Speciation Model Support

A team of ecologists and biologists has developed additional supporting field evidence for the Reasons To Believe model for speciation and extinction outlined in The Genesis Question ( This biblical model posits that while extinction rates have remained high and attributable to natural causes, speciation rates (introduction of new species) have dropped to virtually zero since God began His rest after He created human beings. Until this recent research, supporting field evidence was essentially limited to birds, large animals, and bacteria. The new studies broaden the supporting field evidence to cover virtually the entire animal kingdom. A summary quote from the most recent paper states, “Extinction, however, is generally a nonrandom process with risk determined by life-history traits such as rarity, body size, and sensitivity to environmental stressors like pollution.” Such data challenges evolutionary models but vindicates the Scriptures, which describe God’s creative activity in six epochs, followed by a period of rest.

In 1999, I left my position in R&D at a Fortune 500 company to join Reasons to Believe because I felt the most important thing I could do as a scientist is to communicate to skeptics and believers alike the powerful scientific evidence—evidence that is being uncovered day after day—for God’s existence and the reliability of Scripture.
