Question

Feathers evolved in dinosaur are for insulation against cold weather but later birds adopted feathers for flight? explain this in contact of evolution ?

Answer 1

Answer:

for getting warmth as prevention from cold winds

and aerodynamic in nature which helps them to fly easily and overpowering speed

Answer 2

Answer:Birds' Feathers First Evolved Before Flight, Researchers Say. ... Many paleontologists have argued that pennaceous feathers are so well adapted to move air efficiently that they must have evolved for this purpose after birds' ancestors took up primitive types of flying or gliding.While obviously feathers are pretty critical to powered flight for birds, precursors likely were capable of some form of gliding or at least controlled falling, and obviously feathers would be a massive help there producing a large surface area for relatively little commitment in mass.But the past decade or two of research, which is marked by the discovery of thousands of specimens of early birds and flying dinosaurs, also shows that feathers were an early evolutionary innovation—even if they probably arose for reasons unrelated to powered flight.But unlike fur, proto-feathers became more complex over evolutionary time, branching off with side veins and barbs, and developing extraordinary colours. Today, feathers are phenomenally useful to birds, and not just because they allow flight.
