"Adaption! Adaption! Adaption!" Er, one of the mechanisms of evolution is descent with modification, examples of which I gave you. Screaming "adaption" is not really much of an argument. "We don't see polar bears turn into cats." An ridiculous example, and we might see genetically isolated populations of polar bears become a new species over time, as a population of their ancestors (Brown Bears) did to become Polar Bears. "We see plenty of microevolution, but I have yet to see any macroevolution--one species turning into another." If you can see microevolution then you are actually watching evolution. You'd have to stay around a mighty long time to watch one species turn into another, although we can see that happening of course (see examples given earlier).
