Bayesian Probability and Intelligent Design: A Beginner’s Guide

If the phrase "Bayesian calculus" makes you run for the hills, you're not alone! Bayesian logic can sound intimidating at first, but if you give it a little time, you'll understand how useful it can be to evaluate the evidence for design in the natural world. On this ID The Future, Dr. Jonathan McLatchie gives us a beginner's guide to Bayesian thinking and teaches us how it can be used to build a strong cumulative case for intelligent design, as well as how we can use it in our everyday lives.

Minimal Replication Fidelity: Another Problem for the RNA World Hypothesis

The RNA world is proposed by some to explain how early life began before DNA. But is RNA capable of maintaining a life-friendly self-replication rate? On this ID The Future, host Andrew McDiarmid welcomes back Dr. Jonathan McLatchie to discuss another headache for the RNA world scenario. Before a trial and error process like natural selection can even get started, self-replicating molecules must have a minimal accuracy rate to copy genetic material effectively. The required fidelity rate is estimated to be 2%. Any error rate higher than that results in error catastrophe for organisms. The average error rate in RNA copying is estimated to be around 17%, vastly higher than the estimated maximum error threshold for survival. McLatchie explains the implications of this for chemical evolutionary theories like the RNA world hypothesis. He also explains how a Bayesian approach to this evidence can provide us with the likeliest explanation for the origin of biological life. "The sorts of features that we observe in life are not particularly surprising if we suppose that a mind is involved," says McLatchie. But things like minimal self-replication fidelity are wildly surprising on a naturalistic hypothesis.

The Engineering Prowess of the Blood Clotting Cascade

The vertebrate blood coagulation system is a delicately regulated marvel that helps maintain the integrity of the circulatory system. Over 20 years ago, Michael Behe argued it was an example of an irreducibly complex system. Does Behe's claim still hold up today? On this ID The Future, host Andrew McDiarmid speaks with fellow Scotsman Dr. Jonathan McLatchie about his new article series examining recent claims that an evolutionary pathway has been identified for this incredible process. McLatchie is a fellow and resident biologist at the Discovery Institute’s Center for Science & Culture. He holds a Bachelor’s degree in Forensic Biology, a Masters degree in Evolutionary Biology, a second Master’s degree in Medical and Molecular Bioscience, and a PhD in Evolutionary Biology. In their conversation, McLatchie describes how the blood clotting cascade works and why it poses a challenge for evolutionary theory. "Evolution doesn't perform particularly well when you need to make multiple co-dependent mutations," he says. McLatchie explains just how delicately regulated the blood coagulation system is and defends Behe's argument for the cascade, saying it exhibits irreducible complexity in spades. McLatchie also critiques recent proposals by the late biochemist Dr. Russel Doolittle, who claims to show a step-by-step evolution of vertebrate blood coagulation. McLatchie notes that Doolittle helps himself to irreducibly complex components as he attempts to explain its origin, inadvertently helping to confirm Behe's arguments in the process.
