FRUIT would NOT EXIST without CYANOBACTERIA

Fruits are the structures in flowering plants (Angiosperms) which contain seeds. They also have a symbiotic relationship with humans. We eat fruits and gain energy from their nutrients, while the plants gain from seed dispersal and increased populations due to agriculture.

But what do Cyanobacteria have to do with fruit? Well, it comes down to a process known as photosynthesis. All plants - and certainty all plants that produce fruit - create their energy through photosynthesis. However, plants cannot photosynthesize on their own. It's true, photosynthesis has NEVER been done by a plant all by itself. All photosynthesis that occurs in plants is actually being done by cyanobacterial endosymbionts, that is, Cyanobacteria that live inside of a plant and have a symbiotic relationship with it, producing literally all of its energy, and certainty the energy used to produce fruit.

You might be wondering, "why haven't I heard of these Cyanobacteria before that do 100% of a plant's photosynthesis?" Well, these Cyanobacteria go by another name when they're inside of a plant: Chloroplasts. A plant's most important organelle, Cyanobacteria are truly necessary for them to exist!

As such, you should VOTE FOR CYANOBACTERIA! Without Cyanobacteria, the subject of that other blog wouldn't even exist!

MAMMALS would NOT EXIST without Cyanobacteria

Mammals are a class of animals that has existed since the late Triassic or the middle Jurassic. These animals produce milk, have hair, and have some other attributes such as three middle ear bones and a neocortex (a region of the brain).

And, of course, mammals all breathe O2. This O2 was produced billions of years ago by none other than - and ONLY by - Cyanobacteria! Nearly all O2 on Earth has been produced by Cyanobacteria. Without Cyanobacteria, absolutely nothing that breathes O2 - and certainty mammals - would exist!

So, why do I say this?

How can you vote for something that identifies mammals over the reasons that mammals even exist in the first place!?

A vote for Cyanobacteria is a vote for Mammals! They wouldn't exist without us!

RATS would NOT EXIST without Cyanobacteria!

How can you advocate for this when rats, the subject of your entire blog, would NOT EXIST without Cyanobacteria!?

Rats, being animals, need atmospheric O2 to survive - or even to have evolved in the first place, since the ancestors of rats were also O2 breathers going back hundreds of millions of years! Almost all of this atmospheric O2 which rats know and love was produced by a single source: Cyanobacteria!

So, in a way, a vote for Cyanobacteria is also a vote for rats! Without the subject of this blog, the subject of yours would not exist.

Cyanobacteria, definitely. If not for Cyanobacteria, you wouldn't just be alone, but you would actually have never come into existence.

youre never alone. bacteria

Mine is "anoxic" *shudder*…

Good thing I never have to think about that anymore thanks to Cyanobacteria!

LEAST FAVORITE WORD???

tbh i cant think of a least favorite word that isnt like. genuinely harmful. i tend to like most words lol

[does-this-require-cyanobacteria]

re: the boltzmann brain thing there is a SIMILAR thought experiment called Last Thursdayism thats another one of those silly unserious "probably definitely not true but also you cant really Prove it isn't true" things that says "what if the universe just suddenly popped into existence last thursday, already in its modern state and with all of your past memories already in your brain?" just thought i would bring this one up because a Last Thursdayist universe WOULD have cyanobacteria in it... but whether other things would exist without it is kind of a funny question. like the cyanobacteria wouldnt have caused things to exist, because the things just popped into existence, but also the retroactive (is retroactive the right word here?) constructed history of the things DOES require that cyanobacteria would have been there, if the history did happen... what do you think? would a Last Thursdayist version of our world require cyanobacteria?

A LAST THURSDAYIST VERSION OF OUR WORLD would NOT EXIST without CYANOBACTERIA

So, in a Last Thursdayist version of our world, it is true that we can't factor the existence of atmospheric O2 into the equation of whether things require Cyanobacteria. Although in our world, Cyanobacteria caused all atmospheric O2 to exist (and thus also caused everything that uses that O2 to exist), in a Last Thursdayist version of our world, all of these things would have just spontaneously come into existence.

However, there are a lot of things on Earth which require Cyanobacteria to exist, even without atmospheric O2. For example, plants! Plants, even to this day, literally contain Cyanobacteria in the form of Chloroplasts. That's what they use to photosynthesize! Even if the Earth was created last Thursday, it would have devolved into utter chaos by today without these Cyanobacteria, and most macroscopic things would already be dead.

So, be thankful for Cyanobacteria, no matter how you think the universe came to be what it is today! Whether you're a brain in a box, whether you popped into existence last Thursday, whether G-d created you from clay, whether you evolved from LUCA, you should love Cyanobacteria all the same.

Because our world could not exist without them.

I think the next big gimmick blog should be a Cyanobacteria appreciation account run by a girl who goes to hashkama (:

Sometimes I wanna aggressively tell people off this site that tumblr isn't like they remember from 2015 but then I'm like wait the new big gimmick blog is an elvis impersonator acct run by a vriska kinnie tgirl. Maybe we haven't changed at all.

Would soup exist without Cyanobacteria?

(thank you for running this blog by the way, it is always educational and wonderful)

SOUP would NOT EXIST without Cyanobacteria!

Soup is generally defined as a mixture of edible materials in (usually hot) water. Although making soup is generally considered to be an activity only engaged in by Homo Sapiens, this is actually not the case! Other species of primates, such as Japanese Macaques and Chimpanzees, have actually been observed creating soup - even in the wild - with the use of hot springs as a source of warm water!

The common ancestor of us, Chimps, and Macaques (also the common ancestor of all the old-world monkeys) in whom the ability to make soup may have developed couldn't have existed without Cyanobacteria! All of these creatures breathe atmospheric O2, which would not exist without Cyanobacteria. Therefore, without Cyanobacteria, no soup-makers could have ever come into existence, and there would be no soup!

It's also worth noting that pretty much every soup ingredient wouldn't exist without Cyanobacteria. Unless your idea of a good soup is nutritional yeast, water, and salt, you'd need Cyanobacteria to help you make your dinner. Neither plants nor fungi and animals would exist without Cyanobacteria, which make up the backbone of every soup recipe I can think of!

could the Boltzmann brain exist without cyanobacteria?

The BOLTZMANN BRAIN COULD EXIST without CYANOBACTERIA

The Boltzmann Brain is a thought experiment that was done by Ludwig Boltzmann. The idea behind it is that since the universe will exist basically forever and since there are sometimes random fluctuations in the universe that bring things like particles in and out of existence (both of these things are true), that it is actually more likely that "you" are just a "brain in a vat" created by these fluctuations which will only exist for a split second (but was created with memories of existing for an entire lifetime) than it is that our entire universe has existed for 13.8 billion years in all of its complexity.

This argument is not meant to be taken seriously. It is only meant to point out the absurdity of other scientific theories about the origin of the universe or our consciousness.

However, as intentionally silly as the idea is, if the Boltzmann Brain were real, that would mean that everything actually exists WITHOUT Cyanobacteria since everything would actually have been created in a fraction of a second by your brain floating in space, then disappeared! B"H/Thank G-d that this probably isn't the case! What a terrifying though experiment!! I couldn't stand to imagine a world without Cyanobacteria, even if it was a silly theoretical one...

[does-this-require-cyanobacteria]

Scrolled through a lot of your blog and its super interesting! Anyways would emotion exist w/o cyanobacteria

EMOTION would NOT EXIST without Cyanobacteria

Well, defining emotion is kind of a tricky thing actually! A lot of definitions say that you have to have a limbic system (a specific brain structure which exists in Jawed vertebrates). However, it is always VERY important in biology to be wary of definitions which might be needlessly exclusive. I mean, who says you need a limbic system or even a brain to feel emotions? Octopodes don't have either and they seem to feel emotions too.

For the most part, however, it does seem like you do need to be an animal to feel emotions. Although it would be really interesting to discover that fungi, other eukaryotes, or even prokaryotes feel emotions (well, I'm not sure as a vegetarian that I'd actually like that discovery), there isn't any evidence for it yet. There may even be some animals that don't feel emotions, such as sponges or jellyfish which don't have anything even remotely resembling a brain or even ganglia (bundles of nerves, the non-vertebrate version of a brain. Yes, having a separate word for invertebrates is stupid, I agree).

All animals - and certainty all animals with anything even remotely resembling emotions - breathe O2. Of course, we all know who created this O2; Cyanobacteria! Without Cyanobacteria, we couldn't have emotions, since we wouldn't have O2 breathing animals to experience them!

I JUST GOT THE UMICH EMAIL.

sooo … would umich exist with cyanobacteria?

I did too and I GOT IN! <3

UMICH would NOT EXIST without CYANOBACTERIA

As you might imagine, the University of Michigan was founded by Humans from the species Homo Sapiens! As you also might know, if you are familiar with the species, Homo Sapiens need atmospheric O2 to survive. Without Cyanobacteria, this O2 would not exist for them, so they never would have arisen in the first place, and they certainly wouldn't have been able to found U of M!

Btw... do any admitted students to U of M want me to start a Cyanobacteria club when I get there? Genuinely asking....

Would cyanobacteria exist without cyanobacteria?

Cyanobacteria WOULD EXIST without Cyanobacteria

I feel like I've done this one before...

Cyanobacteria would exist without Cyanobacteria... because... obviously? That's like saying "would humans exist without humans". Yes. Obviously the first human (or the first Cyanobacterium) had to come from somewhere, and that somewhere couldn't possibly have been another human (or Cyanobacterium) or else that wouldn't be the first.

Well, you're probably interested in knowing where Cyanobacteria actually came from then, aren't you?

Cyanobacteria probably showed up on Earth about 3700 million years ago, as this is when we first find evidence of Banded Iron Formations (layers of iron oxide which could not exist before Cyanobacteria, as the O2 Cyanobacteria produce is necessary to create them). This would have been towards the end of (or shortly after, depending on how it's defined) the Eoarchean eon, which was pretty much the first time in Earth's history where it was possible for life to come into existence. Safe to say, Cyanobacteria are extremely ancient.

Of course, since Cyanobacteria came into existence so long ago, it would be practically a miracle to find any fossils of their evolution from so long ago - especially since the Late Heavy Bombardment was still happening during the Eoarchean, meaning the Earth was constantly being pelted by meteors, which isn't the best for preserving anything. This means that instead of looking at fossils to find out anything about the origins of Cyanobacteria, we have to look at DNA.

However, on the timescales we're talking about, that's pretty elusive too. Some estimates for the LUCA (last universal common ancestor. The most recent ancestor of *all life* that currently lives on Earth) actually have it existing LESS than 3700 years ago (which doesn't make sense, as Cyanobacteria can't exist before the common ancestor of all current life, including Cyanobacteria. That's the same issue I posed in the first paragraph. It just goes to show how absolutely ancient and mysterious the origins of Cyanobacteria actually are). This means that Cyanobacteria are probably one of the oldest types of bacteria and may have even diverged from the common ancestor of all living things not long after it existed.

Well, the origins of Cyanobacteria might be interesting, but we don't really have much information on them. Regardless though, we do know logically that Cyanobacteria did come into existence without the help of Cyanobacteria, as weird as that may sound!

Thrombolites and/or Stromatolites?

THROMBOLITES and STROMATOLITES would NOT EXIST without Cyanobacteria

Thrombolites and Stromatolites are both types of geological structures (piles of rock) that are composed of biofilms of different types of microorganisms (a ton of microorganisms hanging out together until they pile up and cover a surface. You might be familiar with these if you've ever forgotten to replace your water filter), but most often Cyanobacteria!

When a bunch of Cyanobacteria get together, they form these piles. If the piles have laminae (ridges that kind of look like tree rings), they are considered Stromatolites (as pictured above). Otherwise, they are Thrombolites (below).

Stromatolites and Thrombolites still exist in the modern day, but they're by no means recent! In fact, the oldest fossilized organism we have ever found were a Stromatolite dating all the way back to 3.5 billion years ago (this is so long ago that it was before Cyanobacteria terraformed our entire planet to have an O2 rich atmosphere)!

Also, for those interested, the 'microbial mats' which can go onto form Stromatolites and Thrombolites are the very same microbial mats which were the basis of basically every macroscopic ecosystem during the Precambrian Ediacaran period! The more you learn about Cyanobacteria, the more there is to appreciate!

Not-So-Cyanobacterial Request

Hi guys, weird request, but can you guys PLEASE pray for me to get into the University of Michigan this Friday at 3:00 EST (of course, since UMich wouldn't exist without Cyanobacteria, the topic is still relevant to this blog)?

If I get in, I'll be able to research Cyanobacteria in real life, not just on Tumblr! Please do Cyanobacteria's biggest fan the world's biggest favor!! <3

If I get in, I'll answer lots of asks on Saturday evening or Sunday. <3

[does-this-require-cyanobacteria]

I couldn’t exist without Cyanobacteria. not because of oxygen but because I would be too sad…

I would also NOT EXIST without CYANOBACTERIA

Because I wouldn't be able to breathe (contrary to popular belief, it is an O2 breather that runs this account, not a superintelligent Cyanobacterium), but also because my life's passion would cease to exist.

[does-this-require-cyanobacteria]

No. Way. I'm famous enough to make it onto one of these brackets!?

I better win, considering none of these other blogs would exist without Cyanobacteria!

The reactions to my previous post made me realize I should probably post all the competitors that are a part of this competition, in alphabetical order. This will be split into several reblogs to bypass the mention limit. I'll leave this to simmer a bit before I actually get around to seeding.

If you're on this list and don't want to be, please let me know!
