#480 โ€“ Dave Hone: T-Rex, Dinosaurs, Extinction, Evolution, and Jurassic Park

I have a problem with the term apex predator, because ecologically, apex predators are generally defined as things that eat other predators, right?

So a great white shark is because it's eating stuff like tuna and sea lions, which are themselves predators.

Lex Fridman Podcast
#480 โ€“ Dave Hone: T-Rex, Dinosaurs, Extinction, Evolution, and Jurassic Park

So it's a predator of predators.

#480 โ€“ Dave Hone: T-Rex, Dinosaurs, Extinction, Evolution, and Jurassic Park

Whereas people love saying lions are apex predators and they love saying T-Rex is an apex predator.

Lex Fridman Podcast
#480 โ€“ Dave Hone: T-Rex, Dinosaurs, Extinction, Evolution, and Jurassic Park

They're eating herbivores.

This is not some weird and unusual thing.

Lex Fridman Podcast
#480 โ€“ Dave Hone: T-Rex, Dinosaurs, Extinction, Evolution, and Jurassic Park

They're the largest predator in their ecosystem.

Lex Fridman Podcast
#480 โ€“ Dave Hone: T-Rex, Dinosaurs, Extinction, Evolution, and Jurassic Park

And they are a giant one.

My friend Dairon Nash has moved to using the word arch predator.

Lex Fridman Podcast
#480 โ€“ Dave Hone: T-Rex, Dinosaurs, Extinction, Evolution, and Jurassic Park

So it's like some kind of

Lex Fridman Podcast
#480 โ€“ Dave Hone: T-Rex, Dinosaurs, Extinction, Evolution, and Jurassic Park

massive thing but avoiding the term apex because i think that leads into a it it it's a subtle terminology thing but uh an important one i just learned something today so i didn't understand i thought i was i was using the word apex predators but everyone keeps using it when i don't think they should

Lex Fridman Podcast

And now you're getting into linguistics and it's like, well, if everyone uses it to mean that, does it now mean that rather than what it should mean?

Lex Fridman Podcast
#480 โ€“ Dave Hone: T-Rex, Dinosaurs, Extinction, Evolution, and Jurassic Park

And then I'm probably losing that argument because actually you'll probably find way more stuff calling it an apex predator than you will an arch predator.

Lex Fridman Podcast
#480 โ€“ Dave Hone: T-Rex, Dinosaurs, Extinction, Evolution, and Jurassic Park

But here we are.

Lex Fridman Podcast
#480 โ€“ Dave Hone: T-Rex, Dinosaurs, Extinction, Evolution, and Jurassic Park

But you're saying T-Rex didn't eat?

Lex Fridman Podcast
#480 โ€“ Dave Hone: T-Rex, Dinosaurs, Extinction, Evolution, and Jurassic Park

Other predators?

Lex Fridman Podcast
#480 โ€“ Dave Hone: T-Rex, Dinosaurs, Extinction, Evolution, and Jurassic Park

Well, it's probably not going to.

Lex Fridman Podcast
#480 โ€“ Dave Hone: T-Rex, Dinosaurs, Extinction, Evolution, and Jurassic Park

So we can get into, though I'd prefer not to because it's tedious, the argument of whether or not there's these small things which some people have said is a different group called Nanotyrannus or a different species called Nanotyrannus.

Lex Fridman Podcast
#480 โ€“ Dave Hone: T-Rex, Dinosaurs, Extinction, Evolution, and Jurassic Park

But fundamentally...

Lex Fridman Podcast
#480 โ€“ Dave Hone: T-Rex, Dinosaurs, Extinction, Evolution, and Jurassic Park

T-Rex is definitely weird, even compared to all the other giant tyrannosaurs that are very closely related to it, because it is by far, ludicrously by far, the largest carnivore in its ecosystem.
