Microevolution

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 ›

Today’s ID the Future features three recent Evolution News essays by Lehigh University biology professor and Darwin Devolves author Michael Behe, as read by host Andrew McDiarmid. In the first, nothing shows the feebleness of Darwinism quite so much as breathless stories about new results that turn out to be much ado about nothing. In this case, it’s some recent speculation about the rise of “lactase persistence” in many human adults. Then it’s onto malaria, much beloved of evolutionists, not for its lethality but as a demonstration of evolution in action. But Behe dissects the latest news story on the topic to show that the touted malaria evolution is, once again, malaria gnawing off the proverbial leg to achieve a 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 ›

On this ID the Future Eric Anderson and physician Howard Glicksman further discuss a recent Journal of Anatomy article suggesting possible evolutionary changes in humans: a persistent, prominent median artery in some people’s arms. Journalists have hyped this as evolution in action, but Anderson and Glicksman say there’s little reason to treat this as an evolutionary change, even if it’s real. And they say it’s far from clear how natural selection could select for this as an “adaptation” when its most obvious effect is to contribute to carpal tunnel syndrome and other health problems.

On this ID the Future, Eric Anderson and physician Howard Glicksman discuss a recent article in the Journal of Anatomy suggesting new microevolutionary changes in humans. Researchers say a growing number of adults have a persistent, prominent median artery in their arms, an artery that’s important in the embryonic stage but tends to disappear later on. The study was quickly hyped in the popular press with breathless headlines such as “Evolution arms us with an extra artery.” On the way to separating hype from substance, Anderson and Glicksman dive into the physiology of arteries and embryological development. Their conversation grows out of a post on the subject by Anderson at Evolution News. Oh and by the way, don’t let the 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 we hear the first part of Discovery Institute Education Outreach Associate Daniel Reeves’ talk at the 2020 Dallas Science and Faith Conference. Reeves outlines the meaning of natural selection, and traces its history, starting from Darwin’s early understanding, in the days when cells were viewed as just blobs of protoplasm. Reeves carries the story from there through the neo-Darwinian modern synthesis and into the extended evolutionary synthesis, culminating in a 2016 meeting of the Royal Society on the theory’s continuing — and still unresolved — explanatory deficits.
