Biology's Biggest Chicken and Egg Problem | Jacob Fine

Life’s First Blueprint Wasn’t DNA; it was RNA.

Today we spoke with Jacob Fine, graduate student researcher in Computational Biology from the University of Toronto. We explore the physics of replication, the role of entropy and information theory, and how modern biology is reconnecting with theory to understand the most fundamental question in science. Our conversation takes place in a Russian sauna, where the hot and humid environment mimics some of the conditions needed for life to begin.
