#11. Galápagos Tomatoes and the Paradox of Reverse Evolution

Wild tomatoes on the Galápagos may be “evolving backward” – but is reverse evolution even a real thing? In this episode, we trace how Darwin’s volcanic islands inspired the theory of evolution, then follow a new study showing tomatoes on younger, harsher islands shifting toward ancestral chemical defenses. From thin soils and fresh lava to Dollo’s Law, and whales returning to the sea, we explore why evolution has no “forward” or “reverse” – only survival on a planet constantly reshaped by geology.

#10. Banking on the Water Table: America’s Hidden Groundwater

Groundwater is our hidden savings account. Learn how scientists map water-table depth using wells, satellites, and machine learning - and why shallow groundwater across large areas matters for ecosystems, contamination risk, and drought resilience.

#9. Constructive Destruction Meets a Finite Planet

Innovation drives economic growth - but the planet has limits. We translate “creative destruction” into Earth terms: resource booms, energy transitions, and why sustained growth only works long-term if it respects geologic and climate boundaries.

#8. Hydrogen beneath our feet

A clean energy source may be naturally generated underground. We follow the petroleum-style playbook - generation, migration, trapping, drilling - and ask where geologic hydrogen could fit into global and U.S. energy futures.

#7. New Rooms for Chemistry: MOFs, Geology & the Nobel

Why did porous crystal “architectures” win big attention? Meet metal-organic frameworks (MOFs), the mineral connections that inspired them, and how their tiny pores could help with carbon capture, water harvesting, and pollution cleanup.
