This Week on Quirks & Quarks

Nov 22 - It's Alive!

4 billion years ago, the world was a grim and lifeless place of unbreathable air, toxic water and bleak rock. But somewhere, somehow, a few simple molecules came together, and began to make copies of themselves. Life was born, and those first simple chemicals eventually transformed into the almost unimaginable complexity of our living world. In this week's feature documentary, we look at how life began on Earth - as scientists explore and begin to understand the first steps that transformed simple minerals, gases and water into teeming life.

Plus - a Canadian scientist discovers that the egg really did come before the chicken.

That's Quirks & Quarks, with host Bob McDonald, Saturday right after the noon news on Radio One, or anytime on our web page.

AND NOW a second opportunity to hear Quirks & Quarks - every Monday night at 11pm on Radio One.
