common descent

In 2009 atheist biologist Richard Dawkins offered a scientific test to decide between Darwinian evolution and intelligent design (ID). The results are in, and as guest Casey Luskin explains on this ID the Future, the evidence has broken strongly in favor of intelligent design. At the time Dawkins presented the test, he was confident that comparative DNA evidence supported Darwin’s tree of life and its idea of universal common ancestry. He made the point in his 2009 book The Greatest Show on Earth and in two interviews. As he put it, “The single most convincing fact or observation you could point to” in favor of Darwinian evolution over against ID “would be the pattern of resemblances that you see when Read More ›

Today’s ID the Future wraps up a debate over evolution and intelligent design between Lehigh University biologist Michael Behe and Benedictine College theologian Michael Ramage. Both Behe and Ramage are Catholic, and they carry on their conversation in the context of Catholic thinking about nature and creation, in particular the work of Thomas Aquinas and contemporary Thomist philosophers. Ramage seeks to integrate his Thomistic/personalist framework with modern evolutionary theory’s commitment to macroevolution and common descent. Behe doesn’t discount the possibility of common descent but lays out a case that any evolution beyond the level of genus (for instance, the separate families containing cats and dogs) cannot be achieved through mindless Darwinian mechanisms and, instead, would require the contributions of a Read More ›

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 Read More ›

On this ID the Future, geologist Casey Luskin discusses biogeography and the problems it poses for the idea of universal common descent. To make it work, evolutionists have to propose, for instance, that old world monkeys rafted across the Atlantic from Africa to South America on a natural raft. Really? That’s some raft. And how did the monkeys not starve to death? Or die of thirst? They couldn’t drink salty ocean water, after all. And talk about a genetic bottleneck! That’s just one of several problems Luskin raises with the idea that all species gradually evolved from a universal common ancestor. In his conversation with host Emily Reeves, he also touches on the problem of convergence, as when two creatures Read More ›

Today’s ID the Future spotlights The Comprehensive Guide to Science and Faith, and specifically, an essay in the new anthology by biologist Jonathan Wells, “Is Darwinism a Theory in Crisis?” As Wells and host Casey Luskin note, the essay title alludes to philosopher of science Thomas Kuhn’s influential 1962 book The Structure of Scientific Revolutions. Kuhn argued there that if one studies the history of scientific revolutions, one finds that when the scientific evidence has begun to turn against a dominant scientific paradigm—when its days are numbered— its adherents do not simply concede defeat. Instead they use all their institutional power to suppress dissent and punish proponents of any competing paradigm. This is the period of crisis, which can last Read More ›

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 ›
