The Distribution of Species (Timeline: Life on Earth)

How has the Earth and life on it changed? Why do plants and animals adapt to live in extreme conditions? What is "ballooning"? 'The Distribution of Species' explains why and how things live where they do - from scalding hydrothermal vents to the coldest glaciers. See how "ballooning," exploding, and rafting help species spread from place to place. Understand why rain forests play host to some of the most beautifully ornate dancing birds, and discover how Earth once had just one huge landmass. Life on Earth is constantly changing. It has been doing so for as long as we know and far before humans were here. Through the use of detailed case studies and scientific theories, the books in the 'Timeline: Life on Earth' series discuss how changes are studied, what the evidence reveals, and how such changes have had - and continue to have - an impact on Earth.
