I want a video in this series where the tangents just keep getting farther and farther from the main topic, and it just goes on for hours and never resolves.
I could listen to this guy read the phonebook
More tangents than a trig class.
And then we moved on to the Crusades...I was like, these people are geniuses.
So do I
@Eastern fence Lizard You sound like a brilliant person. Umm, how do we get rid of politicians? There are politicians even in an absolute dictatorship. We just don't call them politicians. Kinda like the Kevin McCarthys and Moscow Mitchs that would have evolved in the second, but perpetual, trump administration.
I knew an old gentleman who had worked in a quarry in South Wales. He told me of the time when they blasted a rock face and couldn’t believe their eyes. The entire quarry face was a fossilised forest of ancient trees some fifty to sixty feet tall and so tightly packed together they were like grass.
Damn! So forests were more like a solid block of pure tree.
@@PyrusFlameborn Maybe. Or they were packed tightly after being knocked down by a flood or volcanic blast, covered over and fossilized in that way. Over time the Earth shifts and makes them appear to be standing upright.
Who knows.
@@BellumCarroll similar to bone beds when animals died en masse
Wow. It's possible those trees didn't need the same amount of space/ sunlight as ours today. Look at the diverse and rare capabilities of plants and animals now. Thanks for sharing, and I'd love to know what happened to all those fossils.
Smells the result of volcanism. Happens a lot on geological time scales.
The narrator David Kelly has such a calming voice, when I play these videos I sleep like a baby.
I watch it the first time awake, then I play old videos before bed, very calming indeed.
@@thezaher Yeah, I do tend to like to rewatch/listen to more familiar material when actually expecting
to sleep. If I'm learning too much new I'll tend to stay up. Though sometimes that's OK if body tires out before I'm sleepy. :)
@@OllamhDrab another bedtime favorite of mine is PBS Space Time.
The episode about how the universe will end is really soothing 😅
Check out his brother's channel, History Time, his name's Pete Kelly. Very similar voice, very good quality material!
I never know whether, for the creator, thats actually a compliment or not. 'Your content puts me to sleep', doesn't sound like a compliment. Lmao
Conventional wisdom: you must have your intro within the first few minutes of your video.
History of the Earth: Hold my beer...
Conventional wisdom gave us Love Island & the Transformers Movies.
@@HistoryTime Very true! I believe in thinking outside the box when necessary. That's how a lot of progress has happened.
@@HistoryTime Don’t forget the Twilight saga movies.
This intro could have been even longer had they included the section of history where micro organisms used photosynthesis before plants even existed on land. (they barely mention it later in the vid)
This was the prettiest, non-annoying advertisement for renewables ever :)
It was pretty annoying
@@smorrow your comment is annoying
Love this series. Wanna add: the reason we have these huge coal deposits from the Carboniferous is that fungi and bacteria took a long time to evolve the enzymes needed to break down cellulose. So not much chance was needed to fossilize early trees, hence huge coal deposits today.
Also these trees were in swamps and therefore fell into water when they died. The sediments then saved these trees from being consumed and they sedimented instead. And as soon as they had dried too much, they were not eatable anymore.
Both wrong. Jesus wanted to make coal. Boom, it has all been explained no questions please
@@DG-iw3ywevidence?
@@DG-iw3yw they just described exactly how Jesus made the coal
There was another form of photosynthesis that developped before the one that dominates today. Its color is purple, and it processes sulphur compounds instead of oxygen. Had chlorophyll not evolved to outcompete it, life on Earth would also have developped in a very different, yet possibly just as diverse way.
Nice observation! However, oxygenic photosynthesis uses water as a source of electrons and hydrogen, a much more common raw material than sulphur compounds. If it was the dominant form of photosynthesis, life would be very different indeed, but I don't think it would be just as diverse. There wouldn't be enough resources to power ecosystems like the ones we have today.
ive never heard of sulfur photosynthesis, where did u hear this?
@@xX_wiLLiam_Xx The episode about the oxidation event.
@@Pfh3dk there wouldn't be enough here on earth. But in an alien environment there might be. Venus. Even chemical clouds in space.
Chemosynthesis?
I have been an Earth Scientist for about a decade. I've prepared very nice presentations and lessons on the history of the Earth... These folks have done such an amazing and professional job, and utterly without errors or misconceptions being delivered to the audience.
Fantastic!
it feels like we're slowly edging towards the final episode: "How the Entire History of the Earth culminated in Country Music"... Apart from that another great 35 minutes in the history of my life, thank you!
i'll watch that right after i go deaf
Ha! :D I can kinda see how that would work...kinda like the "How the Universe Works" episode called "How the Universe Built Your Car" or something like that. Like:
--We learn how trees evolved from earlier plantlike things, including the trees harvested for the kind of wood used for hollow-body guitars
--We learn how the animals evolved whose guts were originally used to make the strings, and then how we made the strings out of polymers that came from oil that was made from very old dead microorganisms
--And last but not least, we learn how proto-humans' love of sound and rhythm evolved into music, and from there, The History of Folk Music until we hit country. Ta-da!
It'd take more than one episode, but I could see how it would work. :P
That would be wild.
Brilliant work - but I'd have to argue with your description of the chemotrophic Archean world as COLORLESS! Those mineral acid pools all heavily laced with numerous different ionic minerals would have caused a rainbow shower of brilliant colors that changed with the Ph and local chemical brew, perhaps even seasonally, which would easily rival if not outdo our emerald seas, summer's greens and fall's reds.
Would have been better to have shown the ancient world in more art than the same one black and white drawing and stock footage of the Catskills.
Just a small correction: Pangaea hadn't formed yet in the late Devonian, there were still the two major continents of Euramerica and Gondwana (as well as a few smaller ones).
@@Dragrath1 man can just about predict the weather for a few days weeks and maybe vaguely for months
Where you there during these periods millions of years ago
U think that coal oil and gas was made from vast amounts of vegetation quickly laid down and cut off from oxygen then layered over many times compressed
@@markmitchell450 It's much easier to see what has come before, since plenty of evidence is left behind. Our skill at predicting the future should hold no bearing on our ability to research the past.
As for the preservation of carbon, the reason the carbon has stayed locked within the plant material and later turned to coal is that, at the time, few if any organisms could break down woody tissues to release the trapped carbon. Wood didn't rot. For millions of years.
Just a heads up. Coal did not form because trees got buried. All coal formed during the same period because there was nothing that could break down the deadwood of those first ancient trees. It would be some time before fungi adapted to break down lignin which makes up wood. So dead wood would pile up on forest floors with nothing to break it down. It would gradually get buried and crushed. Coal no longer forms now because fungi are now very efficient at breaking down fallen trees.
So once we use up our fossil fuel, that's it. There will never be fossil fuel again. This will happen because there is a finite amount.
coal can still form, but it would take the right environment where the fungi can't survive, such as a peat bog.
He messed up his astrophysics too, when it came to how greenhouse gasses worked and talked about how Venus got how it was.
I love the sweeping majesty of this series’s narrative, it’s so all-encompassing and yet so accessible. Continues to be required watching each time a new episode comes out.
Yes . Writing and narration are superb .!
can't argue with that
I get the distinct feeling, that once a life has been established, it always finds a way. One way, or another
fines a way 2 do wt?
@@The1stHomosapien survive, you cretin.
@@eccremocarpusscaber5159 umm, no, it is fragile and many species can become extinct easily.
@sprock how can a point be a circle?
I, uh, agree.
23:20 For the actual subject
Shhhhhh! They'll make it a self-imposed challenge and then we'll never again get to the point. :P I do like the digression (er... pregression?), but the video needs a different name.
Thank you!
Thanks. I actually quit watching before that came up. Poor title for this one … 🇨🇦🖖🏻🇨🇦
Yeah and for those with limited attention span. ! ie. The 53 likes
you got . I'm sorry all.knowledge cannot be compressed into tiny
bite sized chunks to suit you .
Maybe stick to Cartoon Channel
in future...?
Really well done! You guys rock. I am SO glad we non college people have access to this stuff! We may have had to work instead of study but we still have that intense curiosity that you help satisfy!
Halfway through this video and he's still not talking about what the earth would be like without photosynthesis.
Well there sure wasn't a lot to say about it. Everything is basically cave slime. Hard to make a half hour presentation around that, haha.
@@umbrascitor2079 oh I'm sure there is plenty who could go on all day about cave slime
Yes.
@@umbrascitor2079 Ummmm, cave slimeeeeee....
This guy could have a presentation about clowns and I would be glued to the screen.
And I don't even like clowns
Alternate video title:
What would the Earth be like with Photosynthesis?
seriously....
Lmao
for real
That intro deserve to be an episode on its own.
"Lobsters are older than trees" -Canadian frog professor
This is true. So? Trees are older than Canadian frog professors.
@@Egilhelmson - Nah, Canadian frog professors are immortal, but used to be English back in the day...
Which trees!
Fleur-de-lis are older than any Frog Professor .
@@sonnythecuckoobird8645 Tabernouche! Maudit anglais!
6:12 Vast tracts of swampy land? She's got huge . . . tracts of land! We live in a bloody swamp! We need all the land we can get!
No singing!
A millipede is a myriapod not an insect as implied in this video. They both, however, belong to the largest group of animals on earth, the arthropods.
Wrong. They is all bugs.
So you're telling me that Dudley wouldn't be the post industrial s-hole that it is today if it wasn't for photosynthesis?
Lmao. I'm from Kidderminster and even I think Dudley is a bloody shite hole.
Dudley is the crowning point of Creation. !
Commenting on a video within minutes of it being posted and claiming to know more about the video than anyone else is simply online heroics.
I find that hilarious too. Comment warriors just want their vast knowledge and opinions at the top.
Btw i commented before it was even posted
😝 well said.
@@the_monkeypox_commander6603 😂
Must be Donald Trump.
Think that there's a big clue in the title to probably work it all out
This series has been fantastic to watch. Such good quality, excellent narration. Really enjoying it. I hope you do an episode on the Ediacaran period and the unique fauna of that time. There is not much on RUclips about it, and it's such a fascinating period.
This is one of my favorite channels on YT. Please, keep making videos. We need more! And thank you!
Hey I actually use your videos to sleep. It's so great and I learn so many things since I repeat or go back to the last thing I remember before falling asleep.
My only suggestion would be, if possible, is torefrain from changing the volume in between the narration. I've had some nights where I had to listen to something else becuase the volume change was a bit jarring.
Thank you for the great videos and keep it up!
I’m addicted to these videos. Can’t get enough lol
The way you give science, and earth's story, a soul, is truly beautiful. Thank you!
I absolutely love your channel! Not only is this topic facinating, but your calm voice and well selected soundtrack create a beautiful experience. I must admit, it is my favourite thing to hear while falling asleep. Respect!
Ecological diversity at hydro-thermal vents is incredible with large animals taking advantage of the food source, including vast fields of clams, octopuses, crustaceans and worms, even some fish are able to inhabit these depths and take advantage of this food source. This environment has complex ecological webs as complex, if not more then the majority of the ocean, due to the abundance of primary production. So while life would be very basic and rate, it would be able still in these environments to maintain similar ecological similarities.
They had so many good intro ideas they just decided to do all of them
Leila Battison's work is excellent. The writing of these documentaries is always a source of delight!
Agree ! The Writer is too often forgotten . Yes, the visual / technical aspects and the narration are superb . But without the right words to accompany them the effect would be less impressive .
Cool documentary, well worth a watch. One critique though. Took waaaaay too long to get to the subject matter IMO.
Thanks for these videos. I've watched a few you've posted and they are uniformly high quality. I've enjoyed them immensely.
another awesome video! i'm super excited for a video on the carboniferous, nothing is more exciting than giant arthropods and adorable temnospondyls ❤️
Took 24 minutes to get to "A world without photosynthesis". Was so close to leaving the video before you even got to the point, really felt like you never would
Short attention span ? Stick to watching Loony Toons ..!
@@2msvalkyrie529 wow you really showed me
Try expanding your attention span ? Or stick to watching Disney channel ??
Loved the video. Did not find the music especially fitting for the part near 12.30
Another lovely video! I could watch your videos for hours! Thank you so much for posting.
Very informative, connecting recent findings nicely, and kudos for links to the work.
Keep it going, these videos are amazing!
Being from the coal fields of Western KY, the carboniferous period has always fascinated me. We have Mississippian limestone and sandstone along the escarpments around it too. Full of fossils. Ammonites, Blastoids, bivalve shellfish, leptodendrons, etc.... All from a time before the dinosaurs even thought about walking the earth. So much time....and events between then and now. Fodder for non-stop thought and imagination.
Muhlenberg county...
Love your work, mate. Keep it up, your videos are not only interesting but entertaining too.
Well laid out, informative, and insightful…Agreed about the narration. Very well done, along with the graphics and music. Top notch stuff. Thanks 👍
Love the mix of video and colorful artwork!
Same thing here! I usually play one of their shorter video in the evening and peacefully fall asleep 5 to 10 minutes in :-D.
His soothing voice is the best recipe for a good night sleep. Then I of course re-watch the video in the morning.
However, this channel is not meant for sleeping, their documentaries are wonderfully made, I absolutely love them and this is definitely one of the best channels on RUclips.
Keep up the good work!
This is my favourite Channel on all of RUclips. Everything is golden, truly mind expanding content 🙌💪
This channel needs more subs
i like your presentation of the topics.
thank you for not screaming at us in the intro.
100 points in my yelp review for sure!
This was a joy to watch! Way better than tv. Keep up the good work. You deserve way more subscriber's.
Great to see this fantastic channel growing in popularity.
Excellent, as always, thank you :)
I absolutely love this channel, great content brilliantly delivered!
I love these videos! Please keep’m coming!
Loved how the topic was introduced well into the video, I was already hooked
Another great video, this channel is amazing.
This art work is mind blowing!!!!! Great video 👍👍
Yet another outstanding video 👏
This is perhaps the most convincing case for Solar Energy I've seen. Great job once gain for yet another well-researched and brilliantly narrated documentary.
Think plants had us beat on that one. Or really just, all life on this earth. The sheer fact that every single animal on earth is powered by social energy should have been clue enough.
Except for the cave part where is literally no solar energy for millions of years :)
@@Tisicajedna but for that he explained that chemical resources are finite and made evolution very limited. Without photosynthesis life on Earth would have remained primitive
So close to 100k! Such a good channel. Thanks for many hrs of amazing content 🤣😁
The music... I can't take how it swells in and out, even between words sometimes. I just can't get through this. It ruins the whole thing.
Always a good day when you guys upload, love this channel
I never realized that I am really lucky to live near the Catskills.
You would be luckier if you lived by the Finger Lakes, Lake Titicaca or the Bloughengoe Valley
What a great video, this channel is incredible
The history of the world without photosynthesis took 5 minutes of the film, because that was the story of Movile Cave in Romania. The authors did not have enough imagination for more. Me too.
Will you be uploading your version
of Earth History soon. ?
We can't wait. ! It's bound to be
much better than this ...?
2:40 - "large animal life was largely confined" - just love this "barrel organ" style of narration...
Super great channel!!
Always makes me smile when i see an upload from you guys.
The actual topic of the video begins at 23:12
EVERYTHING is connected !!
Try to grasp that fact .! I know it's difficult but with a bit of effort you
MIGHT get there.?
This feels like I am listen to a science book on audible rather than a RUclips video. This is not a criticism as I love the ground working/scene setting. Possibly not necessarily for an online video but gratefully received. This feels like a chapter of a book that I would happily buy on the subject....
I'm addicted to this channel... I can't stop watching...
great episode!
I'm sorry for your loss. I absolutely love your videos.
Cool man.watched you lot in a stream the other day , was hoping for some good one's. here they are.
Great and amazing video!
It feels like this should have been three different episodes. Parts 1 and 2 aren't really related to the title of the video
That cave is amazing. Life is awesome. Enjoying being a part of it.
Today is a good day. Subbed to History of the Earth :) You rock!
Video starts at 23:21
Leila, nice job .... well done!
Best vid to fall asleep with. Tanks mate.
Fascinating - puts mainstream commercial history documentaries to shame. Bravo to the creators!
"Our entire atmosphere seen from space is a product of plant life. Whether this is intelligent or not remains to be seen."
...yeah, the jury is still out on that one.
Thank goodness that it's flat, so it can be easily seen by extraterrestrials
Excellent video
excellent video!
Loved it!
It's almost a crime that this is free. These are incredible videos
More than halfway through, and it's like a kid giving a report on something he wasn't ready for; hasn't gotten to the point, seemingly totally forgot what it was, so just bs's about other stuff he knows
23:11 into the video, our lost lad remembers...ah, right
Let me just say, with the plethora of legitimately good scientific content out there, yall have done an incredible job. I only found this channel a few weeks ago, but it's quickly become one of my most recommended science related channels. Right up there with Kurtz, Isaac Arthur, PBS ST, and Facts in Motion...very well done, keep it up.
yall too
The music was just waaaaay too busy in this one, sorry. Too many different styles, and it's so loud that it's hard to focus on what you're saying.
This was good! :)
I've had this weird warm feeling for this fictitious alien civilisation discovering life :p
Thank wou for the great narration !
I love this series.
This is got to be one of the better RUclips channels!
The usual instant click and like. As always top notch quality. Thanks a lot for another excellent video...
I remember reading an article about how the first photosynthesers used light produced by ancient thermal vents. As they do produce a dim glow
It was a very good video I learned a lot from a thank you very much and have a great day
I like how you finally got to your intro video 10 minutes in.
23:00
That's where it actually starts the part about what if photosynthesis never happened!!!
Really ? Did you have something better to do ? Sorry to waste your valuable time.
@@2msvalkyrie529 uh... Yes, actually I did. These are subjects I'm generally studying. I was looking specifically for the information on photosynthesis. I too have been studying the history of the earth, but mostly human prehistory.
For a lot of people the whole video will be very interesting, but not everyone has 23 extra minutes when seeking information. For some people this video isn't something they're going to sit back and watch, but something they're looking through for particular takes on information. Not all of us are people who just sit around staring at screens all day, or at least want to any more than they have to! :)
beautiful
