Questions for debate: Is evolution a fact? Do we know evolution is true? How do we know it is a fact? How do we know it is true?

It will be necessary to define some terms:

Define what is meant by evolution in this context.
Define what is meant by fact in this context.
Define what is meant by know in this context.
Define what is meant by true in this context.

Most would say that evolution is, based on observed data, pretty close to being a fact/true. Fortunately, the theory of evolution evolves as we learn more about our natural world. Overall, these new things don't prove evolution to be wrong, but either a) increase/change our understanding of it or b) show previous claims/thoughts true.
Now then, we can argue about the 'meaning' of terms all day long I suppose. Would it make a difference?
Nope
It's all about what the individual CHOOSES to believe. If one doesn't want to believe in evolution, fine. If one doesn't want to believe in a all creating 'jin', fine. We are each responsible for our own minds and beliefs. Proving one wrong or right only matters to those who wish it to matter.
In other words, if Bob wants to believe 1+1=eggplant, no amount of 'proof' in the world will change his mind until he WANTS it to change. And as long as Bob doesn't try to force me to believe 1+1=eggplant, I don't much care what Bob believes or thinks.

Your house is not a natural object. It's an object that you or other humans have built. So this is an extremely bogus argument on your behalf.

Goose wrote: But then by your own definition of “fact�, evolution (as you define it above) is not a fact, since it has never been observed that a simple single celled critter will give rise to a more complex human or even merely a worm-like critter for that matter.
Actually evolution has been observed countless times. It's been observed in fossil records, and it's also been observed in the laboratory. The truth that evolution is indeed a fact is what keeps doctors on their toes when it comes to trying to keep up with the evolution of pathogens and viruses. In fact, we even see evolution in action dynamically in pest control in insects.

So evolution is not only an observed fact, but it's actually a very real problem that we need to deal with on a daily basis.

Again within the context of rational thought, we can rationally accept that we know something when everyone who share this reality with us reporting the precise same experiences, observations, and artifacts.
Argumentum ad populum. Not to mention not everyone accepts Darwinian evolution. A Scientific Dissent From Darwinism.
If you think this is an argument of populum they you have grossly misunderstood.

I'm not talking about common people on the street accepting things because they are popular. I'm talking about the fact that all scientists who work in these fields have found the same factual evidence, and there does not exist a single solitary scientist who has found any conflicting evidence that can be independently verified or agreed upon.

Clearly you aren't understanding the power of science if you think it's just an argument of populum. Nothing could be further from the truth.
Goose wrote: Great. So all you need to do is trot out all those consistent and reliably repeated observations of where, let’s say, a fish-like critter gave rise to a man.
The evidence for that has already been "trotted out". In fact, it's been posted on these forums repeated by Danmark. I don't currently have the link to those posts but if you like I can PM Dan and ask him for the links.

But what we're talking about here is just common scientific knowledge. You should be able to study this on your own if you're truly interested in evolution instead of just supporting the nonsensical creationism objections to it.

Creationism has no scientific basis. It's solely driven by unwarranted faith-based religious beliefs.
Goose wrote: Well since you claim evolution, as you’ve defined it above, is sound, let’s see that sound argument.
Science has already made the argument. They've done it convincingly and in great detail. Asking me to give you a free college course on the science of evolution is, quite frankly, unrealistic. Especially considering that you are clearly a hostile student who will refuse to accept any and all evidence given to you.

Besides what do you have to offer as an alternative? Absurd male-chauvinistic bronze age mythology? :-k

Sorry, but I see no reason to believe such unproven nonsense.

Humans are apes.

We are one of the great apes on planet earth. We didn't evolve from apes. We are apes that are continuing to evolve. And we aren't done evolving yet.

Evolution happens whether we like it or not. The fact that it happens is observable as is the fact that when enough change happens new species occur. Not surprising since species is just a label we humans put on a set of genetic characteristics.

I don't know whether the path of human evolution is as proven a fact. It could be but I haven't looked into it enough to assess.

However a high school understanding of biology and just a little research into lab studies will demonstrate that evolution happens roughly the way the "evolutionists" say it does. That doesn't mean anything in regards to the specific theories if human evolution except that they are based on a confirmed possibility. I suppose there can be detailed debate about that. But there is too much observable evidence that evolution happens to have a reasonable debate about that. Genetics change over time. A species is a set of genetic characteristics. Species change over time.

I don't think this proves anything about how man has evolved, to do that requires much further examination of evidence. But it cannot reasonable said that species do not change to the point of becoming other species. Unless you are using species to mean something other than what the people who came up with the term mean.

You are avoiding the salient point. Your definition of evolution is entirely circular and easily falsified with a few counter examples which is all I need since you’ve made the definition universal. Don’t like the house counter example? Okay, let’s look at a rock jutting out of river or a tree in a forest. Repeated observations tell me that rock won’t become more complex. It will eventually erode away. The tree will eventually die and decompose not become more complex. Your own definition falsifies evolution.
Actually evolution has been observed countless times. It's been observed in fossil records,
Let’s clarify this shall we? Evolution has been interpreted to have occurred in the fossil record, it has never been observed to occur in the fossil record.
and it's also been observed in the laboratory.
No, the fact is a bacteria-like critter has never been observed to evolve into anything other than a bacteria -- something like a worm-like critter for instance.
The truth that evolution is indeed a fact is what keeps doctors on their toes when it comes to trying to keep up with the evolution of pathogens and viruses. In fact, we even see evolution in action dynamically in pest control in insects.
But this is an example more along the lines of adaption, not an increase in the complexity of the organism itself in the sense we need to observe in order for evolution to be true as you’ve defined it.
If you think this is an argument of populum they you have grossly misunderstood.
Arguing that something is knowledge on the basis that many people accept it is an argumentum ad populum – end of story.

I've already provided you a link where there are a number of scientists, some in the field, who dissent from Darwinism. So, it’s simply incorrect to argue that all scientists agree with evolution.

Yes please. If there are reliably repeated observations of where, let’s say, a fish-like critter gave rise to a man I’d love to see it.
But what we're talking about here is just common scientific knowledge. You should be able to study this on your own if you're truly interested in evolution instead of just supporting the nonsensical creationism objections to it.
If my objections are so nonsensical you should be able to demonstrate that quite easily. I think what’s becoming apparent is the nonsensical claim that evolution (as you’ve defined it) is a fact.
Science has already made the argument. They've done it convincingly and in great detail.
Sure, lot’s of argument have been made. But you implied the argument is sound thus implying it is true. I’d like to see that sound argument if you wish to hold your position that evolution as you’ve defined is true.

Now, if you’d like to restate your claim to something like Darwinian type evolution is an inference which you believe to be true, then we have nothing further to debate. But let's not continue the charade of insisting that Darwinian evolution is an established (or even establishable for that matter) true fact.

Divine Insights example of evolution is a broader generalization of the term. I think you are probably taking it to literally.

Lets use your house example and try and put a perspective on it.

While your house hasn't changed since it was built houses have changed


we have gone from straw huts like this

Image

to making complex houses like this

Image



Lets take your rock example. You are just looking at the rock in a brief slice of its existence. It probably started out as just bits of sediment that over time other bits of sediment compressed against each other and through pressure formed into a singular rock. The rock in your example is more complex than the sediment it started out as.

The tree in your example is evolving life and death are part of that process. Not really much debate there.



I DO disagree with his definition that evolving things get more complex things change over time but this does not mean they have to be more complex. Also it is not a definition for biological evolution.

Yes, houses have changed over time. They have changed solely because there is an intelligent agent guiding the change. I can't think of a single exception. Can you? I’m not sure why you think this is an argument for evolution.
Lets take your rock example. You are just looking at the rock in a brief slice of its existence. It probably started out as just bits of sediment that over time other bits of sediment compressed against each other and through pressure formed into a singular rock. The rock in your example is more complex than the sediment it started out as.
But a rock is no more intrinsically complex than the bits of sediment anymore than 100 hundred mud huts compressed together are more complex than a single mud hut. It’s certainly not more complex in the same way we would say a human is more complex than a bacteria.
The tree in your example is evolving life and death are part of that process. Not really much debate there.
Depends on what you mean by evolve. If you mean the tree is becoming more complex than there is much to debate.
I DO disagree with his definition that evolving things get more complex things change over time but this does not mean they have to be more complex. Also it is not a definition for biological evolution.
Fair enough. But there seems to be a smuggled premise when some evolutionists say "evolution is true." If all that evolutionists meant by “evolution� was merely change, there wouldn’t be the raging debate we see today.

You are being totally unreasonable.

What I claim to have defined was "evolution" as it occurs within the universe via observation. I did not claim to be demanding that all objects must necessarily evolve to become more complex. On the contrary the actually processes of both evolution and erosion are well-known scientifically and both are described sufficiently.

Moreover, erosion is not the opposite of evolution.

The process through which atoms evolved to become minerals within stars is well-known. How rocks are formed is well-known. How rock erode is well-known.

The arguments that you are given are not even rational. On the contrary all you have done is make a completely uninformed personal objection to things that you are clearly either totally ignorant of, or pretending to be in extreme denial of.

These processes are taught in high schools. And they are elaborated on in great detail in colleges.

What you are attempting to argue for is absolute nonsense that doesn't even remotely acknowledge or recognize the human intellectual understanding of these things.

I disagree completely. The evidence is overwhelming. To pretend that it's some sort of vague interpretation is indeed a pretense.

Moreover, even if I were to grant your absurd claim on this matter, the fossil record still shows without question than many species have indeed become extinct. No interpretation required there for sure. In fact, we have even observed species becoming extinct within human history.

So your job (if you want to reject evolution) is to come up with a better explanation. What do you have to offer? Creationism? :-k

A creator God who creates thousands of species only to let them go extinct again almost instantly? Why would a creator bother doing that? Or is he so inept that he's playing trial and error?

Apparently you object to evolution but you don't have a better explanation to offer other than a totally inept bumbling creator. And where is there any evidence for that?

Science isn't concerned with your petty objections. We wouldn't expect to see that huge of a change over the time scales that we can observe live.

Your objections are uneducated and ill-informed.

How are you defining complexity? And how can you say that one of these bacteria are not more complex than another?

That's not my argument.

I'm talking about scientists who are actually making observations and doing experiments and actually trying to prove each other wrong.

So your objection here is totally bogus and without merit.

That's creationism baloney. Those "scientists" have no merit. They have nothing to offer that makes any sense or that can be independently established. Not to mention they have no better theory to offer. In fact, if they offer "Creationism" or "Intelligent Design" as an alternative theory that only proves beyond any shadow of a doubt that they are bogus scientists and they are really just religious people who have nothing productive to offer.

Fine. And I reject your notion of knowledge as well because you have made it crystal clear that you have no knowledge to even offer. All you have been doing in this thread thus far is whining about evolution. What do you have to offer as an alternative theory? :-k

If you have no alternative theory then you have no knowledge to bring to the table.

Intelligent design and creationism have already been ruled to not be legitimate science by the Supreme Court. So neither of those represent credible knowledge. Those are merely faith-based superstitions that have no intellectual merit.

A fish never instantly gave rise to a man directly. Clearly you are making absurd and unrealistic demands that aren't even claimed to be true by evolution.

Then go to college and learn about it. There are many colleges that will be more than happy to educated you on this topic.

Darwinian evolution is a fact of life. Period amen.

It has been well-established and there is no dispute over this in the scientific community at all. The only people who dispute it are religious fanatics who believe in things like creationism and intelligent design as a matter of pure faith with no evidence to back that up at all.

If you hang around with Creationists you'll probably end up thinking like they think. But if you are genuinely interested in truth, then I would suggesting hanging around with real scientists. ;)

That's about all I can tell you.

Colleges will be more than happy to provide you with all the facts you need to know that the creationists are nothing more than religious zealots that have no legs to stand on.

You complain about evolution, but you haven't offered a credible alternative. So until then your complaints are meaningless.

Science can't prove anything, so how to you expect us to prove evolution to you?

Proof is for math, formal logic, and distilled beverages.

Science provides the best explanation. Having said this, evolution is both a theory and a fact. We know it happens.
