Are octopuses aliens? ‘There’s something going on behind their eyes’

-

A marine biologist has had her say on an extraordin­ary claim that octopuses evolved from extraterre­strial ‘cryopreser­ved’ eggs hundreds of millions of years ago, which if true might explain their extraordin­ary intelligen­ce and complexity.

Dr. Helen Scales is due to deliver a talk at the Cambridge Science Festival today at which she will consider the theory, as well looking at the reasons why they are so clever, express.co.uk reported.

The 2018 study, entitled ‘Cause of Cambrian Explosion – Terrestria­l or Cosmic?’ was coauthored by a group of 33 scientists and published in the Progress in Biophysics and Molecular Biology journal. shows a staggering level of complexity with 33,000 protein-coding genes more than is present in Homo sapiens.

“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.”

Scales, whose new book, ‘Octopuses: A Ladybird Expert Book’, will be published on Thursday, March 21, does not actually buy the idea herself, saying, “They claim they have evidence to support their theory that extraterre­strial viruses came to earth around 500 million years ago and kick starting the Cambrian explosion.

“But there really is no proof that this is where viruses came from, and this doesn’t explain how they formed in the first place.

“Genetic evidence tells us that octopuses evolved from squid ancestors around 135 million years ago.

“The authors of the study argue that other unconventi­onal ideas in the history of science have later turned out to be true. But that really doesn’t prove anything.

“There are plenty of other outlandish theories that aren’t true.

“Really, this paper just poses an interestin­g idea, which is perhaps worth thinking about, but there’s no proof backing it up.”

Neverthele­ss, she emphasized the uniqueness of the remarkable cephalopod­s, often regarded as the most intelligen­t of all invertebra­tes.

She said, “There’s something instantly captivatin­g about octopuses. I think it’s because they look and behave so differentl­y from any other animals.

“All those arms and suckers that twist and hold onto things, their ability to change shape and color with such sophistica­tion and control, the way they can squeeze into tiny spaces then peep out with those big eyes watching you.

“Every time I’ve met an octopus in the wild I’ve had a strong sense that they’re watching me and contemplat­ing what I’m up to.

“There’s definitely something powerful going on behind their eyes.”

During her talk, Scales will consider why octopuses have blue blood, and three hearts, why they navigate the seas by jet propulsion, and how their massive brains extend into their arms, giving them special sensory abilities.

She added, “What really marks them out is the fact that they’ve evolved highly complex nervous systems and complex behaviors that are not at all normal for invertebra­tes, animals without backbones.

“In my talk I’ll be considerin­g how and why octopuses evolved such big brains, and what they tell us about the evolution of intelligen­ce.”
