The lack of peer review is a big problem for these publications. Look at the lancet publication on vacancies and Autism. That one paper, which should have never been published, has done a lot of damage and cost lives. Lack of Geological and Paleontological review will not be as bad, but can muddy the water.

[@kyokyodisaster4842]

As someone who has autism specifically, this is a Major mess up that has effectively spawned a whole separate conspiracy in its action.

[@bkjeong4302]

Even peer-reviewed studies routinely make all kinds of wild nonsensical claims, in some cases because the reviewers know nothing about the subject and in some cases the study’s questionable assumptions cannot be outright disproven even if they’re the sort of stuff people take as fact.

[@victormark2205]

What do you mean, lack of peer review? Did you check? What does Lancet have anything to do with “vacancies “?

It makes sense that pterosaurs descended from a gliding arboreal insectivore possibly in the middle triassic and had to compete with gliding reptiles at the time like the kuehneosaurids.

[@user-iz7dh4et8z]

Hi, thank you very much having featured our article in your video! I am truly honoured but also surprised to see the interest people bear for such weird and ancient echinoderms groups! I only have but a minor correction to bring to what you said: the specimens in our article are of the echinoderm class called "Soluta". Stylophorans are another class of echinoderms that lived in the same places at the same time, but they are different.

[@RaptorChatter]

Thanks for letting me know! I love echinoderms, but honestly mostly crinoids. The others I can generally mess up, especially early on, because their phylogeny includes so many extinct groups, and I engage with them so rarely.

Really appreciate the Review series. it is fun hearing about the latest findes and possible new in sites . Could I request an episode explaining the time line of feathers . I finde it hard to know when one should picture a feathered or non feathered dinosaur. Due to changing ideas and the different assumptions used in palio art over the years. Did they co-evolve or is there an early parent lineage.

@@RaptorChatterTerrific video as always! It can be confusing because the prefixes are from Greek instead of Latin. "endo-" = "within" and "ecto-" = "outside." So, endotherms maintain their body temperature with metabolic processes inside their own bodies, while ectotherms rely on the ambient temperature for their body temps.

[@maxfish4875]

Why would anyone at Society of Vertebrate Paleontology meeting have not wanted their research discussed? If they were confident enough in their results to publish their data, wouldn't they want as many people to see it as possible? I'm pursuing a graduate degree myself, and my professor often jokes "no press is bad press," meaning the more people talking about your book (or research paper), the better. Why would this not be the case?

Most of the research has not yet been peer reviewed (often not even submitted for peer review yet), hence not wanting the research disseminated outside of the conference. Oftentimes, researchers present at conferences like SVP to get feedback, sort of a pre-"formal peer review" peer review.

Isn’t origin of life a chemistry field?

[@RaptorChatter]

Only if you skip the parts of natural selection, which lead to the first self-replicating amino acids, as well as the first cell. Those are parts of it which have been answered for a while which this paper says there's no answer for, and then tries to make a new answer for.

[@RaptorChatter]

Not quite a new species, but it's more about finding groups. By understanding the groups present we can still get some understanding of how the ecosystem worked.

[@eugenehatin.420]

@@RaptorChatter but I’m saying wouldnt it be more likely that if they found only one fragment or one bone/tooth/fossil of an animal not know. In that region wouldnt it more likely to be fraudulent or a fake find to drum up more funding, at least that seems to be the more likely scenario especially bc of the bone wars and other stuff that’s gone on in the paleontology feild

[@rappar9673]

I love digging for, finding, cleaning, and preparing fossils for myself and others, almost obsessively, but the biology is not that interesting. I guess that's why I didn't become a paleontologist, just like I didn't become a biologist. :(

[@RaptorChatter]

I mean, there are still places that need preparators, and there's a science to it as well. So you could still become one, just in that specific subfield.

[@daHarry-ec4ce]

I love these videos and appreciate the hard work that goes into such review vids. However, I'm not sure if the dismissal of the assembly theory paper was entirely justified. Overly pretentious claims in high-profile journals and the overreaching ambition of physicists in particular notwithstanding, the explanation provided in the video just waves the problem away and substitutes statistical flukes in largely unknown mechanisms for mechanistic explanations imho. to be more specific, after the mentioned first sentence (which was cited here out of context), the paper goes on to say "These laws underpin life’s origin, evolution and the development of human culture and technology, yet they do not predict the emergence of these phenomena". And, as far as I can see, that's justified. There's no law of physics that would be able to predict, even in principle, the emergence of life anywhere. The layers of self-organization between these and the biosphere we see is what's interesting and what the authors are after (again, as far as I can see). Neither the fundamental laws of the universe nor the high-level, purely stochastic version of evolutionary theory that largely ignores the underlying physics and chemistry that is so often presented tell us all that much about these, and the fact that we have so much trouble clearly restricting the potential prerequisites for life in exobiology appears to me as a symptom of this issue.

[@RaptorChatter]

The main thing with that first sentence is that the laws of physics do predict this. Tests with earths early composition and electricity (simulating lightning) create amino acids, some of which are self replicating. Those, as well as other tests on lipid creation in early oceans have led to a very reasonable theory for creation of the first cells. No assembly theory needed. If those chemicals, and those conditions (warm shallow water and high charges) existed they would create life. It happened here, it probably happened at least once somewhere else. If you get those together than physics creates self replication, and then more complex self replication. If life formed differently on a different planet it may have value. But based on the evidence present, which currently is only from earth, it isn't needed to explain life.
