The study of fossils indicates that the birds evolved from the reptiles long long ago. The discovery of the ‘Archaeopteryx’, the earliest fossil bird and the skeleton of the modern birds, as well as the recent researches have confirmed this belief .Birds are called winged bipeds.
The oldest bird Archaeopteryx is in many ways a connecting link between the two classes. Yet the gap between Archaeopteryx and actual reptilian ancestor is yet to be filled. The development of some birds reveals many remarkable resemblances to that of reptiles. Therefore we conduct conclude that birds evolved from a reptilian stock.
