theres also a definition of a what a tree in the sense , its develops wood, many things are tree like, but not trees: such as palms(just overgrown herbs), dracaena( aka cabbage tree, they have something dracenoid thickining.) extinct plants like giant lycophytes and ferns
Same for roots, btw, just earlier.
There are fern trees, conifer trees, and flowering trees. Where are my moss trees?
Except clubmoss isn’t moss iirc? They’re vascular and more of a fern than moss.
Shhhh hahaha
I wasn’t ready for how weird this comment section turned out to be…
Based on your username, you should be used to weird shit.
Doesn’t mean I can’t still be awe’d though!
Concentrated sun energy sinks
So if you look at a tiny blade of grass and a gigantic tree its like looking at a Chihuahua and a brachiosaurus. And there are smaller things and bigger things in the aminal kingdum!
It’s also mindblowing that chihuahua and tibetan mastiff belong to the same species even tho they look entirely different.
also that humans did that is wild
I always liked the idea of being a tree like life form.
Imagine looking down at a bunch of cute little things crawling all over you for hundreds of years and then one day one of them shows up with an axe
Or maybe the microorganisms and food sources that life forms are exposed to have more of an effect on how the macroorganisms evolve than is currently talked about, which would explain why so many things in similar environments evolve similar traits.
Well, I’m just a product of my environment.
By the logic we are not humans…
no, we didn’t have mice and also ants evolve into humans… there’s one distinct line of ancestors…
it’s called convergent evolution. check out wikipedialogic
Are at least all woody plants related?
As far as they are all vascular plants, but that’s like, basically everything that isn’t moss iirc.
The evolution of wood is common because it’s simple for cellulose to get denser in response to a need to grow taller to outcompete your neighbors.
So trees are the “evolve to crabs” meme and wood is like a crab shell. Or, I guess just exoskeleton, because things that aren’t crabs also have hard shells.
Kinda! But the shell isn’t what the carcinization memes are referring to. I’d say the biggest part of carcinization is the loss of crustacean tails. Basically every false crab is in the process of losing their tail in favor of a rounder body plan
I was under the impression that structural lignin was what really made trees a viable style of growth, and that seems like an odd chemical for a bunch of unrelated plants to all evolve. Is there something I’m missing? Is lignin actually present in all vascular plants?
I wasn’t being specific enough. Cell walls in plants are composed of cellulose, hemicellulose, and lignin. Lignin IS one of the structural polymers that plants produce, and yea, every single vascular plant has and uses lignin to provide structure. Iirc its a polymer produced by every plant, including mosses and other nonvascular plants, it’s just not used to the same extent.
AH, I see. So, it already existed, but until trees evolved, it wasn’t used to such an extreme extent.
Yea, the evolution of vascularity in plants let them get off the ground in the first place (meaning being taller than a few inches). Vascularity is the first big jump plants made after leaving the water. From there, being taller means outcompeting your neighbors and spreading your babies further. When you have that double whammy of more food + more babies, you get a selective pressure for taller that never really goes away. This is why multiple families have species that have arborized and have continuously done so over their evolutionary history. If the niche is empty, something will jump into it, often sooner rather than later (on a deep time scale) which is basically the whole idea of convergent evolution as a whole.
Had to look it up because I didnt beleive
sure enough its correct
Scishow had an episode about it a week ago. It’s a strategy, not a species.
Something poetic and quaint about a link to a Wikipedia article titled “Tree”
reddit has broken me. I was expecting it to point to weed.
Here you go.
Reddit has broken me. I was expecting a rickroll
sooo glad I wasn’t alone.
anyhow, here’s a fun song.
I was expecting an undirected acyclic graph.
Yo momma so fat she sat on a binary tree and squashed it into a linked list in O(1) time.
is a binary tree equivalent to a 2D KD-tree ?
That happens to me constantly
Also cool that for a period of like 60 million years, nothing decomposed dead trees. As they would die or fall over, they’d just stay there, piling up. This is where most oil came from. The massive amounts of trees stacking up before bacteria and fungus evolved to decomposed them. Imagine 60 million years worth of trees just lying around.
*Thought I’d add an edit, since this post got quite a few eyes on it: It was mostly coal that all those trees turned into. Not oil.
Mushrooms are the great undertaker, the great decomposer. The Langoliers. They are just waiting to eat you, and they’re happy to share their fruits in the meantime. They’re fattening you up. They can wait.
That Langoliers reference spotted in the wild!
Now we do the dance of joy!
I remember a flimsy tv film with even flimsier CGI spherical creatures eating the planet
I was struggling to explain the plot of this one to my gf just the other day. Had to pull out screenshots of the TV movie to make it make sense.
I thought that was coal
I imagine dead trees were flammable, even back then. And oxygen levels were 15% higher. Can you imagine the forest fires?
Fire wasn’t invented back then
And after it was invented, it was only in black and white until the 1950s

Didn’t those trees become coal, not oil?
Yes. I made mention of this in a reply to someone else as well. I’m not sure if my teacher (like 30 years ago) told us wrong or if I simply remembered it wrong.
I think near water they became oil and far from water they became coal
No, most coal comes from plants in swamps, because the water helped preserve the organic matter.
Plants in swamps die -> organic matter on the bottom of the swamp -> peat -> brown coal -> black coal.
Oil apparently comes mostly from plankton.
On the different origins: https://www.carboeurope.org/how-are-fossil-fuels-formed-the-science-behind-oil-coal-and-natural-gas/
Cool
Oil was effectively plankton and other sea stuff.
Coal was forests.
Brother I finally found you.
We come from the same place you and me. Remember that barn?
I love this fact, and am curious where you learned it?
I learned it nearly 30 years ago in school. I just did a search and found a link about it, though.
Also, seems that either I remembered wrongly, or my teacher made a mistake, but it seems it was most of the worlds coal; not oil, that came from all the piles of trees from that period.
Correct. In theory, we could make more oil in the lab. We cannot make more coal, because the wood will get broken down by bacteria far before it turns to peat, lignite, sub-bituminous, or bituminous coal, and much less anthracite.
I’m a billion years, crabs will start turning into trees and trees into crabs. merging into the ubercreature
I imagine it’ll look like paras
Paras is a fungus. Totally different thing.
Ah you’re right. Torterra then
Torterra is a tortoise. Totally different thing.
Maybe Pantera?
Pantera is large cats
I’m a billion years
Damn. You look good for your age.
I’d argue, but I agree. I don’t need to know how they look, if they’re a billion years and capable of communicating, whatever state they’re in looks good. Even if its a fungus posessed rot monster.
Like a tree, for example.
I wish, I’m only a crab, trying to become a tree
“ubercreature” excuse me, lichen would like a word with you
lichen is the shit
appreciate when a symbiote becomes it’s own thing.
the tree of life isn’t meant to merge branches,
Eukaryotes, corals, lychens, probably the same with chlorophyll.
you may not like it but Ms Crabtree is what peak performance looks like
