Hello, I'm Brian Cox and my aim is to raise the level of scientific discourse on the BBC.

And I'm Robin Inz and my aim is to reduce the level of human anxiety

and the volume of complaints when levels of scientific discourse are raised on the BBC.

Today we're going to be looking at how life began.

That's right, yes, the charade that is life.

Life is the name of the game.

Life to see you, to see you live.

Saturday, Brian, time, here comes science.

You see, that wouldn't have happened if around four billion years ago,

chemistry hadn't got interesting, turned into biology,

and in about some journey towards ever-increasing,

self-replicating complexity that appears,

only appears, my new Robin, to violate the second law of thermodynamics.

Now, you will, of course, be surprised there to Brian say the words,

chemistry, and interesting, so closely together,

because for any regular listeners, they will know that Brian considers biology

to be one of the arts, like contemporary dance or juggling,

another one of the arts.

But since you've actually had a demonstrate moment, haven't you?

And you have now become a lover of photosynthesis to a point with legal ramifications.
