A natural-history drama in six parts about our understanding of animals and their habits.
Why are some grizzly bears better fishermen than others? What helps sooty terns to locate their nests in a colony of thousands? During this century scientists attempted to answer such questions and revealed the nature of learning.
In Russia Pavlov sought explanations by flashing lights and ringing bells at his dogs, while in America, scientists devised mazes, puzzle boxes and 'one-armed bandits' to explore techniques for moulding behaviour. By rewards they encouraged animals to develop amazing skills.
