Last week, we listened to Chapter 2 on The Origin of Life. We fast-forwarded from when the solar system formed to the beginning of life on Earth. We came to understand how life may have originated from the emergence of a single molecule. We looked at experiments that emulated early conditions of the Earth to bring about a molecule we call the replicator. We referred to it as the replicator because unlike most other molecules that formed before it, this molecule was able to replicate itself. We know replicators exist because we are made up of them. DNA molecules are replicators. From there, we now need to ask how replicators like DNA work to understand how organisms like us may have grown and evolved from such humble beginnings. So here now, for you, this Sunday 25th of August 2013, Chapter 3 of The Tyranny of God: Genetics.
