Evolutionary biologist Richard Lenski hopes to demonstrate Darwinian evolution in action. But one humble scientist from Northern Idaho says not so fast! On this classic episode of ID The Future from the archive, host Eric Anderson concludes a conversation 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. "Overall, [Lenski's] E. coli haven't generated anything new," observes Minnich. "They're getting rid of stuff they don't need...they have hyper mutational rates...but in the long run, that's not an advantage, because you're just going to acquire too many mutations, and that's the road to extinction."
