There is a force in the world everywhere we go, in fact, in the entire universe.

It's complicated. It's very difficult to understand. The mechanisms behind it are not well understood

by the general public. Yes, I'm talking about gravity. It's not just a good idea. It's the law,

but this is not a podcast about gravity. It's a podcast about something that all of us do understand,

deep down, but many of us have a lot of trouble embracing. Hey, it's Seth. And this is a Kimbo.

We'll be back in a second to talk about evolution, the evolution of species and the evolution of ideas.

But first, here's a message from our sponsor.

and I look forward to more hearing of more children involved in the art of origami.

I start with gravity because there are no gravity deniers. Everybody accepts that the earth is

somehow sucking us down and we are able to walk without floating off into space. That a baseball

travels the arc that a baseball travels because somehow gravity is involved. That light things

have less, quote, gravity on them than heavy things. Gravity doesn't have much of a hard time

getting accepted ever since Isaac Newton invented it when an apple dropped on his head because it's

easy to say, of course, we needed a way to explain all the stuff that's going on around us.

And this is as good as any. It's got a name and we can work with it. But evolution,

evolution has been controversial since even before Darwin published his work. Darwin,

whose wife was quite religious, really hesitated for decades to share his ideas because he was
