What this episode covers

In this episode, Chris and Abha explore how life originated here on earth and how we might identify it in other parts of the universe. They ask two researchers about the signature characteristics of life and what common dynamics we might see among organisms outside our planet. They’ll also delve into assembly theory, a recent concept that looks at the construction of objects as a way to universally quantify life, which has ignited debate within the scientific community.
