Had to look it up because I didnt beleive
sure enough its correct
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.
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
Scishow had an episode about it a week ago. It’s a strategy, not a species.
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.
Didn’t those trees become coal, not oil?
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?
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.
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 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
deleted by creator
I thought that was coal
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.
I’m a billion years, crabs will start turning into trees and trees into crabs. merging into the ubercreature
I’m a billion years
Damn. You look good for your age.
“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.
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.
you may not like it but Ms Crabtree is what peak performance looks like
Nature likes things that turn hard- Wait what?
Weren’t there like, several millions of years where trees evolved but nothing had come yet to break down wood, so like, generations of dead forest just fell on top of each other until some fungus was like “that looks yummy”?
The molecule is called lignin. And yes, there was a good 60 million years before that particular problem was cracked.
Next is plastics
First, we bio-engineer bacteria and fungi to prefer plastic as food.
Second, these bacteria become a serious endopathogen in the human body while scavenging our precious bodily microplastics.
Third, we engineer a bacteriophage to attack the bacteria in our brains.
Fourth…
The whole human comedy just keeps going and going
The beautiful part is that when wintertime rolls around the gorillas simply freeze to death
Exactly the reference I thought of reading this
I know an old woman who swallowed a fly…
Yes, that’s when coal comes from. There were giant global fire storms, because of all the dead trees and also because there was more oxygen. The oxygen also caused insects to become gigantic. They don’t have lungs, just random holes in their body so the airs oxygen content limits their size.
Yes, that is how we got coal.
we’re living through a similar period but with plastics :)
It’s the circle of life. Plastics are a petrochemical, and those trees created our coal.
Now plastics weren’t technically evolved (unless you count human evolution)…but at least we got CRISPR to maybe speed things along with “evolving” a plastics predator.
i dont really know why human activity should be special. it’s evolved creatures doing weird shit, producing (temporarily?) undigestible stuff. there’s no rule saying you cant have the production outside your body, it’s just customary to use organs.
u might be onto something, this thread sent me down the rabbit hole and penises have evolved independently at least 6 times
here’s a cool blog post that expands on this There’s no such thing as a tree (phylogenetically)
i didn’t even put it in a bookmark folder, it’s just loose on my bookmark bar because it’s such an interesting post that i reread from time to time
That was a very fun and interesting reading! Thanks for sharing
Maybe…but I doubt many of these phylogenies use DNA, and if so, likely only a single or few genes. Nowhere near enough resolution to accurately determine genetic relatedness. Woody plants may actually be more related than we think.
These sorts of phylogenies tend to use morphological characteristics which is an unreliable measure of genetic relatedness.
I will stand corrected if wrong though
So that’s why every stargate planet looks like Canada
Sadly Lemmy isn’t big enough to support niche communities, but I really enjoyed r/unexpectedstargate back in the day.
Isn’t big enough yet ❤️
🤣🤣🤣
That and every Stargate planet is Vancouver
My sister in law recently quipped that “Trees are a social construct” and at first I thought she was just being glib but now I can’t get that statement out of my head.
I listen to a podcast called Completely Arbortrary. They talk about a different tree species each episode. They say trees are a strategy, not a strict definition.
Thanks! Just subscribed. See they have a couple Metasequoia episodes -a favorite of mine .
I think palm trees are a kind of grass
I didn’t know that and I agree
So is corn
And banana
And bamboo
I’m firmly in this camp.
So crabapple trees…?
evolution intensifies
Its called convergent evolution and you also have some shit you wouldnt believe that makes all apes similar to us.
Apes are so similar to us because we came from a common ancestor. I’d love to hear if there are traits we evolved independently after we split though.
Well humans are a type of great ape, sooooll
I’m more of a middling ape myself honestly
Look we cannot compare outselves to the gorilla gorilla, they are the greatest ape, but that does not mean you are not also great
Hit me. I love evolutionary fun facts.
smackkk
Unsurpassable power: https://en.wikipedia.org/wiki/Crabtree
Now we just need crabs to evolve a treecrab and we can have the two battle for the ultimate life form
The absolute peak of evolution. Everyone, go home.
Good moaning!
Not to be confused with Dryococelus aka the “tree lobster”
Also, no such thing as fish.
Google it.
Impossible. If there were no such thing as fish, how could bees be fish?
I don’t have the tools to know how to respond to this comment. You win.
Edit: Holy shit. I just did a quick google. Boydster is not shitting us. Just google “bees are fish.” Oddly enough, this actually furthers the thesis of fish not existing.
To add on for anyone who is lazy like me, the thing where Google summarizes says California has classified bees as fish under an environmental protection act. According to the first result (Reddit) it’s because fish is a catch all term in that law. Instead of listing all the animals they just use fish. Because fish,bees, and the other animals are all invertebrates.
Now whoever reads this has three Lemmy comments, a reddit thread reference, and an ai overview reference as some solid sources
Fish are vertebrates they have a backbone
Some fish are, yeah
Sorry bro, all fish are vertebrates
While I understand it is an arbitrary classification system designed by humans, one of the defining factors of fish is that they are vertebrates.
What about starfishes? Checkmate.
Source?
Because all the sources I’ve come across say that “fish” is not a monophylatic classification and is essentially arbitrary.
What a nicely packaged little subthread to come across while decompressing after a super busy day, lol!
Fish are vertebrates they have a backbone
Beavers are also fish.
This is like the whole, “triceratops didn’t exist, it’s just a young Torosaurus” thing all over again. My world can’t handle this!
Same for roots, btw, just earlier.
And it’s not even one creature or even type of creature. Look up rhizobium.
Tbf, as we learn more about our gut microbiomes, it turns out that humans are that way as well. Maybe that’s why we have the thoughts in our heads vs. the feelings in our guts… (no that’s actually not it at all, except… isn’t it though?).
I figure the feeling of being in your head is simply due to your eyeballs being located there. Now I want to put a 3d camera on my hips, and steam it to VR goggles.
The hips do not lie. Ipso facto, you would be seeing ultimate truth.
It turns out that the meaning of life is at crotch level.
Something, something, biology.
So now I actually think this idea is on to something brilliant. I have been diving into neuroscience lately and this sounds like an amazing experimental method.
It’s like non-surgically transplanting your eyes into your hips. Why do that? To further refine brain-body mapping.
We turn our head instinctively to aid vision. Once our brain realizes that visual input improves only when we move our hips, body awareness will shift significantly.
@DoubleSpace@lemm.ee the best ideas start as jokes
If a future VR is strong enough to embody us in another body — an animal, a conjured crazy creature, whatever — would we eventually “learn” it? Move around in it? Be it? I feel like the answer is yes.
The body is the mind. Change your body, change your mind.
Just saying, polymorph spells are problematic.
I agree with this. But surely there has to be a limit. If we create an extremely complex body where its movement requires solving rhythmic problems based on changing prime numbers, or something like that, would we be able to do it? If we hook up the VR to a squirrel to control a human body, would it be able to do it?
Microphones and headphones too.
People have experimented with that sort of thing. Here’s a DIY for going into 3rd person mode using a camera on a stick and some electronics in a backpack. Bit of googling also finds me body swap experiments, but nothing on a crotch perspective.
Awesome resource, thank you for posting it.
Here’s one reason why a hip level perspective would be so helpful as a neuroscience tool. It is an ethical and reversible experimental intervention that could add real experimental power to functional brain-body mapping.
Combine the perspective shift induced by the virtual rearrangement of sensory input with fNIRS for cortical imaging, perhaps before, during and after the hip-view experience. A company focused on near infrared cortical imaging products
I am certain a proper neuroscientist could come up with even better and more detailed questions to ask using the method.
Something like this could even be used as a therapy tool for trauma, perhaps, once the impact of the perspective shifts were understood well. A common trauma response is dissociation and common therapy methods include ways to help people reconnect with their whole bodies again.
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
