Question

Some dinosaurs had feathers although they could not fly but birds have feathers that help them to fly. In the context of evolution, we can infer that:

• A. Reptiles have evolved from birds.
• B. There is no evolutionary connection between reptiles and birds
• C. Feathers are homologous structures in both the organisms.
• D. Birds have evolved from reptiles.

Answer 1

The correct option is D Birds have evolved from reptiles.

Reptiles are ancestors of birds, feathers were developed to form an insulating coat on the body so as to prevent the loss of body heat. But later, these feathers became useful in flight. This supported the view that birds are very closely related to the reptiles.
