On today’s ID the Future, philosopher of biology Paul Nelson discusses his chapter in a recent Harvest House anthology edited by host Casey Luskin, The Comprehensive Guide to Science and Faith. Nelson says the theory of universal common descent, a key component of modern evolutionary theory, has generated multiple predictions that have failed. The prediction he discusses here is that there would turn out to be a single universal genetic code, since that’s what we should expect if all life on earth is descended from the last universal common ancestor (LUCA). Findings over the past three decades have  proven that prediction spectacularly wrong. How does the theory of universal common descent shrug off this contrary empirical finding? The trick for LUCA in this and similar cases is to shift blame for failure to an ancillary theory. It’s a clever move, says Nelson, but it comes at a cost.

Paul A. Nelson is currently a Senior Fellow of the Discovery Institute and Adjunct Professor in the Master of Arts Program in Science & Religion at Biola University. He is a philosopher of biology who has been involved in the intelligent design debate internationally for three decades. His grandfather, Byron C. Nelson (1893-1972), a theologian and author, was an influential mid-20th century dissenter from Darwinian evolution. After Paul received his B.A. in philosophy with a minor in evolutionary biology from the University of Pittsburgh, he entered the University of Chicago, where he received his Ph.D. (1998) in the philosophy of biology and evolutionary theory.
