- You're not everybody! Now sit here and take your sulphur, my procario-baby-boy...
That's personality.

I love how we think we are the dominant species, yet there is a creature that holds the evolutionary foundation for our existance.
We stand on the shoulders of giants
i love how some of us think we unnaturally alter the environment, meanwhile these guys accidently set life on fire some time ago
We are not THE dominant species. We are CURRENTLY the dominant species.
@Saraneth the Binder If science went by opinion, it would be no different from religion.
Dominant in which sense though? Numbers wise? Occupying the most land? That term is too general and vast for biology to be used in just one sense of the word.
This is why I sort of agree with the OP, specifically the "think" part. We think so much that we forget to look at things in ways other than what we think.
omg i LOVED the transition between the rotating shot of oscillatoria and the banded iron formations. a delightful surprise!
JTTM is full of these things, support them on patreon!

This is one of the more beautiful science channels.. their microcinematography skills are unparalleled

Thx rotifer, hope you are well.
That was such a Buzz Feed comment!
Stop by for a feast on my Cyanobacteria, Mr. Rotifer, sir
@@kinglyzard I’ll bring the algae!
Phytoplankton is the same as algae
Anaerobic bacteria: I'm dying, you're killing me!
Cyanobacteria: Oh.
Anaerobic bacteria: No, it's O2.
which is toxic to some bacteria I'm guessing or assuming
Moses Jonson well toxic to everything lol
@@HShango Oxygen is one of the reasons we "age", or more accurately, oxidize.
@@HShango Some anaerobic bacteria are more specifically known as "obligate anaerobes". This means they need an anaerobic environment, one without any oxygen, in order to survive. So yes, oxygen is toxic obligate anaerobes. In fact, use of pure O2 has been used to treat certain bacterial infections from obligate anaerobes, which can happen in deep puncture wounds like a tetanus infection from stepping on a nail.
@@Bernholesurfer Master Therion's joke is making me feel "oxidized"

not anymore there's a blanket!♪♪♪
YES!!!! I thought the exact same thing!!!
@@nerysghemor5781 Now you can eat sunlight!
@@akashiluddi Well they were already "eating" sunlight below the surface of the water long before then the big change was the whole ability to live on that silica rich floating raft of lighter weight rock we call continents. Of course that would take a few billion years but you got to start somewhere.

@@Dragrath1 Bill wurtz is good stuff amirite?
There's a joke in here about this channel being a breath of fresh air.. but I'm not gonna make it.
Just like most of the anaerobes.
Then I'm not going to laugh at it.

I'm not gonna like and comment.
I reallyl like the visual scale at the bottom right corner.
Grosse Fée i think they only recently added that!
@@katyungodly Yeah! It's a brand new thing that I was waiting for since a long time. I've asked for it few times as 200X is not very evocative of the size as it will change a lot if you watch on a cell phone or a on a big tv screen. Now we can get how big microbes are!
I wish you'd talked about how oxygen took a long time to accumulate in the seas because as it was produced it reacted with carbon or free floating iron molecules or any of the things oxygen freely reacts to and was sequestered. It took fifty million years or so for that process reached equilibrium. After all, mid ocean vents or unwater volcanoes were continually adding more things to oxidize. Once everything was oxidized, finally, molecular oxygen started to accumulate in the oceans and leak out a bit into the atmosphere. As soon as it did it immediately formed oxides and was gone. Every rock surface, atmospheric methane, everything that could oxidize on land or in the atmosphere had to oxidize before free oxygen could begin to accumulate. That took a long time and you didn't mention any of it!
Man: I can change the chemistry of the atmosphere and change the climate.
Cyanobacterium: Hold my chlorophyll.
Well we are tinkering with them to try and clean up our mess so maybe we will fix it with a little genetic engineering. The defining trait of humanity over everything else is advanced technology and the first species to literally intentionally override natural selection on a scale never seen before (plants, pandas, animals, bacteria, beer, ...). We are supposed to be able to look at the big picture but with our lifespans being only 80-120 years people are still very shortsighted as many just kick the can down the road which is a bad idea.
@@riakata be careful because they could turn this planet into a snowball again
@@riakata We poluted the hell out of this planet when we had less technology in the plistocene. Human CO2 emissions back then whent through the roof.
Luckily, as we avanced technologicaly our CO2 emissions came down as well as every other polutant, especially when we invented cars, planes and computers.
Or was it the other way around?
A scientist puts his personal preferences and beliefs asside and looks at the data. There is a clear correlation between technological progress and environmental destruction in the last 10.000 years and especially the last 200 years but most people don't have the intelectual courage to admit this.
No, i'm not saying we should go back to the stone age (But i know i'm gonna be accused of that because it's a classical emotional response, a thought stoper). But if we are not going to be honest about this then we don't stand a chance to solve our environmental problems.

CO2 is not a pollutant, it’s the gas of life. Greenhouse farmers are adding CO2 (600-800 ppm) for better growth.
However, I do agree that humans do pollute Mother Earth in a ridiculous paste. A nice example can be found here on YT, search for words toxiest river or toxic farmed salmon. There is micro plastic in plankton today. The list can go on for ever.
The hunt for global economical growth is the real killer.
Search for how many percent CO2 there is in the atmosphere, then compare that with water vapour (that is a greenhouse gas) and make some conclusions.
Cheers
@@chukwow5738 All your myths have been adressed multiple times, so much so that we just compiled a list of it as to not have to write the same thing over and over again. Here is the list:
skepticalscience.com/argument.php
"CO2 is not a pollutant, it’s the gas of life. Greenhouse farmers are adding CO2 (600-800 ppm) for better growth. " see nº42 and 43 on that list.
"Search for how many percent CO2 there is in the atmosphere, then compare that with water vapour (that is a greenhouse gas) and make some conclusions." see nº 36 and nº77.
Tiny plant spaghettis! ♥️
Except they aren't plants!
Were eating that make you a non vegan?
*Also a little known fact, they're magically delicious!*
Actually they carry hepatotoxins and neurotoxins. They are called blue green algae but are actually bacteria and can be dangerous, DO NOT CONSUME and avoid swimming in a lake where they arr found.
@@artemisqueen2 Exactly.
You’re thinking of actual algae that people harvest for consumption (which is a plant). Blue green “algae” is a bacteria.
yep they are extermely dangerous, do not buy the stuff. They are marketing it as a nutrious supplement. Most companies do NOT follow proper guidelines and have found to contain cyntoxin levels. Researchers also they block b12 receptor sites preventing cells from in taking b12 causing deficiencies.
Yall didn't see that op is a Rotifer?
6:54- "Hey, guys! Can I be in the shot, too? Can I? Uh... no? Okay, I'll, uh... I'll leave, then... sorry...."
they're more than just delicious ...
they're the most nutrient dense and averrable food we have..
easily the answer to ALLL human malnutrition situations..
Lol 😂
Pretty wild that an apocalypse paved the way for us...in fact many.
Anyway, thanks little buddies!
Welcome to the post-apocalyptic world we live in.
Several times over really.
At least once due to a massive rock hitting the earth.
Around 11 times due to "flood basalts" which is a nice way of saying that suddenly large areas of land became lava fields, the sun was blocked by ash, and acid rain fell all over the planet due to enormous quantities of sulfur and CO2 emitted into the air.
Around 12 times due to the sea-level falling, concentrating the oceanic brine and uncovering coral reefs and continental shelves. These could be due to volcanism, or ice-ages?
Some of these times it seems to be related to global warming (from volcanic gasses or maybe methane clathrates) reducing the solubility of oxygen and CO2.
So depending on how you count it is somewhere between post-post-post-post-post-apocalyptic and post-post-post-post-post-post-post-post-post-post-post-post-apocalyptic.
Many apocalypses have... and if history repeats itself, we will pave the way for something else.
@@abramthiessen8749 If some humans would study the types of extinction events that have happened on the earth so repeatedly, and over such a large period of time, they may realize that we are in a small window of peace, on a violent earth that has literally wiped out 99% of it's life, many times over. Maybe then people wouldn't be so quick to release so much C02 in the atmosphere.
@@rcchristian2 Hey, we need to correct all the damage those cyanos did!
@@Tfin hahahaha - that's funny :) I think we are hahaha - great comment Tfin :)
This video is now one of my favorites. Its not only illustrative of your weekly work, but also you try to explain these great biology facts, papers, and research... A real soothing and memorable experience. Keep it up!
I have never missed an episode.
I have never been disappointed.
I am NEVER unsubscribing.
I love this channel.
As others have described, iron "captured" a lot of the oxygen (forming the banded iron formations) prior to atmospheric oxygen levels rising. One reason why multicellularity could have developed is that, by being multicellular, an organism could more effectively "protect" itself from toxic levels of oxygen. (A great book that describes these processes is, "Oxygen: the Molecule that Made the World", by Dr Nick Lane. Book is still remarkably relevant and current, in spite of being published in 2002).
That was an incredible book! I learned a lot from it.
Great now whenever I hear the song it's the end of the world as we know it I'm going to picture cyanobacteria singing to other microscopic organisms as they slowly die
"Country roads, take me hoooooome, to the plaaaaaaace, where I belooooooooonnngg! west virginiaaaaaa, mountain mommaaaaaaaaa... take me hooooooommmeee, country roooaddds!"
Those lines of Oscillatoria are mesmerizing
7:07 these two branches: *are moving in the opposite direction*
The rest: why ar u runing
I love every single one of your episodes, but I think this one might be your best yet.
Came here because ‘Crime pays but botany doesn’t”
Same
Another great channel!

This might be the prettiest and most well shot video so far. I love you guys, keep up the good work!
Absolutely love what y'all are doing. Presenting this vast amount of knowledge in such high quality which is absolutely free is unbelievable.
For people like me who love learning new things such platforms are heaven.
Thank you🙏
"You do not need to be complicated to be important." Okay I'm crying? That's so motivational.
Thank you guys. I have taught my grand Cyanobacteria when they were around three hrs of age. So I am very pleased to come across this video and forwarded it to them at this very special time of Covid -19 period. My grand children who are now 8-4 yrs olde will digest this information even more than ever before. So I thank you from my heart. For such a wonderful video. I have also FB this video. With love and respect and peace.
I enjoyed this episode because I have always really loved learning about the GOE, very interesting topic. But my favorite part by far was the microscopy work- SO beautiful!! This James guy has some major talent!
always beautiful! The photography is stunning plus, I learn something every time
This may be the best one yet. All of the shots are just amazing.
been watching from episode one and been loving it ever since. keep up the great videos!
This is one of the best episode of Journey to the Microcosmos yet, There's just this sense of wonderment and awe that makes you really think. An idea of history and scale that really comes over you.
The editing transitions on this one are next level 👌🏽 props to the editor and the people filming this for hours
This is probably my favorite channel atm. Good stuff.
Thanks for helping out Steve!
Never miss these vids. Great series guys!
The description feels like a guided meditation. I'm loving this.
Gah your videos are just so engaging and calm !!! This channel sparked my interest for micro organisms, and now I wanna get a good microscope just to look at them!!
Thank you so very much for linking the music 🙌🏽 a lot of big channels don’t do that
This video is as grand as all the previous ones, Thanks for improving our Mondays!
(P.S. the music, while delightful, did compete just a bit today with hearing the narration).
I cried haha... So grateful to be alive, being here to watch this video, early in the morning, tired and extremely happy to be here.
The more I learn about microorganisms, the more amazed I am by life in general, as well as the ability and maybe luck that any complex organisms exist at all. Absolutely amazing.
This video is so high quality like oh my gosh you just earned yourself a subscriber
I nearly shed tears at the end. I hope we leave this place better than we found it.
I love the shot at 4:27! The Aphanizomenon is nicely framed to appreciate its intricacies, and in the background are happy looking spinny-ball-things!
Our story is so amazing, thank you for telling us this part of it.
Love your channel, never imagined this could be so intriguing.
Thanks to Crime Pays But Botany Doesn’t for directing me to this channel; marvellous content, and duly subscribed.
Global Gardener same here
well done!! this channel is great
What a fantastic and inspiring channel!!!! Great work to you and your team. When I was a kid, the only story I heard of Cyanobacteria was that they were poisoning our water with their algae blooms. So I dismissed them as a pest. Recently, I have been studying desert soil crusts and I am so facisnated by how they are so important to their ecosystem. They are the pioneer species that allows almost all desert life to thrive. After seeing this, I realize that my understanding of them is just the tip of the iceberg!! Thank you for going into the philosophical aspects of biology in this video! It’s really exciting!!
the visual transitions are really nice on this one :)
Best channel on biology so far! along with the microscopic footage the narration is amazing too.
I love your voice. It gives me chill, relaxing state. 🥰
Captivating and fascinating, as habitual for this channel. Congrats.
You guys should make an in-depth video on how to prepare slides to look at the micro cosmos. And how to focus/use the microscope correctly.
Oh wow, the transition from Nostoc to Archean Earth, and the transition from Oscillatoria to the banded iron formations, just- ::chef's kiss::
Thank´s for another amazing video!
That was great, clear and not giddy.
I love these videos and this channel. I loved the explanation of the theorie.
This channel calms me a lot
HANK! You the MAN!!! love these

I really love your material. It's amazing !!!!!!!
Cyanobacteria are prevalent with Blue-Green Algae which are everywhere. They bloom together throughout the weather patterns of the US. Making toxic, Blue-Green algae almost present at the same time for warmer months.
The science here is one of the most important events in Earth's history of life, and so full of mystery and wonder I defy anyone to dig into it and not have their breath taken away. (As opposed to having their breath given to them, which is what it also did.) But - and this is what I love about this channel, this is so beautifully presented, one long abstract stained-glass piece leavened with moments of manic action and washed with that superb music. Such a treat. Thank you.
Thank you Patreons!!
This is truly beautiful! We owe everything to them ❤
I love your voice. So relaxing
i adore your soothing voice over

Brilliant match cuts in this episode!
A breathtaking tale...
I wish there was a livestream of the microcosmos. I could watch that all day.
Thanks Steve.
Great work🔬💚
Brilliant. Thank you.
What makes this guy's voice so ridiculously soothing
Anaerobic creatures: Noooo you can't just make oxygen you're gonna kill us all
Cyanobacteria: Haha funny air machine go whoooooosh
Enjoyed the video thanks
The visual comparison between the spherical algae Nostoc and the ancient earth is awesome!
If you unfocuse your eyes starting at 11:16 it gets very trippy and looks like universes spinning.
Love this channel
