Expert Answer:

There is still no consensus among the scientists about the exact pathway of the evolution of birds. The prevailing theory proposes that birds descended from a group of dinosaurs called theropods. Others contend that birds did not evolve from dinosaurs but rather from a group of small, four-legged, arboreal reptiles called the thecodonts. Still, others feel that birds may not have originated from reptiles at all.
