Have to wonder if there is any point in these threads. On the one hand, many things seem irreducibly complex if you don't understand them, and the world to me seems to be full of transitional species. Mudskippers for instance seem more amphibian than do some amphibians, whereas hagfish seem to be logical ancestors of modern bony fishes and platypuses are just weird. On the other hand, macro evolution from a single cell and abiogenesis have severe problems which may or may not ever be solved. In the end, Intelligent Design is either a matter of faith or a matter of statistics, and with the latter, the only guideline we have is our own physical universe. Attempting to prove that something is statistically impossible when the only thing from which to formulate the odds of its occurrence is from the thing itself seems - odd. Odd, and also incredibly difficult to do properly. How many of us could honestly formulate the odds of a new hybrid species such as the silvery salamander arising, much less the odds of it becoming, say, warm-blooded or feathered? I'm guessing none. For that matter, how many of us can actually conceive of new phyla arising, much less calculating the statistical likelihood? Let's just say that evolution into kingdom and phylum seems to us to be statistically improbable without making any absolute claims.
Best to just accept and use evolution within its own constraints and keep Intelligent Design as a matter of faith - and perhaps to occasionally annoy those who believe their own faith makes them mentally superior.
