common descent

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?

Today’s ID the Future spotlights a new book, The Comprehensive Guide to Science and Faith: Exploring the Ultimate Questions about Life and the Cosmos, and specifically a chapter by biologist Jonathan Wells titled “What are the Top Scientific Problems with Evolution?” Wells is the guest, and the host is geologist and Center for Science and Culture associate director Casey Luskin, who co-edited the anthology from Harvest House Publishers. In this episode the first problem that Wells highlights concerns homology and convergence. A second problem involves fossils. Darwin anticipated “innumerable transitions” in the fossil record, but such a rainbow of transitional forms has never been found. Not even close. Another problem, molecular phylogenies. Another: the lack of observational evidence that natural Read More ›

On this episode of ID the Future, biologist and professor Robert Waltzer talks with host Andrew McDiarmid about Waltzer’s chapter in the new Discovery Institute Press volume Evolution and Intelligent Design in a Nutshell. Waltzer’s chapter covers some key terms in the evolution/ID conversation that are often misunderstood or misused. These include the word “evolution” itself, “change over time,” “common descent,” and “natural selection.” He offers quick definitions and explains some of the confusion surrounding them. Waltzer also describes an encouraging success story of his about fostering open dialogue and exploration of the evidence for design in nature.

On this episode of ID the Future, paleontologist Günter Bechly speaks again with host Andrew McDiarmid about the growing case against Darwinian gradualism. Bechly points out two more cases where fossil discoveries refuted Darwin’s prediction of gradualism in species transitions. In one of the classic showcases for such alleged transitions, between two species of deep-sea protists called foraminifera, more recent research showed their speciation to be abrupt and not an ancestor-descendent sequence. And fossil freshwater snails from Germany, once viewed as another textbook example of gradual speciation, were discovered not to be separate species at all. Is there a paradigm change coming in evolutionary studies? Nothing fits the data better than intelligent design.

On this episode of ID the Future, paleontologist Günter Bechly and host Andrew McDiarmid discuss Bechly’s article “Ape-Man Waves Goodbye to Darwinian Gradualism.” Bechly touches on the oldest australopithecine fossil skull ever found, from 3.8 million years ago. The researchers behind the find are confident of its age but puzzled because the discovery undercuts one of the best examples of alleged gradual transition between two hominid species, and it also doesn’t fit well with common theories of phylogenetic relationship. The evidence poses a significant problem for the Darwinian mechanistic paradigm, but can be readily explained with an intelligent design approach.

Today’s episode of ID the Future comes from a Berkeley, California symposium honoring the recently deceased Phillip Johnson. Biologist Jonathan Wells recalls how he met Johnson and the huge influence he had on Wells’ own research and writing. Then philosopher of biology Paul Nelson reminisces on Johnson’s keen intellect, his eye for hidden assumptions, his awareness that “we are not of our own devising,” and on the mountain range of new knowledge opening up to us in biology, one that scientists knew little about even 30 years ago and that Nelson says points strongly away from Darwin’s idea of common descent.

On this episode of ID the Future, biologist Ann Gauger talks with host Andrew McDiarmid about new research challenging the common claim that the field of population genetics rules out a single-couple human origin. She and Stockholm University statistical mathematician Ola Hössjer have just published a paper in the journal BIO-Complexity modeling the scenario using a newly developed computer algorithm. The results, Gauger says, show that the genetic data does not rule out Adam and Eve.

On this episode of ID the Future, Dr. Cornelius Hunter, author of Science’s Blind Spot: The Unseen Religion of Scientific Naturalism, talks about new findings on so-called “junk” DNA. Evolutionary theory predicts lots of such “Darwinian detritus” that does nothing for organisms. That prediction keeps coming up false. “Satellite DNA” was one form of DNA thought to be junk, and left on the back burner by researchers. But now it’s been found to be both crucial — for the fertility of male fruit flies — and species-specific. Evolutionary theory expected none of this, though it gamely accommodate it, Hunter explains. How? By moving the goalposts.
