me I tend to stand wiith evoloution is a feature or by product of Creation or even the Tool of Creation, Ive never seen why God and evoloution can't co-exsist.
I mean the humans evolved from mud thing? wasn't Adam made of dirt or dust?

Well, if you check out strings of protein and a single-celled life form, the onylrecognisable difference is that the cell has a cellulose wall around it. That's why viruses are a great example - some are enclosed in cellulose, some aren't.

Correct. Brains evolved as a result of the cortex being the place where nerve signals were transmitted from, and at some stage, became able to store information.

If you imagine a tree, which is alive but has no brain, and a snail, which is alive and does have a rudimentary brain, there isn't much difference in "intelligence". A tree loses its leaves in winter because different receptors notice the changing temperature and the DNA is coded for leaves to fall off. A snail is reacting the same way to its environment, but through a different system.

The evolution of animalian intelligence is mirrored by computers, but in a much shorter time span, obviously. Early computers were incredibly slow and ineffectual compared to the present day. I recall seeing one 40 years ago which took up a whole room, but took 2.5 hours to do a payroll I can now do in about .1 of a second on my laptop.

That's nothing to do with evolution at all - beyond evolving the ability to make those decisions. All that does is prove that morality isn't hard-wired. Some people have no morals.

As to the dominant ones killing all the submissives, I don't know whether you follow the news pages at all, but it's still happening. Check out Rwanda for selfish genes at work. Another excellent example I have locally is the Moriori - a tribe which were exterminated by other tribes. And as to Hitler, he had a pretty good go at wiping several races out.

All you need to do is ask...

In fact, the links already given cover an enormous amount of transitional species. Archaeopteryx is a favourite as the transition between dinosaurs and birds, but if you've missed data on transitional species, you haven't been looking hard enough.

Seek and you will find!

Incorrect.

Yes, there have been a couple of bad errors and a fraud, but overall, the science is strong. Again, you need to be aware of the miniscule number of animals which ever become fossils. Not having all the data is a strength, not a weakness.

There is not a single piece of published data which refutes evolution.

Nothing is higher or lower than anything else in evolution. We might be smarter than insects, but they have some pretty cool systems which work - bees & ants, for example. Most insects can cope with temperature extremes and after having survived for ~350 million years, I don't see them dying out anytime soon.

---

No, a tyransitional species is a species which has undergone mutation in a successful way and which then mutates again to become the new species. Refer archaeopteryx again.

Evolution isn't a result of species interbreeding - although there could be a case that it has happened in the past. The point was that similar species, which could breed - tigers & lions, for instance, and which have bred in captivity - just don't do it.

Because only the strong survive, it tends to look like a goal-based system, but that's an incorrect way of seeing it. It just is.




I've been looking into the subject for over 40 years and disagree with you. The excellent web resources available also tend to refute the idea. I'm nobody's botanist, but I think it is possible to have a lay understanding of the subject.

Just as you don't need to be a nuclear physicist to understand an atomic explosion, I don't think a degree in botany or genetics is essential to understand evolution.



I started the thread because of some comments in a religious discussion showed that people still have been taught evolution by people biased against the fact that it exists. Country of origin is irrelevant.



And that's just the kind of misconception which abounds and which creates the opportunity for misinformation.

Flowering plants appeared after mammals, does that make them "higher" than mammals?

The ladder doesn't show any feature of evolution, and since the earth will probably be around for a few billion years yet, it would be a little arrogant to assume that we're at the top of any chain beyond the food one right now. We've ruled the earth for a few thousand years while dinosaurs held complete control for over a hundred million years. Check back on that idea in several hundred million years time.

---

Again, here you go off trying to form your argument based on a fallacy of your own. Yes, plants may have formed after primates, but the plants we have now have progressed, evolved, from the plants that were there before, as to better fit their environment, and adjust to changing environment. That is a form of progress, as progress means a progression, I.E. something that changes slowly toward a different thing. You are the one who said we are at the top, and, as for now, we are, as we are more evolved from the previous primates that we were before - we are better fit for survival, which is the key function in evolution. You are assuming a morality on it, to try to disvalue the progressive element, but even if we have gone toward something that is harmful, we have still progressed to it, the same way the bacteria have reformed themselves to combat against our previous methods of destroying them. The ants have progressed, the amoebas in the water have progressed - everything has. The chain of being is the construct that doesn't work, not the progressive process.

Nope, you've completely misunderstood.

Coelacanths are almost totally unchanged after ~350,000,000 years and many insect appear to be identical to hundreds of millions of years ago. Things only change if a mutation is beneficial, and some forms of life are fine as they are. Ferns are much the same after half a billion years.

No fallacy.

You seem to be stuck on the incorrect idea that evolution is goal-based. That it isn't is entirely demonstrble by looking at species which have become extinct, thereby refuting your notion of constant improvement. It just doesn't work the way you seem to have in mind.

I agree it's confusing, especially when you look at human achievement, because it makes progress look exponential, but that's to do with maths, not evolution.

JBI, interesting enough, Darwin was under the romantic age...
he reluted to use the term evolution. Exactly because it implied the notion of progress (which mean getting better). But Evolution was a term already accepted and he only published his 20 years research because Wallance adressed to him a letter saying he would and the term Evolution was there. So, he had to accept (being no great writter, he had not the capacity to create anything to replace it).
It was a romantic age, and Evolution just fell on the right laps, but as scientific theory, it was mostly misunderstood - Darwin never meant it as progress, unless the progress is the sucess of survival. An amoeaba is as much envolved as human beings. Obilivious, I am talkilng from the point of view of someone interessed about Darwin impact (imeasurable) on culture, and texts (his great father being a relevant poet talking about evolution already) beucase it is, in my opinion, one of the most relevant shfts of our cutlure and misundertood texts ever.

Take it easy Atheist! A little more empathy might help in the recruitment.

I don't see how JBI made the mistake you're suggesting. Ferns reached how they are via a progression (from how they were before). You have introduced some sort of conflict about whether a stable form can be reached. JBI didn't bring it up. I figured it out by looking closely at what was written. You seem to have a habit of beginning your "arguments" with zippy attempts at humiliation. But if you slow down a bit and read carefully, you'll see that JBI actually makes the connection between progress and changing environment. There's no suggestion that unnecessary or non-beneficial changes are occurring.

Atheist wrote (further back)

Just as a divert, I think human intelligence is a dead end and that we'll die out. At that stage, some species will take our place at the top of the food chain.

Well, technically right, I guess, but in no way deserves the "another mistake" that kicks things off. Re-reading the topic that you're addressing when you mention human intelligence's possible dead end, you are directly addressing humanity's prospects for evolving into something else, and how something else might replace us. Is being at the top of the food chain related to evolution? If not, why did it cap YOUR argument about the prospect of further human evolution. I mean, I can see why JBI might've gotten off course...

OK, I'm not going to go back and hunt through and look for this, maybe I really am getting this wrong but if there are intermediate forms/stages in evolution, and a certain, now-extinct, primate was a direct ancestor of humans, is it really 'out of bounds' to say that the surviving, better adapted, human being is more evolved? If we can't say that, I think it would be a great service to tell us just how we should describe this very important relationship in a discussion about evolution.

Here, I think your (the Atheist's) response is pretty accurate, as far as it goes. The bacteria didn't purposefully reform with the goal of combatting efforts to destroy them--and this is an important point. Kudos, I know it's easy to get the wording wrong about this, even if one is perfectly aware that evolution is not about goals. In retrospect, it's easy to look back and see all of the competition going on, and give the creatures too much credit.

However, I don't think your example of 'extinct species' proves the point. It proves that those particular species didn't take on mutations that would have saved them from extinction, that's all, leaving aside whether or not they had been purposely trying (and failing) to take on those mutations/changes and evolve to some goal or another.

Also, just as important, it appears that the main point that JBI is maybe making in this quote is to reassert a lack of intermediate forms. Anyhow, I think the bit at the end about the "chain of being" is his main thrust. Anyhow, you don't address this here (because you got side-tracked, maybe?) so it might have been good to restrict the size of your quote to the mistake that you decided to address.

You actually did address the intermediate forms issue a few posts back, however, and you addressed it well, but chose to end your argument with the unfortunate, "Not having all the data is a strength, not a weakness." I think it would have maybe been more accurate to say that not having all of the data was "understandable" or "no surprise", instead of "a strength."

Atheist, you make great points, are passionate about your position, and just the sort of voice that makes things fun sometimes. But, sometimes, if something looks a little wrong, an ounce of re-reading and an effort at empathy can maybe help bring a focus to the areas of misunderstanding, and make it easier on those who have maybe misunderstood something. And sometimes, with just a little bit of generous reading, the content and context supporting a perceived error might be found to exist somewhere other than in what's actually been written.

Ok people, I bet more than half of you can already guess what I am going to say :
BREATHE, :D
and take a step back. Don't get mad or offended, reassess and if you can't help but get very seriously annoyed then you need to consider whether it is really worth even coming to look at the thread? I can't see how it matters what other people think either way myself but I know that some people do so all I can say is breathe and let it go. Its far healthier than getting mad.
:D

I personally don't see how it matters how we've come to be in this point of History, but what matters is what we do with our lives when we have them.

I can't resist pointing out that we have no measure of intelligence other than our own and just because we can't perceive intelligence there doesn't me there isn't any. Kind of like did you know monkeys speak in dialects and regional accents? There was a study done a few years a go that discovered this, it makes a good nature-nurture debate point.

---

umm this seems to be a point in favour of Intelligent design. Surly evolution wold just continue because mutations do happen anyway, and surely you would find offshoots as well? A bit like an oven and a cake.
In the beginning it takes a fair bit of tweaking to get the conditions right for optimum baking, then its all hands go and everything is going smoothly the cake is both rising ad setting and its all good. But take it out too soon and it is underdone, but if its left in too long, it spoils. so what makes evolution stop when something is 'just fine'. What turns the oven off?

Ok how about you explain goal based evolution and this other evolution you are talking about and the difference between the two because I am well and truly confused now. :confused:
And do me a favour and keep it fairly simple and straight forwards so I can follow?
:D

To those who don't believe in evolution, it is pretty simple, I would say. If you just think about it in terms of change, you can see how it's necessary. The nature of everything in the universe is change. How could a species, be it a plant, or animal, or insect, remain unchanged through millenia? Everything is in constant change, even if the change is very gradual.

And, evolution is quite observable. Fruit flies, deprived of light, lose their ability to see within a short number of generations.


I missed quite a lot in this discussion - I can't see what JBI and Atheist are arguing about, for one - but what is interesting to me is what is the future of evolution. Sri Aurobindo wrote a wonderful chapter or essay in one of his books about evolution. Actually the main of his work was about humans gradually evolving into the next step. He said, would a primative ape, living in his tree, be able to comprehend that there would one day be a creature on the earth who could shape metal, make cities and civilizations, cross the oceans and fly through the air, change his outer and inner environment, and make laws according to reason? And if he could grasp this, could he understand that such a creature would eventually come from what he was then? A pretty safe assumption is no. And it's fairly obvious in this light, that there is the possibility of future evolution. Of a higher humanity, as far ahead of us in terms of evolution as we are from our ancestor.


Oh, and as for most evolved, we are not the most evolved. One thing I heard was... Whales can withstand incredible pressures in the ocean... they are highly evolved... because they have been in their environment for, I don't know the exact numbers, but quite a lot longer than humans have been on land.

Sorry Night. What I meant was, evolution holds that we came from "primordial ooze," and are not the creation of an omnipotent Designer. With that as our background, there is no higher authority but the highest intelligence there is - which is humankind. The reason I don't think that God created, ah, ooze then let evolution take over is because there's nothing in the Bible that says He did, and it isn't logical to assume, either. Because if He did there would be death before sin.

Evolution does not say anything about primordial ooze. Evolution is something that happens with living organisms, so, before the first living organism, you do not talk about evolution.

---

That is simple minded to say at least, survival of the fittest is not the theory of evolution, it only a slogan used in the debates trying to resume it. Anyways, not only humans are able to show what we can generosity and obviously, honesty and integrity are related to human societies and not a biological event.

Obviously, anything is only fit to a specific task. For example, Pele would not be fit to play basketball but he was for Soccer. A bug small size allow him to occupy spaces where pretadors have more difficulty to reach, where he can find food and being smash-able, I am sure a Whale consider us very smash-able too.

Quote:

---

Why not? Why don't they do it?

---

They do it. But the chance of survival of the result of a couple even between close specieis is reduced. Plus, many of those offsprings that manage to be an addult have problems because of this, genetic, and generate no offspring. Plus, why a tiger and a lion do not breed (considering how rare is one to find another outside a zoo) is because they smell different, have different color, do different noises and "enjoy" different sexual activities. Just like, most of the humans, are aware that a chimp is different from a woman. But hey, some dont... such is life.

No, we are not. Do not insult anyone listing the differences, because evolution is the existence of such differences, which are not a ranking of the "The Dearest of Mother Nature".
It is not about being better, so any attempt to list differents to prove our mighty power over amoebas is not getting the point and just a bit ridiculous.

This thread is amazing! Who wants a Darwin award?

Well, it's been going ok for the past 20 years. Empathy's more for HR practitioners than recruiters - recruiters are just high-class pimps.

If we can't say that, I think it would be a great service to tell us just how we should describe this very important relationship in a discussion about evolution.

---

This is the nub of the issue, and it is a difficult concept, because we're looking at it from a skewed preception - human - and at one particular instance in a billions-of-years process.

You have to look beyond time and see evolution as a process which sometimes happens and which sometimes does not. As I've tried to point out, having more talent/ability/limbs/brains than another species confers no special rights or place on that species.

The expression "more evolved" doesn't exist, because it doesn't describe anything.

---

You're getting this one wrong as well, or maybe just putting it wrong, because mutations don't happen to save species from extinction - they just happen. A mutation for less fur may happen at the same time as a period of global cooling.

The way you've written it, it seems to indicate that the genes have some idea of what challenges they're facing, which they don't, of course.

We agree that there's plenty of evidence, so that's good.

---

I see what you're saying, but I'll stick with strength, for the following reasons:

The theory is still fluid enough to be fine-tuned within new evidence.

It proves that the theory is factual, because the gaps are covered by predictions, which have so far turned out to be correct when later fossil evidence is found.

It shows the rigour of the hard science involved.

It protects against claims of bias or fabrication by scientists.

It would be a lot easier in some ways if we could line all the fossils up, but challenges are good!

Surly evolution? Is that how men become grumpy old farts?

:D

Almost all "offshoots" die because the mutation isn't advantageous. Again, the miniscule fraction of animals which end up being fossilised means that there is no fossil record of these.

On the other hand, offshoots are as common as primordial soup - humans, gorillas, monkeys and chimpanzees are all offshoots of a common ancestor. One we haven't yet discovered, although the German fossil last week is promising.

---

There is no cook, no mixture, no timing, no "done". Mutations happen; successful ones may become a new species, the others die.

Evolution stops when the sun explodes or there is no life left on earth.

You seem to be looking at it from the wrong angle.

---

Well, there is no difference, because there is no such thing as goal-based evolution.

Evolution happens. It either works out or doesn't.

Nope.

The cellulose is there because those cells are more successful than non-encased ones, although if you've ever had norovirus or rotavirus, you'd probably agree than non-encased cells have plenty of power and aren't scared of anything.

Absolutely, but excellent example, because it allows me to bring in cats, birds and other animals which grow or shed hair & feathers in reaction to the weather changes. Birds don't decide to get their winter feathers in, it just happens automatically from coding in the DNA.

:lol:

Apologies, I confess that I put that one in there to see if it drew out the old creationist canard.

It did.

There is a difference between organic and inorganic molecules and how they behave. If we constructed Boeing 747s out of organic molecules, it might well grow back together!

Isn't that what we should have evolved into?

---

As I look around me, that appears to be the case!

If no other animals had social groups, you'd have a point, but worker bees don't ask the queen whether they were designed to the job, or whether it's just in the genes. Lions, gorillas, elephants, dolphins.... most mammals have distinct social structure and within those structures, you can see all the types of behaviour you've described.

Nope - if traits were universal, there wouldn't be worker bees. We also still have no idea on what the split of personality type is regarding nature/nurture, so it's not too surprising we can't point to certain genes just yet.

No! You should enjoy and embrace it.

Again, it shows the rigour of the science - you don't get a free pass with sceintific discoveries, you have to prove it, then prove it again.

The trick is to look for actual scientific argument and avoid the cries of deniers who think it's all a big hoax anyway. If you stick to the former, you'll find that the disagreements aren't usually about whether a species is a transitional one or not, it's whether it's the particular one claimed. Science, like any human endeavour, is susceptible to hubris, and no scientist wants to let a colleague take glory he'd reserved for himself.

I'd really like you to try to get this one part into perspective.

At present, human discovery has led to several hundred fossils of butterlies being recovered. That's several hundred, in the whole ~300,000,000 year history of butterfies.

How many butterflies do you reckon have lived in all that time?

I can't even begin to think of how big a number it is, yet we have a lousy 300 say. Yet, from those 300, we're trying to make information fit the billions of butterflies alive today, plus, the trillions and trillions that have ever lived.

Is it really that surprising that we have so little evidence of what actually happened along the way?

Given the little evidence we do have, I'm constantly awed by the brains which manage to connect the few dots.

Evolution is like doing a puzzle of the Mona Lisa in one-pixel pieces. Yet, we're finding, as time goes on and discoveries are made, that almost all of the pieces are in the right place.

I'm hoping my rationale for that, because it really is.

Take homeopathy as a counter example. Its total weakness is its inflexibility. To make a 30C solution work, one has to do it to a formula which would make a widow weep, so no respectable scientist can be bother with failing to replicate the results they don't get. Accordingly, homeopathy flourishes in no scientific minds beyond its use as a placebo.

Evolution, on the other hand, is an open book; many an amateur fossil-hunter has made an earth-shattering discovery. One woman in NZ found a fossilised tooth in a stream-bed a few years back. Turns out she'd found the first incontrovertible evidence that large carnivores existed on our land mass, with a big t rex-looking beatie of 30' length. That tooth is available to study and be debunked in a way that pseudoscience and metaphysics can only dream about.

It depends on the environment. A lucky combination of oxygen, atmosphere and gravity have let us assume the beautiful forms we occupy. A methane-breathing species on a huge planet with a gravitational pull 10X that of earth is likely to be one flat, ugly sucker.

Insects have done pretty well in coping with the earth's changing faces over hundreds of millions of years, so I expect them to be able to cope in whatever the future holds.

You don't need to list differences, because they're irrelevant.

We're more intelligent and better-looking than amoabae, but we are not "more evolved". We're both alive today. You could make an argument that we're more evolved than dinosaurs since they died out, but in terms of species alive today, no one is "more evolved" than another.

Oh quite. Well, all this thread has done for me is raise even more questions about evolution and therefore cement creationism. Sorry.

On my final note, I have to say I find evolution rather insulting. My faith has me as the child of the King, while evolution has me as the child of an ape. Or sludge.

Enjoy the rest of the discussion.

Of course it doesn't. That's just a straw man argument, as I'm sure you know.

Even so, the date of the origin of angiosperms is unclear, and may be earlier than previously thought (i.e. in the late to middle Jurassic, rather than in the Cretaceous.

This thread has gotten contentious and somewhat off topic, but Camilo has hit the nail on the head.

Darwin never tried to answer the question, "Where did life come from?" Other scientists have addressed that question (e.g.Oparin). Darwin's theory of evolution is simple but profound, involving the following ideas: 1) There is variability in the characteristics of living things; 2) Living things produce offspring that manifest the physical characteristics of their progenitors; Living things produce offspring that manifest the physical characteristics of their progenitors; 3) There is a struggle for survival of living things that involves competition for envirnomentally determined reasources (food, mates, etc.); and, 4) "Success" in this struggle for survival is determined by the ability of an organism to reproduce offspring that themselves survive to reproduce. The whole process is called "Natural Selection." It is like the "Artificial Selection" of plant or animal breeders, but the selector is the natural environment rather that, say, a breeder of Airedales...

It's really as simple as that. Simple, but a profound scientific insight. BTW, the idea of evolution by natural selection doesn't have to be limited to "living things." There are, for example, computer programs, like The Game of Life, that allow self-replicating programs to "evolve" under various "survival" constraints.:yawnb:

Quite right. I've tried to make it clear that all numbers are totally approximate. When you're talking a margin of error of millions of years, I wouldn't plan on celebrating any birthdays too soon!
