No animal is more symbolic of the Arctic than the Polar Bear. In the short space of 150,000 years, it has undergone behavioural and physiological changes to evolve from a Grizzly Bear into the most specialised predator of the Arctic sea ice. Yet, its survival is now threatened by global warming.Renowned Polar Bear scientist Ian Stirling compresses 40 years of research on these iconic mammals into a new and comprehensive natural history. In accessible language he explains their evolution, life history, behaviour, how they are researched, and the current threat to their very existence.
