Good post, troutman--###.
It's a metaphor that's mostly convenient for critics of evolutionary theory--but it has never held a lot of water, even when it could be plausibly argued that a large part of the fossil record is missing. The fossil record is necessarily incomplete--but its incompleteness doesn't invalidate an attempt to explain the data that currently exist. Evolutionary theory explains those data--creation theory, including so-called "intelligent design," doesn't even try.
