RE-RUN: Information, Aliens and the Origin of Life

This is a free preview of a paid episode. To hear more, visit bigbiology.substack.com

This episode was originally published in 2018. It's one of our most popular episodes of all time, so we decided to run it again while we're in between seasons. Look for new Big Bio episodes in August. 

What is life? How did life arise from non-life? What did life look like at its origin?



Tune into this podcast to hear Art and Marty talk with Sara Walker, an expert in astrobiology and theoretical physics at Arizona State University. They discuss how life might have arisen on Earth and why biologists and physicists should work together to find a theory of life.

Her ideas could help decide what to do about artificial intelligence (SPOILER: The robots will take over, but it’s going to be OK). They might also help us find life on other planets.
