There is a theory that special octopus genes came from outer space - (or, fancifully, from the future). I, personally, would not dismiss the 'future' idea so quicly. Remember, according to most theorists, time doesn't rally exist. That means any phenomenon that might defy the logics of time, such as paranormal phenomena, need to be kept alive on yon table of hypothification. yo.

And here's a quote from the article of my previous post: "Dinosaurs may have ruled the land 66 million years ago during the Cretaceous period but the oceans belonged to the ammonites. But volcanic activity and climate change already placed ammonites under stress. The asteroid impact that ended the dinosaurs’ reign provided the final blow. Only a few dwindling species of ammonites survived. Today, the ammonites’ oldest surviving relative is the nautilus. Will it survive the sixth great extinction? Will the whales and marine mammals? Will the human species?"
The nautilus is the ancestor of the octopus.
