There is a common misconception that birds evolved directly from dinosaurs, but the truth is that birds evolved from a group of reptiles called archosaurs, which also gave rise to dinosaurs. The earliest known bird-like dinosaur lived over 150 million years ago, and over time, these early birds evolved into the modern-day birds we know today. Cockatiels are not descended from dinosaurs directly, but they are part of the same family of birds that dinosaurs evolved into. Parrots, the family that cockatiels belong to, are believed to have evolved around 70 million years ago, long after the extinction of the dinosaurs. The evolution of parrots is still not fully understood, but scientists believe that the group evolved in the Southern Hemisphere and spread to other parts of the world over time. Parrots are characterized by their unique bill shape, which allows them to crack open hard seeds and nuts. Cockatiels are part of the genus Nymphicus, which includes three other species of birds, al...
