...Darwin's theory was that a process of random mutation, sex and death, allowing the "fittest" to survive and reproduce, and the less fit to die without reproducing, would, over the course of billions of years, produce millions of species out of inert, primordial goo.
But that's not what the fossil record shows. We don't have fossils for any intermediate creatures in the process of evolving into something better. This is why the late Stephen Jay Gould of Harvard referred to the absence of transitional fossils as the "trade secret" of paleontology.
Those missing 'transitional critters' are the "gaps" in Darwinian science. IOW, the theory is nice; but it can't be proven.
And Coulter goes to the heart of it:
These aren't scientists. They are religious fanatics for whom evolution must be true so that they can explain to themselves why they are here, without God. (It's an accident!)
Any evidence contradicting the primitive religion of Darwinism -- including, for example, the entire fossil record -- they explain away with non-scientific excuses like "the dog ate our fossils."
While Coulter nails the theology (there is no God), she didn't mention the philosophy which resulted from Darwin's fevered imagination: Progressivism.
And yes, there IS evidence that homo sapiens 'evolved' from Cro-Magnon to the current form. That's what JPII referenced when he said that 'evolution' was viable as a theory.
But the Progressive/Darwiniacs are incapable of explaining the soul. They are incapable of reconciling "Progress" with sin. THAT is the problem that they'd like us to forget about.
