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

But no.

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

But I think an awful lot of people know and are now kind of used to it as an idea.

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

So what's evolutionary, the connection between birds and dinosaurs?

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

I mean, they literally are in the same way that we are apes and mammals.

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

Birds are dinosaurs.

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

The...

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

direct, if you trace back the evolution of all the birds, so hummingbirds and albatross and ostrich and kiwi and parrots and pelicans and penguins and whatever else, and take them down to their ancestral point, and then go back quite a few more million years...

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

their nearest relish to them is a dinosaur.

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

It is actually something very close to Velociraptor, or at least a small version of Velociraptor.

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

So the birds have literally descended from dinosaurs, therefore they are dinosaurs.

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

We have literally descended from other apes, we are apes.

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

It is that form of evolutionary connection.

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

Feathers are in Tyrannosaurs, so feathers go back at least... So ironically,

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

because the fossil record is very incomplete.

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

Most of the things that are closest to birds, we know from the early and late Cretaceous.

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

So the last kind of 50 million years of dinosaur evolution up to the extinction.

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

And actually birds almost certainly go back another 50 million years.

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

So birds did not appear as a result of the dinosaurs going extinct.

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

Birds lived alongside the dinosaurs for a hundred million years.

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

The birds were not new on the scene, and it's all like, oh, the dinosaurs died, and from the ashes rose the birds.
