How Did Birds Evolve?

The video explores the evolution of theropod dinosaurs, highlighting their bipedal nature and the development of feathers for insulation. It discusses the transition from gliding to powered flight in early birds, supported by micro Raptor fossils. The evolution of bird anatomy, including the transformation of toothed jaws into beaks, is also covered, illustrating how modern birds descended from theropods.

Which characteristic is shared by both theropods and modern birds like the Roadrunner?

• Lack of feathers

• Herbivorous diet

• Bipedalism

• Quadrupedal movement

What was the initial purpose of feathers in theropods?

• To provide insulation

• To help in swimming

• To enable flight

• To camouflage

How did micro Raptor likely move between trees?

• By gliding

• By flying

• By running

• By jumping

What evolutionary change helped birds become experts in powered flight?

• Increase in body size

• Evolution of lightweight beaks

• Growth of larger tails

• Development of scales

What is the relationship between theropods and modern birds?

• Modern birds are descendants of theropods

• Theropods are unrelated to modern birds

• Theropods are direct ancestors of reptiles

• Theropods evolved from modern birds
