You should study some extreme cells or some extreme plant life. So don't forget mushrooms where the first on land and made the rock into food. Hell mushrooms use to get 10 and more feet tall.
Many people in comments below are complaining about the slow delivery. Pay them no mind. They're probably new here. They don't know you're just following Hank's lead. Don't worry, they'll catch on - Or they won't, in which case, let them "vote with their feet". The remaining 600K+ of us won't miss them. The fact that you don't hear from those of us who *DO* like the pace, is that we've been subscribers for years, and have come to enjoy it, and *expect* it. Besides, it gives us more time to enjoy the wonderful images. (Thank you, James!)
As a biologist who did his Master's during the pandemic, I thank you whole-heartedly for these videos. They help stay in contact to my passion (biodiversity) while also swimming on the job market. Thank you!
@@unhappyman100 "So can you tell me what a woman is?" Legally there is no definition of "woman" that does not have some biological exceptions. Someone with CAES is XY but develops as a woman. Someone with Klinefeltters Syndrome has a penis but develops as a woman. The default condition in mammals is female (that is why men have nipples). So while it might seem straightforward, no, I cannot tell you with 100% certainty what a woman is.
Would it not make more sense that the algae developed slowly in tidal areas? Starting by slowly developing resistance to UV and periodically drying out, would mean it could survive in tidal pools etc. That would then lead to being able to survive on surfaces only flooded during high tide, to surfaces only covered by spray, to eventually on land. This way it would be one species’ gradual change to adapt to a niche where others could not survive, rather than some special circumstance.
Only saline edge environments are much harsher than fresh water. And to move onto land you have to use freshwater from the ground and rain/fog. But translate your idea over to a freshwater pond on a foggy mountain side that has an inconsistent water level you might have a winner.
Mosses and Liverworts start their lives looking like algae. In Liverworts this is followed by strap like or lobed phase which resemble a prostrate seaweed. (Though leafy liverworts resemble mosses.) Mosses and liverworts are called Bryophytes or Seaweed Plants. The embryo is formed on the upper surface leading to a stalk and spore bearing structure. I am guessing this would have been enough to distribute the spores better than spores forming directly on the plant. This is part of the Alternation of Generations which seems to be largely ignored today.
Plants, as well as algae and fungi have a symbiotic relationship. Perhaps the fungi began to colonize the land first and the algae subsequently followed the fungi. Interesting and thought provoking subject none the less.
Pretty sure fungi were the first organisms to colonize land far away from rivers and lakes. Fungi are basically responsible for the creation of dirt. Fungi today are incredibly important symbionts of about 90% of land plants. I love Fungi :)
@@casualsatanist5808 yeah that’s what I heard too, that Fungi was basically the catalyst to land plant evolution. That they’d eat minerals from rocks and pond/river algae had the water. The fungi gets nutrients from the algae, and the algae gets complex minerals it would have never gotten before, allowing it to further adapt to the environment
There were really big lichens before the big plants. There are still some plant-looking lichens in polar regions. That possibly means the cooler planets have very plant looking lichens in place of plants.
@@nathanlevesque7812 hornworts (Anthocerotophyta) belong to the "bryophyte" grouping too. The gametophytes are thalloid plants and basically look like a flat translucent green mass. They're unusual among bryophytes because they have special "slime cavities" for symbiotic bacteria to live in and have one giant chloroplast per cell. The sporophyte is strange because it looks like an upright thread or a "horn", is long lived and can photosynthesize. I've seen information that in fact hornworts are more closely related to tracheophytes than other bryophytes, but I'm not sure if it is true. Regardless they're very interesting plants. They are found everywhere around the world except Antarctica but often to unnoticed because the smallest members are about 1 cm in diameter
Glad to see you taking feedback toward your narration seriously Deboki! Your tone is much more relaxing, and I like the slower pace. I'd say just a tad faster would be great. I feel the best style would be like you're reading a bedtime story to a child - you want to go fast and energetic enough to keep interest, but slow and calm enough to allow them to stay relaxed. Once you find that perfect balance, I'm confident your voice over quality will go up to the next level. Keep at it! And thank you for the excellent writing.
Perhaps early land plants survived dessication through cryptobiosis and became increasingly adept at maintaining normal functions as water levels decreased. Then they could progress to a state where dessication is almost a nonissue, and cryptobiosis is supplanted by a milder, nutrient-storage focused set of adaptations.
maybe the early streptophytes lived in tidal pools, or shallow waters, where they might be exposed to air or water at any moment, and fundamentally had an ability to handle both, before colonising land?
It's amazing how I went from not caring much about plants, to being fascinated by them. It all began accidentally when I found a fossil (pecopteris) that turned out to be ~300 million years old. Now, I have hundreds of them. They all fascinate me.
i had a professor who's a paleobotanist. he told me that it's likely plants developed from those algae mats that form terrestrially in high humidity and rainfall zones and developed into superorganisms that looked like thalloid liverworts, which would make sense since liverworts are the most primitive true plants that still survive today that we know of. it's also believed that bryophytes don't have true stomata since stomata developed in the transition phase between advanced moss-like bryophytes and pteridophytes, such as from the now extinct cooksonia plants.
Mosses have stomata, but only on their sporophyte stage. Hornworts also have stomata on their sporophytes. The only embryophytes that lack stomata are liverworts and those aquatic plants that have lost them through adapting to an aquatic environment.
My theory is, that the transition from water to land in plants happened in a pond which was flooded and dried out on a daily basis, so the plants there had to adapt just a temporary survival outside of water. After these properties were well established, the adaption to longer dry periods up to relying just on rain and groundwater instead of floods were probably the next thing.
Also, lots of folks are claiming the narration is a tad slow so x1.25 speed makes it sound better paced, and I agree. I like the voice and tone of her, she just needs a little faster pacing. Great video as always, tho.
It's the same media company owned by the team that does this, Crash Course, Sci Show, PBS Eons etc. Hank Green does the narration on most of the shows (I don't know their relationship to PBS Aeons but they do that also), so he's also a co owner, the idea was to make a science video media company that's not bullshit
Her speech sounds so much more natural at x1.25 speed, I was feeling frustrated with how slow "she was speaking," but I imagine you changed it on purpose to make it more accessible or something? Your channel of course, but I prefer the original speed for what it's worth unless I assumed wrong. That's not worth criticizing though, just wanted to mention, thank you!
Interesting. The slow speech is part of the vibe this channel has as an original stated goal. Usually I get annoyed by "x1.25 is better" type comments, but after listening at x1.25 speed...I genuinely can't tell which was the original speed of audio. Chakravarti has a very nice-sounding voice and I don't mind the slow narration, but it is weird that you can't tell if that was the original speed or not.
People, you can change the audio track language from English to Spanish, but the Spanish is an odd voice. It's a development with great potential, just not perfected yet
One possible reason liverworts lost or never evolved stomata is simply that they cannot afford any transpiration of water out to the environment. This is probably a consequence of their rhizoids being small and not suited to large scale absorption of water from the environment. Therefore stomata are probably an evolution of taller tracheophytes with larger root systems living in dryer environments.
Many mosses and liverworts do have conducting tissues. The tissues are probably controlled by the same genes, and in mosses they are structurally the same as those of vascular plants, so they are likely homologous. The difference is that tracheophyte vascular tissue contains lignin. Some of the earliest fossil "tracheophytes" have had to be reclassified because it turned out their vascular tissue did not contain lignin. The separation of the basis of vascular tissue is an old distinction made when most botanists knew little about mosses and liverworts, and did not bother to study them. A better distinction is that bryophytes produce an unbranching sporophyte with a single spore capsule, and vascular plant sporophytes branch and produce many spore capsules. There are also a LOT of evolutionary adaptations in bryophytes for living on land that vascular plants lack, including proteins that protect the DNA during drying. The bryologists have lots of information about the transition to land that have not made it into the textbooks. Botanists who only know vascular plants are mostly unaware of this information, and therefore are puzzled about the transition to land. Ask a bryologist, and you'll have a lot more information.
Fish would have climbed onto land way before plants arrived. They are cold blooded, so sunbasking like crocodiles is a good way to make themselves more energy efficient and there was no great risk of being eaten with tetrapods not existing.
@@UniDocs_Mahapushpa_Cyavana - But they didn't. AFAIK the order is plants, insects, vertebrates (each needs the former, plants need nothing but sun, air, water and some minerals).
"Decided to do without it" it's often risky to talk about evolution in that way, leaving room for design and choice, but in the end questioning inevitability and how hindsight is convenient is a great way to describe evolution 😁 Great vid!
@@gregoryfenn1462 yes, to the informed, it's a metaphor. To the uninformed, they might take it as evidence that evolution has direction/intent. Remembering to consider the potential perspectives of others can nip misunderstanding in the bud :)
Would you perhaps be willing to to a video on the interaction of fungi and algae or plants? Yes, like lichen. But if there are any other examples as well. Perhaps I'm misremembering but I heard there was a theory that some characteristics of modern plants have possibly been acquired through horizontal gene transfer from fungi in the past
Aaand thank you for filling me in on the fact that what I learned in my botany class and what I've been teaching up until now is wrong (at least with regards to the origin of stomata) Ahh the beauty of liverwort air pores being a transitional structure was just not meant to be. It's pretty unusual for a presumed paraphyletic group to then be resolved as monophyletic though. Fascinating. I'll be distracted for the next few hours reading papers on the subject ... starting with: Phylogenomic Evidence for the Monophyly of Bryophytes and the Reductive Evolution of Stomata

For the record I do not know of a single marine algal lineage that made its way onto land. All land plants are descended from freshwater green algae, not marine algae.
That massive shared history of land plants is very obvious when you watch them go from seed to plant. They all have the same first two leaves. It's only later leaves that are unique to the plant species.
Well, not quite! There’s a large swathe of plants (grasses, orchids, corn) called monocots, which only have one leaf when first sprouting. You’re taking about dicots, which have two after first germinating. In truth, there are countless differences between even germination requirements between members of either group. There’s a lot more to it than meets the eye!
Surprisingly early, plants made associations with fungi. Perhaps this was the super-power that allowed the plants to live on land. Mycorrhizal fungi might make a good episode, with it's penetrating under the cell wall of roots to trade minerals for sugars. Exploring new soil to boldly go where no plant has gone before!
Lionel Messi was first formed when a magnet was wrapped around a wire that was wrapped around a football, in his dad's magnet factory in Rosario, Santa Fe. His parents repeated the experiments, resulting in Rodrigo and Matías, and shared this secret with their siblings, resulting in Maximiliano and Emanuel Biancucchi, though the Lionel experiment was found to be the best.

Good voice, Deboki. Something is different about this voice. Or maybe this was all inevitable, or some scenario similar to what looks like happened in our past was actually planned. It all happened and did so in good order with minimum waste and here and there minimum time.

@@LuisAldamiz Ah, the shortcomings of intonation- and body-language-free communication! I was too quick to assume you were being a pedant (and a wrong one at that) - o how the turntables!
@@mostlyokay - Fair enough, I guess. No offense meant, no offense taken.
I liked the male voice over better, but the content is still top notch! Looks so sharp and vivid.
A bit too slow on narration, miss the old narrator guy - still a cool video otherwise don't forget the hornworms and bryophytes!
New word of the day: clade.

Hi, Is your microscope capable enough to make a video of the bacteria colonies in the belly of vulture bees?
LAND PLANTS
Please help me to further the science of this topic. I'm a plant and soil scientist. I would love to see the sea more.
It’s like listening in half speed.
In bryophytes you missed Hornworts....😊
Good voice, Deboki. Something is different about this voice. Or maybe this was all inevitable, or some scenario similar to what looks like happened in our past was actually planned. It all happened and did so in good order with minimum waste and here and there minimum time.
For some reason this episode is in Spanish for me and I have no idea why and nobody else is acknowledging it and I feel like I’m going insane
Never underestimate the evolutionary power of being first :-)
The better host is on today. I wish she was the only host.
Love One Another God Bless Everyone:)
Where's hank?
That "plant" climbing up the corner of my room is liable to be mildew. Just saying.
What happened to the dude?
Anyone else bothered by the bird in the wren logo not having an upright tail?
I like the narration on this one.
For a moment i thought i was watching PBS Eons...
