Answer 1

The statement, the first feathered ancestors to birds did not fly, but may have used their feathers for insulation and display best describes how flight and feathers are related in the evolution of birds.

Theropod dinosaurs gave rise to birds throughout the Jurassic Period, and rather than developing suddenly, the basic bird body type of tiny, light, feathered, and wings evolved gradually over many millions of years. Early birds evolved during the Jurassic and Cretaceous periods, becoming skilled flyers with accelerated growth rates, but they were wiped off along with their close dinosaur relatives at the end of the Cretaceous period. Following the mass extinction, contemporary birds underwent a rapid diversification process that resulted in the current global distribution of more than 10,000 species.
