Did birds really evolve from dinosaurs?

WALT understand about the origin of birds through the Inquiry process.
I know I can do this when I make and answer Inquiry questions about the origin of birds.
Notes
Archaeopteryx shares unique features with theropods.
Theropods were ancestors of birds.
The birds were just a branch on the dinosaur’s tree of life.
Birds evolved from theropod dinosaurs, many of their characteristics have changed.
Theropods are closely related to birds.
One of the evidence that birds evolved from theropod dinosaurs is the changes in the bones of the dinosaurs that evolved into birds.
Birds after Archaeopteryx continued to evolve in some of the same directions as  their theropod ancestors.
