Why Birds Evolved Wings: A Remarkable Story of Exaptation 

The stiffer structure of feathers probably allowed for wings to be used in displayed fanning motions as well, and we can only speculate at such behaviors, its within the realm of reasonable speculation to guess that more social dinosaurs may have used flashes of the wings to signal things to each other, most obviously and basic, is probably signaling while trying to find a mate. Birds often share the load of brooding the eggs and chicks, so, large well formed wings would be a sign to each other that they are fit mates to shield the young from the elements. Beyond that, we can imagine that if wings were part of mating wooing and competition between suitors, they may have nipped and plugged at each others wing feathers, much like how birds will pull each others feathers during bullying or fighting.

Good video! Good channel in general. Keep up the good work!

Interesting take.

Will you ever cover fast rotating exoplanets? Its not talked about as much as any tidal planets despite the earth being a fast rotator.

Did you say "Egg Thief"? That damn Kula Ya Ku won't fucking chill. 😭

A very tight opinion on the question!

Beautiful birds thee show here!

How did mesothermic dinosaurs in cold environments(nanuqsaurus, llyelwinnosaura, etc) without flight feathers brood their young?

"A structure adopts a different function than what it originally EVOLVED FOR"... did he really just say that... since when to thing evolve FOR something??? Nature does not make decisions about what to evolve and why... Why do these people get away with saying things like this???
