Global Warming Made Sharks Huge; My Anxiety Says I'm Next

Ever asked yourself about the point of existence? No? Just me then. Well, as I debate the fleeting nature of life, I also delve deep into how freaking ancient global warming made sharks not just bigger but absolute units of terror. Trust me, the irony of considering my own existential dread alongside prehistoric shark growth spurts isn't lost on me.

So, from a study that's as hard to digest as my morning antidepressants, scientists in the journal Current Biology dove into the shark-evolution pool, measuring enthusiasts. They analyzed fin sizes and body lengths of a whopping 500 sharks—that’s extinct and living, by the way, not zombie sharks (although how cool would that be?). Their conclusion? Some 122 million years ago, during an oceanic bake-off known as the Cretaceous period, sharks got swole.

Apparently, when the ocean turned into a giant hot tub, some bottom-dwelling, antisocial sharks thought, "Enough of this floor hugging," and moved to the open waters. Moving on up, quite literally. This major shift in address tweaked their body structures: fins out, muscles up. Kinda like me moving out of my parent's basement... except successful.

Now, most sharks you think of (thanks, Jaws and Sharknado) are these ripped, agile, hunters of the deep. But hey, many were always just chilling on the sea floor, kind of like how I linger at the snack table at parties. Except they didn’t need to continuous swim to breathe. Fancy, huh?

But get this—the need to breathe might have been driven by the Cretaceous basement getting stuffy with low oxygen. So really, nature was like, “Breathe or move, your choice.” Quite the motivational speaker, that nature.

Ending on a dark but fitting note—would you rather evolve and grow, or suffocate in the comfort of your old ways? As for me, I'll be pondering that with a dark humor, much like dying alone, which statistically is less likely than being eaten by a shark. But hey, either way, what a way to go, right?
