About
With teacher's guide
Traces the evolutionary relationship between birds and reptiles, and explains how the bird's skeletal structure gradually adapted to the requirements of flight. Uses close-up photography, animated drawings, and laboratory experiments to show that birds are able to live in a wide variety of environmental niches because of their behavioral instincts and the adaptations of structural features
