So if you are shown evidence that it can be observed and can be tested and that you can repeat experiments, would you change your mind?

Unfortunately, the link you provided did NOT give evidence of the kind of evolution that RaisedCatholic was talking about. He clearly defined evolution as a change “from a less complex lifeform into a more complex lifeform.” That tells me that he was talking of
macroevolution, for which the link you provided did not produce evidence.
Undoubtedly there is evidence for
microevolution. For example, one of the articles in the links you provided give evidence of fish developing resistance to PCB (Polychlorinated Biphenyls). But that is microevolution. I think that what RaisedCatholic needs to see is evidence that shows not merely changes in an organism’s biochemistry, but one that shows large morphological mutations that are not harmful to the organism and which, therefore, can be favored by natural selection. Your link did NOT show that kind of evidence.
The link you provided tried to defend the use of evidences that support microevolution as evidence also for macroevolution, as if it is a form of “extrapolation.” However, we need to distinguish between the extrapolation of data practiced in some branches of science (such as Astronomy) from mere
speculation. Good extrapolation always has valid small-scale experimental data that can be extended mathematically in a large-scale phenomenon. For example, from the light emitted by the sun we are able to determine the temperature of its corona. But microevolution does not provide that kind of experimental basis, because no one has shown mathematically how random mutations could lead to the
systematic and
simultaneous mutations required by macroevolution.
If evolution is defined simply as
any change in the genetic makeup of an individual over time, then yes, it is a fact. However, if evolution is defined as the development from a less complex lifeform to a more complex one, then that has NO evidence and remains to be proved.
