The Best Of Our Knowledge #1154

If you are looking for clues to the way life on Earth began, you have to dig deep.  I’m not talking about shovels and picks right now...I’m talking about studying the inner workings of the basic molecules of life: DNA and RNA. Today on The Best Of Our Knowledge, our astro-biology series returns to Earth with an in depth look at these fundamental building blocks of life...and how little we actually know about them.

We’ll also spend an Academic Minute on another evolutionary miracle: gecko feet.
