An interesting (though slightly old) video here. The fossil record doesn't appear to be gradual gradation of change and development over time other than the body size.
Aside from the Creationist they seem to be credible scientists making these observations. Also could some form of Lamarckian evolution on the genetic level be viable? That seems to be in vogue thing atm and is briefly covered in the video.
