Brad Norman tracked the movements and biology of whales' sharks, one of the largest fish in the world, which is on the verge of extinction. Norman worked with the Australian Marine Conservation Society for his research on whale shark behavior that has helped scientists and managers to understand the impacts of ecotourism on whale sharks and how to minimize these impacts.

The author refutes the popular belief that the evolution mechanism of natural selection is an orderly system of progress. Instead, he uses a variety of species to demonstrate the role of chance in determining which genetic traits survive and get passed on, however unusual or unsuitable for adaptation they may be.
