How Life Leverages the Laws of Nature to Survive

Left to their own devices, the natural result of physics and chemistry is death, not life. So how are we still breathing? On this ID The Future, host Eric Anderson concludes his conversation with physician Howard Glicksman about some of the remarkable engineering challenges that have to be solved to produce and maintain living organisms such as ourselves. Glicksman is co-author with systems engineer Steve Laufmann of the recent book Your Designed Body, an exploration of the extraordinary system of systems that encompasses thousands of ingenious and interdependent engineering solutions to keep us alive and ticking. In the “just so” stories of the Darwinian narrative, these engineering solutions simply evolved. They emerged and got conserved. Voila! But it takes more than the laws of nature to keep us from dying. In Part 1, Glicksman discussed how two laws of nature - diffusion and osmosis - must be innovated by living systems to avoid cell death. In this episode, Glicksman provides another example: how we regulate the flow of water and blood through our bodies without the excess leakage or shrinkage that can lead to cell death. The protein albumin is crucial. Along with helping to transport minerals and hormones, albumin vitally maintains blood volume by regulating the water flow in and out of the capillaries. How does our liver know how to make albumin, or how much of it to make? Can a gradual Darwinian process be credited with these essential innovations? Or do they bear hallmarks of design? Listen in as Dr. Glicksman explains this remarkable system, just one of many engineering feats our bodies perform every day to keep us alive. Read More ›

Origin of Life’s Purple Unicorn: Protocells

On today’s ID the Future, host Eric Anderson sits down with Rob Stadler, co-author with Change Tan of The Stairway To Life: An Origin-Of-Life Reality Check. The topic of discussion–protocells. Stadler notes that the simplest existing single-celled organisms are far too sophisticated to have emerged through a blind process of prebiotic evolution. He further notes that this is widely acknowledged in the origin-of-life community, but those committed to a purely materialistic origin of the first life have a fallback explanation–protocells. That is, early biological structures far simpler than anything we find today. An intriguing hypothesis, but the problems with it, according to Stadler, are legion. Tune in as Stadler and Anderson walk through several lines of evidence that appear to break against the much sought-after but ever-elusive protocell.
