DNA Proves Existence of a Designer

[Angrboda]

You can address any of the examples of speciation events which have been provided to you..at any time.

Sure can: They could just as easily be examples of adaption. The species is only changing in minor ways, not turning into an entirely different species.

What in your words is the difference between an adaptation and turning into an entirely different species? I guess the crux at the heart of the question is what do you believe determines what a species is such that we can determine whether an organism that has changed is still within the same species, and thus is merely adapting, as opposed to a species that has changed enough to make it no longer a part of the original species. It's said that every species is a transitional organism, and that every organism is a transitional organism, as all organisms are different from their parents, and all organisms are thus in some respects different from their parent species. I'll help the debate along by suggesting that a mutation in the germ line is a necessary condition of a mutation or other event giving rise to a new species. Beyond that, things get murky. What do you consider the minimum change necessary for an organism to display, relative to any of its ancestors, that would be required for an organism to be part of a new species?

(Note that this becomes entangled with common descent. An organism need not be sufficiently different from its parent, but rather from any prior ancestor, because if speciation does not occur, then all ancestors of the organism are necessarily of the same species and can serve as the referent for change. For example, in ring species, immediate descendants of mating couples may indeed be fertile with their parents and others like them. However, if interfertility is the standard, and if they are not interfertile with any given organisms in the ring, and all organisms in the ring are conceded to be related, then speciation by definition has occurred.)
