*Snerk!* You're the one who's had to go through gradually changing his objections as each one is demolished.
Your original objections and current opinions:
- Coral and humans have endotoxin recognition, fish do not. Corrected, now you think coral and fish do not have endotoxin recognition, while humans do.
- Coral and humans have TLR-4, fish do not. Corrected, now you think fish and humans both have TLR-4, coral do not.
- Coral have TLR genes that humans have and fish do not. Corrected, now you think that coral had one TLR gene, fish have several, and humans have even more.
You've run out of objections.
