"Behe addresses two primary categories of structural obstacles to Darwinian evolution: irreducible complexity and devolutionary processes, which fundamentally resist the mechanism of random mutation and natural selection.
The first structural obstacle rests on the reality that modern biology has revealed the cell to be made of machines, complex systems within the cell that cannot originate in the gradual fashion upon which Darwinism insists.
A second, more recently discovered structural obstacle arises from scientists’ ability in the last 20 years to track molecular changes (mutations in DNA) over time and generations. The data shows that the Darwinian process often helps organisms adapt, but it does so overwhelmingly by breaking things that already existed in the organism’s genome. A process that degrades aboriginal design might bring about limited change over time, but it doesn’t have the power to create new forms.
Behe says Darwinism persists because it’s an ideology supported by people who want it to be true for reasons other than science."
