This is another interesting episode. It is great to learn from all eras, sometimes getting a more generalised sense of the world and sometimes tackling one animal. It's also been a hallmark of your channel to get to know your guests and allow their enthusiasm to come through.
I must admit I usually come to this channel for the paleoanthropology..... but videos about the super weird animals that lived SO very long ago really blows my mind. Well done👍🏻👍🏻👍🏻
Thank you for the video. I visited Nilpena Ediacara National Park last week and It's well worth your time if you love paleontology/geology and live in Australia. It's easy to get to from the Flinders Ranges or Port Augusta. Access is by booked tour and only during the cooler months. There is an entire excavated Ediacara fossil bed that visitors are allowed to explore and touch. I'm so grateful to researchers like Scott who have made our planet's past accessible.
The most amazing thing was the concept of taking up a "floor" and having the imprints of a section of an ecosystem from 500m yonks ago! What a privilege it must be to work on such a project! Very much enjoyed the interview, thanks.
As a recreational diver who studied biology and zoology in college; I once dropped in the ocean only to behold a breath taking "migration" of thousands of circular purple creatures. These still unidentified creatures appeared very similar to the model of the new creature being discussed in this video. These were not jellyfish and were not merely drifting. They were migrating against the current with some sort of undulating membrane around their circular form. I'd still like to know what they were.
Sounds really exciting. I hope to hear about the not yet public discoveries in the near future. PS: It's always interesting to discover more about creation. Don't worry, I don't mean creationism, which comes from people taking all of scripture literally. I wasn't even aware of evolution denial before I came in contact with American politics.
David Attenborough interviewed Dr Droser in one of his documentaries on the ediacaran, that was fascinating already This guy takes things to another level Superb I wonder about plant life too in that era, algal mats and seaweeds must have been the basis for the food for most of those animals? I think one of the paintings shown has some seaweeds in it? It is fascinating to think just how the most basal fractal forms evolved into those that could move
Wow! Just realized I had somehow become unsubscribed from your channel. Something I know I wouldn’t have done. I don’t know how these things happen, but the one upside is I now get to binge watch what looks like over a dozen episodes I missed. Re-subscribed and looking forward to getting back into this wonderful channel. Really one of the best for up to date research and findings on this topic.
I want to study the Ediacaran when I get to graduate school, this episode was awesome! But one question, could the twist in the Quastio be evidence of the axial twist theory?
Professor Evans, I live near Fred George sink, which is only a few minutes from FSU. I wonder if you or anyone in your research department have visited the park and trails (Fred George Park)? I highly recommend it, they've recently completed some wetland remediation so I imagine the trails have gotten nicer.
Charnia or sponges may be our earliest fossil evidence of multicellular animals. This would mean they evolved from single celled protozoa maybe 200 million years earlier. Protozoa themselves likely evolved by a reduction of photosynthesis genes and molecular machinery in algae due to a predatory mode of nutrition. A new book published by Austin Macauley Publishers titled From Chemistry to Life on Earth outlines abiogenesis in great detail with a solution to the evolution of the genetic code and the ribosome as well as the cell in general using 290 references, 50 illustrations and several information tables with a proposed molecular natural selection formula with a worked example for ATP. Cheap as an e book.
Are any of the soft pre-Cambrians found in multiple distant locations, I.e. Australia and the UK? IOWs, were individual organisms types spread across the planet?
The biota of the Ediacaran is mostly different from the Cambrian, except Cnidaria (e.g. jellyfish and hard bodied corals), which evolved in the Ediacaran initially. Probably there was a mass-extinction event of Ediacaran biota between the Ediacaran and Cambrian periods that decimated much Ediacaran macro eukaryotes. The Permian-Triassic and K-Pg extinction event(s) are quite well understood, whereas the Ediacaran extinction precursor is not. For example, evidence of trap effusion of magma on land or a bolide impact.
It’s a worldview, a belief system. Beliefs are not changed by logic or “facts”. One book helps: “The Righteous Mind, How Good People Are Divided by Religion and Politics “. A very important book.
@@edwardlulofs444 I thought all of us kids as a child were very critical thinkers and didn't even believe it even if we saw it? Trust me... Oh yea LOL Did some loose something as they got older? purpose? someone closer? or they were not as critical as I think?
@ my view on a developing mind is not professional, but I see children, dependent upon their parents, will believe everything that they say, even Santa Claus. In adolescence humans detach from parents and are more persuaded by their peers. And the final brain circuits are not in place until the late 20s. I remember how my mind changed then, especially after marriage and having kids. Adults are also influenced by their peers and surrounding culture. It seems to me that very few people ever develop critical thinking. Telling someone that they are wrong upsets others and doesn’t change their perspective. As a highly trained scientist I find that people don’t want to be criticized. So I downplay my education; certainly try not to flaunt it.
When I found out earth was not really 6,000 years old I fired my witch doctor and took up Charles Darwin, EO Wilson, and Dawkins. Boy was these guys an eye opener. Carry on gentlemen. Us ignorami badly need your service.
An actual witch doctor or you mean a priest from an evolution denying church? I am a believer and wasn't aware of evolution denial until I was in my teens talking to Americans online. I think it's because those churches think Scripture has to be understood literally at all places.
@napoleonfeanor you are correct. By witch doctor I mean a clergyman and I have never believed earth is 6,00 years old. I think many people worldwide do take their holy books as facts. Holy books are not facts. They are stories. The 3 Bears is a story. All religions in my opinion are not only false they are dangerous. Religion and politics are the most dangerous and divisive systems of anti-thought and must be abolished if the species is to survive. I am not being an alarmist.
Is there any evidence for the production of oxygen via mineral processes in the deep ocean during the Precambrian? It is I think a bit of hubris for a species that is only ~300 K years old to call groups that were successful for millions of years an evolutionary failure.
Biliterians? (Sorry about spelling). How good are fingers without a thumb? Only crude motions are possible without opposing and stabilizing features; grabbing (an important evolutionary function) becomes possible. Sorry I don’t know big words; I do astronomy.
Why didn't he address the fossils found at Mistaken Point in Newfoundland, Canada? That is the other major location for Ediacaran fossils, aside from Australia. Some significant finds turned up there like the first evidence of deep sea habitation. I also wanted to poind out that oxygen levels weren't actually low during the Ediacaran. Volcanoes along the Gondwana mountain chain released lots of carbon dioxide which was converted into oxygen by cyanobacteria and this increase in oxygen allowed animal evolution to speed up.
Very nice video. The title is somewhat clickbait as 1) Quaestio barely features in it and 2) it's clearly not the first animal because it dates from the very end of the Ediacaran, and what would have come before it in terms of multicellular life? Fungi, plants, something even different from that?
Can you please elaborate on the teleological sentences? I must have missed them. Anyway I would be very excited with such discoveries to use enthusiastic adjectives, as you don't need to be serious all the time to be a scientist. Professor Evans proves being very passionate of his job.
@@valeriaceschina1955 I admire Prof. Scott Evans and enjoyed his presentation as much as anyone. Re-watching to give chapter and verse would be tedious. If you're really interested, think of it as a homework challenge ;)
What should not be debated anymore by Bio-logical Recursion to the Mean using the absolute logic of observation of "now/superposition identification of wave-packaging probabilistic correlations shaping the actual Bio-logical Clock of re-evolution elemental e-Pi-i functional recognition facts of life.., is what constitutes an "alien lifeform".

What is really being said is, a thing has been found but it doesn't tell us anything we didn't already know and more probably just luck that it wasn't found by somebody else. When do tardigrades appear in the fossil record?
I have zero negative to say, so for the algo: As a student, I would be too distracted. Scott needs to ugly up some more. The greasy hair and shaving is a start, and the hideous glasses help. If he looked like he'd had a shower, kept the light beard, no glasses, or wore flattering ones, he would be swimming in... interest. Meanwhile, great content. Side note: please tell Dr. Evans to keep up with his cardiac health. The number of forehead lines he shows when he raises his eyebrows indicates he is more likely to have cardiovascular issues later in life. We need people like him to persist, to educate, to discover.
Hey Scott, in 2011 retrieved a banded iron matrix fossilised, iron replacement/calcium psuedomorth tube worm, circa. 1850 mya. from a ROM pad at a Cloncurry copper mine, Mt. Isa inlier. It sits at my backdoor in Tassie awaiting your Edicarian introspection.

Wow would love to hear what you saw
The Ediacaran is fascinating! I made a Dickinson a plushie for my nephew 😅
That’s very creative and thoughtful of you.

Thanks for the detailed information on the marine vacuum cleaner that shows axial patterning - the "question mark", _Quaestio simpsonorum._
Excellent!! Such a well spoken, intelligent man
What an interesting guy, he’s a natural communicator.
Very informative and enjoyable. I'm new to the channel but I'll be back regularly.
Thank you all.......that was lovely. Got me to ring the bell. Previous vids got me to sub.
Thank you for this information. Very good introduction to EDiacaran period. I shall follow your futurr publications. Catherine FRance
Thank you for this post on a mysterious time in the history of life.

Oh yes, twistors are in the news again.

There were so many pancakes
Yes-- there were!😂
Every day is pancake day in the Ediacaran!

That’s a class that I would have signed up for in college. Fascinating.
This channel and Fraser Caine meet all my 'Bald Guy Interviews Scientists' needs.
I'm curious about the number of genes in a choanocyte vs sponges/cnidarians.
Comment to bump the algorithm.
Are any of the soft pre-Cambrians found in multiple distant locations, I.e. Australia and the UK?
IOWs, were individual organisms types spread across the planet?
I think Dickinsonia is found in both Russia and Australia
🎉 fascinating❤

@@napoleonfeanor Yes. That's it. Christian fundamentalism is fiercely anti-science and sees evolution as a lie of Satan (literally).
Did you _really_ believe the Earth was just 6000 years old?! Why????? 🥺🤔😟
That thing has to be one of the Dickinsoniidae
Biliterians? (Sorry about spelling). How good are fingers without a thumb? Only crude motions are possible without opposing and stabilizing features; grabbing (an important evolutionary function) becomes possible.

Check out the Ediacaran fossil Eoandromeda! Amazing.
Seems like the animals you're talking about are all scavengers. Are any of them considered predators?
Check out Auroralumina, it has been argued to be the first predator few years ago when it was first described
yes we are all bilateral to move forward looking for food expect sponges and corals
Tina Negus got screwed! Roger Mason was lucky that he had a parental unit who actually believed him.
Why didn't he address the fossils found at Mistaken Point in Newfoundland, Canada? That is the other major location for Ediacaran fossils, aside from Australia. Some significant finds turned up there like the first evidence of deep sea habitation.

No. The molecular clock says "Tonian." Perhaps an early bilateralian.
Some of the organisms you describe remind me,of Donald Trump

Excellent content as usual.
Disappointing that a scientist uses teleological language (more than once). Not to mention "incredible".
