Airborne: life takes to the sky
This program analyzes how flight evolved not once but four times, in very different ways. Presenting a number of theories, the program examines how insects, pterosaurs, birds, and bats each took to the sky. Bug wings that may have evolved from larva...
Windows on the mind: children's drawings
Jean Piaget believed that children go through a universal developmental process that is clearly reflected in their drawings. Is Piaget's theory valid, and if so, to what extent does culture influence that process? In this program, Peter Willatts, of...
