No, it isn't. Here's the paper - <a href="http://www.nature.com/nature/journal/v524/n7564/full/nature14668.html" rel="nofollow">http://www.nature.com/nature/journal/v524/n7564/full/nature1...</a> . Among other things:<p>> "The core developmental and neuronal gene repertoire of the octopus is broadly similar to that found across invertebrate bilaterians"<p>> "Using a relaxed molecular clock, we estimate that the octopus and squid lineages diverged ~270 Mya, emphasizing the deep evolutionary history of coleoid cephalopods8"<p>There is <i>nothing</i> to suggest alien DNA, and the comment from Martin Wells appears to be part of an in-joke to emphasis the unusualness of the octopus.<p>Moreover, the text at this link is a copy of <a href="http://www.ancient-code.com/scientists-conclude-octopus-dna-is-not-from-this-world/" rel="nofollow">http://www.ancient-code.com/scientists-conclude-octopus-dna-...</a> , from at least 11 days ago. I prefer links to the primary source over to a copy.
