- 🌍 Since everything has a beginning... What were the first creatures to live on Earth? It's just one of many seemingly unanswerable questions.
Since the appearance of life 3.8 billion years ago, life on our planet has remained in the state of a simple organism for billions of years... until the first complex life forms appeared.
If you've ever heard of the Cambrian explosion, you'll know that it's an intriguing phenomenon, due to the huge diversification of life, even though before the Cambrian, there were virtually no multi-cellular animals.
And for a very long time, the transition from the Precambrian microbiotic world to the appearance of the Cambrian fauna remained a mystery.
So what happened between the Precambrian and the Cambrian?
🔥 As a reminder, videos are published on SUNDAYS at 6pm.
-------------------------
💥 The Fascinating Ediacaran Period:
- It's 1946 in Ediacara, a mountainous region in South Australia. Buried and well-preserved fossils are discovered in rock strata dating back hundreds of millions of years and belonging to no proven geological era. This exploration is full of surprises.
At first glance, there's nothing special about the rocks of Ediacara. Except that they tell the story of the Earth in chronological order. Thanks to these rocks, we've been able to echo the questions that have remained unanswered until now, notably those linked to the origin of life on Earth.
In the meantime, analyses are being carried out to pinpoint the exact era of the geological formations and determine the age of the newly-discovered fossils. It should be noted that similar organisms had already been spotted elsewhere before, but at the time they were attributed, without much conviction, to the Cambrian fauna.
Stratigraphic, paleontological, relative and radiometric dating studies, combined with examinations of the organisms discovered at Ediacara, revealed that they did not originate from the Cambrian, but rather from an earlier period.
The chemical composition, texture and stratification of the rocks clearly indicated that the geological formations examined dated from -635 to -541 million years BC. What if we had just learned of an unknown period in our past, between the Precambrian and Cambrian eras?
We know this period today as the Ediacaran. A recently-discovered era, yet it embodies the very birth of life on Earth.
The fossils discovered at Ediacara in Australia date back to the end of the Precambrian super-eon, the first and longest period in Earth's history, spanning 4 billion years.
It's also the least known, as there are very few direct testimonies of this remote era.
With the discovery of the Ediacaran, we have succeeded in dusting off the vestiges of the past and unlocking the mystery of the Precambrian.
In 1957, as the fossil study continued, a momentous event occurred at Charnwood, England. Among the rare and protected species found in the forest's geological formations was the fossil Charnia Masoni.
The latter visibly resembled fossils previously spotted in South Australia, notably in the Ediacara shales, and in Namibia in the 1930s, which then seemed devoid of any trace of life.

He states that this "seems like a meager collection..." But considering this was Almost a BILLION years ago..the fact that they have several of these fossils is nothing less than Miraculous
The Ediacaran period was 635 - 538.8 Mya.
That "almost" gap betwen 1 Bya and 635 Mya encompasses more than half the total known time of complex multicellular life on the planet, almost twice as long as the mesozoic during which dinosaurs were the dominant form of life 😅
A billion years....how does one frame such a thing in ones mind? And we can look at things that were living then....when I try and grasp the relatively small amount of time...7 to 8 hundred thousand years since we shared a common ancestor with chimpanzees it's nearly impossible for me... but a billion years....
@@user-em5qh9he6e 7-8 million years since we shared a common ancestor with chimpanzees. 7-800 thousand years was about the time homo erectus existed.
I love the soothing professional and well pronounced voices of most nature documentaries and educational showcases. This is not that.
Some people say it's an AI voice. I think they may be right.
Voicing on final "n"s driving me nuts
I've found at least two weird speaking spots so far: "Underwater Waters became" and "The Ice Cap could be heard hundreds of metres below the surface."
It looks like Forrest Gump has done the voice on this documentary XD
@@catherine_404 nobody reads out i.e. but it is used in writing.
You forgot The Great Oxygenation Event, which itself was a colossal extinction event in and of itself.
Microbial life was never replaced by complex lifeforms as indicated in this video because the reality is such lifeforms still exist today. Complex lifeforms did not replace them but existed in addition to them.
I think he meant it as the dominant life forms?
@@Other-eyenewsflash, microbial life still dominates.
There's more DNA in you that's not you, than is.
@@Terkinstein Newsflash, Einstein, omnipresent is NOT the same as dominant.
@@philsurtees Omnipresence, is a term of certainty and is not a fact of reality. It implies no exceptions.
Dominance is real. Microbial life are consuming you as you read this sentence, they will eventually dominate you too.
@@Terkinstein Pretty much.
I love the way that people think that the Cambrian Explosion was the start of true multicellular life. It is just a time period where fossils have so far been discovered.
There is fossil multicellular algae that is 1.6 billion years old. Sponges that are 800 million years old.
Science requires evidence.
So go find fossil evidence.
The ediacaran life forms filtered the water to withhold nutrients. Eventually the shallow sea was transparent and light sensitive organs became a valuable asset. Prey could be hunted by predators. Speed, camouflage, defensive shells, teeth, spikes, claws and weapons came along. The cambrian explosion was simply an arms race.
This one comment is more informative than the entire hour-and-a-half-long video.
@@gaminawulfsdottir3253 Thanks, it made my day a little better to read that. We don't know for sure, but I picked up the idea from PZ Myers, I think, and it made a lot of sense. Even to this day similar filter organisms are cleaning vast amounts of water and it is a predatorial life style about as simple as you can have. I sometimes encounter Porifera, as a scuba diver, sponges, and these are very very early animals. Filter organisms, no movement, just pumping water through.
I'm pretty sure we now know the Ediacaran biota like Dickinsonia can be definitely classified as an animal because of the cholesterol found in it.
Saying "million years bc" is redundant when "million years ago" is just as accurate and avoids the bc/bce & ad/ce nomsense. 2000 years is insignificant when considering 500-600 million years. And the whole "negative" notation has to go!
Change playback speed to 1.25. It almost sounds like a person without such exaggerated speech
brilliant

this was really good, im glad because after all these years it helps explain the beginning of earths evolutionary process 😊😊
I enjoyed the video, the narrating was spot on. I noticed a lot of haters in the comments. I would like to see them put together a video like this.
Your video of ads kept being interrupted by small bits of watchable educational material.
Gotta get an ad blocker bro
@@Ben-uz6qp Unfortunately I watch on an Android TV. Don’t think there’s an adblocker for that.
I hate when my ads get interrupted by education... TH-cam should really work on fixing the problem!
@@thomass2451I don't know if this trick would work on a TV the way it does a phone, but have you tried scrolling to the end and restarting? Takes the ads out for me.
@@thomass2451 there is. Adguard. It's the first result on Google lmao
Sounds like Forrest Gump has done alright. Voice-over work and all.
I can’t unhear it now. Haha.
There was that girl in Scotland or England that found the first fossil before the Cambrian though it’s credited to a boy who reported second since they didn’t believe her.
Think about David Attenborough, his voice, the soothing iconic life he brings to documentaries. It matters. If you cut cost, cut it on visuals not narration.
i had to mute the weird voice
@@sbcwylie
Talked like Forest Gump.
Put it on 1.25 speed. Almost seems normal. Almost. I think it's funny af myself though.
When AI takes over the world, this is what your new master will sound like...
@@GrimReaper_sGhost right? seems like nobody realizes this is 100% AI, from script to voice
The thumbnail is really misleading. There were no fish in the Ediacaran.
The purported images of the Trichoplax organism are incorrect also. The images clearly show one celled amoebas and paramecium ciliates ... Trichoplax has no vacuoles or organelles visible on low power ... Trichoplax looks like a disorganized mess of throw-up when viewed through a low power microscope ... They are multicellular, a very primitive multicellular organism ... 😎😎😎
dogs like pizza 🐕💚🍕 yes there were. that's a cactus fish 🐠 dogs like pizza 🐕💚🍕
Dude I’m SO SICK of this page (and a few others) that use terrible AI images for thumbnails.. it’s like whoever is behind it just thought it looked cool and that triumphed over any basis in reality (even though this is a scientific subject)
Yeah they should have had a penis worm on there if they wanted to be edgy.
@@alishaharding478
Excellent video. I’m always on the hunt for details and new information, not the worn out superficial junk that’s full of lazy errors. Thank you.
As I'm watching this I am overwhelmed with Spiritual connection with the MEGA past ! Evolution is Creation in prosses.......
Fascinating stuff but the Forest Gump sounding narrator was the icing on the cake.
Holy shit! I didn't catch that until reading this comment. Now I can't un-hear it! Lol 😂😂😂😂😂
"Mama always said Ediacaran animals from 600 million years ago could not have traveled such great distances. They likely lived on a hypothetical Super continent from 500 - 540 million years ago"
Interrupted by add*
"...and that's all I have to about that"
Hey I have ADHD.
This was so entertaining that I actually sat down and watched it straight on through well I had to take about 3 breaks but still I came back and finished it.
I'm not sure if it was the subject, the narrator, the story writing or perhaps the visuals but I stayed with it.
Good job 👏🏼
°~•.☆.•~°
It's great that you enjoyed the video. However, it's literally an AI voice that most commenters, including me, find really annoying. I can't listen to this, at all.
@@stickyrubb I have reading comprehension disorder any type of Audible Voice is find by me.
@@you2angel1 Aha. Then I'm glad you're not bothered by it c;
This is a synthetic voice, clearly. No person speaks like this.
The edicaren was a story of life diverging one group towards animals another towards plants, the animal life had digestive systems the plant still absorbed its food from its environment, this was a progressive development throughout the edicaren, mobility and digestion for animals and static filter feeders for plants this was the basic direction during the edicaren, the set up for the Cambrian explosion of life. Plants and animals slowly diverged. The Cambrian was about animals developing a prey drive the application of energy when discovering a food source, predator and prey ecosystems✌️❤️🇬🇧
Makes a huge difference to increase the speed to 1.25. Sounds closer to a real person
Thank you cause this is good content but putting me in zone out mode with the audio
@@natashapearson792I watch this in my bed and it helps me zone out.
I listen to ALL videos at this speed on TH-cam
Unfortunately I misunderstood your comment to I put it at 0.25 speed.... I think I summoned a "slowed" remix of Forest Gump's voice
Thanks, FORREST Gump is almost gone...
Narrator really pushes the end of those woRRDDSs..
"Before the CambriuhHHNn, there were virtually no multi-cellular animaaAALLs."
What a strange way to speak.
And isn't it annoying?
a little Forrest Gump-y
@@joshuadowdle9691 😆😆😆
@@Kattastrophynx Oh yeah, JenNAYYY
Great video thanks😊
It’s pronounced ee-dee-AK-er-in. The emphasis is on the third syllable.
I spent the first 20 minutes trying to figure out HOW it was meant to be pronounced.TY
super interesting but way too many advertisements
(and yes I used to have an ad-blocker until YT blocked viewing videos completely when it noticed there are ad-blockers)
The robot narrator is so distracting.
Cam-brian, not Came-brian. ChatGPT write this script for you? 😂
wrote and read by AI
At 43:21, the narrator says, "and attached to rocks SHELLS, and…." What "shells"? Mollusks had not yet evolved. Please explain the origin of the "shells". Besides the excellent history of early Life, this video is impressive for the geology it teaches.
"Minus 635 to minus 541 million years B.C.?" If you go back in time from today you reach B.C. a mere two thousand years ago. In the context of a timescale half a billion years long, the two thousand year distinction between B.C. and A.D. is insignificant: you couldn't measure it with a micrometer. All we get from this commentary is that 'B.C.' sounds ancient to the speaker, who clearly doesn't have the least grasp himself of the length of the time interval he's talking about.
An excellent suggesrion speeding up the speech it’s much more bareable I couldn’t watch it otherwise
You can actually see parts of our Earth that look like it was once under a ocean or large bodies of water, fascinating!
Correct, the whole Earth was flooded
@@RM-lu1kx🤦🤣🤣
@@SeanMahoneyfitnessandart funny isn't it? Everything drowned. Including trees now found as upright patrified trees through all the layers of the fossil record. Whole graveyards full of bones drifted into one place in the mud stream. Marine fossils all over the continents, oil, gas, coal deposits all over the planet.
@RM-lu1kx people intent on living in their little fantasy world will never accept REAL evidence and will always look for what they want to see. You are not worth engaging with any further until you decide to move into reality.
@@RM-lu1kx Yes, it was, several billion years ago. Then, some goddess sent three animals down to find some dirt, and only the turtle came back alive, with a bit on his snoot, from which, after a thankful boop, she made the entire world. Oh, wait, I bet you believe in some other Creation story.....?
I'm quite sure Charnia was not photosynthetic. As far as I know it was often found at places which were too deep for photosynthesis. I heard it absorbed nutrients directly through its surface. (Not true skin)
There was the Ediacaran era, from about 600 to 500 million years ago. We have now entered the EdiaKaren period, with the emergence of a new genus of aggressive predatory lifeforms.
I’ve run this at a speed of x1.5. On the good side the narrator is less irritating, on the down side it’s a little more comical. On the bright side it’s shorter!
Better proofreading of the spoken narrative is required. At 41:24: 'These 3D preserved fossils were discovered in Shanxi province, central China, around 541 million years ago.' Before humans, primates, mammals or vertebrates existed.
Yes, the Ediacaran Period is pronounced: eee-dee-'AK'-ker-en. Very informative video, but I would like to know why people are sure the narrator is AI?
It's like the uncanny valley effect, but for a voice.
If he's not AI, he's doing a pretty good job on trying to replicate the bizarre affect of one.
i was wondering if its AI because of the ends of some words. like "yeaRS", "fossiLS", "worLD". Something about it just sounds off
@@ZMellinger it's definitely AI. In addition to all the hard final -s' you mention, half the end of sentence inflections rise, instead of sink. It sounds like it's mainly a series of run-on sentences.
I HATE AI narrators
@feliciagaffney1998 Hey, they're doing their best.
@@ZMellinger there are plenty of REAL people who would narrate for them. Plus... I've heard plenty of AI narrators that know how to end sentences properly.
This is yet another channel that will go on my boycott list.
Regardless of the how & why (religious beliefs, scientific, spiritual, etc.) it’s still so fascinating to know that as I type this out, this very life were living, future generations, it all started from essentially nothing. That’s so interesting, how something can come from nothing, how singular cell organisms shaped this very moment were experiencing now.
8th…lol
Do love a new wondody upload. Welll done.
Cool video
Thank you for your comment
For some reason the image of the reptile/fish dying in the snow made me so sad.
Absolutely fascinating, a few minor quibbles but over great work.
your best speech
The little oomph on the end of your narration is noticeable:)
Honestly. Im not sure if school didnt cover this or if i just wasnt paying attention in class when i was younger. Now i find this fascinating, but being honest i had no idea life had existed albiet much simpler than we normally think of, but still. That it exhisted for billions of years. From what i remember of my education the old number was in the hundreds of millions of years... The thought that life existed for so long before the Cambrian explosion... Its humbling to think that life has existed for so lon, and yet we as aspecies have only been around for a couple thousands, maybe tens of thousands of years. The thought that it took billions of years for the eye to develop, ushering in the arms race between predator and prey... Its just crazy to think of the uncounted generations that occured with life remaining relatively unchanging until it suddenly exploded in diversity. Truly the length of such a span of time is hard to grasp. Even the 65-66 milion years since the demise of the non-avian dinosaurs is hard to grasp, and thinking that life has existed for so much longer... It really puts our own brief existence in perspective.
unless your in school now this is new. Also unless you in a lab biology class usually considered advanced you haven't heard it yet. these topics were graduate level biology from the 50'-70's its still new to the general public.
And to think that all that time, life was ever developing to us. The one species on the verge of destroying it all unless we are very, very careful.
If this specific narrator yelled, it would still sound like narrating. I predict this pridefully
♪♫♥Very interesting - Thank you for sharing for this !
Thank you for your comment
It's nice to hear Forrest Gump has got a new job as a narrator for this channel
My moma always said Life is Like a Box of Chocolates 🤣
However modern research suggests...
The narrator (highly likely an AI) has very strange pronunciations and inflections. The word Ediacaran was consistantly mis-pronounced.
Narrated by Forest Gump.
Mama always said "life is an eternal adaptation, that's what life is all about" 14:00
I finished this because it is a really novel video... but I HATE AI narrators and boycott channels that use AI narrators.
There's plenty of folks who will be happy to read a script.
I’ve been doing the same with creators that use terrible AI generated images for their thumbnails that have no basis in fact or science but are used to represent a scientific subject. Like.. why? Why put time into making this just to let what you thought looked cool trump an image based in reality? (Though I’m sure there was no real human behind this video, written and read by AI as well)
@@alishaharding478 and what about thumbnails with images that don't even show up in the freaking video!! (This one, case in point) 🙄😒
I fail to understand how or why we need to say(still) 500 million years BC🐹
Why does this dude sound like his speech therapist was Forest Gump?
Because this dude is a robot.
@@gaminawulfsdottir3253Robot is who robot does...
Thank you for this high quality visual and informative breakdown of the ediacaria period…probably the best I have seen on TH-cam…and I have hunted down and watch a lot … it such a fascinating part of animal evolution and earth history ….
Yeah, that AI voice is a bit much.
THIS WAS GREAT! VERY CLEAR AND INFORMATIVE! LOVE IT!
Who am I to argue or give comment. I can not even pronounce the names correctly or conceive of the time spans.
Your perspective is still important!
don't worry, the AI can't pronounce things either.
Why is this narrated by Forest Gump?
Lol😂
Really weird that the announcer puts emphasis on certain words that don't make sense to me.
Excellent presentation. I assume that is a computer voice is being used. The way he speaks with an upward inflection at the end of sentences sounds like "he" is carefully avoiding any Vocal Fry lol.
The whole video is an AI creation from stock photos and text.
Cheap way to produce content. Not bad though, compared to many others done the same way.
@@BoB-Dobbs_leaning-left the whole thing is not stock photos. It’s clearly animations created by a human. AI isn’t that good at animation yet, and it always leaves tell tale signs if you know what to look for. The voice on the other hand is definitely AI or computer generated. This video according to the description is a translation of a French creation so it makes sense the translated voice would be computer generated.
My emotional intelligence have vanish almost all of it. I can feel happiness, emphaty, sorrow, greed, but not symphaty not love, not friendship. Like i was born to be an eremit.
"And that's all I have to say about that"
Not the most charismatic fauna, but worth knowing how the Earth has changed.
Charnia is said by experts that they resided in approx. 600 ft of water, too deep for light.
Edi-acrun, or edia-karen?
The A.I. readers will never know.
I'm old enough to still pronounce Ediacaran as Ee-Dee-Ack-ran.
I wonder if this is the Apex Chert.
This guy sounds like forest gump
Seems like AI narration bc some of the inflections are stretched. Kinda bugs
Do you have any idea how long just 1 million years is and how much biological products that would have produced, a massive amounts much thicker than what you see.
@10:30 750 billion years ago huh? billion with a B?
Could you please add your sources in commentary ?
The bible was not one of them lol
@@kathrynjaneway5346 Well that could be the worst source for anything except for the Guidebook to ncestuous Relationships, so agreed, I hope the Bible is not one of those sources :p
My scientific conclusion is that Eddy and Karen have been the worst serial killers ever
The A.I. reading this is hilarioUUUSsssSSZZZ
This was interesting
Come back, Sir David! All is forgiven. This guy (AI?) sounds like Forrest Gump!
this Studio is from some French educational studio. The voice is standard telephone company TTS. Why ? for those of you really following AI you know that A111 voices are much more realistic and have better pacing and time dynamics. As far as being AI generated thats possible. Good content still requires good reviewing and expert editing
Floor-ish-ing ??? For flourishing… Despite the information, the presentation was like a high school lecture, a list run down by the teacher. Unless there was a commercial, it was like a huge run on sentence.
This voice sounds like Borat and David Attenborough hybrid
This narrator's voice reminds me of forest gumps 😂😂😂😂
Thumbnail looks like an angry hotdog fish with a jellyfish tail
Damn, like twenty minutes in, and they're still not talking about the show's main subject.
Very good, high quality documentary but could you tune down with the US documentary fashion. Unnecessary drama, music, superlatives, etc.
Thank you for your comment
Was that raining purple later beems in this video
❤❤❤ first
Genetic entropy would have wiped all life on earth out if it was millions of years old
While I understand the need to provide information on natural history events prior to the Ediacaran in order to give context to what kind of ecology that that era arose from, I think that way too much attention was paid to the pre-Ediacaran world in this video. What you spent 15-20 minutes of the early part of this video going into unnecessarily exhaustive detail on, you could've just summarized in 3-5 minutes and moved on to the subject matter that this video was supposed to be devoted to.
(3:36) "Minus [anything] BC" would mean AD! ! ! Two thousand and twenty four years BC would be in the bronze age. Minus two thousand and twenty four years BC would be the year I'm writing this, 2024.
👍
Its CAM-brian not "kaymbrian" It's named for the Cambrian mountains in Wales not pronounced the way "Cambridge" (kaym-bridge) is said
"Minus x million years bc" is in the future. Bc counts backwards, with higher numbers going further into the future. That means negative numbers go into the future of bc. You have to either use positive bc numbers or negative non-bc numbers to refer to the past. So this video is incorrectly referring to millions of years in the future
I want you to have more music
No offence to the creators, but this is the most monotone documentary I had to suffer through. And I usually love pre historic documentaries.
Can i have permission to remake this video? Keep the video and script but ill do the narration. My voice is far from pleasant to listen to but at least i dont end every sentence with a question mark
26:00 _...cannot be classified as animals..._
⁉️ They're too mobile to be plants and too big to be bacteria
What a lot of tripe.
The narrator’s continual mispronunciation of “Ediacaran” is grating on my nerves.
He had ONE JOB
Look up the pronunciation of Edicaran. According to Wikipedia EE dee AK er en, with the stress on AK
