I had to smile at this report.
The paper ... attempts to tackle the question of how life originated here on Earth. The researchers embrace a number of proposed explanations and discuss their implications, but one particularly interesting note is their proposal that cephalopods (squid, octopus and cuttlefish) may have originated somewhere other than Earth. Whoa.
“Evidence of the role of extraterrestrial viruses in affecting terrestrial evolution has recently been plausibly implied in the gene and transcriptome sequencing of Cephalopods,” the researchers write. “The genome of the Octopus shows a staggering level of complexity with 33,000 protein-coding genes more than is present in Homo sapiens.”
The scientists challenge the belief that modern cephalopods evolved to their present form here on Earth and propose the possibility that those we see today are the descendants of creatures that arrived on Earth frozen in an icy comet.
“Its large brain and sophisticated nervous system, camera-like eyes, flexible bodies, instantaneous camouflage via the ability to switch color and shape are just a few of the striking features that appear suddenly on the evolutionary scene,” the paper says, pointing to the possibility that this “great leap forward” in complexity was due to “cryopreserved squid and/or octopus eggs” crashing into the ocean on comets millions of years ago.
There's more at the link.
I think that's been thought of before . . .
