Barbarian observes:
Yep. That’s what macroevolution is. Microevolution is variation within a species. Macroevolution is the evolution of new taxa.
Yep. That’s what it means. If you don’t want to use terms as scientists do, then you’ll have a very difficult time talking about science.
Barbarian observes:
Yep. Polyploidy is an example of very rapid macroevolution.
Of course it is. Remember, macroevolution means reproductive isolation from the older population.
It is just extra sets of the parents’ genetic information.
Gene duplication is always an increase in information. Would you like to see the numbers?
Barbarian observes:
Reproductive isolation is macroevolution.
No,it isn’t. Reproductive isolation never leads anything more than speciation within the family.
Even “scientific creationists” admit that new families evolve. They draw the line there, though. But they can’t show that there’s any barrier beyond that level. And as the Pope says, the fact that all organisms are genetically related makes common descent virtually certain.
Barbarian observes:
When two populations no longer freely interbreed, they will increasingly diverge, and eventually be unable to interbreed.
Unable to interbreed is one thing,total genetic isolation is another.
Divergence between two populations never leads to total incompatibility.
O. lamarckania and O. gigas can no longer reproduce at all. Reality trumps anyone’s beliefs.
(arguments that new species of flies are still flies)
Barbarian observes:
Whether they are humans or chimpanzees, they are still hominoids.
Hominoids that are totally incapable of interbreeding and never were capable of interbreeding. No common descent.
That’s been verified in a very interesting way. You see, humans have 46 chromosomes and other apes have 48. This was sort of a problem for common descent. Scientists therefore theorized that the line that led to humans must have had a chromosome fusion in which two chromosomes fused together (such fusions have been observed). When it became possible to analyze chromosomes, it was then found that the #2 human chromosome is almost exactly like two chimpanzee chromosomes, right down to the remnants of telomeres and a no-longer-functional centromere precisely where it would be if there was a fusion. That nails it.
Of course we do have others, like the drosophila population noted by Dobzhanski to have evolved into two reproductively isolated species.
There is still genetic compatibility between the flies.
No. In fact, they are totally isolated now, since hybridization produces sterile individuals, much as hybridization between horses and donkey’s produce sterile mules.
Barbarian observes:
Most speciation is gradual over thousands of years. The apple/hawthorn flies are just an example of more rapid speciation.
Rapid speciation or no,the flies are still just flies,so there is no macro-evolution there.
And chimps and humans are still primates. You see, flies and primates are the same level of taxa. So it’s a rather large amount of macroevolution.
Barbarian observes:
You’ve conflated ontological naturalism with methodological naturalism.
No,I’m using a dictionary definition.
Maybe you need a new dictionary:
**Many modern philosophers of science use the terms methodological naturalism or scientific naturalism to refer to the methodological assumption that observable effects in nature are best explainable only by natural causes. In other words, methodological naturalism is the view that the scientific method (hypothesize, predict, test, and repeat) is the only effective way to investigate reality. Any method of inquiry or investigation or any procedure for gaining knowledge that limits itself to natural, physical, and material approaches and explanations can be described as naturalistic.
Methodological naturalism can be contrasted with the ontological naturalism or metaphysical naturalism, which refers to the metaphysical belief that the natural world (including the universe) is all that exists and, therefore, nothing supernatural exists.**

You can get a more detailed and rigorous explanation here:
plato.stanford.edu/entries/naturalism/
There is no essential difference.
Ontological naturalism says that nature is all there is. Methodological naturalism is a system that is unable to say whether or not nature is all there is.
If you don’t see a huge difference between these two, I believe we’ve found the source of your difficulties.
Barbarian obeserves:
No, Einstein was a deist, who professed belief in the God of Spinoza.
Einstein advocted a cosmic religiosity in his book “Mein Weltbild”. Spinoza was definitely a pantheist.
Let’s take a look. Einstein, when asked if he was a Spinozaist:
**I can’t answer with a simple yes or no. I’m not an atheist and I don’t think I can call myself a pantheist. We are in the position of a little child entering a huge library filled with books in many different languages. The child knows someone must have written those books. It does not know how. The child dimly suspects a mysterious order in the arrangement of the books but doesn’t know what it is. That, it seems to me, is the attitude of even the most intelligent human being toward God. We see a universe marvellously arranged and obeying certain laws, but only dimly understand these laws. Our limited minds cannot grasp the mysterious force that moves the constellations. I am fascinated by Spinoza’s pantheism, but admire even more his contributions to modern thought because he is the first philosopher to deal with the soul and the body as one, not two separate things. **
Letter 1944
Barbarian observes:
The ICR, for example, did what you did; they just redefined “macroevolution” to exclude any sort of evolution that they felt they couldn’t deny.
I didn’t redefine macro-evolution,but you try to.
Let’s take a look…
**Speciation and Macroevolution
19 and 22 March, 1999
Recall from our discussion of microevolution that no population can satisfy all five conditions of genetic (Hardy-Weinberg) equilibrium. This simply means that all populations are evolving - changing genetic makeup over time. As long as two populations are able to exchange genetic information (interbreed), they will maintain similar genetic characteristics. If these two populations lose the ability to interbreed, perhaps because of geographic isolation, then their genetic makeup continues to change over time, but now the two populations are free to change in different ways. If the isolation persists for a long enough time, then the two populations may become different enough to become separate species.
Mayr’s definition of species (page 240) focuses on the element of reproductive isolation - the inability of individuals from separate species to reproduce. This isolation may be prezygotic (coming into play before fertilization) in one of five basic ways: temporal (incompatible reproductive schedules), ecological (two species that are best suited for differing microenvironments), behavioral (incompatible mating rituals) or mechanical (incompatible reproductive organs), or gametic (incompatible sperm and eggs). Postzygotic isolation refers to the inability of a zygote resulting from cross-species fertilization to develop into a viable organism. Note that viable organisms must be able to reproduce - mules are an example of postzygotic isolation even though they are able to successfully complete development.**
