I was referring to the lack of observable physical evidence (as in a detailed fossil transition) of a change from one kind to another, which obviously doesn’t exist. This is why I keep referring to your terminology and charts as scientific speculation.
I’m not sure that barriers to reproduction and the inability to reproduce are really the same in the scheme of things (when it comes to variations of kind). And it certainly doesn’t mean macroevolution is taking place. This seems contrary, more like the reduction of genes, rather than say, the addition of two amino acids to the FoxP2 gene that came from ‘out of the blue’ to make us human (example).
Of course, the process is not observable… more speculation.
Actually, the confusion came about when science’s classification system changed the meanings of species and genus so that they no longer equated with the biblical kind and variations. I think we have discussed this previously.
