The first birds

Birds such as Archaeopteryx appear about 150 million years ago. They branched off from small feathered dinosaurs: birds are the dinosaurs that survived. Flying reptiles came before them, about 228 million years ago, and winged insects long before that. Whales came from land mammals about 50 million years ago.
