Let me explain this to you very simply: If coral don't have TLR-4, you're screwed.
Bad news: Coral do not have TLR-4. :-( Poor you!
Other bad news for Evolutionary Theory is that TLR-4 (heck, or TLR for that matter!) hasn't been found in lobe-finned Fish (even though Evolutionists claim that lobe-finned Fish are a key branch in the path to mammals).
