I give him A+ for the fact that he bothered to respond.
Agreed. A reasoned and thoughtful response on his behalf to a debate where both sides are often curt, strident and just trying to shout each other down.
try this term on him:
"irreducible complexity"
As i understand it, irreducible complexity asserts that even the simplest organisms contain astonishingly complex designs and functions that could NEVER be explained by random selection. Think microscopic motors, rotors, electrical systems...entire mini factories operating with such precision that they make our most advanced automated systems look like sixth grade science projects.
And they just "appeared"? Evolved?
By the way, "Darwin's finches" had only very minor beak changes -- suggesting, at best, an element of natural selection, but in no way supporting wholesale changes from one species to another.
Read "Dawin's Black Box.
