I haven't changed the subject. Coral is not an ancestor to humans. There is no path to explain.
Find a college level textbook or a journal that says it is.
I have found the article discussing the genes shared by coral and humans. You have simply misread it.
Ah, now you're back to coral and off of Nobels for Southack. How refreshing!
Too bad that there is no evolutionary path for traits in coral to make it into humans, though. That DNA evidence alone dooms Evoltuionary Theory to the dustbin.
