Responding to your specific question, I'm not familiar with Mr. Byers or 'Preservation' magazine, which I assume is a scientific and not a religious publication. What he probably means is that zoological evoltution in evident in anatomy, and one can program computer simulations beginning with the simplest animals and going right up to man, everything falling neatly into place. (I think this is called 'morphing'). That would enable a good guess to be made with regard to missing portions of discovered fossils. Not having seen the article, that's the best I can do. The important thing is that science marches on, constantly being updated, while superstition and ignorance remain the same always.
