Obvious mistakes in the design of organisms.

 

Darwinism can't overcome the information problem! The cell is too complex. It had to be designed. Bacterial flagella of the world, unite!

Iirc, the ID proponents claim that RLN is a great design, because it develops like a river, going with the flow as the body develops from birth. Since God made the rivers, and they're so well designed, the RLN MUST be a great design as well!

Well, that would be a pretty silly use of the "design inference." I read a chapter from an ID book that was supposed to address instances of suboptimal design in nature and all it really did was weakly criticize a couple examples that were the easiest targets and then act like it had refuted to whole idea. Pull a silly "purpose" out of one's ass (e.g., the crappy design of the human eye keeps the retina warm), make some specious and/or trivial claims (e.g., junk DNA isn't really junk!); therefore, suboptimal design isn't a problem.

 

I once wrote out a detailed compilation of evidence for evolution at the request of a creationist friend of mine and the response consisted of a bullshit "rebuttal" of one or two of the arguments (there were dozens) and then a "and the rest are similarly fallacious" dismissal. GTFO.
