At Nature: “Octopus genome holds clues to uncanny intelligence — DNA sequence expanded in areas otherwise reserved for vertebrates.” ““It’s the first sequenced genome from something like an alien,” jokes neurobiologist Clifton Ragsdale of the University of Chicago in Illinois, who co-led the genetic analysis of the California two-spot octopus (Octopus bimaculoides).”
Oh? How was that?
“Evolution of novel genes”? Isn’t that the question at hand? Where do novel genes come from? They found “a suite of octopus-and cephalopod-specific genes” that seem to have appeared out of nowhere. As for mechanisms that “can drive genomic novelty,” their list does little more than assume that making more of existing things and shuffling them around will create novel things that do something useful. Try that with a copy machine, a book, and scissors. “Modification of gene regulatory networks” is no help, either. Stephen Meyer documented in Darwin’s Doubt how modifications to GRNs are almost always lethal, and never innovative. – David Coppedge
The researchers reach for convergent evolution — but convergent with what?
The octopus — a highly intelligent short-lived exothermic invertebrate — should sink lectern-splintering Darwinism — but then the octo does not have tenure and many of the lectern splinterers do. That’s life. But so is finding out the facts.

The smartest of invertebrates, the octopus, once again prompts us to rethink what we believe to be the origin of intelligence. The brainy cephalopods behaved about the same as lab rats under similar conditions, raising both neuroscience and ethical issues.
