A new member of the Aussie Atheist Forum, Freediver, has jumped into the pool and dropped this little gem.
Freediver said..."Evolution is not a scientific theory!
Evolution should not be taught in high school science classes because it is not a scientific theory. It fails the requirement of falsifiability that is the litmus test for judging whether an investigation is scientific.
The modern scientific method is defined in terms of hypotheses, theories and laws. The difference between each is the level of acceptance in the scientific community. What they all have in common is that they must be falsifiable. This means that it must be possible to run an experiment that would prove the theory (or hypothesis or law) wrong, if it were not true."
It is naive to think that falsification is the only thing that makes science, science.
Falsificationism is not abused by antievolutionists invoking it as a rigid standard for rational discourse; rather, it is abused when they use it as a rigid standard for deciding what belongs to the realm of science. The demarcation between science and non-science is a very thorny issue that is not sufficiently addressed by falsificationism.
It is a naive view of falsification to expect that whenever we encounter data that are contrary to what is predicted by the hypothesis being tested, that we must discard the general concept behind that hypothesis. This is an exceedingly important point to understand because, while at face value it seems counterintuitive, it does not violate any rule of logic.
The structure of scientific epistemology acknowledges
1) General Concepts
2) Specific Models and
1)General Concept= Darwinian evolution
2)Specific Model= Continuity of the fossil record and
3)Observation= (for falsification) Discontinuity of the fossil record.
When the predicted observation is not found, then one needs to examine either the Specific Model and/or the General Concept. Often one can reasonably make the equation fit simply by changing the specific model and retaining the general concept. Thus, the prediction of gradual evolution might be substituted with a prediction of punctuated evolution.
Science, therefore, often does not directly test the General Concepts. Rather, it often tests Specific Models and a number of Specific Models can support any General Concept. So, while the General Concept of Darwinian evolution may not be falsifiable, it also is not the direct object of scientific inquiry. The Specific Models of Darwinian evolution are what is tested by science and these are what need to be falsifiable.
Simply put Freediver, evolution as a concept is undeniable (unless you are wearing god goggles) and also unfalsifiable. It is the mechanism of evolution ie. the theory, that is what needs to be testable.
Look past your nose and you will see that there is lots of repeatable experimentation in the field of evolutionary biology here is a start for you.
