What is an animal that evolved from the lungfish?

While lungfish themselves are ancient and haven't "evolved into" anything currently living, they are considered to be closely related to the ancestors of all tetrapods, which are four-limbed vertebrates. This includes:

* Amphibians: Frogs, toads, salamanders, and newts.

* Reptiles: Lizards, snakes, turtles, crocodiles, and dinosaurs.

* Birds: All birds evolved from a lineage of dinosaurs.

* Mammals: Including humans.

So, in a way, all of those animals evolved from the same lineage that lungfish are part of. It's not that lungfish directly evolved into any of these groups, but rather that they share a common ancestor.

Think of it like this: Your cousins are your relatives, but you didn't evolve from them directly. Instead, you both share a common ancestor (your grandparents). Similarly, lungfish and tetrapods share a common ancestor that lived millions of years ago.
