It’s a recurrent theme in the history of the world you know, thousands, hundreds of thousands, tens of millions of species killed, never to be seen again.
Why does the cow shark description say it’s unique in having six and sometimes seven gill slits compared to all other sharks having five. Then the frilled shark says it has six gill slits.
They’re both part of the Hexanchiformes order, which are seven gill sharks. So the cow shark article is wrong, there are two surviving families with more than five gills.
Thank you, I typically default to assuming I don’t understand or I’m confused when reading up things outside of my wheelhouse. I enjoyed reading up on the sharks you shared! I was trying to decide which one I would want to be if I could decide while laying in bed this morning. Felt silly but fuck it, I’m old, it’s nice to dream.
Others have been fairly random. GRBs sterilizing half the planet, asteroid impacts, simple microbiological species fighting for resources whilst unknowingly making their environments unlivable, etc., etc.
In this case, the writing has been on the wall for decades, completely preventable, but here we are barrelling into it head first none-the-less. Dumber indeed.
The problem is that not everyone shares the same values, and so there are people who are willing to let some species go in exchange for a more comfortable lifestyle (with “more comfortable” in some cases meaning “not starving to death”). Values aren’t objective.

No species ever lasts that long.
Sharks enter the thread.
Awkward silence ensues
Shark species go extinct all the time. New shark species arise.
Except for these species, classified as living fossils:

I hope you picked Goblin shark. You get to be “ugly” and don’t give a fuck and outlive your enemies lives anyways.
There have been many extinction events, and we won’t be the first “nature based extinction event” the planet has seen either.
Just one of the dumber ones.

Hardly. We conserve when we want to.
