Well, I love to tell ya, if the fossil record is the "cornerstone" of evolution theory it is every bit as much evidence that the laws of nature have operated consistently throughout history just as God established them.
There is no astronomical evidence (through spectral data) to determine that "laws of nature" were drastically different at any point after at redshift of say 8 or so, which represents an age of the universe of a few million years in the standard model.
Just like they might operate without the hand of a designer. Why introduce something that isn't needed? You'll need to come up with something stronger to inject a designer into the process.
