Adam’s transition into being a dude who likes talking about his nerdy hobbies is one of the best things ever

Adam tries to speedrun evolution in his backyard

Adam did a great thing by branding his channel with his own name instead of some kind of a food-based channel name. This way he can do whatever "Adam Ragusea" does and not what a "food" channel is expected to do. (edit) SEAfood Ragu recipe when??

Oh no he's becoming God

This is a positive comment for the KZfaq algorithm

Nice video! As a biologist, I really enjoy seeing Adam nerdying about these topics. Just one comment though: at 9:05 he says that land plants evolved from cyanobacteria, which is not the case. Plants are eukaryotes, which are veeery distant relatives of prokaryotes like cyanobacteria. Plants' chloroplasts, on the other hand, *are* cyanobacteria (or at least used to be). These organelles originated from endosymbiosis, when a distant unicellular ancestor of plants engulfed a cyanobacterium and, instead of digesting it as it normally would, developed an intricate relationship with it. Over eons, the cyanobacterium became part of the other cell. That is pretty cool ^^

THE CRAB EATING THE FLOWER WITH HIS LITTLE CLAWS IS THE CUTEST THING THAT I'VE EVER SEEN!!!!!! (3:54)

Fun fact about the Great Oxidation Event The title "Rusting of the Earth" isn't metaphorical. Before oxygen became such a prominent component of Earth's atmosphere, there was a lot of pure metallic iron just floating around in the oceans. But when all that photosynthesis kicked in, there was suddenly a whole lot of oxygen around to turn that iron into rust. We know this because in places all around the world, you can find sedimentary rock with alternating layers of iron oxides and iron-poor rock (alternating because, as Adam mentioned in the video, the cyanobacteria would photosynthesize for a while, then die back until oxygen levels dropped and start again).

Adam could make a video on literally anything, and I would absolutely watch it

Adam is certainly the only KZfaq foodie who can give a competent video about the origins of life, complete with his own terrarium.

Your greenhouse is so gorgeous, im incredibly jealous. It seems like an incredibly peaceful place.

Im addicted. Its crazy how im just following along becuase im so invested in his production. Everyrhing he does has so much flavor and zest. Hes a born online personality. Radio did him so many favors.

"the crab tank project" is a phrase my brain immediately interpreted in the coolest way possible

Cyanobacteria don't do photosynthesis "just like plants" but arguably they do it FOR plants! The plastids in the plant cell come from cyanobacteria that integrated within the eukaryotic cell to the point of being an integral part of it. This was the second time endosymbiosis of bacteria within eukaryotes gained them an additional and fundamental organelle

I originally came to this channel to learn how to make some pizza but stayed for the tangents and side content

The evolution of Adam's content has been one of my favourite developments of my modern KZfaq landscape

Adam is like that one weird but slightly deranged cool uncle

Love how wholesome the whole aquarium saga has been

Adam talking about science is the best thing ever. Thanks for the transition.

The most important part of this video is that Adam has a crab, a very tiny very precious very adorable lil crab. I would die for that crab. Update: We must find this crab

Love the loaches wriggling up above the waterline to nip at the terrestrial tasties!

"This is what I get for considering aesthetics" toooooooo real There are home projects that look good, and home projects that work. Never the twain shall meet

Your home is so beautiful. I've always had a vague sense of what a dream house could be for me but looking at all of the green, the trees, and the little pond I'd like to imagine that that is a dream home. All of the green and the water tend to help my mental health and I'd imagine it does so for others. But here I am in desert SoCal

It brings me great joy to be able to experience Adam's "listen to me nerd out about this thing I found cool" era.

I'm loving this "I'm just gonna talk about stuff I find interesting" Adam arc. I always learn something new that will inevitably put me in a Wikipedia rabbithole until 4am in the morning!

I LOVE your recent videos. You've explained evolution very accurately despite having a limited timeframe and an audience that may or may not understand more academic topics. "Life is just stuff that self sustains, and it's still here because well... it sustains itself"

I love that the feel of your interests and channel is akin to @AtomicShrimp 's variety videos!. Thank you for sharing those parts of yourself c:

You may be semi retired but the videos you've been making have been knocking it out of the park regardless!

I absolutely adore this new format for you, Adam. So glad to see you doing things you REALLY want to make. It is obvious in your presentation and content!

I loved the shots of the little loach or catfish beaching himself to get at the delicious goo.

That green house looks amazingly peaceful. I feel relaxed just watching that colorful crab eat that tiny flower

I love the variety of his videos. Great videos that provide joyful and educational content

i love the new version of adams channel even more and i hope it is still serving his personal/mental health goals. this is not the first time one of these has come out about a question that i've been thinking about but haven't read enough about to have more than a basic understanding of

I really appreciate these new videos from prof. Regusea. Also those Vampire crabs are adorable and need names

Ill say it again, seeing this channel transition into my biggest hobby (aquaria) is the best character arc of all time

i had stumbled upon your first tank video just a while ago and got sad that there was no follow up. i'm so glad we get to see it again!

YES WE WANT MORE UPDATES ON THE TANKS Especially about these adorable crabs !!

That's an adorably bright and colorful crab

I think I've slowly fallen in love with this dude

Love your gardening adventures, Mr. Semi-Retired Ragusea.

Love that crab tank, Adam! I'll go check out the build video now.

Crabitat coming along gorgeously

Love this transition into Adam's nerdy little hobbies and construction ideas

That Terrarium / Aquarium is absolutely AMAZING!! SO FREAKING cool!! I could watch it all day!!

As guy that subbed for the cooking videos, I absolutely love seeing the aquaria and garden videos! More of this wouldn’t be a bad thing in the least! I’d actually enjoy seeing more of it!

The time has come for an Adam Ragusea - Brady Brandwood collab.

So glad to see updates on these projects! Would love to see more aquaria and terraria and definitely whatever raised gardens you end up making 👍

Love seeing updates on your projects, thanks for sharing!! The aquariums and tbh the whole greenhouse are so dreamy!

The fish eating the algae on the land was really eye opening for me. Such a cool live demonstration of how land animals evolved

I really liked seeing the follow ups on all your little experiments

you have no idea how excited i got seeing it was you posting a video on this subject. like a giddy little girl.

Love the wider ranging video topics - more talk about plants and sludge please!

Projects looking good, Adam! Thanks for sharing

Hey Adam, great video. I love the tank and the whole greenhouse! It's beautiful! I know other commenters have already pointed it out, but it bears repeating (and with a few other points) that plants aren't descended from cyanobacteria - or any bacteria. At least not in the traditional sense of the word "descent". Plants, like animals and fungi, are Eukaryotes, a type of cell with a membrane-bound nucleus and organelles. Bacteria (as well as their distant cousins, Archaea) as prokaryotes, which lack a nucleus. Prokaryotes are much smaller and simpler than eukaryotes, and they just have their DNA floating around in their cell, rather than being stored in the nucleus like Eukaryotes. Eukaryotes are thought to be descended from Archaea, rather than bacteria. So the single cellular ancestor of plants would have had a nucleus, mitochondria, organelles and all that, and therefore, would have been a single-celled eukaryote. So plants evolved from algae, which are other eukaryotes. Now, as others have already mentioned, there is a connection between plants and cyanobacteria. A eukaryote long before plants was able to incorporate a much smaller, much simpler bacterial cell into their own cellular system through endosymbiosis. This resulted in the development of chloroplasts, an organelle that helps in performing the function of photosynthesis for the cell. Some of those cells with chloroplasts became green algae, and eventually, land plants emerged from green algae that became more and more adapted for life on land. So plants aren't descended from cyanobacteria that developed multicellularity once they reached land, but they do have cyanobacteria inside of them. Plants are descended from green algae that made their way to the land, which are descended from marine green algae, which are descended from the marine-based common ancestor of most of the lineages of photosynthetic eukaryotes who swallowed a little cyanobacteria and didn't digest it but started working with it.

One of my favourite youtubers talking about one of my favourite topics is a true delight!

I love to see a new video of urs pop up so often. I also love u talking about aquariums as I am a hobbiest as well lol

I absolutely LOVE these videos! Adam’s able to explain the most complicated things in such an easy to understand way.

Honestly one of the best youtubers in terms of how human the videos feel

This video was just an excuse for Adam to show us all the cool stuff he's been doing since the last greenhouse vid, and I'm here for it.

dude! your greenhouse, aquaria and terraria are amazing! Love this "What Adam was thinking about at this point" content!

I very much appreciate the evolution of your website. You look much happier. From my experience, keep pushing the envelope.

I enjoyed the main video as it was interesting and informative, especially as we have an explosion of blue-green algae in our main lake here in Northern Ireland... however I just wanted to say that I loved the update on the greenhouse and the other projects too. Petition to keep the regular updates coming as a treat at the end of the usual video.

Thanks for the updates on the plants 😄

My dad watched some of this with me and found the star trek action figures amusing. And i think your pond is absolutely beautiful! It looks perfect

I enjoyed the updates. I really like how things are going with aquarium, very cool

I think this is the best video to show someone to teach them about evolution in the easiest way possible

I'm all for this video. I might honestly not watch your videos as often now but I certainly still enjoy them and that sounds like what we both need, so congratulations and enjoy fading back into non celebrity status

Thank you so much for showing us your aquariums, they are so pretty and I love seeing them! :)

wait a minute this isn't SciShow

Love greenhouse and fardening content! Greetings from Germany.

wow, i can't believe I've just gotten one of the most understandable and well worded lessons on early life on earth from Adam Ragusea... I love it!

Loved the update at the end of the video, great stuff, keep it up.

I love this type of content a lot. I would love to see more. It's right up my alley

Love your mind!! Been here for years, you cover all my favorite bases!

Your greenhouse is so pretty. I love it so so much. I hope someday i can make my own. Keep up the great work.

I remember the first video I saw of Adam, it was how we used stones to boiled water. This is the kind of videos I really enjoy

I love the disco ball. I have a big one, and now I feel like it should go in my greenhouse

I love the waterfall and river aquarium! 😻 Absolutely obsessed!

Thanks, Adam. I appreciate you.

adam im rlly high rn but this video made me so happy. I will always watch the fuck outta these chill greenhouse update videos.

This was awesome, reminded me of some of the old podcast topics. MOAR (but at a healthy work/life balance level)

I love this, thanks for making this video. I never much thought about how it actually might have looked like at the beginning of life on land. We tend to imagine violent boiling tide pools of murky sludge and somehow life comes about. But this paints a much more gentle and tranquil picture, like a zen garden that created itself the gentle trickle of water onto the very earth all earth should grow on. very nice

your aquatic videos are one of my favorite.

Hearing Adam talk about stuff always cheers me up

Okay Adam delving into this stuff that I already have an interest in... YES MOAR

Adam, I tried designing and printing strawberry rafts a few years back. The design focused on those net cups you'd buy for a hydroponic setup, they slotted into a kind of floating cradle of hollow rings and spheres. At first, it worked, but I learned two things. One; FDM printed plastics will deteriorate in the elements and eventually the titanic like system of chambers would fill and sink despite my attempt to apply a waterproof coating. Two; even a pond with too much gunk in it to see to the bottom still isnt rich enough to fully support a strawberry, but it does grow some impressive roots. I think in the future if I try it again, I might honestly just try making the flotation parts out of ping pong balls epoxy'd to wire rings or something and then coat that, just make it very light and hope the ping pong balls hold up in the sun better. I'd also still use the net cups but plant them in one of those seed start soil plugs and see if that helps things. anyway good luck, this is one of those projects I just wanna see someone succeed at lol.

I love videos like this. Great job Arag

I love this turn the channel has come to!!

Food videos are ok because you make it interesting with science stuff but these really are the best videos!

Tip for the strawberry rafts: you can still use wood but I suggest you put some small water bottles(thin glass or plastic is ok) filled with air underneath them and those should help the raft not sink for a very long time. Or you could just use bamboo since they contain a lot of air and are stable for longer.

absolutely gorgeous greenhouse, adam. so cool. i've always wanted to do that

thank you for the terrarium update

That's a really lovely aquarium. It's so nice to see a bit of ecological complexity for the fish to engage with. There is nothing sadder than a couple of fish swimming around in a barren oblong with a plastic castle.

Great video and thank you for the updates on tanks and tomatoes! Also, love the Beverly Crusher figure in there hehe (at least it sure looked like Dr Crusher to me)

I did not know it was only 500m years ago that plant colonisation really began. For some reason I though it was earlier. Great to learn something new while watching a cute little crab have lunch.

I appreciate that Adam is willing to show that his ideas don't always work, it's easy to lie about, but trial and error is content baby

I love how my teeny tiny purple crabby boy is just casually nibbling his way through the video

I'm a simple man. I see Adam Ragusea's new upload, I give a Like before watch

Neocardinia are very bold, especially in flowing water. Their native habitat is small streams, so they love exploring any flowing water where they can fit even partly submerged. They're also not as sensitive to drying out as fish.

It is cool how succulent plants got to survive on this moist enviroment.
