On this episode of ID the Future, CSC's Casey Luskin interviews Dr. Geoffrey Simmons, author of the book Billions of Missing Links. In the book Simmons shows that as modern science has progressed from the visible to the invisible (microscopic, submicroscopic, genetic, biochemical and genetic) the numbers of missing links have skyrocketed. Every "link" discovered brings many more questions (missing links) than answers. Listen to hear more about science’s missing links, and click here to visit Simmons’ Amazon blog on the subject.
