Plant Evolution at Environmental Extremes

This episode explores how plants survive in Earth’s harshest environments — from Antarctica’s freezing landscapes to the world’s driest deserts. Despite opposite temperature extremes, both ecosystems share one core challenge: severe water scarcity.

We examine adaptations such as antifreeze proteins, CAM photosynthesis, cushion-like growth forms, dormancy, and rapid reproductive cycles. These strategies reveal striking cases of convergent evolution and offer insight into how life persists under extreme stress — and what it may teach us about resilience in a changing climate.
