“Irreducible Complexity” May Be Part of the Definition of Life

There are many bad counter-arguments to Michael Behe’s famous irreducible complexity conundrum, and (in my opinion) one pretty good one.  Read More ›

Was God a Bacterium? 

We should acknowledge that this theory is, unlike some similar attempts, at least an actual solution: if true, it would explain how complex life evolved. Read More ›
