If evolution is true why do birds have wings and feathers instead of big teeth and scales?

these wacked out evolutionists keep saying birds are descended from dinosaurs well i have a question why do birds have wings and feathers no scales or big roars?
HAHAH i just can’t help myself. ladybug, you are so wrong. newton’s laws are regarding intertia, force and acceleration being proportional, and equal/opposite reactions.

entropy is a law of thermodynamics.

and a theory is fact in science.
inertia
entropy is part of the 2nd law of thermo i should say

there is a bird in south america that has claws on its wings and is not a good flier like the first bird/dinosaur and digest its food slowly and eats leaves also like a dinosaur,
