So The Megalodon Is Most Definitely Extinct? How Do Scientists Know?

so the megalodon is most definitely extinct? how do scientists know?

well, the thing about large predators is that they leave an impact on an ecosystem big enough that you can tell they’re there, even if you never observe one directly. in this case, we know they’re definitely extinct because of the behavior of whales! whales used to max out at about 50 ft long and were fast and agile, entirely because of predation by megalodon!

but about 2 million years ago, our whales began to rapidly increase in size until we ended up with real monsters like the blue whale. this pretty directly lines up with the extinction of megalodon, and the removal of the pressure they were putting on large whale populations.

basically, large whales can get away with being gigantic, slow tanks in the oceans today because there simply isn’t a predator big enough to take them on anymore. if megalodon still existed, we would be seeing its impact on whale populations! whales would be smaller, and a hell of a lot more skittish than they are.

everything in a given ecosystem is connected, and you can often get important information about the unknown parts by observing the behavior of other parts of the ecosystem.

Sometimes I think about my FNAF art from 2015, and how my mum literally printed and taped it to the house's front door. They were so bad, but I was stupidly fond of wishing my old awful fnaf oc goodbye at the door every time I left

"Oh no, someone's attracted to the aesthetics of my -punk movement but doesn't know the praxis and history behind it like I do--"

OK. Tell them. Make it a teaching moment. Everyone who's in your movement learned the background from somewhere at some point, maybe this is that point for that person. Give them a jumping off point that they can dive into later.

"Oh but I shouldn't be responsible for teaching baby -punks about the history and the how-tos and--"

OK. Then don't tell them. You don't have to be responsible for teaching people with a budding interest in your group the ins and outs and how-tos. That's fair and valid! It can be a lot of work. Someone else will handle it

"But I'm annoyed that they would try to claim to be part of/be interested in my community without knowing all the details that I know after being in it for months/years/decades, they're dumb, they're posers, they're--"

OK. Then don't engage with them, if it's that bad. Maybe someone else will come around and tell them the history, maybe they'll pick it up on their own, maybe they'll just enjoy the fashion elements for awhile.

"But they shouldn't claim to be part of the -punk community if they don't know the--"

I feel like we have a few options here. People can either talk to them, share the history, share the values, share the praxis. Or they can just chase off anyone who even thinks about dipping a toe in their community, and then wonder why it's dying off later down the line.

I dunno, maybe I'm too naive and patient or whatever. But if people are entering your -punk spaces without knowing The Rundown of what you feel they need to know, maybe being nice about it and informing people instead of immediately assuming stupidity and malicious intent could help you make a new friend. Even the loudest voices in a space had to learn from somewhere, and not everyone has the luxury of being in the space as the History was Happening--whether it's an age thing or a not being aware of the space thing. Or maybe I just don't see what the big deal is behind people hating people who like the aesthetic of something and don't know the behind the scenes history about it yet.

Because I believe in the word 'yet.' No one comes into this world knowing everything about everything, and we're all constantly learning new things. I'm not gonna degrade someone and call them a poser for not knowing what I know. Because if it were me, interested in a scene but getting chased out and called a poser? I wouldn't hit the books and study up, I'd go 'that fuckin sucks, those people sucked' and then avoid anyone and anything having to do with it.

So chase people off and call them posers if you want. But if your community starts dwindling, don't be fucking shocked.

"Rotating it in my mind" started on Tumblr as a COGIATI joke and took off hard with everyteenager4free using it, which gave cis people this beautiful phrase that they don't know how to use

hate how so much of adult friendship relies on updates, experiencing your life through pictures and tidbits. we had it good with childhood friends, could spend years and years basking in the same circumstance. now i just float through clouds of strangers, hungry for something solid and warm. yes i carry your heart within mine, yes i see the world through your eyes. but in that very moment i still feel alone, still know it's poor substitute for same room, twin smiles.
