be a thriving population existing among the finches specifically because of the lack of competition, which, gave ample time to produce different species. The selective part was, in my opinion, on the side of the "finches " choosing as a preference only the island which accommodated the best for it’s food source supply.

Any resources you are willing to give would be appreciated, Barbarian.

That’s not what the data show. Name me a population of animals or plants for which this happens. Keep in mind, that during environmental changes, we would expect the allele frequency of a population to change, but not the mutation rate.

Organisms do not have mutations in order to survive. There is no intent at all on the part of the organism. It happens in the bodies of the parents, when the egg and sperm cells form.
It seems that neo-darwinsm cannot explain why a greater number of mutants would exist.
More might survive. But so far, no one can show that any animal or plant population has shown any increase in mutation rate in response to selective pressure. There is some unconfirmed data which suggests that bacteria might have evolved a way to increase mutation rates when stressed. But they are a lot older than animals and plants are.

Sorry, no evidence for that.
Any resources you are willing to give would be appreciated, Barbarian.
You might want to first read “Finding Darwin’s God” by Kenneth Miller. He’s both a well-respected biologist, and a devout Catholic.
amazon.com/Finding-Darwins-God-Scientists-Evolution/dp/0060175931

Then, of course, “The Beak of the Finch.” Which is a very layman-friendly explanation of the way selection works for Darwin’s finches.

Barbarian observes:

If a perfect environment existed for all forms of life, why would it be impossible for Evolution to occur, in your opinion?
No selective pressure. You’d see fluctuations about the mean, but no direction whatever. I’m intrigued by your capitalization of “evolution.” Was that intentional?
 
Charles Darwin, On the Origin of Species, Chapter Seven - Instinct.
Thanks Rossum, but I actually asked the wrong question - I understand that if instincts are physical characteristics, and if evolution explains how physical characteristics are created/mutated and passed to the next generation then the same would be true of instincts. [not that I buy into that happening in an unguided way :)] But what about the underlying mechanism?

Assuming that instincts, which are complex behaviors, are stored in DNA… How does a protein, or molecule or chemical come to manifest itself as a complex behavior (or even simple behaviors)?

And a note to **mich2 **who said:

Actually, my comment about natural selection killing was made in the context of comparing it with mutations. “Somebody” was arguing that natural selection, by itself, without mutations, could create more complex life forms. I was disagreeing with him.

The point which I was making was that increasingly complex life forms (going from simple life to advanced life) cannot happen exclusively with natural selection, minus mutations. Natural selection does not create new alleles. Without mutations, natural selection can only kill off what already exists, so it does not by itself create complexity. It’s the mutations which create more complexity, which natural selection may then favor (as in, not killing off or killing off more slowly) assuming the complexity is a good thing. For example, a horse with 4 and a half legs is more complex, but probably not a good thing.

For a detailed answer you are going to have to ask someone who knows a lot more about biology than I do. I can give you an example of a simple behaviour: plants reacting to light. In simple terms there is a light sensitive growth promoter in plants. When exposed to light the growth promoter is less effective. Hence the shaded side of a growing stem will grow a bit faster than the sunny side of the stem. This will tend to direct the growing stem towards any nearby light source - it is why you should turn your indoor plants round every so often so that they do not grow all one sided.

For diurnal motion like sunflowers following the sun there is a different system which pumps water into or out of certain cells, thus turning the flower head. Again the direction of pumping is controlled by a light sensitive protein.

You are right in that natural selection does not create new variations. Mutations tend to increase the amount of variation in a population while natural selection tends to decrease the amount of variation.

A mutation may either increase or decrease complexity, but that is of no direct interest to natural selection. Only reproductive effectiveness has any impact on natural selection. In different circumstances either greater or lesser complexity may be more effective at reproduction.

**The Psychophysiological Basis for Two Kinds of Instincts—Implications for Psychoanalytic Theory

John C. Lilly, M.D.
INTRODUCTION

In recent years the brain systems which underlie and produce the phenomena called instinct have been delineated. For the first time the systems, which when stimulated cause either various kinds of pleasure or various types of negative avoiding, painful or fearful reactions, have been discovered and studied in great detail. Work has been accomplished on rats (16), cats (23), (1), monkeys (1), (7), dolphins (8), and in humans (20), (21), which has far-reaching implications for the systematic development of the theory of instincts.

In this paper the levels of discourse must be very carefully delineated to avoid confusion. Experiments using rats, cats, and monkeys involve extremely simple nervous systems compared with those of the human and of the dolphin. The phenomena elicited are completely reproducible. The responses to stimulation of the rat brain are simple and amazingly repetitive kinds of behavioral patterns: the cat introduced slightly greater variabil**
pep-web.org/document.php?id=APA.008.0659A

You have to buy a membership to read more than the abstract, darn it.

The basis for instinct in most animals is structural, in the nervous system, and so the specific genes that (for example) enlarge the problem-solving area of pangolins (which makes them notorious escape artists in captivity) would be responsible for that behavior.

Likewise, the neurological basis for provisioning reflexes in Sphecid wasps is known, but until their DNA is sequenced, we won’t know what genes produce those bits of hymenopteran nervous system.

One thing you can bet on; it won’t be magical.
 
That’s not what the data show. Name me a population of animals or plants for which this happens. Keep in mind, that during environmental changes, we would expect the allele frequency of a population to change, but not the mutation rate.
Well, I would guess the Cambrian explosion, if triggered by a great sudden environmental change, could support such an hypothesis.
Organisms do not have mutations in order to survive. There is no intent at all on the part of the organism. It happens in the bodies of the parents, when the egg and sperm cells form.
I agree; in the sense that a flock of bird doesn’t intend to go south for the winter because it decides
that it would be better for it’s chances for survival. However, the process of migration causes the bird to survive. How exactly the instinctive mechanism works we don’t know, but it has a purpose…
More might survive. But so far, no one can show that any animal or plant population has shown any increase in mutation rate in response to selective pressure. There is some unconfirmed data which suggests that bacteria might have evolved a way to increase mutation rates when stressed. But they are a lot older than animals and plants are.
My personal belief lies in the holistic approach that an organism continuously analyses and reacts to it’s surounding environment, and in doing so, sends signals to certain parts of it’s body in order to regulate it’s metabolic functions for survival purposes. Such signals,I believe might go as far as to regulate the genetic function within the cell itself which eventually could affect the sex cells. During greatly pronounced environmental changes, where the lifeform is in danger of extinction, the process of analysis could, in my opinion. be increased.
…I know this is not science, but a philosophical
approach only. However, It seems that some evidence for some sort of non-random mutation mechanism are believed to exist.

I also agree that changes in animals and plants might be much harder to observe as they are composed of a much much greater number of cells.However, if a bacteria can react towards a new environment through the process of mutation, then so can any other forms of life, I would think.

Here is a link concerning plants, not bacteria.
plantcell.org/cgi/content/full/17/11/2852

Therefore, baffling new observations in plant genetics that challenge current concepts continue a long tradition. One of these challenges comes from the study of heritable phenotypic and genetic alterations that are consistently produced after a flax cultivar has undergone an environmental change.
It’s well-documented. There are limited resources (food, shelter, etc.) and the finches compete with each other for them. Those best able to utilize the resources tend to leave offspring.
Ok; I won’t argue . But my thought was simply that the new environment for the finches must have been much better than harsh since, first no preditors existed, and since those which migrated must have been small in numbers, there must have been plenty of food supply. However, eventually,since some finches which might have been born with a different beak allowed themselves to feed on possibly different food supplies which might not have been adequate enough for a substantial population of it’s species, migration to another island which had better food supply would, in my opinion, explain why Darwin found different species on different islands. To claim that a small flock of birds, lost from the main land separated and came to reside on different islands; from which, each different group changed the physiology of it’s beaks within X amount of generations, of which the survival of the fittest would overcome the other finches, dependant on the difference of food supply, is, in my opinion, a little harder to believe…not impossible, but, harder, still.

It’s the mutations which create more complexity, which natural selection may then favor (as in, not killing off or killing off more slowly) assuming the complexity is a good thing. For example, a horse with 4 and a half legs is more complex, but probably not a good thing.
I fully agree

(Barbarian, regarding the belief that environmental stress causes mutations)
That’s not what the data show. Name me a population of animals or plants for which this happens. Keep in mind, that during environmental changes, we would expect the allele frequency of a population to change, but not the mutation rate.
Well, I would guess the Cambrian explosion, if triggered by a great sudden environmental change, could support such an hypothesis.
I don’t see any evidence there for a change in mutation rate. Environmental change merely favors new mutations. The Cambrian explosion was mostly an arms race after full-body exoskeletons evolved. Stabilizing selection gave way to disruptive and directional selection. But there’s no evidence whatever that the mutation rate changed.

Barbarian observes:
Organisms do not have mutations in order to survive. There is no intent at all on the part of the organism. It happens in the bodies of the parents, when the egg and sperm cells form.
I agree; in the sense that a flock of bird doesn’t intend to go south for the winter because it decides that it would be better for it’s chances for survival. However, the process of migration causes the bird to survive. How exactly the instinctive mechanism works we don’t know, but it has a purpose…
In the sense that a river has a purpose. But that too is a matter of physical laws at work. The purpose of creation is deeper than that.

Barbarian observes:
More might survive. But so far, no one can show that any animal or plant population has shown any increase in mutation rate in response to selective pressure. There is some unconfirmed data which suggests that bacteria might have evolved a way to increase mutation rates when stressed. But they are a lot older than animals and plants are.
My personal belief lies in the holistic approach that an organism continuously analyses and reacts to it’s surounding environment, and in doing so, sends signals to certain parts of it’s body in order to regulate it’s metabolic functions for survival purposes. Such signals,I believe might go as far as to regulate the genetic function within the cell itself which eventually could affect the sex cells.
Beliefs are one thing. Evidence is another.
I know this is not science, but a philosophical
approach only. However, It seems that some evidence for some sort of non-random mutation mechanism are believed to exist.
Can you show me some of this in plants or animals?
I also agree that changes in animals and plants might be much harder to observe as they are composed of a much much greater number of cells.However, if a bacteria can react towards a new environment through the process of mutation, then so can any other forms of life, I would think.
Yes, they can. But they don’t increase mutation rates to do it.
Here is a link concerning plants, not bacteria.

That study does not suggest increasing mutation rates. It suggests that flax may have extragenomic material with genes that can be induced in the right circumstances. A remarkable thing, but not what you are arguing.

Barbarian on natural selection and Darwin’s finches:
It’s well-documented. There are limited resources (food, shelter, etc.) and the finches compete with each other for them. Those best able to utilize the resources tend to leave offspring.
Ok; I won’t argue . But my thought was simply that the new environment for the finches must have been much better than harsh since, first no preditors existed, and since those which migrated must have been small in numbers, there must have been plenty of food supply.
Founder’s Flush. At first, almost everyone survives. Then the place fills up and competition gets tougher. No free lunch.
However, eventually,since some finches which might have been born with a different beak allowed themselves to feed on possibly different food supplies which might not have been adequate enough for a substantial population of it’s species, migration to another island which had better food supply would, in my opinion, explain why Darwin found different species on different islands.
Wouldn’t explain the adaptive radiation of different species on the same island, though.
To claim that a small flock of birds, lost from the main land separated and came to reside on different islands; from which, each different group changed the physiology of it’s beaks within X amount of generations, of which the survival of the fittest would overcome the other finches, dependant on the difference of food supply, is, in my opinion, a little harder to believe…not impossible, but, harder, still.
It has the virtue of being consistent with the evidence. And for science, that’s what counts.
 
The scientific atheism community (which seems to include many who call themselves “Catholic”) will no doubt tell you that ID is not science, it is religion.
More often, it’s Christians who have objected to the religion called “Intelligent Design.” The scheme became clear when the Wedge Document, in which the people who invented ID admitted, that it’s “governing goals” were to establish their particular religious ideas. (which are, BTW, the official doctrine of the Unification Church)
Some creationists have seen ID as “allies” in the fight against scientific atheism, and unfortunately have given ID a bad name as a result. It’s quite possible that they really don’t understand it, but it IS true that Creationism believes in God, and Design would certainly point to a pretty powerful creator.
Creation and design are incompatible. Design is what limited creatures do. And since ID took a YE creationist tract (Of Pandas and People) and merely inserted “ID” for “creationism”, before presenting it as an “Intelligent Design Textbook,” we know that “ID” is just the latest renaming of what has been called “Flood Geology” and “Scientific Creationism.”
You will no doubt get a lot of responses to this thread. I will bow out since I’m tired of arguing with the same atheistic Catholics over the same issues.
If all you have is slander against Catholics, then maybe it’s better for you to leave.
