On this ID the Future, Your Designed Body author and physician Howard Glicksman again sits down with host and professor of neurosurgery Michael Egnor to further explore Glicksman’s new book, co-authored with engineer Steve Laufmann. Here Glicksman gives a quick flyover of what they explore in fascinating depth in the book, namely the irreducible complexity of that extraordinary systems of systems that is the human respiratory system. As Glicksman explains, there are individual systems that are irreducibly complex, and these are joined together into a higher-level system of systems that is also irreducibly complex, marked by causal circularities and coherent interdependencies at every turn. Without all of it guided by various highly precise control mechanisms, no life. Darwinian gradualism is Read More ›
On today’s ID the Future, Your Designed Body co-author and physician Howard Glicksman talks with host and neurosurgery professor Michael Egnor about Glicksman’s new book, co-authored with systems engineer Steve Laufmann. Glicksman walks through a series of systems in the human body that are each irreducibly complex, and are each part of larger coherent interdependent systems. As Glicksman puts it, the human body is “irreducible complexity on steroids.” How could blind evolutionary processes, such as neo-Darwinism’s joint mechanism of natural selection working on random genetic mutations, build this bio-engineering marvel? Your Designed Body makes the case that it couldn’t. It’s not even close. What is required instead is foresight, planning, and engineering genius.
On this ID the Future, physician Howard Glicksman and host Eric Anderson dive deeper into the body’s exquisite blood pressure control system, cueing off a new discovery described at Science Daily as uncovering “the location of natural blood-pressure barometers inside our bodies that have eluded scientists for more than 60 years.” According to the primary research paper at Circulation Research, “Renin-expressing cells are essential for survival, perfected throughout evolution to maintain blood pressure (BP) and fluid-electrolyte homeostasis.” How did evolution perfect the system? How did it originate the system? The paper never says. The mention of evolution appears to be little more than a de rigueur genuflection before the reigning paradigm of blind evolution. What is bearing actual fruit, according to Glicksman Read More ›
On this ID the Future, physician and Evolution News writer Howard Glicksman discusses an exciting new discovery by researchers at the University of Virginia School of Medicine, described at Science Daily as uncovering “the location of natural blood-pressure barometers inside our bodies that have eluded scientists for more than 60 years.” As the article reports, “The existence of a pressure sensor inside renin cells was first proposed back in 1957. It made sense: The cells had to know when to release renin, a hormone that helps regulate blood pressure. But even though scientists suspected this cellular barometer had to exist, they couldn’t tell what it was and whether it was located in renin cells or surrounding cells.” Dr. Glicksman and 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 ›
Physician Howard Glicksman talks with host Ray Bohlin about the amazing control systems involved in something we’re all familiar with: blood pressure. It’s a system requiring adjustment at every point along the way, from blood volume to blood pumping velocity to pressure out in the blood vessels. And it has to be able to act fast in order to keep us alive — which leads to some hard questions for Mr. Darwin.
On this episode of ID the Future, to celebrate Michael Denton’s newest book, The Wonder of Water, we bring you a conversation between Ray Bohlin and Howard Glicksman on the body’s wondrous control systems for using water. Dr. Glicksman is a medical doctor and author of an extended series of posts at Evolution News & Science Today, “The Designed Body.”
On this episode of ID the Future, Ray Bohlin interviews physician Howard Glicksman about hemoglobin and the body’s need to have enough of it to transport sufficient oxygen to the tissues. Finely-tuned and exquisitely engineered, this system gave our ancestors enough oxygen to not only stay alive but thrive in the face of hostile challenges. Dr. Glicksman is author of an extended series of posts at Evolution News & Science Today, “The Designed Body.”
