An Evolutionary Boundary was Jonathan Whitcomb's entry into active origin-investigations in 2002. Applying natural selection, his mathematical simulations (microorganism populations) demonstrated enormous problems for macro-evolution. The purpose of the study was not to directly disprove the General Theory of Evolution but to determine the probability of one major macro-evolutionary step; but that one step proved practically impossible to obtain: an unexpected direct disproof of the General Theory of Evolution.

Living-pterosaur investigations intrigued Whitcomb, as he watched video footage of natives of Papua New Guinea (the islanders simply told interviewers about what they had seen flying around). As a forensic videographer, Whitcomb recognized the credibility of the eyewitnesses. In 2004, he traveled alone to Papua New Guinea, eventually arriving on Umboi Island, west of New Britain Island. Although he failed to see any of the creatures, he interviewed many native eyewitnesses of the giant featherless "ropen." Whitcomb returned to the United States convinced that Rhamphorhynchoid pterosaurs live in Papua New Guinea. He published the first edition of his book Searching for Ropens, in 2006 (the second edition, in 2007).

While writing his book on living pterosaurs, Whitcomb searched deeper into axioms of the Western academic traditions that greatly hindered living-pterosaur investigations. A summary of some of his findings are included in this site: Science & Origins.
