The Builders

And here to help me is Ben Goldfarb, who's a writer.

Radiolab
The Builders

And beaver believer.

Radiolab
The Builders

Don't stop be believing.

So Jose, he waddles out into the world with little webbed feet and whiskers and very large buck teeth that are bright orange because apparently... Beavers teeth actually contain iron.

Radiolab
The Builders

Yeah, like a chisel.

Radiolab
The Builders

The iron makes their teeth excellent for chopping down trees.

Radiolab
The Builders

Because beavers have one single obsessive haru.

Radiolab
The Builders

It's not drawing or knitting or doing puzzles.

Radiolab

A dam is basically a wall in the water that beavers build by dragging the trees that they chomp down across a flowing stream, blocking the water, and sometimes adding mud or other stuff to keep that wall sealed up tight.

Radiolab
The Builders

A beaver dam makes water accumulate behind the barricade, turning a trickling stream into a new pond in the middle of the forest.

Radiolab
The Builders

Ana, can I just interrupt to ask why?

Radiolab
The Builders

Like, I've always wondered this about beavers.

Radiolab
The Builders

Like, a beaver like Jose, why is it driven to go through all this work to chop down trees and make a wall that creates pools?

Radiolab
The Builders

It just feels so random.

Radiolab
The Builders

According to Ben, it all stems from the fact that beavers are super awkward on land.

Radiolab
The Builders

With their webbed feet and huge tail that drags on the ground, beavers are not good at running, making them easy pickings for land predators.

Radiolab
The Builders

By making dams, they create deep pools of water, which allows them to transform from wobbly wolf snacks into elegant professional swimmers who can spin and twirl and can hold their breath for up to 15 minutes.
