Not at all. Anyone that merely accepts the validity of a paternity test must also accept what I've stipulated as an observable.
Genetics is the new way to go to figure out missing links and common ancestors. But, again, "observable" proof it is not. My point is that it is not "observable" in the sense that these fossils can be observed through experiment to be able to create a new species.
Again, one does not have to be present at the time and place of an event in order to observe it.
And please, desist your use of the word "proof." Proof is for mathematics and alcohol. We're talking about science.
Look, my point is a semantical one. I agree that all of these things are evidence, but they are not experimentally observable from one species to the other. I have already pointed out plants (mustard seed - species variations that we actually eat) where it has been observed, but to use fossils as "observable" science is not true and will only lead to someone with less of a caliber to jump on that mistake and invalidate all other evidence.
But you are wrong. Fossils are a means to observe many things, most readily the morphological similarities to other species and their relative position in the strata of the geological column. Fossils
ARE "observable science." Certainly it is conceivable that the discovery of a certain fossil could falsify a significant amount of current theory. That would awfully difficult if they weren't observable.
Granted, maybe my interpretaion of observable is strict, but science is strict in the way it is conducted.
I would agree that science is rigorous with it's definitions, but your "strictness" is unreasonable and indicative of a shortcoming in understanding.
If you are going to state whether genetic tests like Southern blot is used and is observable, then you must show that. It is observable and a good use of science, but it is only observable becuase of actual experiments that show speciation and the close tie between it and genetics (i.e. - mustard seed - other types of vegetation). You skipped this and went straight to saying that it is observable just because. That leaves a hole in your argument which any fundie will jump on to.
As for fossil evidence, it is not observable in the sense of experimentation. That is my point. Strata and the relative age of different strata is directly observable because it can be experimented by using half-lives of radiological elements. Fossils and their close ties cannot be directly experimentally to be tied. If I was to use phenotypic relations as a means to show evolution, I could point out the duck and platypus as being directly related (reptilian/avian vs. mammalian). Granted, this is what was used to figure out clades before genetics, but again it could not be directly observed through experiment. That is why "missing link" arguments were so prevalent before genetic testing came into the picture. That is my point. It is not "observable" in the sense of science, but it can be used as evidence when an experiment is done that proves it is directly linked to the experiment. Now it is widely accepted that fossils show a progression because evolution is a scientific theory that is widely accepted. You can use fossils as evidence of evolution, but again "observable" in the sense of scientific experimentation it is not.
Also, Geo minor here, so yes I love fossils and sed rocks. And yes, Geology is a science. Again a semantics thing. You can observe the progression of fossils by strata and come to the conclusion that there is a progression (evolution), but is this "observable" through experimentation by fossils? No. Is the same thing "observable" through life currently right now through experimentation? Yes, yes it is. That is why no real dispute between fossil evidence and linking is made, because observable experiments of actual organisms have been shown.
