Irreducible Complexity

Michael Behe, a biochemist currently teaching at Lehigh University, coined a term for describing the design phenomenon inherent in molecular machines such as the bacterial flagellar motor -- "Irreducible Complexity" -- "a single system composed of several well-matched, interacting parts that contribute to the basic function, wherein the removal of any one of the parts causes the system to effectively cease functioning." (1)  

Like a mechanical motor, each part in the flagellar motor is absolutely necessary for the whole to function. Therefore, I couldn't logically deduce any naturalistic, gradual, evolutionary explanation for the existence of a bacterial flagellum. Besides, no one would expect an outboard motor, whether mechanical or biological, to be the product of a chance assemblage of parts. Outboard motors are designed and engineered!




Of course, I just picked one example. The bacterial flagellum is only one among many thousands of intricate, well-designed, molecular machines. Furthermore, take these same principles of design and "irreducible complexity" and apply them to marvels such as the human eye, ear, heart, lungs and brain. Seriously, how can we logically explain the gradual and random development of these complex systems?

What about the human heart? It's a miraculously efficient and durable hydraulic pump that no engineer could dream of producing…

What about the human brain? It's a legitimate computer system, 1,000 times faster than a Cray supercomputer and with more connections than all the computers, phone systems and electronic appliances on the entire planet...(2)  

Darwin himself made the statement…

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. (3)  

Mystery

In 1859, Charles Darwin published, On the Origin of Species . In it, he argued that all of life on earth was the product of undirected natural processes. Time, chance, and natural selection. Since Darwin, biologists have relied on such processes to account for the origin of living things. Yet today, this approach is being challenged as never before. "Unlocking the Mystery of Life" is the story of top-notch, contemporary scientists who are advancing a powerful idea -- "the theory of intelligent design." Using state-of-the-art computer animation, "Unlocking the Mystery of Life" transports you into the interior of the living cell to explore systems and machines that bear the unmistakable hallmarks of design. Discover the intricacy of a microscopic bacterial rotary motor, which spins at 100,000 rpm. Within the nucleus explore the wonder of DNA, a thread-like molecule that stores instructions to build the essential components of every living organism. It is part of a biological information processing system more complex and more powerful than any computer network. This compelling documentary examines an idea with the power to revolutionize our understanding of life... and to unlock the mystery of its origin.
