Title: Feathers
Author: Thor Hanson
Category: Nature, Climate & Environment

Did you know that feathers predate flight by millions of years? Sam and Sophie dive into Thor Hanson's Feathers, a book that reveals how these incredible structures started as simple insulation and became a language of color, a driver of conservation, and an inspiration for aviation.

They walk through the evolution of feathers from dinosaur filaments to the self-repairing protein zippers we see today. The episode covers the engineering of a single feather, the diversity of feather types, the hidden UV patterns birds see, and the surprising role of feathers in human history—from the quill pen to the Audubon Society.

If you've ever wondered why birds have feathers or how a single structure can be so versatile, this episode will change how you see every bird you pass. The takeaway: feathers are a window into evolution's creativity, serving survival, communication, and culture.
