Feathers: The Evolution of a Natural Miracle
Format: PDF / Kindle (mobi) / ePub
In Feathers, biologist Thor Hanson details a sweeping natural history, as feathers have been used to fly, protect, attract, and adorn through time and place. Applying the research of paleontologists, ornithologists, biologists, engineers, and even art historians, Hanson asks: What are feathers? How did they evolve? What do they mean to us?
Engineers call feathers the most efficient insulating material ever discovered, and they are at the root of biology's most enduring debate. They silence the flight of owls and keep penguins dry below the ice. They have decorated queens, jesters, and priests. And they have inked documents from the Constitution to the novels of Jane Austen.
Feathers is a captivating and beautiful exploration of this most enchanting object.

body-mass-to-wing ratio for a sustained flight!) There is little doubt that theropods could run and leap, but could that strategy have ever provided the thrust and lift required for takeoff? This is the question that keeps the tree-down theory very much alive. “There’s a certain euphoria in the dinosaur community about having solved the problem,” Alan Feduccia told me, but he and other BAND members reject the idea that flight could have evolved in a terrestrial setting. “It’s almost
Ostrich.” Impressed by his distinguished service in the Boer War, as well as his deep knowledge of ostrich farming, they tasked Thornton with finding, capturing, and bringing home alive as many of the birds as sheer logistics would allow. Money was no object. To a powerful group of lawmakers and feather moguls, this mission was seen as no less than the salvation of the South African ostrich industry. Known chiefly by reputation and rumor, the Barbary Ostrich boasted extravagant “double-floss”

For Häberlein, the stakes were high: he was seventy-four years old, a widower, with a daughter at home who required a substantial dowry to marry within her station. Family honor (and a comfortable retirement) required a lucrative sale. For Richard Owen, the stakes were even higher. He was the preeminent

Feathers still feature prominently in military dress uniforms
