How do you evolve flight? Archaeopteryx is a famous fossil that is the supposed link between birds and dinosaurs. It had winged claws, teeth, and feathers. They say that the scales evolved into feathers and that is how reptiles evolved flight. Upon further inspection, you can see that feathers and scales are completely different. feather scales <~ mouse over, hard to see with my black background
They happen to be different.
So how did reptiles evolve flight then? Did a dinosaur just run off a cliff and hope that some wings sprouted, oh wait... evolution is gradual change. Wings are arodynamic so that they can fly fast, be light-weight, and still be strong. It needs to be a wing to fly, not a extra long/wide arm. So how did flight evolve?
