Responding to Criticisms of Irreducible Complexity of the Bacterial Flagellum from the Australian Broadcasting Network

Time flies. Published in 1996, Michael Behe's book Darwin's Black Box represented a major development in the modern articulation of the scientific argument for intelligent design. Critics continue to make the same arguments, which still fall flat for the identical reasons they did years ago. We've documented this repeatedly. Yet they keep coming at us. Read More ›

Darwin’s Black Box Celebrates New 10th Anniversary Edition

Seattle — Ten years ago, biochemist Michael Behe helped to launch the modern intelligent design movement. when he outlined the theory of irreducible complexity in his book Darwin’s Black Box: The Biochemical Challenge to Evolution, which dared to question the basic tenets of Darwinism.   Arguing that unintelligent accounts failed to explain the development of irreducibly complex systems such as blood clotting, the Read More ›

The Fittest Theory

Because we are the country’s second-largest purchaser of textbooks, the continuing debate between Darwinists and proponents of intelligent design theory (IDT) has more than academic interest. The basic issue is this: Either the existence of intelligent humanity and the sheer complexity of living organisms can be accounted for by natural causes, or they point to an intelligent designer independent of Read More ›

Comments on Ken Miller’s Reply to My Essays

Kenneth Miller, Brown University Professor of Biology and author of Finding Darwin's God, has posted a response to my essays. I think it should be plain to most open-minded readers that he is struggling to fend off examples that weigh heavily against Darwinism. I do, however, want to make a few additional comments, in just two areas, to keep the issues in focus. Read More ›

Darwin’s Black Box: A Review by Ray Bohlin

What do mouse traps, molecular biology, blood clotting, Rube Goldberg machines, and irreducible complexity have to do with each other? At first glance they seem to have little if anything to do with each other. However, they are all part of a recent book by Free Press titled, Darwin’s Black Box: The Biochemical Challenge to Evolution by Michael Behe. Michael Behe is Read More ›

In Defense of the Irreducibility of the Blood Clotting Cascade

Darwin's Black Box: The Biochemical Challenge to Evolution I devoted a chapter to the mechanism of blood clotting, arguing that it is irreducibly complex and therefore a big problem for Darwinian evolution. Since my book came out, as far as I am aware there have been no papers published in the scientific literature giving a detailed scenario or experiments to show how natural selection could have built the system. However three scientists publishing outside science journals have attempted to respond. Read More ›

“A True Acid Test”

In this essay I reply to what I consider to be the most important claim made by any critic of intelligent design: that direct experimental evidence has shown that evolution can indeed generate irreducibly complex biochemical systems. As I will show below, the claim is false. Read More ›

A Mousetrap Defended

In Darwin's Black Box: The Biochemical Challenge to Evolution I coined the term "irreducible complexity" in order to point out an apparent problem for the Darwinian evolution of some biochemical and cellular systems. In brief, an irreducibly complex system is one that needs several well-matched parts, all working together, to perform its function. Read More ›

Irreducible Complexity and the Evolutionary Literature

Although several persons have cited numerous references from the scientific literature purporting to show that the problem of irreducible complexity I pointed out in Darwin's Black Box is being seriously addressed, the references show no such thing. Read More ›
