Extinctions of Living Things (Timeline: Life on Earth)

How has the Earth and life on it changed? What is a “living fossil”? Why did the dinosaurs become extinct? ‘Extinctions of Living Things’ looks into the evolution of living things and the disappearances of species, the effect humans have on extinctions, and how modern scientists are striving to protect threatened species. Look into catastrophic ecological changes that blitzed species, study fossils of giant sea creatures, judge if we are to blame for the disappearance of the dodo, and assess if dinosaurs are still alive today. 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.
