Paul Davies on the "DNA Conundrum"

We will be offering a review of J. Warner Wallace's new book God's Crime Scene in the coming days and while reading through the book I was challenged by the following quote by Paul Davies on the DNA "chicken and egg" problem:

"Take DNA...It has a grand agenda, but to implement this, DNA must enlist the help of proteins...proteins are made by complicated machines called ribosomes, according to coded instruction received from DNA via mRNA. The problem is, how could proteins get made without DNA code for them, the mRNA to transcribe the instructions, and the ribosomes to assemble them?  But if the proteins are not already there, how can DNA, ribosomes and all the rest of the paraphernalia get made in the first place?  It's Catch-22." [1]

Courage and Godspeed,
