Behe points out that the Darwinian theory of evolution through natural selection is invalid because the existence of molecular
Behe, on the other hand, uses an example of cilia along the lining of our lungs to explain his property of irreducible complexity. First there’s the question of why the cilia beat sideways which can be understood by looking at their structure. Cilia are made of two microtubules which are kept apart by dynein, however nexin proteins work to hold them together and help in the sliding-fiber-mechanism that causes the sideways motion. One doesn’t get the function of the cilium until the parts are all intact. This example proves that a cilium is in fact a molecular machine that exhibits specification, because the interaction of parts is a design and not natural selection.
III. OBJECTION AND RESPONSE
Behe asks, "Are there more plausible explanations for the complexity of life?" My answer to his question is yes, in fact there are more plausible explanations for the complexity of life; natural selection is a possible explanation for the complexity of life. I believe his argument against the Darwinian theory of natural selection is wrong because irreducible complexity doesn't take into account that complex systems could have evolved over time. When Behe argues that "an imaginative person might see things that other people miss. Or he might see things that are not there," he fails to consider the…
