Approximately how long did it take from the time the first feather evolved until the first animal took flight?
a. 1 million years
b. 1000,000 years
c. 50 million years
d. 500 years

The answer is C. 

It took approximately 50 million years for feathers to evolve into being able to be used for flight. It started with dinosaurs running up an incline and flapping their feathered arms to provide extra speed. To gliding short distances from a high point. To the ability to fly short distances. To the ability to fly far distances (modern birds). This process took 50 million years.

Hope this helped. Have a great day!
