Evidence of the octopus evolution show it would have happened too quickly to have begun here on Earth. Published in the Progress in Biophysics and Molecular Biology Journal, 33 scientists have declared the invertebrate sea-dweller an alien whose eggs landed from space.
But the scientists go on to make an even more extraordinary claim concerning octopuses, which seem to have evolved on Earth quite rapidly something like 270 million years ago, 250 million years after the Cambrian explosion.
The paper states: “The genome of the Octopus shows a staggering level of complexity with 33,000 protein-coding genes more than is present in Homo sapiens.
“Its large brain and sophisticated nervous system, camera-like eyes, flexible bodies, instantaneous camouflage via the ability to switch colour and shape are just a few of the striking features that appear suddenly on the evolutionary scene.
“The transformative genes leading from the consensus ancestral Nautilus to the common Cuttlefish to Squid to the common are not easily to be found in any pre-existing life form – it is plausible then to suggest they seem to be borrowed from a far distant “future” in terms of terrestrial evolution, or more realistically from the cosmos at large.
“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.
“Thus the possibility that cryopreserved Squid and/or Octopus eggs, arrived in icy bolides several hundred million years ago should not be discounted as that would be a parsimonious cosmic explanation for the Octopus' sudden emergence on Earth circa 270 million years ago.”
