exaptation

On today’s ID the Future biologist Michael Behe and Philosophy for the People host Pat Flynn conclude their conversation (posted by permission here) about some of the best objections to Behe’s central case for intelligent design. One objection Behe and Flynn tackle in this episode: the idea of evolution overcoming the irreducible-complexity hurdle through co-option. That is, maybe the precursors to what would become one of today’s molecular machines, such as the bacterial flagellum motor, co-opted simpler machines being used for other purposes, allowing evolution to build a bacterial flagellum motor one small step at a time over thousands or millions of generations, even though the completed bacterial flagellum ceases to function at all when just one of its many key parts Read More ›

In today’s ID the Future, intelligent design pioneer Michael Behe continues his conversation with philosophers Pat Flynn and Jim Madden. Here in Part 2 of a three-part series, Behe offers an illustration from language and Madden presses him, noting that meaning detection in language is not parts to whole. A lively exchange ensues and then Behe turns the discussion back to his primary focus, detecting design in molecular biological machines by recognizing the purposeful arrangement of parts. From there the conversation turns to everything from epigenetics, systems biology, and autopoiesis to co-option, mousetraps, tie clips, biologist Kenneth Miller, and the philosophers Aristotle and Thomas Aquinas. For Behe’s newest book, A Mousetrap for Darwin, go here. This discussion is presented here with permission of philosopher Read More ›

On this episode of ID the Future, Andrew McDiarmid interviews biochemist Michael Behe, author of the forthcoming Darwin Devolves: The New Science About DNA That Challenges Evolution (order here) to get his response to a review of the book that appeared in the prestigious journal Science. Behe says the review largely ignores the central point of his book; the reviewers fail to distinguish between claims that evolution built something, and explanations for how it could have built it; and they miss something crucial about lab experiments that engineer examples of evolution.
