Sharks Are Literally Older Than Trees

Here is a sentence that will rearrange your brain: sharks are older than trees. Not older than some trees. Older than the entire concept of trees. Sharks first appeared in Earth's oceans around 450 million years ago. Trees didn't show up until about 350 million years ago. That's a 100-million-year head start.

To put that in perspective, sharks were already ancient, established, and thriving when the first woody plant dared to sprout above the ground. The ocean's most famous predator was swimming around before forests were even a rough draft.

Sharks have survived five mass extinction events -- including the one that wiped out the dinosaurs. Through all of it: the asteroid, the ice ages, the continental drift, the dramatic rebranding of entire ecosystems -- sharks mostly just kept doing shark things. They barely changed. Scientists even have a fond nickname for animals like this: living fossils.

The humble tree, meanwhile, has gone through countless evolutionary reinventions. Sharks looked at all that chaos and said: no thanks, we're good. Which is either deeply impressive or the most relaxed attitude in the history of life on Earth. Possibly both.
