Nov 3, 2024

Dr. Michael Lachmann, a Professor at the Santa Fe Institute, dives deep into the origins of evolution and the concept of life itself. He explores how life may have emerged from cosmic selection processes influenced by planetary conditions. The discussion navigates thermodynamics, functional information, and entropy while challenging the definition of 'life.' Lachmann also contemplates the possibility of life beyond Earth and urges a rethinking of timeframes associated with life's beginnings, pushing the limits of conventional scientific understanding.

Episode notes

INSIGHT

Cosmic Selection and Life's Origins

Life emerges as a generalized cosmic selection process shaped by planetary conditions.
This process involves thermodynamics, functional information, and entropy.

INSIGHT

Life's Tight Link with Function

Life and function are tightly linked.
Function is an emergent property used by life.

INSIGHT

Information as Uncertainty Reduction

Information is a reduction in uncertainty, exemplified by a die roll.
This reduction in possibilities represents a quantifiable amount of information.

Today we're digging into the deep and often overlooked connections between neodarwinian evolution, life’s origins, and the evolution of non-living systems. We're guided by Dr. Michael Lachmann of the Santa Fe Institute, who investigates how life may have begun as a more generalized cosmic selection process, with planetary conditions shaping its emergence and survival. Through discussions of thermodynamics, functional information, and entropy, we examine whether life might be present in forms beyond Earth’s biology - and how'd know what to look for. In the end, this discussion swirls around what it means to be “alive” and how we can narrow boundaries of "life" to get closer to a true scientific definition of it.

When not talking to brilliant people or making movies, she spends her time painting, reading, and guiding backcountry excursions. Shilo also did his PhD at Columbia studying the elastic properties of molecular water. When he's not in the film studio, he's exploring sound in music. They are both freelance professors at various universities. - Blog: http://DemystifySci.com/blog - RSS: https://anchor.fm/s/2be66934/podcast/rss - Donate: https://bit.ly/3wkPqaD - Swag: https://bit.ly/2PXdC2y SOCIAL: - Discord: https://discord.gg/MJzKT8CQub - Facebook: https://www.facebook.com/groups/DemystifySci - Instagram: https://www.instagram.com/DemystifySci/ - Twitter: https://twitter.com/DemystifySci MUSIC: -Shilo Delay: https://g.co/kgs/oty671
