The tricky part of Ediacaran "animals" being ancestors to modern animals is not that we can't find Ediacarans that look like current animals. We can't even find *Cambrian* animals that look like Ediacarans.

@@RedRocket4000 The explanation, that I've heard, for that is that the starter animals were around in the Ediacaran era but they were so small we haven't found their fossils.

[@nobodyspecial2053]

The thing is, evolution can result in vastly different results based on various pressures. Take chordates for example, the phylum that contains all animals with a backbone or vertibrates. It also contains sea squirts which, if you told me without some pretty strong evidence that they were more closely related to us than jellyfish and hydra, I would not believe you. Likely in the transition between ediacrine and Cambrian, there were massive selection pressures that forced life at that time to evolve into new forms at a rapid pace or die.

Another potential classification of these 'proto-animals' might be the superorganisms we can see today in the form of Portuguese Man o' Wars and other siphonophores. They're 'creatures' made up of multiple micro-organisms that each fulfil a different role in the community, from capturing food to transporting nutrients around the body. Perhaps the parts that had the means of collecting food for the Ediacaran critters weren't preserved, or even permanently attached. Similarly, somewhat, they could be some of many other lifeforms that straddle the line between single-celled and multicellular, like bacterial colonies and slime molds. There's even types of amoeba that live most of their lives as independent individuals, reproducing asexually; except for when they all decide to form a clump that then grows itself upward into a tube shape that hardens out, like a plant or fungus; or when they encounter another individual with a similar but slightly different genetic makeup, at which point they start to rapidly sexually (kind of) reproduce while devouring all of their former(?) family members. Heck, you could even argue that _every_ macro-organism is a superorganism, since there isn't a single one around that doesn't rely on a ridiculously complex mini ecosystem of micro-organisms (and even some larger ones) to survive and metabolise their food for them. Even the mitochondrion (you know, the powerhouse of the cell) is technically speaking an _ancient_ hitch-hiker, with its own DNA and everything, and we literally couldn't do a thing without them.

[@Jack-in-the-country]

If I wasn't currently in an insomniac haze, I'd go on and on about how much I love this comment. But for now, I'll simply share with you an incredibly beautiful paper that is very relevant to your comments. It's by Ole Peters and Alex Adamou, entitled, "the Ergodicity solution to the cooperation puzzle." Here is the abstract so you get an idea, I hope you enjoy it :) "When two entities cooperate by sharing resources, one relinquishes something of value to the other. This apparent altruism is frequently observed in nature. Why? Classical treatments assume circumstances where combining resources creates an immediate benefit, e.g. through complementarity or thresholds. Here we ask whether cooperation is predictable without such circumstances. We study a model in which resources self-multiply with fluctuations, a null model of a range of phenomena from viral spread to financial investment. Two fundamental growth rates exist: the ensemble-average growth rate, achieved by the average resources of a large population; and the time-average growth rate, achieved by individual resources over a long time. As a consequence of non-ergodicity, the latter is lower than the former by a term which depends on fluctuation size. Repeated pooling and sharing of resources reduces the effective size of fluctuations and increases the time-average growth rate, which approaches the ensemble-average growth rate in the many-cooperator limit. Therefore, cooperation is advantageous in our model for the simple reason that those who do it grow faster than those who do not. We offer this as a candidate explanation for observed cooperation in rudimentary environments, and as a behavioural baseline for cooperation more generally."

Or the mouth and digestive structures we're not seeing were one organism of a colony, and disconnected themselves from the rest when they could tell the other tissues were damaged or dying.

Or .. who knows what? Hopefully someone will find real evidence soon.

I can only speak for myself on this one, but like the proto-animals and siphoniphores, I am also a ‘creature’ made up of multiple micro-organisms that each fulfill a different role in the community (me, I am the community) from collecting food, to transporting nutrients around the body. I guess the only interesting thing about me is that some of my cells combine with some of other people’s cells and produce new microbial communities, and those communities will probably also be able to use the internet. I think about this a lot.

Something I think should have been mentioned, when it comes to potential animal affinity there actually has been recent evidence looking at preserved cholesterols on Dickinsonia fossils that seem to be considered good evidence that it really is some kind of very primitive animal as opposed to a fungus or some other totally unrelated form of life. Additionally I think that Kimberella has a number of features that may potentially pin it as an extremely primitive mollusc, which would be exciting since it shows that animal life had already gone through some major radiations that would have laid down groups that exist to this day, maybe even including arthropods and Chordates!

[@admiralcat3809]

Imagine if trilateral Ediacarans with gliding symmetry became the dominant creatures living today, it would be a different and bizarre world.

[@Aztesticals]

It always hurts to hear of teacher like those at the beginning. They didn't just go check themselves to gain the knowledge of it the children lied or told the truth. They dare teach, but they care not to learn themselves

[@RedRocket4000]

Good point confirming the lie would be a good idea especially as it so crazy it has to have a source of something even if it modern in type.

[@Tishers]

Unfortunately that is a human tendency that is more universal than a stand-out exception.

[@Aztesticals]

@TishaHayes yep. And it's one where even when you are as self conscious as I am. Constantly remembering my place and centering myself. I still occasionally will find myself being dismissive of claims or new ideas that have legit possibilities and have to go read. I also will find myself just accepting stuff without additional evidence simply because it came from a source I've used prior. And then I remember that Sci show can mess up . Like when they called azidoazide azide the most sensitive explosive every made and have done so repeatedly despite hundreds of papers and demonstratrations showing that no it's not.

[@BlackBanditXX]

It's important to remember that only perhaps a fraction of a percent of all creatures end up as fossils. It's entirely possible we've just never found the ancestors of Animalia.

[@accutronitisthe2nd95]

Instead of "filtering" or going into the "bottom sediments" could Ediacaran have absorbed chemicals or minerals that were dissolved in the seas at that time?

[@NorthForkFisherman]

I think that you would have to try to figure out what concentration of chemicals would have to be necessary and for how long to support some creature of that size.

[@noway8233]

I alwsys get impress how nature give us clues of ower own past , like the fosilisation proceses , its really amazing that nature give us all this things , frozen "pictures" of old creatures

[@spacelemur7955]

Given how many gaps there are in the fossil record, it's possible that the ancestors to animals lived in a place with poor conditions for fossilization, and we will never find them.

As always, I've very much enjoyed this presentation of the History of the Earth. I especially appreciate learning new names of the Geologists and Paleontologists that made crucial discoveries, and the dates they made them. Thank you. Thank you. And please continue your work.

[@davevann9795]

Since fungi and animals have similar cellular metabolisms, and some people say that fungi branched off early on the path to animals, and some evidence exists for a pre-Ediacaran origin for fungi, then couldn't Ediacaran macro life be an early branch away from fungi and on their way to being modern animals?

[@Someone-sq8im]

You could write a doctoral on that

[@averteddisasterbarely2339]

Talking about history is one thing ! Making it a story is that you don't want to end is something else altogether ! Thank you all for your hard work !

[@rexradar9297]

Two things pop in mind. First is the Cambrian explosion may have been set of by some of these creatures figuring out how to use mineralization to build solid structures. Such an event could easily be the kettle keg that set the explosion off. Second is non linear convergent evolution. Kind of like how so many distantly related crustaceans evolve into crabs. I like the sea pen comparison. It fits my incomplete and in adequate world view.

[@moritamikamikara3879]

But what would have prompted the evolution of mineralization? I'm certain predation must have evolved first, and I'd hazard a guess that the Cambrian explosion was more likely caused by the evolution of the first predator, which in turn led to the evolution of mineralization. I'd also hazard a guess that the first ever predator was probably a free floating jellyfish.

[@p00bix]

Just want to say as someone who's been pouring through scientific literature on the Ediacaran the past few years that I'm super impressed by the factual accuracy here. Most other youtube videos on the Ediacaran--even ones made by content creators who are really good for the most part--are full of errors and often present long-refuted hypotheses made before 1990 as modern paleontology. The ONLY serious criticisms I have regards the segment from about 44:06 to 44:50. Filter feeding isn't impossible in the absence of burrowing animals. It is likely that sufficient nutrition could be gained simply through marine snow (dead cells and biological waste of surface plankton) falling toward the seafloor, and that a thin layer of accumulated snow on the sea floor could be sufficiently disturbed by non-burrowing organisms grazing on it to churn it up back into the water column. On a related note, the fungal theory for Dickinsonia's evolution is not widely accepted, with most scientists believing it was either a basal animal or represents an extinct lineage which was more closely related to animals than to fungi. And only a few scientists believe that Dickinsonia spent its life 'pressed down into the mud'; evidence has grown over the past 5 years indicating that it could almost certainly move, albeit at an exceedingly slow pace, probably to travel to areas where marine snow had accumulated. In the grand scheme of things these still aren't major issues; your video is sooo much more accurate with respect to the Early-2020s understanding of the Ediacaran than Walking with Dinosaurs was with respect to the Late-1990s understanding of the Mesozoic. And WWD is literally the poster child of 'scientifically accurate paleontology documentaries' and concerns a much better understood era in Earth's history. So seriously, amazing work!!!

[@Bloodknok]

All the focus around the start of animal life is inevitably on the Cambrian, but the pre-Cambrian period is super-interesting, and this video captured so well the mystery of ‘what happened before'

[@Asterra2]

Nice to get some updated info on this period in Earth's history. My literal first exposure to the existence of these creatures was David Attenborough's *First Life,* a two-part miniseries from 2010. While the production of said miniseries edged a little more into "staged" territory than Attenborough's best efforts-with semi-scripted interviews with various scientists-it was nonetheless a well-done program and a rare example of a modern documentary that's worth watching. The "Pizza Discs" back then didn't have an official name yet and hadn't been reconsidered as possibly something other than a single bizarre lifeform, and that's a good example of what I mean by updated info.

[@ethribin4188]

The reason Eridiacran creatures are so similar to leafs is physics. No matter how life evolves, there are most efficient forms based on physics. And life/evolution always lean towards physics efficiency.

[@gj1619]

When is a new History of the Earth video coming out? Thanks.

[@baraskparas9559]

Most of evolution occurred at the subcellular level as biochemistry and genetics for billions of years. 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. The Ediacran occurred about 200 million years after the first protozoa evolved from single celled algae by a loss of photosynthesis genes and molecular machinery by getting adequate nutrition via predation.

[@elenap15227]

David Attenborough made excellent documentary in 4 episodes called First life. It talks about everything that is mention here (charnia, ediacaran fauna,cambrian explosion and then tiktaalik and first land animals) and much, much more. Highly recommended.

[@kimberlyperrotis8962]

Why don’t adults listen to kids? They’re just as smart as we are, often more observant and not intellectually crippled by our adult paradigms. This reminds me of an anecdote where a truck had driven into and was wedged under an overpass too low for it by about an inch. Half a dozen men were standing around for ages scratching their heads about the problem, when an 8-year old boy suggested “why not let a little air out of the tires?” It worked, the truck was backed out easily, rerouted and the traffic jam was cleared. The men had been thinking about what kind of complicated equipment and procedures they needed, rather than seeing the best and simplest solution. (Sorry, I can’t properly credit this anecdote, I read it too long ago to remember the source but it’s a true story as far as I know).

Edicarians look like they are shaped to maximize surface area. so this would be great for a simple filtering or photosynthesis. fleshy leaf creatures? but not plants and somehow not really animals either. fascinating video.
