On today’s ID the Future, distinguished British physician and author David Galloway explains why he’s convinced that the human fetal circulatory system is irreducibly complex and therefore beyond the reach of blind gradualistic evolution to have built. In his conversation with host and fellow physician Geoffrey Simmons, Galloway also mentions some molecular machines that he’s convinced are irreducibly complex and shout intelligent design. The occasion for the conversation is Galloway’s new book, Design Dissected.
