The Eye: the product of an evolutionary process

From today’s fascinating Pharyngula article, The eye as a contingent, diverse, complex product of evolutionary processes:

… the clumsy organization of the eye clearly indicates that it is the product of an evolutionary process rather than of any kind of intelligent design.

…

What we find in molecular biology is flexibility and modularity, attributes that lend themselves well to combinatorial changes that can easily increase complexity—a complexity that is a hallmark of unguided evolutionary change, not design.
