I doubt that you can sustain an argument that states evolution is not falsifiable because it most certainly is. For example, take Behe's attempt with irreducible complexity. If we found that certain complex structures could not be derived from simpler antecedents then Evolution would indeed be falsified.

If we found that closely related species were more biochemically separate than more distant related species, evolution would again be falsified.

If we found mammalian fossils in Pre-Cambrian rock then Evolution would be falsified.

Evolution meets the criterion of falsifiability.



Falsifiability as part of the scientific method does not refer to the plausibility of stumbling across contradictory evidence at some undetermined time in the future. Rather, it refers to the ability to design a repeatable experiment that would disprove the theory if it were true. Anywhere, any time, any scientist.

That's right. Any scientist in the world is free to: examine every fossil for relatedness, can test for irreducible complexity, can test the rock strata etc at any time.

Repeatability is not alien to Evolution.

That is not what an experiment is. It also does not help you falsify anything.

Suppose you dug around your entire life and failed to find the falsifying evidence. Would this indicate there is none, or merely that you hadn't stumbled across it yet? For a theory to be considered falsifiable, you have to be able to do an experiment that will falsify it if it is not true - not just a pretend experiment that might falsify it if you are lucky.

Do all falsifying experiments have to be 100% effective? You're wading around in the realms of proof in a domain that doesn't have such a concept.

It depends what you mean by effective. If you mean do they have to disprove a theory, then obviously not. It is the failure to disprove a theory, despite rational attempts to do so, that eventually leads to it's acceptance by the scientific community. This acceptance is not proof.

What do you think an experiment is free diver? Someone mucking around in a lab with test tubes? If so that's a pretty limited and fallacious view. It sounds like the no true Scotsman fallacy.

How is not going to the appropriate strata not an experiment to test whether any fossils of complex animals are where they are not meant to be? How is testing the prediction that a certain transitional form should be found at a particular stratum not an experiment? You would know, of course, this has been done and transitional forms have been found where they were thought to be. It might take time but it's a valid test.

How is not comparing different species biochemically to test relatedness not an experiment? How is not growing generations of bacteria in different mediums to test for mutation( and therefore direct evidence of evolution) not an experiment? How is not breeding colonies of flies under different conditions to see if evolution occurs not an experiment?  

Another interesting test of evolution was the creationist contention that chimpanzees could not be related to humans because they had an extra pair of chromosomes. Evolutionists said that there must be some sort of fusion of this pair into one. Lo and behold geneticists found this to be exactly the case.

The fact is if evolution weren't repeatably testable you wouldn't have Creationists keep throwing up attempts at disconfirming it. Every attempt they have tried has been squarely rebutted.

The belief that Evolution does not meet scientific criteria is false.

Many people seem to misunderstand what an experiment is, which is unfortunate as experimentation is the foundation of the scientific method. The stereotypical experiment involves a lab and test tubes....

Because there is no 'control'.

Science is not just a philosophical debate. How much scientific merit do you think the contribution of these creationsists have?

Science has much better answers than religion.
All religion can say is that:
" The bloke with the long beard did it".
Adults require a better explanation than that.

Creationists offer nothing of value to science other than I suppose an opportunity to bolster science in the public domain- much to their chagrin.

No control, Mr Diver? Really, so how do you think they notice a mutation when they detect one?

I'll now look at your explication of an experiment. However,from your comments thus far, I'd say it's quite narrow.

It seems that the view your promoting here is a narrowed view of the explication you(?) gave via the link. The fact is that the examples I gave straddle both the hard science and soft science approaches. Evolution fulfils the criterion of experiment unless, of course, you're not understanding what you penned.

Hard science-  observations of generations of bacteria and flies under varying conditions. Biochemical analysis of closely related and distantly related species.

Soft science- field studies - rock strata and fossil comparisons from lower strata to higher strata.

Not with a control anyway. Perhaps I should explain what the role of a control is in the context of a scientific experiment.

Real scientific experimentation is where you control one variable, predict the response of the bacteria to that variable, and see what the response actually is. Science is explicitly not just about observing and coming up with theories based on observation, but on rigourously testing those theories. The measure of a good scientist is the ability to design an experiment that puts the theory to the test.

Your definition is flawed. Have you ever heard of multivariable hill climbing techniques? You don't have to hold all variables constant and vary just one. It's commonly used in research.

It  seems Mr Diver that you are turning a blind-eye to what you had penned concerning experiments on the web page you referrred me to.
Evolution and the examples I gave fit neatly within the methodology of hard and soft sciences.

Hard science

Again, let me ask, if you are adamant in using control groups where does comparing an ancestral group of  e.coli with descendant groups of e.coli generated in citric acid to test for mutations fail your requirement? The experiment has been done and a descendent group of e.coli mutated to be able to absorb and assimilate the citric acid- something the ancestral group could not do.

Soft science

You might also be aware that their are certain land locked lakes in Africa inhabited by a particular fridge and as you excavate down throw the layers of the lake's floor you will find a succession ancestral forms of this fish in the fossils. How does this not test evolution?

Same principle. Digging in the ground is not a matter of altering more than one variable at a time.

It doesn't. That is a scientific experiment.

It is a test of sorts, just not a scientific one. There are much more effective ways to test fridges than dumping them on the bottom of a lake.
