See how did sharks swim north without the north being there?
Much of Earth's water is older than the Sun so the shark's likely swam from space is my best guess.
I mean the protons and neutrons are never new, all of this stuff is just second hand, cobbled together recycled garbage!
What is a proton? A miserable pile of quarks!
Like they say, we're all just nuclear waste.
I just checked, Polaris is about ten times younger than sharks. The other two stars of its ternary star system are older, but not visible to the naked eye, so early sharks would not have been able to use them for purposes of navigation.
Polaris is 45-67 million years old.
The oldest total-group chondrichthyans, known as acanthodians or "spiny sharks", appeared during the Early Silurian, around 439 million years ago.
It's not even close.
Dinosaurs died off 65 MYA. Dinosaurs were most likely gone before Polaris formed.
They probably died off because they couldn’t use Polaris for navigation!
Polaris goes in and out of North Star status on the 26,000 year precession cycle. So for the duration of humanity (let's say 100,000 years), there have been decent chunks of time where it's not in use.
You gotta rest up man, that's a pretty big job for one star
They trade off. There are other stars that make for good pole star candidates
Can you imagine having to give directions to a bunch of illiterate primates? Ugg. I’d have quite after the first thousand years.
I’m now sad that dinosaurs could never look up and see Polaris.
Most nights even I can barely see Polaris.
Eh, they got to see the thousands of other stars that are now obscured by light/atmospheric pollution.
I came here to question whether that claim is true, saw your post, and thought something like "well, that settles that." Then I scrolled down and saw neatchee's (great username) post and now my whole world is uncertain.
Appalachian mountains are even older
Sharks are older than trees.
They're older than a lot of things. Land plants, Yellowstone, appendages,dinosaurs, doritos.
Appendages? Like, fins?
Like appendix I imagine.
He's thinking of penguins
Sharks are older than trees.
But are younger than the mountains.
Some of it.
Ehhhh they're younger than some mountains though. There are ranges that are over a billion years old, but the Himalayas are "only" some 40-70 million years old, depending on when you start counting (40-50 if you actually start from being mountains, 70 if you start from "ground moves up")
Why did I read this to the tune of colors of the wind…
Sharks are older than the grinning bobcat
Yellowstone
Well....
The geologic processes that led to the formation of the Appalachian Mountains started 1.1 billion years ago.
There's no shark without Mountain Mama
What do you think the first several hundreds of millions of years were like before they had Doritos?
I refuse to believe any animal is older than doritos
No they are wrong. Doritos are eternal.
One of my favorites is "the Appalachian mountains are older than bones"
and bones are I turn older than Saturn's rings, by about 300 million years
...wait
Bones evolved for the first time: "485 Ma First vertebrates with true bones (jawless fishes)" -- https://en.wikipedia.org/wiki/Timeline_of_the_evolutionary_history_of_life (Vertebrates existed without a bony notochord before then.)
But the Appalachians were started much earlier: "The geologic processes that led to the formation of the Appalachian Mountains started 1.1 billion years ago." They were basically finished growing by the time bones existed: "Around 480 million years ago, geologic processes began that led to three distinct orogenic eras that created much of the surface structure seen in today's Appalachians. [d] During this period, mountains once reached elevations similar to those of the Alps and the Rockies" Since then, it's just been wearing down. -- https://en.wikipedia.org/wiki/Appalachian_Mountains
Thanks, I hate it
Now wait until you hear about skinteeth.
holu shit polaris is super young 
This is only sort of true, unfortunately. Polaris is a two-star system: Polaris Aa and Polaris B.
Polaris B is much older than sharks, by several billion years.
Polaris Aa appears to be younger than sharks, at a measley 50 million years old, compared to sharks' 420 million years
HOWEVER it is unclear whether Polaris Aa is actually that young. Scientists believe that, based on some contradictory findings, that measurement may be inaccurate if Polaris Aa is formed from two different stars that merged. In that scenario, the model we use to calculate star age would no longer work and could give wildly inaccurate estimates of the star's true age
TMYK
Right but how did it know to be the pole star?? Huh?
Yeah! Makes ya think!
It had the fastest lap in qualifying.
Max Verstappen approves of this comment.
Unfortunately (or fortunately?) this appears to be untrue.
Polaris is a cluster of stars formed about 2 billion years ago. Sharks originated about 450 million years ago.
One star of Polaris (Aa) appears to be 50 million years old, but it seems likely due to a collision of stars which added mass to it.
So it's technically not wrong.
Thanks for this. Now I’m on a major Wikipedia deep dive on Polaris and cepheid variables!
