What Is Life? #4: How Did Life Begin?

“What Is Life?” is an eight-episode podcast series recorded in front of a live audience. (Subscribe to the podcast at iTunes, via RSS, etc.)

In this episode, I spoke to astrobiologist Caleb Scharf, the director of the Columbia Astrobiology Center at Columbia University, about how life began. We don’t know how life got its start, but Scharf argues that emerging evidence leaves only a few theories as leading contenders.
