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.

That reminds me of one of my favorite exchanges with my wife.

Her: Can today POSSIBLY get any worse?

Me: You shouldn’t ask questions you don’t want the answer to.

It started pouring about 30 seconds before the kids made it to the car. My phone took us home by a route we haven’t used before, but it was okay.

Kathleen has a class tonight, and I have the Stewardship Committee, and I think DP and Tom are going out for drinks.

I had a nice day. I visited the Gaston County Museum, where the employee was super helpful and informative, and then I sat in the library and read a novel I started there yesterday. There’s been a murder, so now I’ll have to request the volume from Mecklenburg Library!

Lucky you!! I don’t even have the map feature turned on on my phone. Google was tracking me and I don’t like that at all.

You’ll be having a busy evening and I’ll be trying to stay awake long enough to read Scriptures! LOL!

I wish now I had gone to the Pioneer Museum in Hurricane, but I guess I was afraid I was going to stay in there on my feet until I wouldn’t be able to walk. I hate when I do that, but then, I love museums and hate to leave until I’ve seen everything! ;o]

Now I have to go turn on the mattress pad so my bed will be warm. I need to replace this one ASAP. Mattress pad, I mean. I was going to do that before SSA tricked me, but it will have to wait a bit, now.

It’s interesting how things evolve over time. Back in 1977 the Alan Parsons Project wrote “The Voice”

It’s almost a feeling you can touch in the air
You look all around you, but nobody’s there
It’s been a long time now since you’ve been aware
That someone is watching you (he’s gonna get you)

But then, in 1982 they wrote Eye In The Sky:

I am the eye in the sky
Looking at you
I can read your mind

So, anyway, they seem to have seen Google coming.

Yeah, sometimes, those spaced-out song writers were ahead of their times and didn’t even realize it!

That hard living seems to have shortened all their lives and shorted their brains. But we had a lot of good dance music!!

Kitteh wants the royal belly to be skritched.

Good morning. I hope you slept well.

Once again, I’m waiting for the water to heat up enough for a shower. This is getting old and boring. I can’t just start my day with a shower. I have to wait until the water is hot. By then, I’ve usually lost interest in it. I do it, but it means everything else I do is so late. Hopefully, it will be ready in a few more minutes. I hate getting up 90 minutes early just so I can shower.

Outside of the shower, the only thing going on is the sofa/futon frame. YAY!!!

Good morning. Not bad, thanks. None of the youth is up yet. Frank and Kathleen are tired after two days of Wilderness Skills! They’ll go again on Friday.

We’ll go to the library later.

I’m going to try that shower thing again, and then when I get back, I think we’ll do that Moving Thing. Again. It’s time.

I think this may be the first time I've remembered before the end of the day. I'm not that big of a fan, but for those of you who are:

May the 4th be with you!

We may have to add therad to the official list of misspellings like byos and owrk.
