Hitting the Brakes on ‘Rapid Evolution’

On this episode of ID The Future, host Eric Anderson concludes his Why It Matters interview with microbiologist Dr. Scott Minnich. In Part 2, Dr. Minnich critiques Lenski's famous Long Term Evolutionary Experiments. Through experiments of his own, Minnich has shown how the practical results of Lenski's project on E. coli are easily repeatable under different conditions, and how some key changes to E. coli are even reversible, both of which speak more to an organism's pre-existing capabilities than to a Darwinian explanation. This is the conclusion to a two-part interview. Read More ›

Evidence Keeps Rolling In

Several new papers have appeared that reinforce key points of my recent book, Darwin Devolves. (Hat tip to Paul Nelson.) The first one — “Quantifying the pathways to life using assembly spaces” — is from a group of theoreticians at Arizona State and the University of Glasgow. (The work was discussed by one of the authors, Sara Imari Walker, at a Read More ›

Can the Theory of Evolution be Simulated through Lab Experiments?

Can the Theory of Evolution be Simulated through Lab Experiments?

Michigan State University biologist Richard Lenski tests evolution and random mutations acting on natural selection to determine what evolution can do. He has experimented with bacteria to see what new functions can evolve just through random mutations acting on natural selection. Biologist Michael Behe has found that there are severe limitations to getting the coordinated mutations that natural selection needs Read More ›
