Nice videos, but as a biologist, I have a couple of comments: Chordates name does not come from the nerve, but from a notochord - the structure made from the connective tissue that runs through their body. The nerves run above this structure and the digestive system below. The remnants of notochord in humans are spinal disks. Nerves are derived from ectoderm, while notochord from mesoderm. Also, you should give species binomial names according to the standard - where the genus name is written starting with a capital letter, but then the species name is not capitalized so it would be Paradoxides davidis not Paradoxides Davidis.
I'm sick of getting interested in a video only to have a commercial slapped in my face. one of my favorite channels just got a DO NOT RECOMMEND CHANNEL. I'm in a bad mood now.
"What was the earth like 500 million years ago?" Like riding a bicycle. Except the seat is on fire and the bike is on fire and the ground is on fire and everything is on fire because it's hell.
Oh yeah, life in the ocean was much more comfortable-too comfortable indeed, as it was explained in the film! But there is a living fossil species that changed little since the Triassic when they first appeared, called Notostraca Triops, or commonly "tadpole shrimp" (they're in fact neither). They live in extremely arid areas, in temporary seasonal pools, and lay eggs that can dry up so hardily that they persist in soil for decades and even pass through mammals and birds undigested. When there's enough rainfall to form pools, they soak up and hatch, grow into adults in a matter of days and reproduce before the pool dries up. Life, once started, finds a way...
Like climate "science"? Pandemic "modelling"? Or Attenborough just making shit up? I trust a youtuber more than a scientist these days.

Began watching this and his other channels while reading Adrian Tchaikovsky's Children of Time... Can't believe how much real life appliable knowledge I've acquired since then because of this man. Thank you for your dedicated service to humankind!
Great book. I picked it up in a charity shop, didn't know anything about it. I was, at the time, keeping a Regal Jumping Spider as a "pet". Made me look at her in a different sort of a way :)
An interesting thing about echinoderms is that in their juvenile form their are bilaterally symmetric. The 5-part symmetry they're so famous for is a secondary adult characteristic.
I subscribe to a number of UA-cam channels on a variety of topics, but it's so nice when autoplay brings me to this one. Just a calm, serene presence, a respite from all the craziness of current events. Thanks for your high quality content. 💗
When I was a child I was given a beautiful fossil of a trilobite. When told of their extinction, I refused to believe they were gone. Spent many a summer searching field and stream trying to find proof of their continued existence. Didn't really give up until I was about 12.
Those fast radio bursts remind me of the discovery and exploration of quasars: "At first, astronomers had no idea what they were seeing." - IMHO that is the beauty of science.
I don't understand why there was a positive carbon isotope excursion in limestone during the SPICE event? If limestone is the dead carcasses of foraminifera why would those foraminifera have taken up more C13 than normal? Pete, David, and Leila, You're the best! How your brain decided to weave Cape Code and the SPICE event together is singularly astounding! Who thinks of stuff like that? Your videos are packed with such temporally separated comparisons. I love it.
"Finally, the helicoplacoids have the appearance of a towel wrung out to dry, if that towel happened to be made of rigid armor" In other words, not a very good towel, is it?
The last four years have been trying times, both for myself and for humanity as a whole. Covid, the ongoing wars, and the continuing climate crisis have taught us of the hubris of the scientific community and those who govern our societies. On a more personal note, I have had to 'lock down' due to health issues. My continuing problems with chronic obstructive pulmonary disease were exacerbated by cancer in my chest. Throughout this period, I have had the joy of watching and listening to this and the other two channels by these amazing creators. These videos are the very definition of Edutainment. Thank you to all involved in the researching and producing of these works of art. Also, thank you to my co-commentors (sic) for your well moderated comments and praise 🙏
I must have watched (and listened) to this channel a dozen times already. At the time of writing this comment, I have just done watch number three of this episode. It's easily one of the best pieces of edutainment ever 🙏
The Pre-Cambrian and Cambrian periods are those that fascinate me the most. So much is shrouded in mystery, and yet we can still make good guesses to what happened and how the world looked. Stuff of dreams for me 🙂
Thank you guys heaps for improving on the audio mixing from the last video. Much less distracting this time around. I am looking forward to the next post on History of the Universe and this one. Keep up with the good work
Hi Pete and friends, just wanted to chime in and say how much I love the channel. Truly one of my favorite channels to escape to, learn, and be entertained all at the same time.
I've loved your videos since I first saw them. You've talked all about animals and the Earth. Would you please do a video/videos about plants in the Earth's history. Ie. the eras of gymnosperms, angiosperms etc, what effect they've had on animals and vice/versa. Or "living fossils". Something of the sort relating to plants.
The story of our earth is a beautiful and violent yet also peaceful story, every time something happens, the cosmic hammer of nature comes swinging to change it again… Also fun fact: there’s over 25,000 species of trilobites so far That We Know Of…
@@beachbum200009 I used to go houseboating on lake Powell, back before it developed it's infamous bathtub ring. The side canyons are a dream to explore. But the wind can get a bit nasty on the lake. As a kid I remember one storm blew us out of the cove we had picked for the night.
Finally a new episode! I have watched all 28 former episodes (this is No. 29) - they are the best towards Earth's history I have ever found. Please continue this series through the periods of Earth's history until (and including) the Kainozoic. This series is such a treasure of knowledge, it should be on the curriculum of schools or even universities.
Great UA-cam Channel as well as Video with great analysis, voice, animation & feelings of reality. We are always with you plz upload videos on regular basis, you waited us long. Thank You Very Much 😊
These works are amazing! So much better than anything on mainstream TV. In fact, the last great series (on terrestrial TV) of this type was Aubrey Manning's Earth Story, over a quarter of a century ago!
Got to admit, I’d love that. Of all creatures that have ever existed on Earth, my favourite is the Trilobites, with Hallucigenia coming a close second.
Again, asking for a way to support you besides clicking ad links and such! If you get a Patreon or something with ad-free videos, I'd subscribe in a heartbeat! Thank you so much for the work you do: these videos, these channels, are hands down my favorite on UA-cam!
This is truly an amazing world we live in and I still can’t get it in my head how old it is and at one point why did the Dinosaurs live here and no humans 🫣🫢🧐😳👊🏻❤️

A fascinating documentary on this most interesting time in the early history of complex life. This is such a brilliant channel, with great topics that are covered in detail yet are presented in a highly engaging manner.
Nice lead in to the sponsor 😉 it's always pleasant to get a joke with the pitch. Fantastic video as usual, I watch them all many times and my kids like them too. We listen to them before bed It's so nice to rest and learn together at the end of the day 🥰
Fascinating. Despite my interest in Biology & Geology going back decades, there seems always something new to learn. Thank you, once again, for not dumbing-down the content matter in the quest to keep it entertaining.
I just love your work. So great to have new material to enjoy! Btw, my all time favorite has been The Boring Billion. Thank you for being uniquely awesome!
Just like a fast radio burst, this channel's videos are worth waiting for. . . I love this channel! My joy is boundless. There IS a Troll Research Station!
I absolutely Love these videos about earths geologic history 😊👍 Even more then the history of the univers videos of yours, tho I realy enjoy those too. Such a facinating existential subject.

Also fun fact: there’s over 25,000 species of trilobites so far That We Know Of…
crazy to think that something as complex and world breaking as eyes were ubiquitous as soon as complex life enters the fossil record
7:30 The man in the middle of the photo is missing his right hand.
I think he is John Wesley Powell. Look him up on Wikipedia... he has a very interesting life. He has many things named after him like Lake Powell.
@@beachbum200009 I used to go houseboating on lake Powell, back before it developed it's infamous bathtub ring. The side canyons are a dream to explore. But the wind can get a bit nasty on the lake. As a kid I remember one storm blew us out of the cove we had picked for the night.
Finally a new episode! I have watched all 28 former episodes (this is No. 29) - they are the best towards Earth's history I have ever found. Please continue this series through the periods of Earth's history until (and including) the Kainozoic. This series is such a treasure of knowledge, it should be on the curriculum of schools or even universities.
this channel is highly underrated. The quality is up there with the best!
Great UA-cam Channel as well as Video with great analysis, voice, animation & feelings of reality. We are always with you plz upload videos on regular basis, you waited us long. Thank You Very Much 😊
More from this channel, please!
New-fund-lund, bare emphasis on "new."
Never new-FOUND-land.
@@HedonisticPuritan-mp6xv then you're clearly not Canadian.
Brazilian geologist here. Thanks!
It is a masterpiece!
These works are amazing! So much better than anything on mainstream TV. In fact, the last great series (on terrestrial TV) of this type was Aubrey Manning's Earth Story, over a quarter of a century ago!
Imagine being the poor bastard who goes back in time to the cambrian just to see the life there for themself, only to realize, "Oops! All trilobites."
Got to admit, I’d love that.
Of all creatures that have ever existed on Earth, my favourite is the Trilobites, with Hallucigenia coming a close second.
When I hear there is no sewing system in the USA, I'm amazed! 😱
What kind of coutry is this?
Again, asking for a way to support you besides clicking ad links and such! If you get a Patreon or something with ad-free videos, I'd subscribe in a heartbeat! Thank you so much for the work you do: these videos, these channels, are hands down my favorite on UA-cam!
Why do you want ad free videos? Would you watch or just listen to them?
@@olivergilpin I hate ads, with a passion and I do both.
Leila Battison is the best writer on this channel by far!! I hope she writes more for hotu!!
Many thanks, Leila! Once again, so superb. And all without much mention of the Burgess Shale or "Wonderful Life."
One of the best channels out there. Keep up the incredible work, good science man
At last ! I cannot thank you enough for this series, it is clearly my favorite from all those you do
This is truly an amazing world we live in and I still can’t get it in my head how old it is and at one point why did the Dinosaurs live here and no humans 🫣🫢🧐😳👊🏻❤️
A gem of an episode, one to watch more than once!
This is such a great channel, peaceful and informative. You really take me on a journey through the Earths story
I use my tablet as my alarm so in the morning when it tells me to get my butt outta bed i always see the new notifications , the drawback is i saw yours and it'll be at least twelve hours before I'll get to sit back and enjoy it ! Thanks guys !
Jokes aside, I love his content.
I sleep to it almost every night.
This, Universe, and Humankind help bring me peace. Thank you 🙏🏻
10:47 “Finally, Australia shouldered into the continental scrum.” Because what else would you expect from Australia? 🏉
Thank you guys for yet another interesting video! I told my wife about the urine problem in New England, and her facial expression was hilarious.
God be with you out there, everybody. ✝️ :)
A fascinating documentary on this most interesting time in the early history of complex life. This is such a brilliant channel, with great topics that are covered in detail yet are presented in a highly engaging manner.
Bedtime sorted 😴. Thanks in advance for another enjoyable and thought-provoking video.
Excellent content-not that unusual these days, still much appreciated.
Adept narration-much rarer. Even more appreciated.
Nice lead in to the sponsor 😉 it's always pleasant to get a joke with the pitch. Fantastic video as usual, I watch them all many times and my kids like them too. We listen to them before bed
It's so nice to rest and learn together at the end of the day 🥰
Just when I thought that you could do no better, you bring out a new video and raise the bar ever higher. Well done!
It always makes my day when one of these videos comes out.
this video is so inspiring and scientifically well- founded! Thanks for having made it
Fascinating. Despite my interest in Biology & Geology going back decades, there seems always something new to learn. Thank you, once again, for not dumbing-down the content matter in the quest to keep it entertaining.
Fantastic as always. Thanks
Another remarkable episode amongst many others in your various series. Quenches a thirst for knowledge. Well done.
Thanks again for one of the best quality content on You-Tube.
"Helicoplacoids look like a towel that's been wrung-out to dry...'" - I think I've truly found my Cambrian spirit animal now.
I just love your work. So great to have new material to enjoy! Btw, my all time favorite has been The Boring Billion. Thank you for being uniquely awesome!
Climate change doesn't necessarily correlate to sea level rise if there are no ice caps already
I think this channel is my favorite, absolutely great videos every time!
It has been shown that the Cambrian is not the earliest period of fossils. That honor goes to the Archean.
Just like a fast radio burst, this channel's videos are worth waiting for. . . I love this channel! My joy is boundless. There IS a Troll Research Station!
Brilliant, as usual; thank you.
Totally worth the 5 month wait since the last instalment of this incredible series... quality > quantity.
Oh yeah! Feel like I've waited soooo long for this. Awesomeness
It's not that 'life is lazy' and won't expend energy, it that in natural selection every tiny advantage helps survival.
Have watched this thrice over now; even among your extraordinary channels History of Earth is something else
I got notification from this channel & honestly it's like winning the lottery thank you
I love documentaries about warm ocean soup
This was exceptional and I learned so much! Thank you!
Another fantastic video!
Good to see Wales referenced, most people don't know the country even exists.
I know of it because of The Welsh Viking.
Just finished watching!
It's always a great day for some history!
Diversity of units would earn you a thumbs up.
Newfoundland is pronounced Newfin-land
New finland 🇫🇮🇫🇮🇫🇮🇫🇮🇫🇮
Terrific! A well-told tale of the start of multicellular life.
I absolutely Love these videos about earths geologic history 😊👍 Even more then the history of the univers videos of yours, tho I realy enjoy those too.
Such a facinating existential subject.
Troll research station? Do I keep hearing that correctly? Lol
Thats correct. Our norwegian king even joked on a interview that the station was named after the queen 😄
@trifemaster 😁
There's something funny yet depressing about the idea that the evosystem of Cape Cod is literally being pissed to death
Excellant audio level and mic work.
