This thread, plus the original article, and the links therein document the endotoxic recognition and signaling in coral that is not in Fish (but which we know is in humans): http://www.freerepublic.com/focus/f-news/1823622/posts
Once again, list these genes that are allegedly present in coral and humans but not in fish. If you’ll read this thread you’ll notice I repeatedly point out to you that you have no clue what any of these genes are, you have no clue about what genes fish might have, and you have no clue about what these genes even do. (All of this is completely consistent, since from your other posts you maintain the trend by having no clue what an allele is.)
The news (not scientific) article you point to says zilch about fish, nor does it even say what the particular genes in question are. If you would read my posts without the words going into your eyes and out your ears, you would realize that they mean that coral have an ancestral Toll gene and humans have an expanded but related set of genes. Fish, which are not mentioned there at all, have a set of genes that is smaller than that of humans but larger than that of corals. All of this is consistent with the evolutionary process.
