Sadly, I can't trust anymore in anything that a Russian would claim. They just have too much incentives to cheat at this moment.
Until proofs will speak by themselves in an incontrovertible way, meh... big claims need big proofs.
All this late claims about X revived after zillion years by warming prince's kiss in a lab, circumnavigate carefully the fact that ice can have deep crevices. Plus, we don't know anything about the biology of this roundworms; Why are we so sure that they don't migrate actively deep into the soil? most free roundworms known by science can move trough the soil. Basically is what they do all the time.
I want somebody addressing seriously those two points before to form an opinion.
Some footnotes: Sadly the genus is not new (That would made the case much more simple). There are at least 39 extant species of Panagrolaimus (Rhabditida, fam. Panagrolaimidae) know yet. So we aren't talking about an isolated, last-of-their-kind, live fossil.
Also not exclusive from permafrost. Relatives of this species had been found in China, USA, South Spain, Iran, Peru or India.
They move fast and are very active. They aren't parasites, and feed on bacteria and microorganisms
So they live in soils with decaying organic matter. A species is common in agricultural soils in California; other is often found in dead flower heads of ornamental Asteraceae (=family of the sunflower) like Chrysanthemum or Zinnia. There is a third associated with leaf litter and bark beetles in Utah, and a Peruvian species appeared in exported rotten ginger rhizomes.
So we are talking about a kind of nematodes closely (but not exclusively) associated with agricultural practices, sometimes in temperate or Mediterranean climates
Well. The scenery does not suggest endemic Siberian fauna, or points directly towards -46000 years ago, but neither discard it anyways.
I still think that the proofs that an animal lived for 46000 years (much more than corals?) are circumstantial at most, and shouldn't be taken as definitive
The closer known relatives of this worms add more context. Some species of Panagrolaimus were moved later to the genus Propanagrolaimus comprising freshwater aquatic species. Three species inhabit tropical rivers in India and had been found associated to dead roots of Lotus
The roundworms were found at 40m deep, but this is not moon-distance level. I can totally imagine as plausible the scenery of an aquatic roundworm living among water lilies roots in the muddy bottom of a 35m deep Siberian lake and then going the extra mile down to reach buried yummy decay. This animals don't live in the surface necessarily. I could see also the animal also being dragged or swimming down a partially thawed 5 milimeters wide crevice attracted by buried decay without contaminating it.
Other close relative genus live in the bark of big tropical trees in Iran. We had seen a lot of videos of tall conifers falling lately when the permafrost gets unstable in warm weather. Falling trees can inject seeds or animals deeply in a muddy soil. I can imagine an 80m tall pine with worms in its bark falling, stabbing the permafrost, and then sinking by its own weight a little more each spring until laying at 40m deep. I don't thing that would need 46000 years to this organic matter to disappear completely while it feeds the microorganisms that would in turn feed thousands of generations of roundworms.
So yes, the decay could be prehistoric, but the worms could be still much more modern.
The main difference in that cases is that the article would be more difficult to sell. Would end published in a more specialized, perfectly legit and decent, but lower rank journal. Free-living roundworms aren't rare, most of them are simply ignored. The number of people in the planet able to navigate the taxonomy of the zillion species alive could be counted in the tens or thousands probably. I had a lot of headaches dealing just with the parasitic of vertebrate marine animals, and this is just a tiny fraction of the total.
That’s what the journalists are there for though - to do double checks and verify sources. This is CNN, no?
I’m against what Russian forces are doing across the board, but explicit Russophobia gives that regime exactly the kind of ammunition they want. They can paint this picture that we’re all just biased and out to put them down as a civilization and as innocent a society. Even when it’s scientific discoveries.
Sadly, I can't trust anymore in anything that a Russian would claim.
You know, that's exactly how I feel about CNN. There was somebody once who claimed they only had 'Fake News'. I think he was right about CNN, at least.
