A Weird Paper Tests The Limits of Science by Claiming Octopuses Came From Space
https://www.sciencealert.com ^ | 28 DECEMBER 2021 | MIKE MCRAE

A summary of decades of research on a rather 'out-there' idea involving viruses from space raises questions on just how scientific we can be when it comes to speculating on the history of life on Earth.

It's easy to throw around words like crackpot, rogue, and maverick in describing the scientific fringe, but then papers like this one, from 2018, come along and leave us blinking owlishly, unsure of where to even begin.

A total of 33 names were listed as authors on this review, which was published by Progress in Biophysics and Molecular Biology back in August 2018. The journal is peer reviewed and fairly well cited. So it's not exactly small, or a niche pay-for-publish source.

Science writer Stephen Fleischfresser goes into depth on the background of two of the better known scientists involved: Edward Steele and Chandra Wickramasinghe. It's well worth a read.

For a tl;dr version, Steele is an immunologist who has a fringe reputation for his views on evolution that relies on acquiring gene changes determined by the influence of the environment rather than random mutations, in what he calls meta-Lamarckism.

Wickramasinghe, on the other hand, has had a somewhat less controversial career, recognized for empirically confirming Sir Fred Hoyle's hypothesis describing the production of complex carbon molecules on interstellar dust.

Wickramasinghe and Hoyle also happened to be responsible for another space biology thesis. Only this one is based on more than just the origins of organic chemistry.

The Hoyle Wickramasinghe (H-W) thesis of Cometary (Cosmic) Biology makes the rather simple claim that the direction of evolution has been significantly affected by biochemistry that didn't start on our planet.

In Wickramasinghe's own words, "Comets are the carriers and distributors of life in the cosmos, and life on Earth arose and developed as a result of cometary inputs."

Those inputs, Wickramasinghe argued, aren't limited to a generous sprinkling of space-baked amino acids, either.

Rather, they include viruses that insert themselves into organisms, pushing their evolution into whole new directions.

The report, titled "Cause of Cambrian Explosion – Terrestrial or Cosmic?", pulls on existing research to conclude that a rain of extra-terrestrial retroviruses played a key role in the diversification of life in our oceans roughly half a billion years ago.

"Thus retroviruses and other viruses hypothesized to be liberated in cometary debris trails both can potentially add new DNA sequences to terrestrial genomes and drive further mutagenic change within somatic and germline genomes," the authors wrote.

Let that sink in for a moment. And take a deep breath before continuing, because that was the tame part.

It was during this period that a group of mollusks known as cephalopods first stretched out their tentacles from beneath their shells, branching into a stunning array of sizes and shapes in what seemed like a remarkably short time frame.

The genetics of these organisms, which today include octopuses, squid, and cuttlefish, are as weird as the animals themselves, due in part to their ability to edit their DNA on the fly.

The authors of the paper make the rather audacious claim that these genetic oddities might be a sign of life from space.

Not of space viruses this time, but the arrival of whole genomes frozen in stasis before thawing out in our tepid waters.

"Thus the possibility that cryopreserved squid and/or octopus eggs, arrived in icy bolides several hundred million years ago should not be discounted," they wrote.

In his review of the paper, medical researcher Keith Baverstock from the University of Eastern Finland conceded that there's a lot of evidence that plausibly aligns with the H-W thesis, such as the curious timeline of the appearance of viruses.

But that's just not how science advances.

"I believe this paper justifies skepticism of the scientific value of stand alone theories of the origin of life," Baverstock argued at the time.

"The weight of plausible, but non-definitive, evidence, great though that might be, is not the point."

While the idea is as novel and exciting as it is provocative, nothing in the summary helps us better understand the history of life on Earth any better than existing conjectures, adding little of value to our model of evolution.

Still, with solid caveats in place, maybe science can cope with a generous dose of crazy every now and then.

Journal editor Denis Noble concedes that 'further research is needed', which is a bit of an understatement.

But given the developments regarding space-based organic chemistry in recent years, there's room for discussion.

"As space chemistry and biology grows in importance it is appropriate for a journal devoted to the interface between physics and biology to encourage the debates," said Noble.

"In the future, the ideas will surely become testable."

Just in case those tests confirm speculations, we recommend being well prepared for the return of our cephalopod overlords. Who knows when they'll want those eggs back?

This research was published in Progress in Biophysics and Molecular Biology.

A version of this article was first published in August 2018.

Space junk comes in hot. Organic molecules wouldn’t survive the descent.

“With grammar issues.
I thought it wasn’t “Octopuses”
I thought it was “Octopi””

Octopodes? The word has Greek origins...

Yes, true. The Bible, however, did not describe the methods used in Creation. It was written so that people in the BC could understand it.

I believe what you got there is a Cuttlefish.

“”Comets are the carriers and distributors of life in the cosmos, and life on Earth arose and developed as a result of cometary inputs.””

Even if that were true one is left with the question of where did the original life come from.

That’s what I thought.
Unless they’re buried deep inside, and in a form from another planet’s civilization, which would be impervious to heat or impact.
Who knows?

Maybe they arrive as dust, and just flitter for a landing.

That very well could be. I’d think by now the downed and recovered meteorites would have been dissected for foreign elements/dust/organisms. Maybe they have been.

...I think it is not that far fetched and a more valid theory than complex life appearing from nothing.

There has to be a start somewhere. The Comet theory just moves the issue of where life started off Earth somewhere and makes the issue of how life began even harder to unravel.

Life is essentially self replicating information. Given that definition we've already seen the birth of life here on Earth: the Computer Virus. It was not meant to be a form of life , it was an accidental side effect of devious programmers. Imagine it, a silicon based form of life that lives on electricity! Good thing it has not become as adept as other living things (so far!).

The point is you can never know in advance all the clever ways nature will create life.

It’s more believable than this covid pandemic bullshit.

Thanks Red Badger. A panspermia topic. BTW, chicken tastes like octopus.

Ohmyakinbak.

If it’s all the same to youse guys, I’d like to appropriate this for the first thread of the new year. I mean, what can go wrong?

‘Face

Yeah, see...

I can’t enlarge that enough to see what’s got her, but stupid should hurt like that.

She took a dare to put a LIVE octopus upon her face.

The octopus did not cooperate..........

For those who don’t know, an octopus has a BEAK and can bite.............
