http://www.newsweek.com/alien-octopuses-outer-space-930942 Yeah. I'm not a biologist. But I can tell you the article is tripe. The claim that there are no octopus fossils is bogus. There are a lot, considering the animal is a soft-bodied organism that lends itself to full biodegradation. The implied claim that octopi have no evolutionary ancestors is also bogus, seeing as how there are plenty of fossils of nautiloids and even soft cephalopods from 300 million years ago. Also, the octopus has the same chemical makup and DNA-RNA-protein system as all other animals on Earth makes it extremely unlikely to have come from some completely alien source. Also, are we supposed to believe that octopus eggs would not only survive an impact even that would result in an interstellar comet coming from a destroyed planet, but that the eggs would somehow adhere to the comet? What are your thoughts?
