Problem: Evolution is presented as fact, and not much deep scientific thinking has been presented that would contradict evolution or a gradual development of life.
Darwin himself stated: “If it could be demonstrated that any complex organ existed which could not possibly have been formed by numerous, successive, slight modifications, my theory would absolutely break down.” In Darwin’s Black Box Behe shows that there are complex biochemical systems within cells and between cells that could not have been produced gradually by gradual evolution as proposed by Darwinism.
Behe describes in detail four of these complex systems: a cilium which cells use to swim or move fluid; the blood clotting mechanism; how cells transport materials from one part of a cell to another and how cells defend themselves against intruders. As he presents each system, Behe discusses whether or not each one could have gradually evolved into existence.
Behe presents an extensive review of papers, journals and books on “molecular evolution”. This survey shows that nothing has been published to explain how the aforementioned complex biochemical systems have come into being.
As an added bonus, Behe includes an appendix, which is an introduction to basic biochemistry. This appendix covers topics such as cells and membranes, proteins and structures and how genetic information is expressed and propagated. This section further illustrates the incredible complexity of every single cell.
Behe himself does not strictly support the creationist view in the book. However,this does not detract from the powerful scientific evidence he presents to cast serious doubt on the likelihood of life accidentally coming about through gradual changes in the chemistry of this world.
