"However consistent with this conclusion are the recent RNA editing transcriptome-wide data on the somatic RNA diversification mechanisms in the behaviourally sophisticated Cephalopods such as Octopus. These data demonstrate extensive evolutionary conserved adenosine to inosine (A-to-I) mRNA editing sites in almost every single protein-coding gene in the behaviorally complex coleoid Cephalopods (Octopus in particular), but not in nautilus (Liscovitch-Brauer et al., 2017). This enormous qualitative difference in Cephalopod protein recoding A-to-I mRNA editing compared to nautilus and other invertebrate and vertebrate animals is striking. Thus in transcriptome-wide screens only 13% of Drosophila and human protein coding mRNAs harbour an A-to-I recoding site; and there only about 25 human mRNA messages which contain a conserved A-to-I recoding site across mammals. In Drosophila lineages there are about 65 conserved A-sites in protein coding genes and only a few identified in C. elegans which support the hypothesis that A-to-I RNA editing recoding is mostly either neutral, detrimental, or rarely adaptive (reviewed in Liscovitch-Brauer et al., 2017). Yet in Squid and particularly Octopus it is the norm, with almost every protein coding gene having an evolutionary conserved A-to-I mRNA editing site isoform, resulting in a nonsynonymous amino acid change (Liscovitch-Brauer et al., 2017). This is a virtual qualitative jump in molecular genetic strategy in a supposed smooth and incremental evolutionary lineage - a type of sudden "great leap forward". Unless all the new genes expressed in the squid/octopus lineages arose from simple mutations of existing genes in either the squid or in other organisms sharing the same habitat, there is surely no way by which this large qualitative transition in A-to-I mRNA editing can be explained by conventional neo-Darwinian processes, even if horizontal gene transfer is allowed. One plausible explanation, in our view, is that the new genes are likely new extraterrestrial imports to Earth - most plausibly as an already coherent group of functioning genes within (say) cryopreserved and matrix protected fertilized Octopus eggs."

They're intelligent, but I don't think they're smart enough to build and fly spaceships.

That theory has been around for a while. I believe other papers were claiming something similar years ago.

I don't believe it but there are a lot of fun ways to spin it into a movie plot. You could turn it into anything from Mars Attacks to Prometheus.

When simplified to that argument, seems like a plausible proof of panspermia, or multiple abiogenesis.

Actually just from looks alone I'd say the platypus was an alien. But the article was good for a laugh.

That's stupid. We all know there's several types of aliens but octopi aren't one of them.
